Redoubt Lake Russian America. The Russians established a small settlement near the lake's outlet known variously as Ozersk Redoubt, Ozyorsk Redoubt, The Redoubt, Seleniye Dranishnikova, or Dranishnikov Settlement. Salmon traps were set in the lake and the catch was salted and dried at Ozersk Redoubt. Between 1817 and 1832 the Russians at Sitka and Ozersk Redoubt salted an average of 20,000 salmon annually. Fish harvests by the Russians at Redoubt Lake sometimes exceeded 50,000 sockeye salmon per year. Annual escapements possibly exceeded 100,000 sockeye. In the 1980s, sockeye escapement or returns of adult fish had declined to an average less than 10,000
Sockeye salmon in freshwater lakes. The majority of sockeye spawn in rivers near lakes and juveniles will spend one to two years in the lake before migrating to the ocean, although some populations will migrate to saltwater in their first year. Adult sockeye will spend two to three years in the ocean before returning to freshwater. Females will spawn in 3–5 redds over a period of several days. The eggs usually hatch within six to nine weeks and the fry typically rear in lakes before migrating to the ocean. Males partake in competitive and sneaking tactics, formation of hierarchies, and non-hierarchical groupings
