Abstract

The activity of small pelagic fish is influenced by light, so changes in the moon phase will impact the distribution of fish, especially small pelagic fish. Therefore, this research aims to determine the concentration of fish based on lunar phases and explain the composition and frequency of fishing based on lunar phases in Bulukumba Regency. This research aims to provide information to fishermen to determine potential fishing areas. Data was collected in Bulukumba from July to September 2020 following 28 fishing trips using purse seines. The data used are primary and secondary. Primary data consists of the type and number of catches grouped based on lunar phases, namely dark, dark-to-light, light, and light-to-dark periods. Secondary data was obtained from interviews and literature studies. The data analysis used calculates the composition and frequency of catches. The results showed that there were eight types of fish caught during the research. The types of fish most commonly seen are trevally (Decapterus spp), yellow trevally (Selaroides sp), and mackerel (Rastrelliger spp). The highest catch frequency of these three types of fish occurred during the light-dark and light-dark periods.

Abstract

Purse seine productivity is related to the ability of fishing gear to catch fish that are clustered in the waters and the distribution of pelagic fish in the waters depends on changes in the moon phases that occur. Thus, this research aims to determine the productivity of fishing using purse seines based on changes in lunar phases in Bulukumba Regency. This research was conducted in Bulukumba Regency from July to September 2020. Data was collected by participating in 28 direct fishing trips. The research data used is primary data, namely the type and number of catches grouped based on lunar phases, namely dark, dark to light, light and light to dark periods. Secondary data used are the results of interviews with fishermen and literature studies. The research results showed that there were eight types of fish species caught during the research (scad, mackerel, yellowstripe trevally, frigate tuna, pinkear emperor, barred garfish, rainbow runner, and squid). The three dominant fish caught in each lunar phase were scad (Decapterus spp) with a total of 2.582 kgs, mackerel (Rastrelliger sp) total 1.651 kgs, and yellowstripe trevally (Selaroides sp) total 1.476 kgs. The highest productivity occurred in the second haul during the dark moon period at 0.64 kg/minute and there were no real differences in catch based on moon phase.
