Small RNAs have a big impact on regeneration. (2/139)

A number of lower vertebrates including urodele amphibians and teleost fish are remarkably adept at repairing and regenerating damaged tissues and organs. Freshwater planarians are even more amazing, capable of regenerating entire body plans from small amputated fragments. In contrast, mammalian regenerative capacity is quite limited but of intense interest, especially related to human health and disease. For those organisms capable of robust regeneration, a common theme is the use of stem cells to replace complex tissues. Key questions remain as to the origin of these cells, whether there are pools of such cells that migrate to injured regions or whether they are generated on site. Beyond their origin, how are the genetic pathways that enable differentiation into multiple cell types and tissues regulated? microRNAs (miRNAs) are small noncoding RNAs that have recently been shown to play important roles in controlling stem cell self-renewal, proliferation and differentiation. Some of these are thought to be required to maintain "stemness". Here, we summarize recent work on the role of miRNAs in stem cells and their roles during regeneration.  (+info)

Pathological study on the scuticociliatosis affecting farmed Japanese flounder (Paralichthys olivaceus) in Japan. (3/139)

Pathological findings associated with scuticociliatosis in farmed Japanese flounder in Japan are described. Ten moribund fishes, farmed in Tottori Prefectural Fisheries Experimental Station, showed cutaneous ulcers, darkened skin, fin and tail rot, exophthalmia and alterations in swimming behaviour. Histopathologically, severe epidermal degeneration and necrosis, hyperplasia of branchial epithelium, myositis, myelitis, encephalitis associated with heavy accumulation of scuticociliates in the periorbital cavity and optic nerve fiber were observed. Moreover, masses of ciliates were found to feed on the host tissues such as skeletal muscles, gills and brain, causing severe degenerative changes associated with abundant neutrophilic and lymphocytic infiltration. These findings suggest that the present scuticociliate, Miamiensis avidus, is a highly invasive and destructive pathogen infecting Japanese flounder and capable of developing systemic fatal infection.  (+info)

Notch regulates blastema proliferation and prevents differentiation during adult zebrafish fin regeneration | DevelopmentNotch regulates blastema proliferation and prevents differentiation during adult zebrafish fin regeneration | Development
Zebrafish have the capacity to regenerate several organs, including the heart and fins. Fin regeneration is epimorphic, involving the formation at the amputation plane of a mass of undifferentiated, proliferating mesenchymal progenitor-like cells, called blastema. This tissue provides all the cell types that form the fin, so that after damage or amputation the fin pattern and structure are fully restored. How blastema cells remain in this progenitor-like state is poorly understood. Here, we show that the Notch pathway plays an essential role during fin regeneration. Notch signalling is activated during blastema formation and remains active throughout the regeneration process. Chemical inhibition or morpholino-mediated knockdown of Notch signalling impairs fin regeneration via decreased proliferation accompanied by reduced expression of Notch target genes in the blastema. Conversely, overexpression of a constitutively active form of the Notch1 receptor (N1ICD) in the regenerating fin leads to ...

shark fin trade Archives - Saltwater Lifeshark fin trade Archives - Saltwater Life
I have written before about the origins of shark fin soup, however it is worth re-capping slightly: The cartilage in the fins is usually shredded and used primarily to provide texture and thickening to shark fin soup, a traditional Chinese soup or broth dating back to the Song Dynasty (960-1279). The dish is considered a luxury item embodying notions of hospitality, status and good fortune.. The origin of the dish can be traced to the Emperor Taizu of the Northern Song, who reigned from 960-976. It is said that he established shark fin soup to showcase his power, wealth and generosity. The dishs popularity increased during the Ming Dynasty (1368-1644) as a result of an admiral of the imperial navy; Zheng He, who commanded expeditionary voyages around Asia and East Africa from 1405-1433, bringing back fins that fishermen had discarded. From this point onwards shark fin soup became an established dish and by the time of the Qing Dynasty (1644-1912) was in high demand.. It is not surprising that ...

Locomotion in Sturgeon: Function of the Pectoral Fins by C. D. Wilga and G. V. LauderLocomotion in Sturgeon: Function of the Pectoral Fins by C. D. Wilga and G. V. Lauder
Pectoral fins are one of the major features of locomotor design in ray-finned fishes and exhibit a well-documented phylogenetic transition from basal to derived clades. In percomorph fishes, the pectoral fins are often used to generate propulsive force via oscillatory movements, and pectoral fin propulsion in this relatively derived clade has been analyzed extensively. However, in the plesiomorphic pectoral fin condition, exemplified by sturgeon, pectoral fins extend laterally from the body in a generally horizontal orientation, have been assumed to generate lift to balance lift forces and moments produced by the heterocercal tail, and are not oscillated to generate propulsive force. The proposal that pectoral fins in fishes such as sturgeon generate lift during horizontal locomotion has never been tested experimentally in freely swimming fishes. In this paper, we examine the function of pectoral fins in sturgeon swimming at speeds from 0.5-3.0 Ls-1, where L is total body length. Sturgeon were studied

Their common quality may be the adipose fin, which can be found for the dorsal midline between caudal and dorsal fin, although a complete of 6000 varieties from eight purchases from the Teleostei all have an adipose fin [2]. Many artificially bred juvenile salmonids are released into sea-ranching methods every single complete year to create 4.4 million a great deal of top-class food fish [3]. Furthermore, vast amounts of salmonids are released in stock-enhancement or restocking tasks [4]. Many of these pets are tagged to monitor the achievement of these studies or indicate possession relations [5] also to determine escapees from aquaculture farms. Those are believed as ...

Sexually dimorphic breeding tubercles (BTs) are keratinized epidermal structures that form clusters on the dorsal surface of the anterior rays of zebrafish male pectoral fins. BTs appear during sexual maturation and are maintained through regular shedding and renewal of the keratinized surface. Following pectoral fin amputation, BT clusters regenerate after the initiation of revascularization, but concomitantly with a second wave of angiogenesis. This second wave of regeneration forms a web-like blood vessel network that penetrates the supportive epidermis of BTs. Upon analyzing the effects of sex steroids and their inhibitors, we show that androgens induce and estrogens inhibit BT cluster formation in intact and regenerating pectoral fins. Androgen-induced BT formation in females is accompanied by the formation of a male-like blood vessel network. Treatment of females with both androgens and an angiogenesis inhibitor results in the formation of undersized BT clusters when compared with females ...

Fin - WikipediaFin - Wikipedia
A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluid media. Fins are also used to increase surface areas for heat transfer purposes, or simply as ornamentation. Fins first evolved on fish as a means of locomotion. Fish fins are used to generate thrust and control the subsequent motion. Fish, and other aquatic animals such as cetaceans, actively propel and steer themselves with pectoral and tail fins. As they swim, they use other fins, such as dorsal and anal fins, to achieve stability and refine their maneuvering. Foil shaped fins generate thrust when moved, the lift of the fin sets water or air in motion and pushes the fin in the opposite direction. Aquatic animals get significant thrust by moving fins back and forth in water. Often the tail fin is used, but some aquatic animals generate thrust from pectoral ...

Dorsal fin - WikipediaDorsal fin - Wikipedia
A dorsal fin is classified as a medial, unpaired fin that is located on the midline of the backs of some aquatic vertebrates. In development of the embryo in teleost fish, the dorsal fin arises from sections of the skin that from a caudal fin fold.[4] The larval development and formation of the skeleton that support the median fins in adults result in pterygiophores. The skeletal elements of the pterygiophore includes basals and radials. The basals are located at the base of the dorsal fin, and are closest to the body. The radials extend outward from the body to support the rest of the fin.[4] These elements serve as attachment sites for epaxial muscles.[5] The muscles contract and pull against the basals of the pterygiophores along one side of the body, which helps the fish move through water by providing greater stability.[5] In these types of fish, the fins are made of 2 main components.[5] The first component is the dermal fin rays known as lepidotrichia, and the endoskeletal base with ...

Sharks are among the most threatened of marine species worldwide due to unsustainable overfishing. They are primarily killed for their fins alone, to fuel the growing demand for shark fin soup, which is an Asia delicacy. A new study by University of Miami (UM) scientists in the journal Marine Drugs has discovered high concentrations of BMAA in shark fins, a neurotoxin linked to neurodegenerative diseases in humans including Alzheimers and Lou Gehrig Disease (ALS). The study suggests that consumption of shark fin soup and cartilage pills may pose a significant health risk for degenerative brain diseases.. Shark fins are primarily derived through finning, a practice where by shark fins are removed at sea and the rest of the mutilated animal is thrown back in the water to die, said co-author Dr. Neil Hammerschlag, research assistant professor of Marine Affairs & Policy and director of the RJ Dunlap Marine Conservation Program (RJD) at UM. Estimates suggest that fins from as many as 70 million ...

The Dlx5 and Dlx6 genes encode homeodomain transcription factors essential for the proper development of limbs in mammalian species. However, the role of their teleost counterparts in fin development has received little attention. Here, we show that dlx5a is an early marker of apical ectodermal cells of the pectoral fin buds and of the median fin fold, but also of cleithrum precursor cells during pectoral girdle development. We propose that early median fin fold establishment results from the medial convergence of dlx5a-expressing cells at the lateral edges of the neural keel. Expression analysis also shows involvement of dlx5a during appendage skeletogenesis. Using morpholino-mediated knock down, we demonstrate that disrupted dlx5a/6a function results in pectoral fin agenesis associated with misexpression of bmp4, fgf8a, and1 and msx genes. In contrast, the median fin fold presents defects in mesenchymal cell migration and actinotrichia formation, whereas the initial specification seems to occur

THE MYSTERIOUS LITTLE FATTY FIN | Journal of Experimental BiologyTHE MYSTERIOUS LITTLE FATTY FIN | Journal of Experimental Biology
Sitting on the back of many fishes, in between the dorsal fin and the tail, is an enigmatic little fatty flap of skin called the adipose fin. It looks a bit like an extra dorsal fin, and though its present in eight large groups of fishes, no one knows why its there. It might help prevent flow from wrapping over the top of the fish; it might help counteract forces from the anal fin, which is in about the same place, but on the ventral side; it might be a flow sensor; or it might not do anything, persisting due to developmental constraints. Whatever the fins function, most fisheries scientists think its not terribly important, because they regularly snip it off to mark millions of hatchery fish released into the wild each year.. Thomas Reimchen and Nicola Temple at the University of Victoria in Canada devised a simple test to find out how important the adipose fin really is. They swam steelhead trout at speeds between about one and three body lengths per second, measured the tail beat ...

Giant oarfish - WikipediaGiant oarfish - Wikipedia
This species is the worlds longest bony fish, reaching a record length of 11 m (36 ft); however, unconfirmed specimens of up to 17 m (56 ft) have been reported.[7] It is commonly measured to 3 m (9.8 ft) in total length. The maximum recorded weight of a giant oarfish is 270 kg (600 lb).[7] Its shape is ribbonlike, narrow laterally, with a dorsal fin along its entire length from between its eyes to the tip of its tail. The fin rays are soft and may number up to 400 or more. At the head of the fish, the rays are lengthened forming a distinctive red crest. Its pectoral and pelvic fins are nearly adjacent. The pectoral fins are stubby while the pelvic fins are long, single-rayed, and reminiscent of an oar in shape, widening at the tip. Its head is small with the protrusible jaw typical of lampriformes; it has 40 to 58 gill rakers, and no teeth.[8] The organs of the giant oarfish are concentrated toward the head end of the body, possibly enabling it to survive losing large portions of its tail.[7] ...

Tiktaalik roseae: Q&A Session with Neil ShubinTiktaalik roseae: Q&A Session with Neil Shubin
Q: Would you describe the unique physical characteristics of Tiktaalik?. A: When we look at this creature what we see is a mosaic of fish features and those we find in land living animals. Lets look at the fish parts first. There are scales like a fish; you can see they look like chain mail here. There are even scales on the fin. But the other thing that is very fish-like is that it has a fin. There is the fin. See these little bones here; those are fin-rays that you even see in fishes like salmon and trout and so forth. So it has scales and fins like a fish. Now, like land-living animals, it has a few things that are quite different. A flat head with eyes on top. It has a neck. Fish have a situation where the head is actually physically attached to the shoulder. What we have in this creature, and you can see it in the skeleton, is that you have a head that is actually separate from the shoulder, meaning that it has a neck that can move the head around. Other interesting features are that ...

Development and evolution of the muscles of the pelvic finDevelopment and evolution of the muscles of the pelvic fin
Locomotor strategies in terrestrial tetrapods have evolved from the utilisation of sinusoidal contractions of axial musculature, evident in ancestral fish species, to the reliance on powerful and complex limb muscles to provide propulsive force. Within tetrapods, a hindlimb-dominant locomotor strategy predominates, and its evolution is considered critical for the evident success of the tetrapod transition onto land. Here, we determine the developmental mechanisms of pelvic fin muscle formation in living fish species at critical points within the vertebrate phylogeny and reveal a stepwise modification from a primitive to a more derived mode of pelvic fin muscle formation. A distinct process generates pelvic fin muscle in bony fishes that incorporates both primitive and derived characteristics of vertebrate appendicular muscle formation. We propose that the adoption of the fully derived mode of hindlimb muscle formation from this bimodal character state is an evolutionary innovation that was ...

Petition · Ban the possession, distribution and sale of shark fins. · Change.orgPetition · Ban the possession, distribution and sale of shark fins. · Change.org
Shark finning is the practice of cutting off a sharks dorsal fin so that people can use it for shark fin soup or other delicacies. The sharks are often still alive while their fins are cut off with no regard to their pain. They are then tossed back into the ocean where, bleeding and in pain, they either suffocate from lack of mobility or are eaten by other sea predators.. Shark populations have been decimated by finning and many species are nearing extinction. Ecosystems are being upset by the lack of sharks in their waters and we are coming dangerously close to no longer having these beautiful creatures in continued decades.. We are calling for the Idaho State Senate to pass legislation that bans the sale, dsitribution, trade and possession of shark fins. The other West coast states have all passed legislation against shark fins, including Hawaii, Washington, Oregon and California. We want Idaho to join the West coast in becoming more compassionate, thoughtful and responsible in regards to ...

Governor signs shark fin ban - SFGateGovernor signs shark fin ban - SFGate
The practice of cutting the fins off of living sharks and dumping them back in the ocean is not only cruel, but it harms the health of our oceans, Brown said. Researchers estimate that some shark populations have declined by more than 90 percent, portending grave threats to our environment and commercial fishing. Shark fins are used to make shark fin soup, an expensive Chinese delicacy that is popular at special events like weddings. [...] proponents argued that shark populations are being decimated by fishing because of the valuable fins, which sell for hundreds of dollars per pound.

Sharks are among the most threatened groups of marine species. Populations are declining globally to support the growing demand for shark fin soup. Sharks are known to bioaccumulate toxins that may pose health risks to consumers of shark products. The feeding habits of sharks are varied, including fish, mammals, crustaceans and plankton. The cyanobacterial neurotoxin β-N-methylamino-L-alanine (BMAA) has been detected in species of free-living marine cyanobacteria and may bioaccumulate in the marine food web. In this study, we sampled fin clips from seven different species of sharks in South Florida to survey the occurrence of BMAA using HPLC-FD and Triple Quadrupole LC/MS/MS methods. BMAA was detected in the fins of all species examined with concentrations ranging from 144 to 1836 ng/mg wet weight. Since BMAA has been linked to neurodegenerative diseases, these results may have important relevance to human health. We suggest that consumption of shark fins may increase the risk for human exposure to the

Batoid locomotion: effects of speed on pectoral fin deformation in the little skate, Leucoraja erinacea | Journal of...Batoid locomotion: effects of speed on pectoral fin deformation in the little skate, Leucoraja erinacea | Journal of...
Batoids (rays, skates, guitarfishes and sawfishes) are cartilaginous fishes characterized by dorso-ventrally flattened bodies, with expanded pectoral fins fused to the cranium that form a disc ranging in shape from round to rhomboidal (Aschliman et al., 2012; Franklin et al., 2014; Nakamura et al., 2015). Most rays and all skates use their pectoral fins to swim and can be placed into a continuum between undulatory and oscillatory, based on the number of kinematic waves present on the wing during steady locomotion (Rosenberger, 2001). Undulatory (or rajiform) locomotion is often observed in benthic species and is defined by having more than one propulsive wave present on the fin at one time, while oscillatory (or mobuliform) locomotion is most commonly observed in pelagic species and is defined by having less than a half wave present on the flapping pectoral fin disc (Rosenberger, 2001; Schaefer and Summers, 2005). The rajiform mode is specialized for efficient swimming at low speeds, because of ...

International conservation group WildAid and the Singapore Environment Council today launched a new report and public service campaign to raise the alarm that sharks continued to be slaughtered in vast numbers to supply shark fin soup. Analysis of trade data indicated that fins from between 40 to 70 million sharks are being used annually for soup.. There are currently 126 shark species (one third) classified as being at risk of extinction either critically endangered, endangered or vulnerable by the International Union for the Conservation of Nature. Nine more species were added in the last few months; the scalloped hammerhead, the common and big-eyed thresher, the short-fin mako, the silky, the smooth hammerhead, the dusky, the tiger and the bull shark.. The groups stated that while many people in Hong Kong, Singapore, Thailand and Taiwan had reduced eating it due to conservation, health and animal cruelty concerns the market was vast and growing due to Chinas economic boom.

By John Schwedes. Each year tens of millions of sharks are brutally killed for their fins. The fins are used in an Asian delicacy, shark fin soup. The shark fin has no nutritional value, is tasteless since it cartilage and is cooked until it turns gelatinous. The sharks are caught and their fins are cut off the live shark and the still living shark is thrown back into the ocean to endure a slow painful death by starvation or drowning. Currently one third of all the pelagic shark species are on the endangered species list. There has been up to a 90% decrease in population in many of the 400 different species of sharks. Sharks are a vital part of a healthy marine ecosystem, sharks feed on the sick and weak, thereby keeping the schools of fish on which they feed healthy. Sharks being apex predators reproduce slowly and produce a just a few offspring making them especially vulnerable to this devastating assault on their population ...

Inverse Dynamics-Based Fuzzy Logic Control of a Projectile Smart Fin by Mohamed B. Trabia, Surya Kiran Parimi et al.Inverse Dynamics-Based Fuzzy Logic Control of a Projectile Smart Fin by Mohamed B. Trabia, Surya Kiran Parimi et al.
A smart fin for a subsonic projectile should be able to produce maneuvering force and moment that can control its rotation during flight. Piezoelectric actuator is an attractive alternative to usual hydraulic actuators due to its simplicity. The cantilever-shaped actuator can also be fully enclosed within the hollow fin. It has an end fixed to the rotation axle of the fin while the other end is pinned at the tip of the fin. A dynamic model of the system, including external moment due to aerodynamic effects, is obtained using the finite element approach. This paper presents a novel approach for automatically creating fuzzy logic controllers for the fin. This approach uses the inverse dynamics of the smart fin system to determine the ranges of the variables of the controllers. Simulation results show that the proposed controller can successfully drive smart fin under various operating conditions.

Positional cloning of a temperature-sensitive mutant emmental reveals a role for sly1 during cell proliferation in zebrafish...Positional cloning of a temperature-sensitive mutant emmental reveals a role for sly1 during cell proliferation in zebrafish...
Here, we used classical genetics in zebrafish to identify temperature-sensitive mutants in caudal fin regeneration. Gross morphological, histological, and molecular analyses revealed that one of these strains, emmental (emm), failed to form a functional regeneration blastema. Inhibition of emm function by heat treatment during regenerative outgrowth rapidly blocked regeneration. This block was associated with reduced proliferation in the proximal blastema and expansion of the nonproliferative distal blastemal zone. Positional cloning revealed that the emm phenotype is caused by a mutation in the orthologue of yeast sly1, a gene product involved in protein trafficking. sly1 is upregulated in the newly formed blastema as well as during regenerative outgrowth. Thus, sly1 is essential for blastemal organization and proliferation during two stages of fin regeneration ...

We have characterized two new members of the Hedgehog (Hh) family in zebrafish, ihha and dhh, encoding for orthologues of the tetrapod Indian Hedgehog (Ihh) and Desert Hedgehog (Dhh) genes, respectively. Comparison of ihha and Type X collagen (col10a1) expression during skeletal development show that ihha transcripts are located in hypertrophic chondrocytes of cartilaginous elements of the craniofacial and fin endoskeleton. Surprisingly, col10a1 expression was also detected in cells forming intramembranous bones of the head and in flat cells surrounding cartilaginous structures. The expression of col10a1 in both endochondral and intramembranous bones reflects an atypical composition of the extracellular matrix of the zebrafish craniofacial skeleton. In addition, during fin ray regeneration, both ihha and col10a1 are detected in scleroblasts, osteoblast-like cells secreting the matrix of the dermal bone fin ray. The presence of cartilage markers suggests that the dermal fin ray possesses an ...

Quality sunfish initiative | Minnesota DNRQuality sunfish initiative | Minnesota DNR
The DNR wants anglers to weigh in on the second round of proposals comprising the quality sunfish initiative.. In March 2021, nearly 100 lakes received bag limit reductions. Now, the DNR is proposing another 50 lakes for reductions that would go into effect in March of 2022. Some lakes have complementary crappie regulation proposals.. For years, anglers have been telling the DNR they are satisfied with sunfish/bluegill numbers. But an increasing number of anglers are concerned about sunfish size quality.. The prevalent use of electronic fish finders and other technological advancements combined with rapid social media communication have heightened those concerns.. With the quality sunfish initiative, fisheries managers aim to increase the number of lakes with reduced bag limits from 60 to approximately 200 by 2023. Managers are using proven daily limits of five or 10 sunfish to protect and improve sunfish quality on select lakes with both biological potential to produce large sunfish and strong ...

It is documented that this catfish has 40-70 mandibular teeth which are described as being short, uncuspid and arranged in 6-8 short transverse rows. It has three pairs of barbels which are described as being short, with the maxillary barbels having a small membrane at the base. The mandibular barbels have slender ramifications. Synodontis polli is described as having a cusp on the dorsal edge of the humeral process. The dorsal fin is described as having 7 soft rays. The pectoral fin is described as having 8-9 soft rays. The caudal fin is described as being forked with rounded lobes. ...

The Effect of 17b-Estradiol on the Development of Modified Hemal Spines in Early-Life Stage Gambusia holbrookiThe Effect of 17b-Estradiol on the Development of Modified Hemal Spines in Early-Life Stage Gambusia holbrooki
The morphologic development of the gonopodium of male mosquitofish, Gambusia holbrooki, is essential for proper reproductive function and has previously been used as a biomarker for the presence of endocrine-disrupting chemicals (EDCs) in freshwater systems. The development of the gonopodium is accompanied by the modification of the hemal spines on the 14th, 15th, and 16th vertebrae. These form an anchor for the movement of the gonopodium, and their normal development is therefore critical. This development is under hormonal control. It has been hypothesized that the modification of the hemal spines may be used as an end point for understanding the effects of exposure of early-life stage fish to EDCs and to add to the understanding of the differential sensitivities of different life stages. Larval fish were exposed to concentrations (0, 20, 100, and 500 ng/L) of 17b-estradiol (E2) in two experiments using a flow-through system for 8 and 12 weeks. There was a general delay in the development of ...

Ultraviolet rays are an invisible form of radiation streaming from the sun. There are three ranges of UV ray lengths: UVA, UVB, and UVC. UVA is the most abundant; this form can penetrate past the top layer of skin. Researchers believe that UVA can damage the bodys connective tissue, boosting a persons risk for developing skin cancer. Much of the UVB rays are absorbed by the ozone layer in the earths atmosphere. The UVB rays that do reach your skin can be damaging, even though they dont penetrate as deeply as UVA. UVC is very hazardous to the skin, but fortunately, all of these rays are absorbed by the ozone layer ...

The fins have no colour and the upper-side is a brownish-red. A wide single stripe extends along each side of the fish from the upper parts of the eye to just below the Adipose fin. This stripe can appear sea-green, yellow-green or turquoise-blue, depending on the angle that the light hits it. Below this stripe is a wide bright Red band that can be seen on the lower half of the body , running from the underside of the mouth including the throat, and all the way back to the base of the Caudal fin. This fish is often confused with the Neon tetra, but in the Neon the bright red band is shorter, only running to the middle of the body ...

Our group focuses on the study of the cellular and molecular mechanisms controlling limb development and fin regeneration. We are trying to understand how the main signalling centre in limb development, the Apical Ectodermal Ridge (AER), is established and maintained through development and how different molecules, namely those related to stemness, are involved in these processes. Also, we have developed a line of research directed to depict how ion dynamics can control limb development, digit differentiation and fin regeneration. In these studies we use the chicken and zebrafish embryos as well as adult zebrafish as animal models.. ...

In this study, we estimated genetic parameters for direct and social genetic effects for growth traits and fin damage traits in Atlantic cod. To our knowledge, this is the first study that investigates the SGE of traits directly related to welfare in aquaculture species. The estimated ratio of total heritable variance over phenotypic variance (T2) was significantly greater than 1 for some of the fin damage traits, although the estimates had large standard errors. This means that we documented strongly significant SGE for fin damage traits but that the experiment was not large enough to accurately quantify the total heritable variance, although the experimental design was based on the simulation study by Ødegård and Olesen [18]. They showed that, over an average of 50 replicates, this design would provide accurate breeding values and estimates of direct and social genetic variance components. In addition, Ødegård and Olesen [18] did not fit the family effect (the effect due to common rearing ...

Why is That Spearfishing Fin So Huge? - SpearoscoutWhy is That Spearfishing Fin So Huge? - Spearoscout
Now, you have to think of what that means to your underwater performance in case of spearfishing. Since you have no oxygen, your moves need to count for more distance travelled, because on a moments notice you might need to get to the surface for a breath and you cant afford to move slowly, same thing if youre experiencing a blackout from lack of energy or from the waters pressure (yes, this happens.) Spearfishing is a dangerous sport that leaves no time for slow movement.. So, not only does it mean you propel faster, but it also means the total distance you propel is going to require less energy because of the blades unique build.. Scuba divers are advised to absolutely not dive with freediving fins because the longer and heavier fins will cost them more effort than their regular fins which will cause their legs to go sore over the long duration of their dive. Freedivers (and by extension, spearfishermen), however, are able to exert that effort and get a momentary break for their legs when ...
