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.

Available in PDF, EPUB and Kindle. Book excerpt: The basic principle of all molecular genetic methods is to employ inherited, discrete and stable markers to identify genotypes that characterize individuals, populations or species. Such genetic data can provide information ori the levels and distribution of genetic variability in relation to mating patterns, life history, population size, migration and environment. Although molecular tools have long been employed to address various questions in fisheries biology and management, their contributions to the field are sometimes unclear, and often controversial. Much of the initial impetus for the deployment of molecular markers arose from the desire to assess fish stock structure based on various interpretations of the stock concept. Although such studies have met with varying success, they continue to provide an impetus for the development of increasingly sensitive population discriminators, yielding information that can be valuable for both sustainable exploitation and the conservation of fish populations. In the last major synthesis of the subject, Ryman and Utter (1987) summarized progress and applications, though this was prior to the wide-scale adoption of DNA methodology. New sources of genetic markers and protocols are now available, in particular those that exploit the widely distributed and highly variable repeat sequences of DNA, and the amplification technique of the polymerase chain reaction.

Download or read book Maternal Effects As Adaptations written by Timothy A. Mousseau and published by Oxford University Press. This book was released on 1998-06-18 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mothers have the ability to profoundly affect the quality of their offspring--from the size and quality of their eggs to where, when, and how eggs and young are placed, and from providing for and protecting developing young to choosing a mate. In many instances, these maternal effects may be the single most important contributor to variation in offspring fitness. This book explores the wide variety of maternal effects that have evolved in plants and animals as mechanisms of adaptation to temporally and spatially heterogeneous environments. Topics range from the evolutionary implications of maternal effects to the assessment and measurement of maternal effects. Four detailed case studies are also included. This book represents the first synthesis of the current state of knowledge concerning the evolution of maternal effects and their adaptive significance.
