Growth parameters of Channa striata in Musi River, Bengkulu and South Sumatra Province

Abstract

Due to the demand for striped snakeheads (Channa striata) as raw material for making exceptional Palembang foods such as corkscrews, fish cake “Pempek”, and crackers, the rate of exploitation becoming high and triggering continuous fishing by the fishermen. Information connected to the stock of striped snakehead is not widely known. This research intends to examine the growth parameters of striped snakehead. The research was held in March, April, June to September 2018 in the Musi River, South Sumatra Province. Fish tackle, including different-sized gill nets and nets, was used to gather fish samples from fishermen. The information acquired includes the rate of exploitation, the rate of mortality from natural or fishingrelated causes, and the rate of total mortality. The calculation results show the rate of total mortality (Z) = 0.95, the rate of natural mortality (M) = 0.67, death due to capture (F) = 0.28, and the rate of exploitation (E) = 0.29 every year.
