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: "Yellow Perch Perca flavescens are important as forage for other species and for sport fishing in many northern lakes. However, estimating post-larval Yellow Perch populations can be difficult because of many environmental factors that cause unexplained variation. The objective of this study was to help reduce unexplained variation by determining a post-larval Yellow Perch population density estimate on Blackduck Lake, MN, provide guidance to help dete1mine the number of trawls required for trawling-based recruitment indices to achieve varying levels of precision, and test for the effects of wind speed and direction on post-larval Yellow Perch spatial variability. This study estimated a density of 0.45 fish/m3 (0.58 SD) during the sampling period (26 Jun - 07 Jul 2017). It was determined that between 10-15 trawls produced a precise density estimate; however, trawls should be taken over multiple days in varying wind speeds to avoid over/under estimation. Trawling should also be performed in-line with wind direction to ensure non-bias estimates are calculated from both upwind and downwind sectors. This study determined wind speed and direction had a significant influence on the distribution of post-larval Yellow Perch, as more fish were caught in the downwind sector until winds reached 15 kmph. At 15 kmph, fish densities were equal in the upwind and downwind sectors of the lake. Wind did not have a significant influence though on how post-larval Yellow Perch were distributed by total length. During high wind events, more fish were found in the upwind sector of the lake, suggesting that post¬larval fish are being moved laterally out of non-towable areas. From the results of this study it appears Yellow Perch must continually relocate back into shallow areas after each high wind event moves them out of the non-towable areas, until they are strong enough to resist the wind."-Abstract.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. 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.

Hopky and published by . This book was released on 1982 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake trophy and fish population characteristics were studied in two small saline lakes in southwestern Manitoba during the 1978 and 1979 open-water periods. Greater eutrophy in St. Dalmas Lake (area = 61.3 ha; T.D.S. = 2183 mg.1 -1) compared to S. Thomas Lake (area = 79.2 ha; T.D.S. = 1390 mg.1 -l) was related to highly localized edaphic conditions. A higher mean annual chlorophyll-a concentration and zooplankton biomass was observed in St. Dalmas. Consistent with lake trophic differences, the pooled abundance or biomass of the principal fish species in St. Dalmas (yellow perch Perca flavescens, and walleye Stizostedion vitreum vitreum) was greater than that of those in S. Thomas (northern pike Esox lucius, yellow perch and walleye). Perch predominated in both lakes, but their relative abundance and biomass was greater in St. Dalmas. Mark and recapture experiments showed greater walleye biomass (10.7 kg/ha) in St. Dalmas than the biomass of either S. Thomas walleye (0.9 kg/ha) or pike (5.5 kg/ha). These estimates are comparable to mean values reported for non-saline lake populations. A more diverse piscine community was observed in S. Thomas...
