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: Plans for an International Symposium on the Early Life History of Fish were first discussed in 1967 at the F. A. O. Advisory Committee on Marine Resources Research {A. C. M. R. R. }. It was considered that studies on fish eggs and larvae were of value in estimating the size of fish stocks, in appraising the stock-recruitment relationship, and in helping to answer questions on the systematics and taxonomy of fish. An A. C. M. R. R. Working Party recommended in 1969 that a Symposium should be held and after discussion with the International Associa tion of Biological Oceanography {I. A. B. O. } Dr. J. H. S. Blaxter of the Scottish Marine Biological Association {S. M. B. A. } agreed to con vene the meeting with the help of a steering committee. Various in ternational agencies were interested in the meeting and agreed to sponsor it in various ways. These agencies included F. A. O. , I. A. B. O. , the International Council for the Exploration of the Sea {I. C. E. S. } and the Scientific Committee for Oceanic Research {S. C. O. R. }. In the final event F. A. O. supported the meeting by publishing the abstracts beforehand, providing travel funds for participants and publishing a report after the meeting. I. A. B. O. and S. C. O.

Download or read book Environmental Factors Associated with the Spatial and Temporal Occurrence of Fish Eggs and Larvae During Pelagic Drift in Lower Green Bay, Wisconsin written by Marian Lynne Shaffer and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The survival of fishes in the early life stages is the primary determinant of future cohort strength, and the probability of survival is directly related to environmental conditions that change in time and space. The distribution of pelagic drifting fish eggs and larvae and the factors that drive them are largely unknown in Green Bay, Lake Michigan. In this study, two sampling methods were used to assess the influences of space, time, and environmental conditions on ichthyoplankton assemblages in Lower Green Bay and theFox River during summers 2014 and 2015. Ichthyoplankton samples were collected biweekly at the same 35 sites, and environmental data including dissolved oxygen, water temperature, pH, turbidity, and chlorophyll a were simultaneously collected at each site to characterize environmental conditions. A total of 36,935 larval fish and 65,531 eggs were collected in this study. Statistical analyses revealed that environmental factors influence variation in the abundance and distribution of fish eggs and larvae, specifically water temperature, pH, chlorophyll a, dissolved oxygen, and depth. However, space combined with environmental factors also contributed substantially to ichthyoplankton variability. Preferred spawning and nursery habitats combined with the effects of environmental forces were considered to be the major causes of spatial variation. Although best-fitting models did not include the effect of time, abundance of fish eggs and larvae showed temporal variation that was determined to be due to the reproductive strategy of adult fishes in Lower Green Bay and the Fox River.

This book was released on 2003 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The effects of food availability and water temperature on larval Pacific herring growth rates and survival were studied using a coupled biophysical model for 1993 through 1997. The herring growth model included feeding gains, metabolic costs, mortality losses and vertical migration of the herring larvae. In years when springtime oceanographic processes resulted in a high concentration of zooplankton, food availability did not limit larval herring growth rates; water temperature determined survival. However, in other years, food availability did limit survival, either due to insufficient food concentrations or to inaccessibility of the food. Vertical migration occasionally was restricted by strong water column stratification, which prevented the larvae from reaching food concentrations sufficient for growth. Thus the amount of food, the temperature, and the vertical distribution of the food and the larvae were found to affect growth. The study of vertical properties of factors affecting larval fish must be included in larval fish research"--Leaf iii.

Book excerpt: It is now clear that data based on the studies of fish eggs and larvae make a number of unique contributions to fishery science that are crucial for accurate assessment and management of fish populations, including those of commercially important fisheries. This valuable book demonstrates why fish eggs and larvae are important, how the characteristics of early life stages require a somewhat different research approach and how information on early life stages can be applied and interpreted to yield unique insights into fish populations. The editors of Fishery Science have drawn together an extremely useful and well-written book with contributions from internationally respected researchers from North America, Asia and Europe. Chapters include a discussion of the unique nature of early life stages, age and growth, mortality, recruitment, populations analysis, habitats, human impacts and management. A carefully selected set of case studies demonstrates several specific applications of early life history information to a number of fishery problems. Fishery Science was designed to complement existing textbooks and is an essential purchase for all fisheries students and professionals, and for biologists working on the early life stages of fish. This exciting book is also of great value to ecologists, marine, freshwater and environmental scientists, populations biologists and oceanographers. All libraries in universities and research establishments where biological and fishery science are studied and taught should have copies of this book available on their shelves.

This book was released on 1997-07-31 with total page 638 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.
