Book Synopsis Temperature and Genetic Effects on Growth, Body Shape, and Sprint Swim Speed in Rainbow Trout by : Christopher Steven Duke
Download or read book Temperature and Genetic Effects on Growth, Body Shape, and Sprint Swim Speed in Rainbow Trout written by Christopher Steven Duke and published by . This book was released on 2021 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultimate phenotype for a given trait results from the combined influences of underlying genetics and environmental factors; predicting how organisms respond to changing environments thus depends on understanding the relative impacts of genes and environmental variables on phenotypes. Here, I explore how changes in one of the most fundamental environmental variables, temperature, impact phenotypes with strong survival implications for rainbow trout (Oncorhynchus mykiss), and explore the underlying genetic architecture associated with phenotypic change in response to temperature. In this dissertation, I begin by comparing responses of growth, size, body shape, and sprint swimming speed phenotypes to rearing at 10° C and 18° C in two geographically disparate, semi-wild clonal strains of O. mykiss (Whale Rock clonal line, from California, and Swanson clonal line, from Alaska), compared to two clonal strains with hatchery origins (Arlee and Hot Creek clonal lines). I find that Whale Rock and Swanson overall show the greatest between-line differences in these phenotypes, and vary notably in the nature and magnitude of their plastic response to temperature. I then explore the influence of 10° C and 18° C rearing temperature on the location of body fins that potentially influence sprint swimming speeds (dorsal fin, anal fin, and pelvic fins) at 32 and 35 weeks of age in Whale Rock and Swanson clonal lines, with Hot Creek as a hatchery-origin clonal line for comparison. I find complex patterns of variation in fin location at both ages, both within clonal line at different temperatures and between clonal lines within the same temperature. Of the fin locations measured, only one was found to significantly influence sprint swimming speed, which was the distance between the operculum and the most anterior margin of the anal fin. Whale Rock and Swanson showed distinctly disparate differences in fin metrics, again suggesting their suitability for exploring genetic architecture of these phenotypes. Finally, I use a quantitative genetic approach to identify quantitative trait loci (QTL), finding evidence for significant and suggestive QTL influencing the measured phenotypes, as well as evidence for temperature-specific QTL.

Download or read book Edible Insects written by Arnold van Huis and published by Bright Sparks. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.

Download or read book Small-scale Aquaponic Food Production written by Christopher Somerville and published by Fao. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.

Download or read book Alternative Proteins written by Alaa El-Din A. Bekhit and published by CRC Press. This book was released on 2022-01-20 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, there has been substantial research dedicated towards prospecting physiochemical, nutritional and health properties of novel protein sources. In addition to being driven by predictions of increased population and lack of a parallel increase in traditional protein sources, main drivers for the rise in novel proteins/ novel foods research activities is linked to significant changes in young consumers’ attitudes toward red meat consumption and their interest in new alternative protein products. Alternative Proteins: Safety and Food Security Considerations presents up-to-date information on alternative proteins from non-meat sources and examines their nutritional and functional roles as food sources and ingredients. Emphasis is placed on the safety of these novel proteins and an evaluation of their potential contribution to food security. Motivations for novel proteins and restrictions for their use are also discussed. Key Features: Explains potential improvements to alternative proteins through the employment of novel processing techniques. Contains the first review on keratin as an alternative protein source. Explores first comprehensive evaluation of the religious aspects of novel proteins. Describes methods for the detection and evaluation of health hazards. Discusses guidelines, regulatory issues and recommendations for food safety Additionally, this book covers fundamental and recent developments in the production of alternative proteins, and examines safety and consumer acceptability wherever information is available. The sources and processing options for alternative proteins and their impact on final product characteristics are also covered. A collective contribution from international researchers who are active in their field of research and have made significant contributions to the the food sciences, this book is beneficial to any researcher interested in the the food science and safety of alternative proteins.

Book Synopsis Genomics in Aquaculture to Better Understand Species Biology and Accelerate Genetic Progress by : José Manuel Yáñez
Download or read book Genomics in Aquaculture to Better Understand Species Biology and Accelerate Genetic Progress written by José Manuel Yáñez and published by Frontiers Media SA. This book was released on 2016-09-15 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a global perspective aquaculture is an activity related to food production with large potential for growth. Considering a continuously growing population, the efficiency and sustainability of this activity will be crucial to meet the needs of protein for human consumption in the near future. However, for continuous enhancement of the culture of both fish and shellfish there are still challenges to overcome, mostly related to the biology of the cultured species and their interaction with (increasingly changing) environmental factors. Examples of these challenges include early sexual maturation, feed meal replacement, immune response to infectious diseases and parasites, and temperature and salinity tolerance. Moreover, it is estimated that less than 10% of the total aquaculture production in the world is based on populations genetically improved by means of artificial selection. Thus, there is considerable room for implementing breeding schemes aimed at improving productive traits having significant economic impact. By far the most economically relevant trait is growth rate, which can be efficiently improved by conventional genetic selection (i.e. based on breeding values of selection candidates). However, there are other important traits that cannot be measured directly on selection candidates, such as resistance against infectious and parasitic agents and carcass quality traits (e.g. fillet yield and meat color). However, these traits can be more efficiently improved using molecular tools to assist breeding programs by means of marker-assisted selection, using a few markers explaining a high proportion of the trait variation, or genomic selection, using thousands of markers to estimate genomic breeding values. The development and implementation of new technologies applied to molecular biology and genomics, such as next-generation sequencing methods and high-throughput genotyping platforms, are allowing the rapid increase of availability of genomic resources in aquaculture species. These resources will provide powerful tools to the research community and will aid in the determination of the genetic factors involved in several biological aspects of aquaculture species. In this regard, it is important to establish discussion in terms of which strategies will be more efficient to solve the primary challenges that are affecting aquaculture systems around the world. The main objective of this Research Topic is to provide a forum to communicate recent research and implementation strategies in the use of genomics in aquaculture species with emphasis on (1) a better understanding of fish and shellfish biological processes having considerable impact on aquaculture systems; and (2) the efficient incorporation of molecular information into breeding programs to accelerate genetic progress of economically relevant traits.
