“…Conventionally, movement and recapture data have been used to assess optimal age and size to release stocked fish (Pycha and King, 1967;Behmer et al, 1993), identify appropriate seasons to plant fish (Buettner, 1961;Hansen and Stauffer, 1971;Elrod, 1987), assess the most appropriate genetic strain (Elrod, 1987;Elrod and Schneider, 1987), and employ tagging methods that ensure the greatest degree of stock survivability (Buettner, 1961;Behmer et al, 1993). Based on recaptures from recreational anglers, Behmer et al (1993) suggested that stocking of Atlantic Salmon (Salmo salar) in the St. Marys River should occur in early June and at the largest size. Recapture data can also be incorporated into models to generate movement, survival, mortality, and abundance estimates (Fielder and Thomas, 2006;Glover et al, 2008;Haas et al, 1988).…”

Life stage and vaccination shape the gut microbiome of hatchery-reared Atlantic salmon (Salmo salar)

“…Although natural reproduction has been observed in the St. Marys River, Michigan (16), there is no evidence that recruitment to adulthood is sufficient to sustain a population. Fisheries are therefore dependent on stocking hatchery-reared Atlantic salmon, but stocking programs have shown variable success and often poor return rates (0-2%) (15,(17)(18)(19)(20).…”

“…Although natural reproduction has been observed in the St. Marys River, Michigan (16), there is no evidence that recruitment to adulthood is sufficient to sustain a population. Fisheries are therefore dependent on stocking hatchery-reared Atlantic salmon, but stocking programs have shown variable success and often poor return rates (0–2%) (15, 17–20). Given that the stocking success of hatchery-reared individuals may be linked to the gut microbiome (21, 22), understanding how different environmental and host-associated factors shape the microbiome may be essential for improving hatchery success.…”
