Staff biologists have observed broodstock spawning, documented creation of viable redds by fry trapping, documented juvenile production to the parr lifestage by electrofishing, and trapped emigrating smolts. However, during redd count surveys, BSRFH staff observations suggest approximately 50% of the adult salmon transplanted in a spawning stream are not seen during spawning.","EngDescr":" It is uncertain if the unobserved adults are being removed from the stream by predators or poachers, or if they are experiencing mortality due to decreased fitness or stress prior to spawning. It is also possible that broodstock are leaving the transplanted stream and spawning in other areas of drainages. Movement of adults outside study reaches potentially confounds wild salmon return estimates, may lead to negative biological interaction with wild conspecifics, and limits agency ability to fully assess juvenile production potential of captive-reared broodstock. Further assessment of the movements and behavior of transplanted broodstock before, during, and after spawning is needed. The objectives of this study are: (1) to document captive-reared gravid adult Atlantic salmon broodstock spawning behavior, locations, and movements within a release stream or in other reaches of a drainage; (2) quantitatively assess juvenile production from in-river spawning of captive-reared broodstock for comparison with production from fry point stocking; (3) document post-spawn movement of kelts; and (4) document post-spawn habitat used by overwintering kelts. \r\n
