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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Researchers, instructors, and students will appreciate this compilation of detailed information on the crustacean zooplankton of the Great Lakes. The authors have gathered data from more than three hundred sources and organized into a useful laboratory manual. The taxonomic keys are easy to use, suitable for both classroom and laboratory identifications. Detailed line drawings are provided to help confirm the identification of the major species. Zoologists, limnologists, hydrobiologists, fish ecologists, and those who study or monitor water quality will welcome this dependable new identification tool. A concise summary of pertinent information on the ecology of these zooplankton is provided in the main body of the text. A check-list of all species reported from each of the Great Lakes and notes on the distribution and abundance of more than a hundred species were compiled from an extensive search of existing literature. In addition, the authors collected samples from several locations on Lake Superior, in order to provide information on the abundance and life histories of the major crustacean species.

This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Third International Symposium on Cladocera, papers from which make up this volume, covered recent findings on the behaviour, life history, population genetics, reproduction, chemical communication, predator-prey interactions, epibionts, taxonomy, phylogeny, palaeolimnology and biogeography of this animal group. The Cladocera occupy an intermediate position in lake ecosystems, both as plankton and benthic organisms. Their often high abundance and their function, as transfer organisms from algae and dead organic matter to macro-invertebrates and fish, make them one of the most important organisms to affect the biological processes in freshwater ecosystems. The Cladocera living among the plankton often have recognizable distribution patterns and migrations; their size and brief life cycles make them popular in laboratory experiments; their cyclic parthenogenesis makes them suitable for many aspects of population genetics; and they are present as microfossils in lake sediments. All these features confer a unique status on the Cladocera as model organisms in many aspects of modern systematics and ecology.

Available in PDF, EPUB and Kindle. Book excerpt: There is a strong tendency now for specialists in various groups of organisms, or in various processes and their consequences, to get together at more or less regular intervals to discuss their subjects. This has hap pened e. g. with the Chironomidae, Ephemeroptera, and Plecoptera among the aquatic insects, and the Rotifera, Copepoda, and Ostracoda among the zooplankton. Finally the scientists working with the Cladocera, who have been isolated from one another for a long time except on a personal basis, have decided to do the same, largely through the initiative and drive of L. Forro. Thus, the First International Symposium on Cladocera was held in Budapest on 12-16 August 1985. Most of the roughly 60 attendees were from Euro pean countries, although a fair number came from Australia, Canada, India, Nigeria, and the United States. The accompanying table presents a list of attendees by country of origin. Regrettably, a number of persons who had expressed interest in coming were unable to do so.
