Abstract

Sero is a type of fishing gear whose operation is carried out around coastal waters, is permanent, and has the role of trapping fish that have territorial areas around the coast or fish that migrate towards the coast. The oceanographic conditions of a body of water can be used to indicate fishing areas for certain types of fish. This research aims to determine the influence of oceanographic factors (temperature, salinity, currents, and tides) on sero catches on Karampuang Island, Mamuju Regency, West Sulawesi. The research was carried out in June-July 2023 on Karampuang Island, District. Mamuju, West Sulawesi. This method uses a field survey method, namely measuring temperature, salinity, tides, and currents. The results of this study indicate that the influence of oceanographic parameters on the total sero catches yield together with the independent variables (X) does not have a significant impact on the sero catches yield (Y). Individually (partially), the variable with a negative value, the temperature on serocatch but not substantial.

Abstract

Coral reef ecosystems in coastal areas and on small islands, such as Samalona Island, play a vital role in fisheries and tourism. One method of coral reef conservation in Indonesia is the use of spider webs. This study aimed to analyze the survival and growth rate of coral reef transplants using the spider web method on Samalona Island from January to December 2024. Field data were obtained by measuring the length of coral fragments monthly. The results showed that coral seedling mortality was highest in the first quarter (27.05%) and lowest in the fourth quarter (1.44%). The highest growth rate was recorded in the fourth quarter (3.77 cm), with an average monthly growth rate of 0.88 cm.
