Weekly abundance of larval blue crabs CaUinectes sapidus was determined during late summer (1983 and 1984) at 15 stahons on the inner continental shelf within 50 km of Delaware Bay, USA. Simultaneous measurements of subtidal, surface flow were made at 5 current meter stations within the study area. During both years, larval abundance was greatest during early August when concentrations in excess of 100 zoeae m-3 were commonly observed. By the thud week in September, early zoeal stages had &sappeared from the water column, and zoeal abundances at all stations were less than 10 zoeae Results of the current meter measurements provide firm evidence of sustained northward flow of surface water on the inner shelf off Delaware Bay during late summer when C. sapidus larvae are common in the plankton. This northward flow occurs on time scales relevant to the rate of larval development of C. sapidus and may b e important in retaining zoeae near the parent estuary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
