Download or read book Selection and Breeding Programs in Aquaculture written by Trygve Gjedrem and published by Springer Science & Business Media. This book was released on 2005-04-13 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although aquaculture as a biological production system has a long history, systematic and efficient breeding programs to improve economically important traits in the farmed species have rarely been utilized until recently, except for salmonid species. This means that the majority of aquaculture production (more than 90 %) is based on genetically unimproved stocks. In farm animals the situation is vastly different: practically no terrestrial farm production is based on genetically unimproved and undomesticated populations. This difference between aquaculture and livestock production is in spite of the fact that the basic elements of breeding theory are the same for fish and shellfish as for farm animals. One possible reason for the difference is the complexity of reproductive biology in aquatic species, and special consideration needs to be taken in the design of breeding plans for these species. Since 1971 AKVAFORSK, has continuously carried out large scale breeding research projects with salmonid species, and during the latest 15 years also with a number of fresh water and marine species. Results from this work and the results from other institutions around the world have brought forward considerable knowledge, which make the development of efficient breeding programs feasible. The genetic improvement obtained in selection programs for fish and shellfish is remarkable and much higher than what has been achieved in terrestrial farm animals.
Download or read book Experiments in Personality Volume 1 Psychology Revivals written by H. J. Eysenck and published by Routledge. This book was released on 2013-10-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1960, the two volumes of Experiments in Personality report a number of experiments in psychogenetics, psychopharmacology, psychodiagnostics, psychometrics and psychodynamics, all of which formed part of the programme of research which had been developing from the late 1940s at the Maudsley Hospital. Presenting the studies together in a book, rather than the more usual route of journal articles, was itself felt to be an experiment at the time, especially given the wide area covered. The decision was deliberate because all the studies reported formed part of a larger whole, which would have been lost if published separately. Volume I looks at psychogenetics and psychopharmacology.

Available in PDF, EPUB and Kindle. Book excerpt: A history of the unsustainable modern diet—heavy in meat, wheat, and sugar—that requires more land and resources than the planet is able to support. We are facing a world food crisis of unparalleled proportions. Our reliance on unsustainable dietary choices and agricultural systems is causing problems both for human health and the health of our planet. Solutions from lab-grown food to vegan diets to strictly local food consumption are often discussed, but a central question remains: how did we get to this point? In Diet for a Large Planet, Chris Otter goes back to the late eighteenth century in Britain, where the diet heavy in meat, wheat, and sugar was developing. As Britain underwent steady growth, urbanization, industrialization, and economic expansion, the nation altered its food choices, shifting away from locally produced plant-based nutrition. This new diet, rich in animal proteins and refined carbohydrates, made people taller and stronger, but it led to new types of health problems. Its production also relied on far greater acreage than Britain itself, forcing the nation to become more dependent on global resources. Otter shows how this issue expands beyond Britain, looking at the global effects of large agro-food systems that require more resources than our planet can sustain. This comprehensive history helps us understand how the British played a significant role in making red meat, white bread, and sugar the diet of choice—linked to wealth, luxury, and power—and shows how dietary choices connect to the pressing issues of climate change and food supply.
