Temporal Comparison of Native and Introduced Fish Catches of Cirata and Jatiluhur Reservoir In 2021-2023

ABSTRACT   

The management of capture fisheries in Purwakarta Reservoir, including Cirata and Jatiluhur Reservoir through the identification of catch weights between native and introduced fish, is one indicator of whether the environment is ecologically stressed or not. The method used in this study is a comparative descriptive analysis between secondary data obtained from the Purwakarta District Fisheries and Livestock Service and previous studies in Jatiluhur Reservoir. The highest catch was in 2022 with a value of 1305.98 tons, followed by 2023 with a value of 1235.03 tons, and finally 2021 with 1186.152 tons. There are four native fish species still caught in Jatiluhur Reservoir, with a weight ratio of 8% for native fish and 92% for introduced fish in 2023. In 2022, the weight ratio of native fish was 5% compared to 95%, while in 2023, the ratio of native fish to introduced fish was around 6% and 94%. The data about fishing gear shows a consistent reliance on gillnets and fishing rods over the three years, with a notable decline in fishing rod usage by 2023. The slight increase in boat usage from 2021 to 2022 and its stabilization in 2023 suggests a shift toward more mechanized fishing methods.
