ANALYSIS OF THE RELATIONSHIP BETWEEN CHLOROPHYLL-a VALUES AND FISHERY CATCH IN KUALA SAMBOJA, KUTAI KARTANEGARA, EAST KALIMANTAN

Abstract

Kuala Samboja is located in an area adjacent to the Makassar Strait so it has a high fertility rate and most of the people make a living as The fishing gear used by fishermen to catch shrimp and fish is a trawler. This study aims to identify the type of catch, determine the main catch and bycatch by comparing the chlorophyll value in the waters of the catchment location. The method used in this research is a survey method, namely taking fishermen's catches and analyzing the chemical and physical results of the waters. The results of this study showed that the main catch values obtained were 8 types of shrimp, namely Penaeus monodon, Penaeus sp, Penaeus merguiensis, Metapenaus affinis, Metapenaus monoceros, Metapenaeopsis palmenis, Metapenaeopsis barbata and Solenocera crassicornis. The by-catch are fish, cuttlefish and squid. The number of catches that were mostly found at station 1 was 7030 ind, station 2 was 5885 ind and at station 3 was 5272 ind, while the catch was mostly found at station 3, which was 388 ind. The value of the main catch is very important with chlorophyll analysis in the catchment area, namely the largest chlorophyll value is obtained at station 1 which is 0.0973 mg/L, station 2 is 0.0869 mg/L and station 3 is 0.0759 mg/L. The results of this study indicate that the correlation value of R 0.87 between the number of catches and the value of chlorophyll in the waters has a positive effect.
