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...
