Book Synopsis Food of Alewives, Yellow Perch, Spottail Shiners, Trout-perch, and Slimy and Fourhorn Sculpins in Southeastern Lake Michigan by : LaRue Wells
Download or read book Food of Alewives, Yellow Perch, Spottail Shiners, Trout-perch, and Slimy and Fourhorn Sculpins in Southeastern Lake Michigan written by LaRue Wells and published by . This book was released on 1980 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stomachs of 1,064 alewives, 1,103 yellow perch, 246 spottail shiners, 288 trout-perch, 454 slimy sculpins, and 562 fourhorn sculpins from Lake Michigan were examined for food contents. Fish were sampled primarily from March to November and nearly all were caught at the bottom in the southeastern part of the lake near Saugatuck, Michigan. Pontoporeia was the most commonly reprented food item in the stomach contents of the fish examined, with immature midges, Mysis (a type of freshwater shrimp), copepods, cladocerans, fingernail clams and crayfish also being represented. Different species consumed different proportions of foods. Zooplankton was the principle food of alewives and spottail shiners, but was also consumed in small quantities by yellow perch and trout perch. Mysis was important to fourhorn sculpins, in addition to Pontoporeia. Immature midges were a major portion of spottail shiners and trout perch, also being consumed by alewives. Fish were often the most important food of yellow perch in the largest size category. Crayfish were a sizable portion of the diet of yellow perch on rocky bottoms, but sparingly on smooth bottoms. Spottail shiners also ate substantial numbers of fingernail clams.

Book Synopsis Lipids in Freshwater Ecosystems by : Michael T. Arts
Download or read book Lipids in Freshwater Ecosystems written by Michael T. Arts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental purpose of this book is to synthesise the divergent literature on aquatic lipids into a co-ordinated, digestible form. A large part of the book addresses lipid composition and production in freshwater organisms, with chapters on phytoplankton, zooplankton and benthic invertebrates. A common theme throughout the book is the function of lipids in aquatic food webs, with a chapter devoted exclusively to lipids as indicators of health in fish populations. A complementary chapter highlights the role of lipids and essential fatty acids in mariculture. Methodologies to determine the lipid content of aquatic samples and suggestions as to the utility of fatty acids as trophic markers are included, as is one chapter on the role of lipids in the bioaccumulation and bioconcentration of toxicants and another on the relationships between lipids and surface films and foams. The final chapter highlights the similarities and differences between lipids of marine and freshwater origin. Students and researchers in ecology, phycology, aquatic toxicology, physiological ecology and limnology will find this an invaluable guide and reference.
Book Synopsis Contemporary Studies on Fish Feeding by : Charles A. Simenstad
Download or read book Contemporary Studies on Fish Feeding written by Charles A. Simenstad and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: GUTSHOP '84 was the fourth in a series of workshops on various aspects of fish feeding (Table 1). Initially, the organizers merely invited regional (Pacific Northwest) fisheries scientists to share, and possibly develop mutual solutions to, the many technical problems associated with trying to obtain meaningful, quantitative information from fish stomach contents, and the subsequent statistical treatment and interpretation of the multivariate data. Since then, although not explicitly based upon any internal cycle, these scientists and increasingly more and more dispersed colleagues continued to congregate for workshop deliberations every two or three years. From the 49 attendees at the first workshop, the number of participants had grown to 65 at GUTSHOP '78, and 107 at GUTSHOP '81. By the third workshop, we were drawing scientists from across the U. S. and Canada, and from as far away as Norway. The topical content of the workshops has also evolved from the predominantly technical aspects of fish collection and stomach contents processing techniques, statistical analysis, and data manipulation and presentation to considerations of theoretical ecology, bioenergetics, and behavior.

Geographical abundance varied and were partly attributable to differences in fishing mortality.
