Mapping of fishing areas and the effect of the moon phase on trap net catches in Pangkep District Waters, Indonesia

Utilization of abundant resources in coastal areas is carried out by fishermen using various types of fishing gear, both traditional and modern. The study used a survey method, the data collected consisted of primary data and secondary data. Data were analyzed using geographic information system methods and ordinary statistical regression methods. The results showed that the trap net fishing grounds in the waters of the Sigeri District, Pangkep Regency, were available in several places and were ideal for operating trap nets. There was observed a significant effect of the moon phase (tidal) on fish catches during the operation of trap net fishing gear, especially in the full moon and dead moon phases, due to the high tides. Tidal height affected most of the amount of catch and only a small part was influenced by several external factors, during the study. For every 1% increase in sea level at high tide, the catch value increased by 1,329 g. The regression coefficient shows a positive value, meaning that the tidal height variable affects the catch.
