The zooplankton of Bear Cut was quantitatively sampled for one year. There were four peaks of plankton production throughout the year, the reasons for which are discussed in the light of local weather conditions. Copepods accounted for a consistently high proportion of the total, though several species had different peaks of abundance during the year. Most of the plankton groups were represented in every plankton sample, but there was a far higher proportion of young copepods and young chaetognaths in the summer. Size frequency distributions were determined for the chaetognath, Sagitta hispida, and seasonal peaks for the main temporary plankton are recorded. The hydrography of Biscayne Bay is discussed in relation to the origins of the plankton in Bear Cut, and comparison is drawn between the observations of other workers in neritic tropical waters.
