Abstract:
Present study was conducted on Frill fin goby (Bathygobius soporator) to provide information on its abundance, morphometric measurements and growth patterns in Badagry creek, Lagos, Nigeria. A total of 506 individuals were caught from the creek between January 2008 and January 2009. They were caught with gill nets and non-return barrier traps. Biometric and morphometric data were obtained from the fish. Abundance of the fish was in favour of low rainfall and high salinity. Four hundred and seventy males and five females were encountered in the study, giving 1 male: 0.0106 female ratio. The morphometric data included eye diameter, which varied between 3-9(4.98±0.43) mm, head length ranged from 16-60 (39.15±4.9) mm and body depth, 20-70 (27.15±4.46) mm. The fish measured between 60 and 252 (131.21±17.68) mm total length, weighing 2.7 and 291.9 g b.wt, respectively. The populations of the species showed variations in their morphometric measurements which were not differ significantly (p≥0.05), indicating that the fish population may not be genetically diversified. These insignificant variations may be related to the geography, ecology and human activities of the creek. The fingerlings measured between 60-99 mm TL; juveniles, 100-149 mm TL and adults, 150 to 252 mm TL, representing 18.58, 55.14 and 26.28% of the population, respectively. The LWR was Log W = Log-1.56+1.43 Log L (r = 0.66) representing a negative allometric growth relationship. The condition factor for the fish was less than 2.890 g cm-3. This study therefore provides information on the biologic aspects of B. soporator as baseline data for its ecology, management and conservation in Badagry creek.
