Survey of the Blue Crab Populations in the Corpus Christi Bay Area - Studies of the Blue Crab Population of the Texas Coast

Seven stations in Corpus Christi, Nueces, Redfish and Oso Bays were sampled semi-monthly with an otter trawl. Results show peaks of abundance in February and in May, followed by a rapid decline in June as salinity increased. By August, salinity went up to over 40 ppt. and crabs became very scarce. The sex ratio was uneven, particularly in May when out of 262 crabs taken, 195 (75 per cent) were females.
