  • species
  • Prior to the publication of this book, the larval stages of only a small number of temperate Australian fish species were described. (australianmuseum.net.au)
  • Angie is investigating how the resulting hydrographic changes after the Bonnet Carré diversion and hypoxic zones affect important survival factors such as diet, growth, and condition in larval fish species. (gulfresearchinitiative.org)
  • However, assessment of heart function-especially if stroke volume is the focus of the study-should consider larval heart shape, with different models being applied on a species-by-species and developmental stage-by-stage basis for best estimation of cardiac output. (frontiersin.org)
  • For our data, the best single descriptor provided a classification accuracy of 77-95% and detection accuracy of 88-98%, depending on fish species and size. (biologists.org)
  • Such adaptations are important, researchers at the University of Illinois atUrbana-Champaign say, because the larval fish of at least two species of notothenioids that inhabit the Ross Sea at McMurdo Sound and Terra Nova Bay surprisingly lack sufficient antifreeze to protect them through their first three months of life. (bio-medicine.org)
  • We conclude that a combination of wind forcing, residual bottom inflow, and selective tidal stream transport are responsible for the ingress of larval fishes into Chesapeake Bay, and that the relative importance of the 3 mechanisms differs among species and changes with larval development. (odu.edu)
  • My focus at present is on a few large families that account for about a third of all reef fishes in the region: the gobies with about 150 species, the serranids with about 100 species, the labrisomids with about 50 species, and the chaenopsids with another 50 species. (coralreeffish.com)
  • Virtually all of the thousands of species of tropical reef fishes have a larval stage that spends weeks to months in the open ocean before returning to the reef to settle. (coralreeffish.com)
  • Jeff Leis at the Australian Museum (also now at the Institute for Marine and Antarctic Research of the University of Tasmania ) has published his opus (or opuses) with comprehensive coverage of the Indo-Pacific species of reef and shore fishes. (coralreeffish.com)
  • Using estimates of PLD obtained from species of North American darters (Percidae: Etheostomatinae), we demonstrate that this freshwater fish clade exhibits surprising variation in PLD. (royalsocietypublishing.org)
  • Darters are a clade containing approximately 200-250 species of North American stream-dwelling fishes that exploit habitat gradients ranging from steep headwater mountain streams to slow-moving coastal bayous [ 9 , 10 ]. (royalsocietypublishing.org)
  • Here, we compare gene flow patterns of 7 littoral fish species from 6 families with a range of early-life-history traits sampled at the same geographic locations across common environmental discontinuities in the form of oceanic fronts in the Western Mediterranean. (pnas.org)
  • We show that these fronts represent major barriers to gene flow and have a strong influence on the population genetic structure of some fish species. (pnas.org)
  • Thus, the general hypothesis that oceanic fronts may act as a barrier to dispersal for most littoral fish species irrespective of their early-life-history traits remains largely untested. (pnas.org)
  • teleost fish
  • In the present study, we show that future predictions of ocean warming (+4°C) and acidification (ΔpH=0.5 units) may compromise the development of early life stages of a highly commercial teleost fish, Solea senegalensis . (biologists.org)
  • duration
  • For each year (1993 excluded), 150 settling individuals were selected and used for reconstruction of larval stage duration based on otolith daily ring counts. (uib.no)
  • Mean larval stage duration varied between about 40 and 60 d, without any clear significant pattern between or within years. (uib.no)
  • Year-class strength of plaice in the western Wadden Sea was not related to mean larval stage duration. (uib.no)
  • Mean larval stage duration did not show a clear pattern during the period of immigration, nor with reconstructed temperature conditions. (uib.no)
  • The observed decrease of larval stage duration with temperature in the field was lower than that observed under laboratory conditions, suggesting food limitation with increasing temperature during drift. (uib.no)
  • growth
  • Angie Hoover wants to know how large freshwater pulses and other environmental stressors affect the diet, growth, and condition of larval fishes. (gulfresearchinitiative.org)
  • To test the effects of diatom production on larval fish growth and condition, laboratory experiments were performed with larval North Sea cod reared on different algal food chains. (oup.com)
  • Results indicate that larval growth rates are significantly influenced by the content of essential fatty acids of the algal food source: growth rates were positively correlated with the content of DHA (C22:6ω3) and negatively with EPA (C20:5ω3). (oup.com)
  • Regressions of growth rates against EPA and DHA content indicated no inhibitory effect of diatom production on growth in larval cod. (oup.com)
  • This study analysed the effects of a parasitic copepod on the larval growth of the Chilean triplefin Helcogrammoides chilensis (Tripterygiidae) based on the microstructure of the sagittal otoliths. (springer.com)
  • Spawning
  • Managers should consider that oceanographic distances describing the direction and intensity of currents during the spawning period are significant predictors of larval connectivity between sites, as opposed to geographic distances. (springer.com)
  • coral reef
  • Understanding this early-life-history process is clearly important to understanding the population dynamics and, more broadly, the biogeography, ecology, and evolution of coral reef fishes. (coralreeffish.com)
  • algae
  • Indoors, artemia and rotifers, which are fairly easy to raise, are used as carriers for delivering algae and enrichments to larval fish and shrimp. (reeffrontiers.com)
  • patterns
  • The larval mesopelagic fish assemblage and its distribution patterns were investigated in the Kuroshio region off southern Japan in late winter. (mendeley.com)
  • Although a number of studies conclude that selective tidal stream transport is the mechanism responsible for larval ingress, few studies consider alternative mechanisms or consider passive explanations for tidal patterns in larval distributions. (odu.edu)
  • We found little evidence for the hypothesis that tidal patterns in larval distributions resulted from passive processes (water mass-specific distributions, buoyancy, vertical mixing), thereby supporting the hypothesis that tidal patterns resulted from active behaviors. (odu.edu)
  • freshwater fish
  • The Fish Ecology Collaborative Research Unit (FECRU) aims to foster rigorous science in freshwater fish ecology in Australia, and more specifically the Murray-Darling Basin. (edu.au)
  • However, human activity is precipitating a global wave of extinction, and we used the freshwater fish group known as darters (Percidae: Etheostomatinae) to take advantage of this anthropogenic 'experiment' to comparatively examine the causes and consequences of evolutionary divergence in PLD. (royalsocietypublishing.org)
  • This could be why freshwater fish often have a short or completely lack a pelagic larval stage [ 1 , 8 ]. (royalsocietypublishing.org)
  • behaviour
  • Drosophila oviposition behaviour and larval development creates patches containing suitable hosts during several successive days. (brillonline.com)
  • coastal
  • This specific trip goes from Boston to Casco Bay and back, and is focused on collecting water samples to help establish nutrient limits (the maximum quantities of nitrates and phosphates in the water that will still allow healthy animal and plant life and clean water for fishing, kayaking, and other uses) for coastal waters. (wellsreserve.org)
  • eggs
  • Copepod eggs were collected, hatched, and the N1 nauplii (200l −1 ) were fed to post-yolk-sac larval cod. (oup.com)
  • distinct
  • We showed that in the GC, the strong asymmetry in the oceanic currents causes larval connectivity to show different values when measured in distinct directions (anisotropy). (springer.com)

  • diets
  • Emulsified dried diets can also be used, but they should not be added directly to the larval rearing tank, as they can foul the water. (reeffrontiers.com)
  • She identified and counted the gut contents to determine the fish's diets and weighed and measured the fish to determine each organism's condition. (gulfresearchinitiative.org)

  • It is establishing partnerships with government natural resource agencies interested in the management, conservation or restoration of fish populations and the ecosystems they occupy and other research centres such as the Murray Darling Freshwater Research Centre. (edu.au)
  • behavior
  • We propose that eye convergence represents the engagement of a predatory mode of behavior in larval fish and serves to increase the region of binocular visual space to enable stereoscopic targeting of prey. (frontiersin.org)
  • time
  • The unexpected discovery, reported online by the Journal of Experimental Biology ahead of regular publication, counters the assumption that these vital proteins must be present from the time of hatching -- a view held by scientists since fish AFPs were found in the 1960s. (bio-medicine.org)
  • This will help to ensure that fish are free from disease and suffering whilst at the same time promote good productivity and comply with legislation. (thefishsite.com)
  • It's been 7 years since we started collecting larval fish and 3 years since our last update (See Team Larval Fish at the Wells Reserve ) so it's time for another look at the wonderful world of larval fish! (wellsreserve.org)
