Determinants of stream life, spawning efficiency, and spawning habitat in pink salmon in the Auke Lake system, Alaska
Variation in stream life, spawning efficiency, and spawning habitat among adult pink salmon (Oncorhynchus gorbuscha) in the Auke Lake system, southeastern Alaska, was best explained by stream discharge, stream temperature, and a combination of stream temperature and discharge. We estimated these att...
