LWRs (length-weight relationships) are a useful method for evaluating stock biomass in fisheries. The b parameter from LWR setup also provides data on the growth pattern of fish in a certain place or habitat. The LWR data may then be used to estimate fish conditions. As a result, the goal of this research is to estimate the LWR and condition indices of reef fishes in order to identify growth patterns and fish conditions, which are critical pieces of information for any fishery. During the sample period, the reef fish caught in bobo fish traps were identified and subjected to length-weight relationship analysis as well as the creation of condition indices. The data found that bobo fish traps were linked to 16 species in the research region, divided into nine categories. The length-weight relationship for fourteen species revealed that they all grew allometrically, with ten (10) species achieving negative allometric growths and the remaining four achieving positive allometric growths, indicating that the majority of the fish become less round or slender as they grow in length. The condition index (relative weight) of the ten species investigated in this study was more than 100%, indicating that they acquired more weight than the observed population. Based on these findings, it was found that just a few reef fish species in the area were linked to the bobo fishing method. The majority of the species had negative allometric growths, indicating that the specimens are likely to face food shortages. Regardless of possible challenges to food resources, the findings of the condition index study may indicate that the fishes' environment is generally healthy. The confounding conclusion, however, demonstrates the difficult-to-extrapolate, complex interplay of fish development with environmental changes.
