It’s common practice for hatcheries managers to elevate rearing water temperatures. Elevated rearing temperatures helps smolt gain weight and promises higher smolt to adult survival. Is it translating to higher fishery returns? (1/5)

Factors affecting survival rates of migratory salmon include olfactory imprinting, photoperiod, flow, and water temperature/chemistry. Although elevating water temperatures is standard practice, it is not proven to return higher amounts of salmon from the ocean. (4/5)
