Abstract

The zooplankton of Chesapeake Bay occurs as two definable, seasonal populations: a summer-fall community, peaking in August, and a winter-spring assemblage, peaking in February or March (Grant 1977; Jacobs 1978). A minimum of two surveys per year are therefore required for long-term assessment of these communities: March and August have been selected as sampling months. Adequate assessment of meroplankton, particularly fish eggs and larvae and the larvae of decapod crustaceans, requires sampling over the principal reproductive period of June through August (Goy 1976; Olney 1978). Surveys for these components only are to be conducted in June and July, in addition to the full taxonomic surveys of March and August.

The present report includes results of the first monitoring cruise of March 27-30, 1978.
