Limnetic Zooplankton Dynamics In Beaver Reservoir Including An Inventory Of Copepod Species And An Evaluation Of Vertical Sampling Methods, Eugene H. Schmitz Jan 1974

Limnetic Zooplankton Dynamics In Beaver Reservoir Including An Inventory Of Copepod Species And An Evaluation Of Vertical Sampling Methods, Eugene H. Schmitz

Technical Reports

There can be little doubt that the development of primary food sources (i.e. plankton) is an important factor contributing to fish production. Applegate and Mullan (1968) report that an exceptional sport fish harvest is generally associated with the development of new reservoirs, although the precise reasons for such interrelations are not known. Kramer and Smith (1962) demonstrated the tendency of bass fingerlings to feed on Cladocera in proportion to the latter's abundance, and Hodson (1966) reported the same basic pattern for largemouth and spotted bass fingerlings in Beaver Reservoir. Applegate and Mullan (1969) analyzed the digestive tract contents of larval …
