Abstract
Studies were made in Core Sound, North Carolina to determine the abundance and distribution of juvenile blue crabs,Callinectes sapidus, and their subsequent relation to the commercial fishery. Estimates of juvenile abundance were based on catches of small crabs in the marsh creeks bordering Core Sound. Young-of-the-year blue crabs (2.5–5.0 mm) begin to enter Core Sound estuary in early October. These small crabs move through the open waters of the sound and bays into the small marsh creeks and remain there until the following spring. At this time (April–May) the juvenile crabs move into the bays and sound proper where they remain to maturity. Catch and effort statistics from Core Sound Commercial crab fishery were collected from November 1964 through June 1968. Landings of approximately 680,000 kg annually constitute the fishery.
