Settlement Patterns of Callinectes Sapidus Megalopae in Mississippi Sound: 1991, 1992
Daily sampling for blue crab megalopae was conducted from May through November 1991 and 1992 in Mississippi Sound. Settlement was highly episodic in both years. Temporal periodicity of major settlement events was similar in 1991 and 1992 with highest settlement in late summer/early fail. Peak settlement occurred on 17 August of 1991 when 7,676 megalopae per sampler were collected. Statistically, little or no relationship was observed between settlement events and temperature, salinity, predicted astronomical tides, lunar period and average daily wind direction and speed. Qualitative examination of meteorologic and hydrologic parameters surrounding peak settlement episodes showed settlement occurred under a variety of conditions; however, spring tides coupled with onshore winds were associated with the majority of high settlement events.
