Population Studies of the Blue Crab Callinectes sapidus Rathbun in the Aransas Bay Area - Studies of the Blue Crab Populations of the Texas Coast


In 1964 10-foot trawl samples, blue crabs (Callinectes sapidus) were 92 per cent less abundant than in 1961, while bar seine samples showed a 56 per cent decrease in abundance over 1962 figures. Bar seine samples in 1964 showed an increase in crab abundance by 25 per cent as compared to 1963. The decrease in crab landings since March 1962 may be contributed to a reduction of river flow and runoff which have induced higher salinities throughout the bay system.
