Recommendations for future work include expanding the littoral surveys into the north end and obtaining information on the diet of littoral species. These results will provide a better understanding of the temporal and spatial variation that occurs in fish assemblages in the nearshore environments. Additionally, it will provide information to assess the consumption and potential impact of nearshore fish on zooplankton availability. Bass may consume as many as 194,201 juvenile salmonid smolts annually, which is smaller than the impact of squawfish. The amount of spatial overlap between the bass species and the juvenile sockeye salmon using ultrasonic tracking techniques was examined, and the species all appear to be spatially separated.
More smallmouth bass exist in the lake than largemouth bass compared to earlier years.
Stomach analyses was performed on the bass species to determine the percentage of their diets which consists of juvenile salmon, and the diets of the two bass species appear similar relative to salmonid smolts. The bass were be tagged in order to estimate the population sizes as well as to receive additional movement and habitat data. The potential impact of each species of bass on the juvenile salmon in Lake Washington appears to be small on a relative scale. In experimental tanks smallmouth bass appeared to favor young salmonids as prey items.
