Growth and development of Argulus coregoni (Crustacea: Branchiura) on salmonid and cyprinid hosts. (1/7)

The obligate fish ectoparasite Argulus coregoni is strictly specific to salmonids and is very rarely found on other fish species. The ability of the parasite to grow and complete its life cycle on a cyprinid host, Rutilus rutilus, was compared with that on a typical salmonid host, Oncorhynchus mykiss. Rearing experiments were run for 42 d with newly hatched metanauplii in flow-through tanks. Body length and sex of the parasites were recorded every 5 d. Growth rates on O. mykiss exceeded those on R. rutilus from the age of 2 wk, at which time the parasites reached a length of about 3.5 mm. Males grew faster than females at the beginning of the experiment up to a length of 2.5 to 3.0 mm; thereafter, a faster growth rate was observed in females. In another experiment, association of parasites with the hosts was monitored and residence time defined as the period between attachment and first detachment from the host. Longer residence time was observed on O. mykiss than on R. rutilus; female parasites stayed on both fish species longer than did males. Faster growth of parasites could be associated with longer uninterrupted periods of attachment to hosts, since frequent detachment means higher energy losses and less time available for feeding. Despite its slower growth on R. rutilus, A. coregoni matured and laid egg clutches, but took 5 d longer than on O. mykiss. The potential of A. coregoni to complete its life cycle on cyprinids could have important ecological consequences, creating an infection reservoir when the main salmonid hosts are rare or temporarily missing.  (+info)

Efficacy of emamectin benzoate in the control of Argulus coregoni (Crustacea: Branchiura) on rainbow trout Oncorhynchus mykiss. (2/7)

Efficacy of in-feed treatment with emamectin benzoate (Slice) for the control of ectoparasitic Argulus coregoni on rainbow trout Oncorhynchus mykiss was tested under laboratory and field conditions. In both experiments fish were fed with fish feed to deliver a therapeutic dose of 0 (control) or 50 microg emamectin benzoate kg(-1) d(-1) (treatment) for a period of 7 d. After 3 d of challenge with A. coregoni in the laboratory, the infestation level in treated fish was lower than that observed in the controls (p < 0.001). Efficacy of 100% against newly hatched A. coregoni metanauplii and adults and 80% against juveniles was observed. In the field, trial medication was undertaken at 2 sections on a flow-through canal with 1 wk between treatments. Mean infestations of 100 to 200 A. coregoni per fish with 100% prevalence was recorded prior to medication. Following the treatment, the mean infestation of A. coregoni on fish declined to 31 lice per fish at Section A and 2.5 lice per fish at Section B. Then, after 28 d of treatment, the number of lice per fish was < 1 at Section A; in contrast the mean number of A. coregoni per fish at the control section was > 20. The prevalence of A. coregoni remained < 50% over a period of 72 d of treatment, but started to increase again thereafter. This suggests that emamectin benzoate concentration in fish remained at a level high enough to kill A. coregoni over a period of 9 wk. Emamectin benzoate was very effective in the control of A. coregoni infesting trout.  (+info)

Seasonal and vertical patterns of egg-laying by the freshwater fish louse Argulus foliaceus (Crustacea: Branchiura). (3/7)

Argulus foliaceus is a damaging fish ectoparasite for which new control measures are being developed based on egg-removal. In an attempt to develop further understanding of seasonal and vertical egg-laying patterns in this parasite, egg-laying activity was monitored over the period 14 April to 17 November 2003 in 2 rainbow trout Oncorhynchus mykiss fisheries in Northern Ireland, UK. At Site 1, egg-laying was continuous from 21 April to 17 November, when water temperature was above 8 to 10 degrees C. At Site 2, egg-laying was continuous from 4 June to 29 October. In the early months of the season, egg-laying was recorded mainly within the top 1 m of the water column; however, a significant shift to deep water egg-laying was recorded between 7 July and 17 November at Site 1 and between 20 August and 29 October at Site 2. Egg clutches were preferentially laid at depths of up to 8.5 m during this time (Site 2), a feature of egg-laying hitherto unappreciated. Temperature and dissolved oxygen did not differ significantly among depths, but there was an increase in water clarity over time. However, the precise environmental triggers for deep water egg-laying are still unclear. These new insights into the reproductive behaviour of this species will be useful in developing control methods based on egg-removal.  (+info)

Five ectoparasites from Turkish fish. (4/7)

Five ectoparasites were collected during the period of 2002-2005 from fish of Mediterranean Sea, Aegean Sea and inland waters of Turkey: Four crustaceans [Ergasilus mosulensis and Pennella instructa (Copepoda), Ceratothoa steindachneri (Isopoda) and Argulus foliaceus (Branchiura)] and one Annelida (Piscicola geometra) were found. The species, E. mosulensis, P. instructa and C. steindachneri have been reported for first time in Turkish waters, and A. foliaceus and P. geometra for the time from the Cavuscu Lake.  (+info)

Fish lice species vary in size from just a few millimetres to over 30 millimetres (1.2 in) long, with females usually somewhat larger than the males. There are many species and they are present throughout the world, some having been introduced to the west from Asia with consignments of fancy fish in the early 20th century.. Almost all species in the family are external parasites of fish, with a few species that parasitise on invertebrates or amphibians. They have a wide flattened, oval body, almost entirely covered by a carapace. Their compound eyes are prominent, and the mouth and the first pair of antennae are modified to form a hooked, spiny proboscis (stylet) equipped with suckers, as an adaptation to parasitic life. They have four pairs of thoracic appendages, which are used to swim when they release from the fish. They leave the host for up to three weeks in order to mate and lay eggs. The eggs are laid in strings and patches of jelly on stones and hatch into parasitic larvae.. Affected ...

We have investigated the influence of cortisol on the beta-adrenoreceptor population of rainbow trout [Oncorhynchus mykiss (Walbaum)] erythrocytes and determined what impact it has on the adrenergic responsiveness of erythrocytes in vitro to exogenous catecholamines. To do so, the erythrocyte beta-adrenoreceptors were characterized in fish with chronically elevated plasma cortisol levels (118 +/− 5.9 ng ml-1, greater than 10 days) and compared with shams, using radioreceptor assay techniques. The number of internalized, low-affinity receptors was increased when cortisol levels were raised, but the number of high-affinity, surface receptors was not altered. The physiological significance of this response was ascertained by assessing the in vitro sensitivity (or responsiveness) of erythrocytes to adrenaline and noradrenaline (10-1000 nmol l-1) under normoxic (PO2 = 16.13 +/− 0.55 kPa, PCO2 = 0.41 +/− 0.01 kPa) or hypoxic (PO2 = 4.13 +/− 0.15 kPa, PCO2 = 0.43 +/− 0.01 kPa) conditions. ...
The freshwater fish louse Dolops carvalhoi is an ectoparasite of pacu, Piaractus mesopotamicus capable of causing substantial damage to its hosts. The aim of this study was to investigate some aspects of the host-parasite interaction between these two species. For this purpose the physiological and morphological responses and the participation of the non-adaptive immune system of pacu to the experimental infestation with D. carvalhoi were analyzed. Three different experimental protocols were designed in order to find out the effects of the parasites on their hosts, the host responses that may interfere with parasite establishment and the influence of chronic exposure of hosts with juvenile D. carvalhoi to a second acute stressor of confinement. The results showed that even low level of adult parasite infestation is capable to induce a stress response in the hosts. No changes were observed regarding the plasma osmoregulatory parameters, while an increased number of gill chloride cells and ...

2004. 26cm. Pp.240. 20 photos & figures. Hardbound.Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young.Leeches, Lice and Lampreys explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals. The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the host s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone

Till the moment of hatching there appear successively two dorsal organs and two cuticles. The first dorsal organ, stripelike, stretches along the dorsal region of the embryo. After it disappears there remains, instead, in the first cuticle as long a seam or suture. But before it has disappeared out of its hind end, arises the second dorsal organ. This one produces a sticky substance, which comes to spread over the second cuticle, especially in the dorsal region of the embryo. At the moment of hatching this cuticle, including the embryo, swelling up as a vesicle, serves as an active mechanism to split the covering along the seam mentioned above, and to open widely the resulting valves. Such a mode of hatching, with the dorsal organs contributing to it, seems to be nothing else than a modified moulting adapted to the moment of hatching.. ...
This manual has a long history that started many years ago at the University of Comahue in North Patagonia (Argentina), when some of us were involved in education and training during the early days of trout farming. We considered a comprehensive fish dissection manual, with relevant additional information, was missing and started to focus on rainbow trout. Using the limited resources provided initially by the university, our first pictures were taken with a heavy camera using photographic films, something many of the younger readers probably have never seen: those cellulose strips requiring a lengthy developing process before pictures could be seen at all!. Despite the enthusiasm it soon became obvious that publishing a book with many colour pictures and on a discipline at the time far from popular or highly demanded outside the academic world, was going to be financially very costly. Then time and availability and our evolving professional pathways meant the project was put to sleep for ...

This study was conducted to evaluate the potential pathogenicity of the bacterium Flavobacterium columnare on rainbow trout Oncorhynchus mykiss eyed eggs. Survival to hatching was unaffected by the inclusion in the incubation water of either 300 colony-forming units (CFU) ml−1 or 3000 CFU ml−1 of F. columnare at either 10 or 12° C in either McConaughy or Shasta strain eyed eggs. Bacterial numbers, obtained via scanning electron microscopy or culture, and external membrane morphology were also not significantly different among eggs receiving different concentrations of F. columnare. Initial F. columnare burdens were significantly and positively correlated to the presence of biofilm on the egg external membrane, and biofilm was in turn significantly correlated with increased membrane degradation. The use of either streptomycin or tetracyclin antibiotics significantly reduced bacterial numbers on McConaughy strain eggs, and more eggs survived to hatch in those dishes treated with antibiotics ...

Although it is still present in aquatic ecosystems, oxidative stress driven by TBT has been still poorly investigated in fish. The aim of the study was to examine the time-course stress responses in liver of rainbow trout that received a single intraperitoneal injection of tributyltin chloride (TBTC) or tributyltin ethoxide (TBTE), both at a dose of 0.05 and 0.5 mg/kg. Levels of metallothioneins, total glutathione, malondialdehyde, superoxide dismutase, catalase, glutathione peroxidase and glutathione S-transferase were evaluated at 3 and 6 days post-injection. Tin load was measured in the muscle of the same fish. Differences were observed in the time-course accumulation of tin with a clear dose-response relationship. Although individual oxidative stress biomarkers varied, the biomarker ...
Maxillopoda. Ostracoda. Malacostraca. Crustaceans (Crustacea) form a very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. The 50,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 12.5 ft (3.8 m) and a mass of 44 lb (20 kg). Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates by the possession of biramous (two-parted) limbs, and by the nauplius form of the larvae.. Most crustaceans are free-living aquatic animals, but some are terrestrial (e.g. woodlice), some are parasitic (e.g. fish lice, tongue worms) and some are sessile (e.g. barnacles). The group has an extensive fossil record, reaching back to the Cambrian, and includes living fossils such as Triops cancriformis, which ...
