Creator:: Bissonnette, Pam, Taub, F. B. (Frieda B.), U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Macroinvertebrates were sampled on a regular basis from March to October 1973. A relationship between chironomid length and biomass was established. Production equations to be used for these insects are reported. A similar length/weight relationship is presently being explored for the oligochaetes. A proposal is made for calculating their production...

Creator:: Wydoski, Richard S., Whitney, Richard R., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: To determine productivity of fish, we will require an estimate of relative abundance that can be expanded later into estimates of biomass. Our work has shown that much of the fish production in Lake Washington is in the form of nonsalmonid and nongame species, such as peamouth and northern squawfish....

Abstract:: The Washington Cooperative Fishery Unit at the College of Fisheries, University of Washington, Is carrying on studies of fishes in Lake Washington as part of the International Biological Program sponsored by the National Science Foundation. One of our interests Is. in the effects of temperature on the movements of fishes...

Abstract:: The objectives for year have been the gathering of existing information, initiation of monitoring water quality, evaluation of analytical methods and procedures for measuring nutrient regeneration in the sediment-water interface, and the study of growth-environment correlations in Findley Lake, Chester Morse Reservoir, and Lakes Sammamish and Washington. Progress was made...

Abstract:: Grazing rates and density of the crustacean zooplankton were measured in Findley and Chester Morse Lakes and Lake Sammamish, Washington. Sample analysis is incomplete at reporting time, thus estimates of production from examination of life stage biomass changes was not possible. Maximum density of crustacean zooplankton was about 10/1 in...

Creator:: Welch, E. B. (Eugene B.), Hendrey, George R., Rock, C. A., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Lakes Findley, Chester Morse and Sammamish, Washington, are characterized by one major outburst of phytoplankton productivity and biomass (mainly diatoms) with usually no or low fall activity. Vernal outbursts were often delayed in some lakes and years probably by unfavorable climate (snow cover and cloudy rainy conditions). Mean spring-summer productivity...

Abstract:: The food habits of yellow perch in Lake Washington were studied over a period of nine months. Altogether, 549 yellow perch were examined for the stomach contents. The food consisted mainly of cottids, mysid shrimp, and chironomid pupae and larvae; the predominant food item being the mysid shrimp. There was...
