Maximum Sustainable Yield

Maximum Sustainable Yield

Featuring: SHANNON & ALEX

Measuring the harvest and escapement numbers of specific species assists Alaska’s Department of Fish and Game in their deployment of a viable fishery management strategy. This strategy is one that considers time, area and gear type for catching different fish.

The goal? Provide for optimal harvests while sustaining each salmon species.

Each morning Sockeye and Chinook salmon are sampled in the “trap”. Research includes tracking of returning adult salmon, a DNA analysis in every system in Yakutat, and age, sex and length sampling.

MSY (maximum sustainable yield) is a viable management strategy for salmon because we understand large parts of the fresh water life cycle, control to some extent escapement onto spawning grounds, and manage time and gear to attain escapement goals necessary to perpetuate the species while allowing its optimal harvest. Yakutat Fisherman rely on daily escapement information from the weir.
