The application of genomic approaches to rainbow trout aquaculture

水产养殖是一个日益增长的就业来源，并为工业替代品有限的社区提供了改善社会和经济的可能性。安大略省是加拿大虹鳟鱼的主要产地，供人类食用。尽管安大略省鳟鱼的市场需求和消费者接受度非常高，但养殖鱼产品的进口仍主导着市场。加拿大鳟鱼水产养殖的发展受到当地生产者无法向生长笼提供种料的限制。由于雌性的产卵时间有限，生产集中在一年内。此外，已建立的菌株在提高生长速度和防止早熟等经济上重要的性状方面相对没有得到改善。我们的长期目标是提供分子遗传信息，这将加快虹鳟鱼品种的发展和独特适合加拿大的可用性

Aquaculture is a growing source of employment and offers the possibility for social and economic improvements in communities with limited industrial alternatives. Ontario is the major Canadian producer of rainbow trout for human consumption. Even though market demand and consumer acceptability for Ontario trout is very strong, imports of farmed fish products dominate the marketplace. The development of Canadian trout aquaculture is limited by the inability of local producers to supply seedstock to grow-out cages. Production is concentrated within the year because of the restricted spawning time of females. Also, established strains are relatively unimproved for economically important traits such as increased growth rate and the prevention of early maturation. Our long term goal is to provide the molecular genetic information that will expedite the development and availability of rainbow trout strains that are uniquely suited to Canadian
