Biological Base of Skipjack as The Foundation for Sustainable Fisheries Management in The Flores Sea

Skipjack fishing in the Flores Sea using pole and line is conducted in FAD and non-FAD. Fishing in FAD areas is expected to optimize fishing activities without considering the level of utilization and sustainability of fish resources. This study aims to analyze the length-weight relationship of skipjack and describe the composition of catchable and noncatchable fish sizes in FAD and non-FAD areas. This research was conducted by following the pole and line fisheries operating in the Flores Sea from January to April 2025. Sampling was done by purposive sampling, which is taking samples that are considered to represent the size of the existing population. The number of fish samples amounted to 304 fish. The results showed that the value of b<3, this indicates that skipjack caught in Flores Sea waters has a negative allometric pattern. The length range between skipjack caught using FADs ranged from 29 - 60 cm with a catchable size of 27% and not catchable by 73%, while for the range of skipjack caught Non-FAD ranged from 27 - 66 cm with a catchable size of 22% and not catchable 78%.
