Exploitation of striped snakehead (Channa striata) in Sempor Reservoir, Central Java, Indonesia: A proposed conservation strategy

Abstract. Setyaningrum N, Lestari W, Krismono, Nuryanto A. 2022. Exploitation of striped snakehead (Channa striata) in Sempor Reservoir, Central Java, Indonesia: A proposed conservation strategy. Biodiversitas 23: 3584-3592. Striped has important economic value freshwater systems, including Reservoir Indonesia, where increases catch sizes have resulted a declining population. In this study, we determined its population size based on abundance and distribution length assessed the rate exploitation estimated growth mortality rates to determine strategy Reservoir. The study was undertaken from March October 2020. method used purposive random sampling survey. Fish samples were taken five stations with different land uses. growth, mortality, analyzed by Pauly's model using FISAT II. Channa striata data Kruskal-Wallis test. results showed that highest C. at KW station almost three times higher than BK station. average gonads first maturity 277.4 mm females 284 males. parameters indicated an asymptotic (L?) 409.5 mm. An 0.74 classified as overfishing. is limit number catches much 44% prohibit catching individuals 230-349 Kedungwringin Station defined reference area largest complete distribution, namely, pre-reproduction, reproduction, post-reproduction stages. Bangkong spawning ground because there many fish reproductive stage River nursery mostly juvenile fish. These two sites must be protected for sustainable populations river reservoir.
