Description:

"The Division of Resource Ecology and Fisheries Management is formulating a Dynamic Numerical Marine Ecosystem (DYNUMES) Model for use in evaluating interactions of environmental and biological components. Initially, the model will be used in reference to the economically important eastern Bering Sea area, and a preliminary submodel which permits evaluation of the inter- - actions of only 8 representative biological components in the area has been tuned to assess rough biomass balances. As a first step we have modelled general zooplankton consumption and compared this with zooplankton abundance. Results indicate that the monthly consumption is roughly equivalent to the monthly standing stock, an impossible situation. The usefulness of existing plankton data, which are obviously more qualitative than quantitative, in biological or ecosystem models is challenged, and cooperative integrated plankton and fisheries field studies are recommended to resolve the apparent dilemma."
