Genetic Variation for Disease Resistance in Rainbow Trout

Download or read book Genetic Variation for Disease Resistance in Rainbow Trout written by Gareth Butterfield and published by LAP Lambert Academic Publishing. This book was released on 2012-05 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proliferative Kidney Disease (PKD) caused by the Malacosporean parasite Tetracapsuloides bryosalmonae, is the most economically damaging disease of British rainbow trout farming, costing the industry in excess of £2.5 million per annum. With no vaccine or prophylactic treatment available, and only management techniques currently adopted to minimise the stress and mortality associated with the disease, the research undertaken within this book addresses a potential alternative approach; selective breeding. The book will explain the investigation undertaken to identify that selective breeding for PKD resistance is possible, and how the level of additive genetic variation was calculated, allowing estimates of heritability to be documented for commercial strains of rainbow trout (Oncorhynchus mykiss).
