This book was released on 1999 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 12-week feeding trial was conducted in aquaria with juvenile (36.0±1.2g) largemouth bass (Micropterus salmoides) to examine the effects of dietary supplementation of methionine, lysine, and long-chain polyunsaturated fatty acids on growth, feed conversion and body composition. Diets were formulated to increase dietary concentrations of methionine, lysine, and polyunsaturated fatty acids (PUFA) to match levels found in whole body samples of largemouth bass in previous research. All diets were formulated to be isonitrogenous (47% protein) and isocaloric (2.7 kcal digestible energy g −1). The control diet was formulated similar to diets previously tested for largemouth bass. Diets 2 and 3 were similar to the control diet but were supplemented with 2% lysine and 1% methionine, respectively. Diet 4 was formulated to increase long-chain polyunsaturated fatty acids, especially docosohexanoic acid (DHA) (22:6 u-3), by replacing menhaden fish oil with squid oil. Fish were fed all they would consume in 10 minutes, twice daily. At harvest, there were no statistically significant differences (P>0.05) in average individual weight or specific growth rate (SGR) among fish fed the four diets. The feed conversion ratio (FCR) of largemouth bass fed the diet supplemented with methionine (1.7) was significantly lower (P

Download or read book Nutrition and Feeding of Fish written by Tom Lovell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture is now recognized as a viable and profitable enterprise worldwide. As aquaculture technology has evolved, the push toward higher yields and faster growth has involved the enhancement or replacement of natural foods with prepared diets. In many aquaculture operations today, feed accounts for more than one-half the variable operating cost. Therefore, knowledge of nutrition and practical feeding of fish is essential to successful aquaculture. This book is not written exclusively for scientists but also for students, practicing nutritionists, and aquaculturists. It covers the known nutrient requirements and deficiency effects for different fishes, and digestion and metabolism of nutrients and energy. It discusses nutrient sources and preparation of practical and research feeds. It gives directions for conducting fish nutrition and feeding experiments. Feeding practices for salmonids, channel catfish, tilapias, shrimps and hybrid striped bass are presented. Since the first edition of this book was printed, the National Research Council of the National Academy of Sciences has revised the nutrient requirements for fish. These revisions are in the present edition. Other additions to this revised edition are chapters on nutrition and fish health, and bioavailability of nutrients. Each original chapter has been meticulously revised and updated with new information. Aquaculture is a dynamic area and new technologies are being introduced continuously; therefore, some of the material discussed in this revised edition may become obsolete quickly. Nonetheless, the material presented has been thoughtfully selected and updated to make it of maximum use to persons whose interests range from general aquaculture to animal nutrition to feed manufacture.

Download or read book Food Intake in Fish written by Dominic Houlihan and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intake of food by fishes is an area of study that is of great importance to the applied sciences of fisheries and aquaculture for a number of reasons. For example a thorough knowledge of factors influencing the ingestion of feed can lead to successful manipulation of the rearing environment of cultured fishes, thereby ensuring improved growth performance and feed utilisation, and decreasing the amount of waste (and consequent pollution) per unit of fish produced. This important book, which has arisen out of a European Union COST programme, illustrates how insights into the biological and environmental factors that underlie the feeding responses of fish may be used to address practical issues of feed management. Food Intake in Fish contains carefully edited contributions from internationally recognised scientists, providing a book that is an invaluable tool and reference to all those involved in aquaculture, especially those working in the aquaculture feed industry and scientific personnel in commercial and research aquaculture facilities. This book should also find a place on the shelves of fish biologists and physiologists and as a reference in libraries of universities, research establishments and aquaculture equipment companies.

Download or read book The Comparative Food Habits of Four Species of Fish from Medical Lake Washington written by Eric Anderson and published by . This book was released on 1987 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The purpose of this thesis was to compare and evaluate the food habits of four species of fish occupying Medical Lake, Spokane County, Washington, to determine if interspecific competition existed. The four species were rainbow trout (Salmo gairdneri), largemouth bass (Micropterus salmoides), tench (Tinea tinea), and goldfish (Carassius auratus). Assessment of interspecific competition was accomplished by comparing the relative importance indices, prey selection factors, and diet overlaps among species. The four species of fish partitioned their food resources to the extent that they avoided interspecific competition. Relative importance values indicate that each species usually contained separate dominant food categories in their diets. Tench and goldfish were more similar. The most important food of rainbow trout was the cladoceran Daphnia pulex. Relative importance values were consistently above 55% and prey selection factors above +0.786. Trout preyed on Daphnia to the extent that they decimated this food supply in 1981. This resulted in reduced weight and condition of trout. The lack of food caused an extensive trout kill in the fall of 1981. As opposed to trout, largemouth bass preyed extensively on aquatic macroinvertebrates. The mean relative importance values for the three- year study were highest for Ephemeroptera (30.3%), Odonata (16.0%), Diptera (15.8%), and fish (13.8%). Tench and goldfish exhibited the greatest similarity in their diets. Both contained large proportions of vegetative matter in their diets (three-year means of 32.3% and 21.3%, respectively). Goldfish also preyed extensively on Pleuroxus sp. (a littoral zone cladoceran) and tench preyed on the cladoceran Ceria- daphnia lacustris. Diet overlaps between species were usually low with the exception of mid-range overlaps between tench and goldfish. It appears that the diet separations were primarily manifested according to the habitat each species occupied. Trout and bass appeared to exhibit the greatest difference in habitat preference"--Document.

Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.

Download or read book Alternative Feeding Strategies to Maximize Marine Feedstuff Replacement in Largemouth Bass Micropterus Salmoides Culture While Maintaining Production Performance written by Andrew R. Coursey and published by . This book was released on 2011 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harvest of marine resources for feedstuff production is at its maximum sustainable yield and alternative feedstuffs are needed to supply livestock production for an expanding human population having a growing desire for seafood. Aquaculture is currently the fastest growing sector of agriculture, but the high cost and limited supplies of marine feedstuffs for aquafeeds could ultimately limit production of foodfish. Replacement of marine feedstuffs poses a dilemma, however, as replacement of fish meal can affect animal growth, and replacement of fish oil in aquafeeds leads to altered fillet fatty acid profiles without the maximum benefit of high omega-3 (n-3) and long-chain polyunsaturated fatty acids (LCPUFA) content. Two feeding trials were conducted to determine if poultry byproducts can replace fish meal and fish oil in diets for largemouth bass Micropterus salmoides without affecting production performance or fillet fatty acid composition. Poultry byproducts were able to replace fish meal and fish oil while maintaining production performance of largemouth bass, however, the altered fatty acid profiles of the feeds were reflected in the fillets. Finishing diets containing high levels of fish oil were implemented to restore n-3 and LC PUFA concentrations in the fillet. Twelve weeks of finishing proved suitable to partially restore n-3 and LC-PUFA concentrations while limiting the overall use of marine resources in the largemouth bass production cycle.

Download or read book Habitats and Biota of the Gulf of Mexico Before the Deepwater Horizon Oil Spill written by C. Herb Ward and published by Springer. This book was released on 2017-06-26 with total page 948 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 2.5 license. The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010. Unfortunately, baseline assessments of the status of habitats and biota in the Gulf of Mexico before these spills either were not available, or the data had not been systematically compiled in a way that would help scientists assess the potential short-term and long-term effects of such events. This 2-volume series compiles and summarizes thousands of data sets showing the status of habitats and biota in the Gulf of Mexico before the Deepwater Horizon Oil Spill. Volume 2 covers historical data on commercial and recreational fisheries, with an analysis of marketing trends and drivers; ecology, populations and risks to birds, sea turtles and marine mammals in the Gulf; and diseases and mortalities of fish and other animals that inhabit the Gulf of Mexico.
