Bacterial have been one the major diseases that affect shrimp and give a setback for shrimp farming in aquaculture industry and various fish market. These bacterial infection were been transferred through various medium such as sea water, management practices and handling. A total number of twelve (12) specimen which include carapace, guts and exoskeleton were sampled from Olomore market, Abeokuta axis, Ogun state to investigate the morphometric, meristic and bacteriology in Caridean shrimp. This study revealed that there were no significant difference (P≥0.05) in the morphometric, meristic and total bacterial count of the shrimp stomach, carapace and body. However, the cephalothorax length (CL) showed a significant between the male (0.1-0.5) and female (0.1-1.5). This indicated that the female CL is thrice the male. In the meristic, rostral spine was slightly varied between the male (4-7) and female but had the same value with the total (4-8). All the bacterial identified are resistance to Augmentin, Zinnacef, Erythomyin, Gentanycin and Pefloxacin except for Bacillus spp which are sensitive to Gentanycin and Pefloxacin. Therefore, this present study revealed that the female and female Caridean shrimp have similar morphological and meristic features and the identified bacterial can be treated with any of the antibiotics except Augmentin, Zinnacef, Erythomyin, Gentanycin and Pefloxacin.
