This book was released on 1986 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two rainbow trout (Salmo gairdneri) reference diets (a practical reference (control) diet (C201) formulated for feed development studies and semipurified reference (basal) diet (C101) for nutrient requirement studies) were used in a 16-wk feeding trial to investigate their suitability for Arctic charr (Salvelinus alpinus). Biochemical and performance parameters together with gross morphological and histological evidence showed that diet C201 was a suitable reference diet for feed development studies in Arctic charr. It produced no pathological conditions. However diet C101 was not suitable for nutrient requirement studies in Arctic charr; compared to diet C201 it produced high mortalities, lower weight gains (growth) and low hematocrit values. It resulted in liver which was beige-gray in color, had an abnormal glycogen distribution and accumulation and had a higher weight to body weight ratio. This abnormal liver had a higher content of lipid (dry weight), moisture, calcium, iron and cobalt and a lower content of fat-free solids, copper, magnesium, and zinc. Diet C101 also produced higher whole body contents of manganese, and cobalt and lower content of selenium.

Available in PDF, EPUB and Kindle. Book excerpt: This volume analyzes and discusses the various activities of plant and animal life and behaviour and their relationship to industry. It covers the history of aquaculture and its importance to various countries; its present status and future prospects worldwide. Aquaculture research is discussed in relation to biological and technological sciences, both of which have been heavily involved in recent years. It also examines various modelling and simulation techniques for improving both aquacultural environments and for studying fish behavioural patterns. It includes two reports from the panel sessions on "Educational needs in aquaculture engineering with special reference to automation" and "The need for reliable and robust measuring devices in aquaculture facilities".

Book excerpt: Prediction equations correlating density of fingerling rainbow trout with growth, yield, and food use efficiency indicated that ammonia nitrogen resulting from high fish densities wes responsible for reductions in all three factors. These predictable density-dependent responses present fish-culturists with alternatives of density selection for evaluation and attainment of specific goals. In examples, fish-culturists, by manipulating density, could achieve rapid growth, produce the maximum weight possible, balance yield with cost, optimize fish quality, or combine two or more of these goals.

Download or read book Intra-strain Inheritance of Growth and Survival in Rainbow Trout, Salmo Gairdneri Richardson, Reared in Two Hatchery and Two Prairie Winterkill Lake Environments written by John Kenneth Bailey and published by . This book was released on 1978 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intra-strain inheritance of growth and survival in rainbow trout (Salmo gairdneri), reared for 8-10 months in 2 hatchery and 2 prairie winterkill lake environments, was studied by means of a hierarchal mating design. Statistical determinations were made on both individual values and full sib family means. The implications for the genetic improvement of rainbow trout for extensive aquacultural purposes are discussed. Individual heritability values for fork length and weight were respectively, 0.09 and 0.06 in the non-competitive hatchery environment, 0.27 and 0.23 in the competitive hatchery environment, 0.09 and 0.00 in lake 971 and 0.27 and 0.04 in lake 506. Fork length and weight heritability estimates determined from full sib family means were much larger in all environments and were respectively, 0.58 and 0.42 in the non-competitive hatchery environment, 0.99 and 0.94 in the competitive hatchery environment, 1.08 and 0.50 in lake 971, and 0.78 and 0.74 in lake 506. In lakes 971 and 506 heritability estimates for individual survival were 0.18 and 0.02 respectively and for full sib family means they were 1.07 and 0.53 respectively. Inter-family competition caused a magnification of genetic differences between hatchery environments and was unimportant in the lake environments. Family selection is expected to produce a more rapid response in growth and survival than individual or mass selection. Genotype-environment interactions were important in all environments. Artificial selection would be more effective in the intended environment than in the hatchery. Additive genetic, environmental, and phenotypic correlations between fork length and weight were large and positive in all environments. Simultaneous selection for these traits would be effective.
