Tilapia production from aquaculture worldwide has grown rapidly, increasing from 241,681 metric tons (MT) in 1986 to 472,969 MT in 1992 (FAO, 1994). This growth has been facilitated in part through improvements in tilapia fry and fingerling productio

Improvement of iteroparity rates in U.S. Endangered Species Act (ESA)-listed Snake River populations of steelhead Oncorhynchus mykiss requires a means of distinguishing prespawn (mature) steelhead from postspawners (kelts) and sufficient kelt abundan

We sought to develop a rapid, noninvasive, and accurate method for distinguishing prespawn (mature or maturing) adult steelhead (anadromous rainbow trout Oncorhynchus mykiss) from postspawn adults (kelts). Ultrasound images of gonads were collected,

In sturgeon aquaculture, it is advantageous to sex fish as early as possible so that males can be used for meat production and females reserved for caviar production. Currently, growers wait 3 to 4 years before fish are sexed by an invasive surgical

We evaluated the effect of short-term exposures to a xenobiotic chemical during early life-history stages on the long-term immune competence of chinook salmon (Oncoryhnchus tshawytscha). Immersion of chinook salmon eggs in a nominal concentration of

The cultural and ecological values of Pacific lamprey (Lampetra tridentata) have not been understood by Euro-Americans and thus their great decline has almost gone unnoticed except by Native Americans, who elevated the issue and initiated research to

Because white sturgeon Acipenser transmontanus show no readily discernible external signs of gender, management agencies use surgical biopsies to determine the sex and stage of gonadal maturity of individuals. This procedure is highly invasive and ca
