National Fish Strain Registry: Trout Species Tables of Reported Strains and Broodstocks.

摘要

Prior to 1980, useful information on genetic traits, performance characteristics, and habitat preferences of fish populations was unavailable to fisheries managers to support decisions on the strains to be used in each production or management situation. Managers had little choice but to use the broodstock sources available to them for the fish needed to stock fisheries within their jurisdiction. Until recently, fish strains were shipped throughout the country and stocked in disparate fisheries before managers understood the potential long term detrimental implications for resident natural fish populations. The need for detailed information on managed fish populations increased dramatically as managers became aware of the genetic consequences of mixing adapted and non-adapted strains. In the late 1970s, the U.S. Fish and Wildlife Service undertook development of the Trout Strain Registry (TSR), a database of genetic, performance, and management information on trout strains used by natural resource management agencies and aquaculture organizations throughout the United States.
