This study was made to estimate seasonal abundance, growth, mortality and biomass of planktivore fish by species and age groups
on Lake Washington, Lake Sammamish, and Chester Morse Lake, and to incorporate this information with other studies to test trophic dynamics models. Work in the initial year was directed toward...
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...
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....
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...
The purpose of the past year's research was to begin measurement of the respiratory metabolism of zooplankton and phytoplankton in four lakes in the Lake Washington drainage. This was done, using an enzyme assay for the activity of the electron transport system. The lakes were sampled frequently and depth profiles...
