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. The.

Available in PDF, EPUB and Kindle. Book excerpt: This volume combines articles on shallow lakes from leading European scientists in limnology. It covers aspects of the dynamics of macrophytes, phytoplankton, zooplankton and benthos, nutrient loading, littoral-pelagic interactions, and sediment-water interactions, as well as lake management. The object was not to separate theory (e.g. modelling) and management in order to generate new theories for the understanding of shallow lake ecosystems. The volume provides a comprehensive overview of the ecology of shallow lakes, a lake type which differs in prominent ways from deeper lakes. The broad spectrum of issues may also reflect the spectrum of interested readers such as limnologists, water engineers, hydrobiologists, who will be informed on a high level about new developments.
Download or read book Early Life History and Recruitment in Fish Populations written by R.C. Chambers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the processes influencing recruitment to an adult fish population or entry into a fishery occur very early in life. The variations in life histories and behaviours of young fish and the selective processes operating on this variation ultimately determine the identities and abundance of survivors. This important volume brings together contributions from many of the world's leading researchers from the field of fish ecology. The book focuses on three major themes of pressing importance in the analysis of the role that the early life history of fishes plays in the number and quality of recruits: the selective processes at play in their early life history; the contributions of early life history to the understanding of recruitment.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth and survival of larval fish are influenced by a suite of biotic and abiotic factors. Because aquatic systems are characterized by strong heterogeneity in biotic and abiotic conditions along a vertical gradient, the vertical distribution of larval fish can profoundly affect their growth and survival. In large systems such as the Great Lakes, vertical distribution patterns can also influence dispersal and ultimately settlement events. Despite its importance during early life stages, little is known about vertical distribution patterns of larval fish in Lake Michigan. My objective was to describe the vertical distribution of the larval fish community in pelagic waters of Lake Michigan and determine which biotic and abiotic factors most strongly influence their vertical distribution. Additionally with controlled laboratory experiments I sought to determine how two of these factors (light intensity and prey density) influence the foraging success of a fish species with a pelagic larval stage, yellow perch (Perca flavescens). To determine vertical distribution, the upper 27 meters of the water column was divided into six discrete depth bins where larval fish and zooplankton were collected, in addition to recording light intensity, and temperature. Larval fish from 5 species were collected during the study: alewife (Alosa pseudoharengus), bloater (Coregonus hoyi), burbot (Lota lota), deepwater sculpin (Myoxocephalus thompsonii), and yellow perch (Perca flavecens). Among the five species, I observed three general patterns of larval distribution. Alewife and yellow perch larvae were restricted to the epilimnion, deepwater sculpin were restricted to the hypolimnion, and bloater and burbot were collected throughout the upper 27 m of the water column, and exhibited diel differences in distribution patterns. My analysis elucidates the importance of abiotic over biotic factors in the structuring of larval fish vertical distribution in Lake Michigan, as temperature was shown to influence the distribution of most species, while density of crustacean zooplankton did not. The inter-specific differences of vertical distribution observed among the 5 species collected have important consequences for dispersal, settlement, and recruitment variability. In the laboratory I examined the influence of light intensity on foraging success and prey selection of larval yellow perch at both high (150 zooplankton/L) and low (25 zooplankton/L) prey densities, with a mixture of zooplankton taxa common to lakes containing yellow perch. In addition to light intensity and prey density, the effect of ontogeny of yellow perch larvae was examined by using fish ranging from 9 to 15 mm. The results of my study indicated that larval yellow perch are well adapted to feed at a wide range of light intensities, as there was no difference in foraging success between light intensities ranging from 0.1 to 60 ℗æmol s-1 m-2 PAR. Increasing prey density from 25 to 150 (zooplankton/L) significantly improved the foraging success of larval yellow perch. However, the influence of prey density on foraging success of larval yellow perch was dependent on fish length, with improved foraging success with increased prey density occurring only for larger larvae. Overall, prey selection by larval fish was influenced by light intensity, prey density, and fish length, but the set factors which influenced selection for specific prey types differed. The results of this study combined with evidence from other field and laboratory work, highlight the need for a better understanding of the influence of prey density on foraging success throughout ontogeny.
