Book excerpt: Variability in annual recruitment for many fishes is correlated with survival during the larval phase. Yellow perch in Lake Michigan have experienced sustained recruitment failure since 1990 and this has been blamed on low larval survival. Direct examination of factors important to larval yellow perch survival in Lake Michigan is complicated by the large size of the lake (52,000 km2) and the short length of the pelagic larval period (30-40 days). Individual-based modeling is a valuable indirect method for assessing the importance of multiple factors to larval survival. I used an individual-based modeling approach combined with field data collection to test four hypotheses regarding factors limiting survival of larval yellow perch in Lake Michigan. I tested whether larval survival is limited by prey community composition, size-selective predation, advection of larvae into offshore habitat or an interaction of these factors. I sampled larval and zooplankton abundance in Lake Michigan along a transect from 1 - 32 km from shore in 2000 and 2001. I conducted laboratory experiments to quantify larval vulnerability to predation by three typical predators as a function of both predator and prey size. I also conducted laboratory experiments to quantify larval selectivity for different zooplankton prey as a function of larval size and prey community composition. I used the results of these experiments to develop an individual-based model specifically to describe growth and survival of larval yellow perch. Field data suggest that larval yellow perch are being transported from the nearshore to the offshore zone of Lake Michigan, but the timing of this transport varies between years. Model simulations in which the offshore prey community and the timing of larval advection were both varied suggested that larval survival will be highest in years when advection occurs within two weeks of peak hatch, allowing larvae to exploit offshore prey resources early during ontogeny.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Limited experience with live food regimes and fragmentary knowledge of nutritional requirements have been inhibitors for the indoor-intensive production of Yellow Perch Perca flavescens larvae. Live food enrichment with polyunsaturated fatty acids (PUFA) is a proven means of increasing the growth and survival of larval fish, but no studies to date have tested this method on Yellow Perch. This thesis consists of two live food enrichment experiments carried out in May/June of 2013 and 2014, as well as lipid analysis of live food and fish samples from both years. The 2013 study examined the effect of live food enrichment with docosahexaenoic acid (DHA; C22:6[n-3]) and arachidonic acid (ARA; C20:4[n-6]) on the growth, survival, and swim bladder inflation of larval Yellow Perch. The 2014 experiment was similar in design, but compared PUFA enrichments in ethyl ester (EE) and triglyceride (TG) forms. Both experiments were conducted in two phases. The first phase was carried out in a recirculating system with nine 50 L conical tanks, initially stocked at 50-70 larvae/L. Live rotifers Brachionus plicatilis were provided to larvae for the first two days of exogenous feeding, before transitioning to Artemia franciscana nauplii for the remaining eight days of this phase. The second phase was carried out in nine 60 L cylindrical flow-through tanks, initially stocked with 10 larvae/L. During this phase, fish were fed Artemia nauplii for 3 days, then gradually transitioned to a formulated starter diet (Otohime A®) over a 7 day period. At the end of the first phase the ARA and DHA enriched groups had significantly (p=0.05) improved swim bladder inflation rates when compared to the control group. For the second phase, enriched groups had significantly larger mean weights and growth rates than the control. The EE-TG experiment was similar in design to the DHA-ARA experiment, except that the second phase was concluded after seven days of feeding. At the end of the first phase, the EE group had a significantly improved average weight and growth rate than the TG group. No significant trends were seen in the second phase. Following enrichment experiments, the fatty acid composition of live feeds and experimental fish were analyzed using the gas chromatography method. Fatty acid composition of zooplankton was heavily influenced by enrichments, and composition of larvae/juveniles generally reflects that of their live prey. Arachidonic acid was assimilated poorly in ARA enriched Artemia, but DHA was found in abundance. Also, rotifers tended to assimilate PUFA better in EE form, while Artemia achieved higher PUFA contents with TG enrichments. The data support that PUFA enrichment of live food can be utilized to increase the success of Yellow Perch culture by increasing growth and swim bladder inflation rates during the critical period of larval development.

This book was released on 2021-11-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walleye, one of the most sought-after species of freshwater sport fishes in North America, has demonstrated appreciable declines in their numbers from their original populations since the beginning of the 20th century. Similarly, Yellow Perch, once the most commonly caught sport fish and an important commercial species in North America, have also shown declines. Compiling up-to-date information on the biology and management of Walleye, Sauger, and Yellow Perch, including research on systematics, genetics, physiology, ecology, movement, population dynamics, culture, recent case histories, and management practices, will be of interest to managers, researchers, and students who deal with these important species, particularly in light of habitat alterations, population shifts, and other biotic and abiotic factors related to a changing climate.

Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.
