Impact of the climate on fishing locations of fish Larvae in Palabuhanratu bay

Abstract

Abstract The phenomenon of climate change influences primary production, food chain interactions, and distribution of fisheries species. Sukabumi Regency, especially Palabuhanratu Bay, is a fishing ground for fish larvae. Fish larvae are an essential phase in supporting the existence of fish resources. The study aims to determine the spatial distribution of fish larvae locations in Palabuhanratu Bay and analyze the relationship between the phenomenon of climate change and fish larvae locations. The variables are rainfall, salinity, sea surface temperature, currents, and tides. The phenomenon of climate change using rainfall data years 2000-2019, Landsat 5 TM and Landsat 8 OLI/TIRS. Salinity estimation generated from Landsat 5 TM and Landsat 8 OLI/TIRS using the Cimandiri Algorithm. The Split-Window Algorithm with the sea surface temperature value. The results found fishing larvae located around the estuary and the beach towards the sea along the Palabuhanratu Bay. The biggest catches from these fish larvae are in Cimandiri estuary and Citepus estuary. This research concluded that rainfall affects the catches of fish larvae because it is directly related to the oceanographic condition of the bay waters.
