Description: Abstract: The National Fish Broodstock Registry (NFBR) was initiated in 1991 as a cooperative project of the Fish and Wildlife Service division of Fish Hatcheries and the National Biological Service, Research and Development Laboratory.
The NFBR consists of a series of databases designed to catalog performance information on managed wild and domestic broodstocks of six fish families: trout (salmonidae, excluding anadromous salmon), catfish (Ictaluridae), sturgeon (Acipenseridae), paddlefish (Polyodolontidae), perch (Percidae), and sunfish (Centrarchidae).
While broodstock information is needed on all managed fish species, the separate databases of the NFBR have been developed sequentially starting with the species where broodstock information has been developed.
