The author reports on progress from April 1994 through March 1995 of research on white sturgeon in the lower Columbia River. The study began in July 1986 and is a cooperative effort of federal, state and tribal fisheries entities to determine the (1) the status and habitat requirements, and (2) the effects of mitigative measures on productivity of white sturgeon populations in the lower Columbia River. This report describes activities conducted during the third year of this contract's second phase. Information was collected, analyzed, and evaluated on sub-adult and adult life histories, population dynamics, quantity and quality of habitat, and production enhancement strategies. The report is divided into sections that evaluate success of developing and implementing a management plan for white sturgeon; evaluate growth, mortality, and contributions to fisheries of juvenile white sturgeon transplanted from areas downstream; describe the life history and population dynamics of sub-adult a nd adult white sturgeon; define habitat requirements for spawning and rearing of white sturgeon and quantify the extent of habitat available; describe reproductive and early life history characteristics of white sturgeon; and quantify physical habitat used by spawning and rearing white sturgeon in the free-flowing portion of the Columbia River.
