Abstract: Investigations were conducted on biological association of the blue crab
Callinectes amnicola with invertebrates’ organisms in the Great Kwa River, from July 2016 to September 2016. Results of the investigation revealed that four barnacle species namely
Balanus glandula, Chthamallus dalli, Chthamallus stellatus and
Semibalanus balanoides were in common association with the crab. Total of 15 (30.61%)
Balanus glandula were observed to be in association with the crab in, 12 (31.58%) in August and 14 (30.43%) in September.
Chthamallus dalli had 11 individuals (22.45%) in July, with 8 (21.05%) in August and 10 (21.74%) in September. In July, 13 (26.53%) of
Chthamallus stellatus were observed on the crabs with 11 (28.95%) in August and 9 (19.57%) in September, while
Semibalanus balanoides had 10 individuals (20.41%) in July with 7 (18.42%) in August and 13 (28.20%) in September. A hairy macro-algae in the Chrysophyceae family was also observed to symbiotically associate with the crab particular where the larval stages of the various barnacle species were found.
