Microbial spectrum and antibiogram of bacteria isolated from Panulirus regius of the coast of Lagos were analysed using standard techniques. The lobster head had higher total bacteria and total coliform counts with respective significant (P < 0.05) values of 4.17 x 106 ± 1.46 CFU g−1 and 3.06 x 103 ± 1.56 CFU g−1. A higher total fungi count (2.99 x 102 ± 1.63) was recorded in the lobster tail. In the bacterial group, Bacilus megaterium had the highest frequency of occurrence (22.6%) while in the fungal group, Aspergillus niger had the highest frequency of occurrence (20.0%). All isolates were sensitive to ciprofloxacin and showed resistance to rocephin and zinnacef except Micrococcus sp. and Salmonella sp. The presence of antibiotic-resistant bacteria from the lobsters is a serious concern.

Proximate composition of the wild-caught Sarotherodon melanotheron and the socioeconomic analyses of cast net among artisanal fishers in Lagos Lagoon (Nigeria), were examined in the dry season of 2021 and 2022. No significant (P < 0.05) variation was found in the proximate content of the fish. The protein content ranged from 61.74 ± 3.20 g/100 g to 63.13 ± 0.64 g/100 g in 2021 and from 53.13 ± 3.27 g/100 g to 58.38 ± 0.47 g/100 g in 2022, with highest value in November 2021 and decreased thereafter till late dry season (April). Lipid content showed the opposite trend (except in February), increasing from early to late dry season. The return on investment averaged at 10.72, with lowest being ‒0.60 and highest found to be 24.00. The use of cast nets fishing gear is profitable.
