Description

The focus of this project is to continue research, monitoring and evaluation components of the Lake Ozette Sockeye population, and to track and evaluate the performance of the overall status of this population of ESA listed salmon. The major components are:

Task A) Lake Ozette Sockeye smolt trapping in the Ozette River during outmigration provides an estimate of total sockeye smolt production. Hatchery and natural origin smolts are enumerated separately, as are all other salmonid species encountered.

Task B) Spawner surveys and sample collections will be conducted on Lake Ozette beaches and in many of the Ozette tributaries. Surveys for spawning sockeye in Lake Ozette tributaries and on the beaches are conducted between October and January. Sonar imagery may be used to provide supplemental surveys for the beach spawners. Otoliths are collected from carcasses, during beach carcass counts to determine age and release group.

Task C) Adult sockeye run-size entering Lake Ozette is monitored annually to help estimate overall abundance. The adult sockeye run is recorded with sonar imagery. Fish passages are recorded 24/7 and population estimates are subsequently compared to estimates from both the adult weir at Umbrella Creek and the stream spawner surveys. Predator encounters and general fish condition are also evaluated.

Project Benefit

This project, in combination with the hatchery program, will allow Makah Fisheries Management to:

• Estimate the total number of adult sockeye entering Lake Ozette and separate the total into different spawning aggregation estimates.

• Determine the relative contribution of hatchery origin spawners in tributaries and monitor stray rates at all spawning locations.

• Estimate total sockeye smolt outmigration and relative hatchery contribution and survival in freshwater.

• Monitor smolt outmigration of other resident Lake Ozette salmonid populations.

• Identify all hatchery returns by release group and thus facilitate evaluation of performance and impacts of various hatchery programs.

• Collect and archive genetic samples for future monitoring and comparison.
