Ecological studies on the fresh-water phases of the life history of sockeye salmon and studies on related limnology and climatology were made at Brooks Lake, Alaska, in 1957. Data are presented and interpreted on adult sockeye salmon spawning distributions and behavior, age, sex, length, fecundity, and bear predation; on juvenile sockeye salmon ages, food, growth, migration from the lake, relative abundance, and distribution in the lake; and on climatological and limnological factors that may influence sockeye salmon behavior and abundance.

Excerpt from Intertidal Ecology and Life History of Pink Salmon at Olsen Creek, Prince William Sound, Alaska Twelve pink salmon streams in Port Gravina in addition to Olsen Creek were surveyed once a week to check for emigrant tags (fig. A summary of the recovery data is given in table 4. Tagged fish taken in the commercial fishery and those found in the Port Gravina streams were considered emigrants and were subtracted from the total tagged to correct population estimates. The following formula was used to estimate the total spawning population from the ratio of tagged to untagged carcasses.
