This method of fishing is associated with reef fishes. Reef fishes caught by this method were identified and subjected to length-weight relationship and condition index. Physical dimension of the traps and the pattern of fishing were determined.
Results revealed that there were 60 species belonging to 21 families associated with bobo fishing method in the said site. The establishment of length-weight relationship for 40 species indicated that most of these fishes grew allometrically negative which gave the implication that growth rate in weight decreased as the fish grows in length. Moreover,condition index indicated that most of them attained lesser weight compared with other geographically isolated populations.
Based on these findings, it has been concluded that many species of reef fishes were associated with bobo fishing method. Having negative allometric growth implied that adult specimens face nutritional inadequacy than smaller ones which may be brought by certain factors. The lesser attainment of weight also implied that certain factors affect the well-being of reef fishes in the site such as environment degradation. Furthermore, it was recommended that more extensive studies regarding LWR shall be conducted, incorporating several important variables such as sex and season, geographical and time influences and more extrinsic taxonomical examinations.
