Analisis Pertumbuhan Dan Laju Ekploitasi Ikan Kurau (Eleutheronema Tetradactylum) Di Perairan Bengkalis Yang Didaratkan Di Tpi Desa Meskom Kecamatan Bengkalis Kabupaten Bengkalis
ABSTRACT
Eleutheronema tetradactylum is an important economic valued fish in the
Bengkalis waters. Due to the high demand of consumers, the fish is highly
exploited and it negatively affects the fish population. This study was done in the
Bengkalis waters on May to July 2020 and purposed to understand the length
frequency distribution, determine the growth parameters, mortality rate and the
rate of exploitation in order to provide appropriate management model for that
fish resource. Data were analysis by a ELEFAN I method (Electronic Lenght
Frequencys Assesment Tool) from the FISAT II (FAO-ICLARM Fish Stock
Assesment Tool) software. E. tetradactylum captured were 78 samples, the length
frequency distribution of the female fish were ranged from 75 to 154 cm TL. The
growth pattern of the fish was allometric negative. The Von Bertalanffy growth
equation shown that the coefficient (K) 1.01 with infinitive length (Lā) 151.2 cm
and t0 -0.2115 per year. The total mortality rate (Z) of the fish was 3.43 per year
at the rate of natural mortality (M) 1.14 per year, while mortality rate due to
fishing (F) 2.30 per year and the exploitation rate was 0.67 per year. The value of
the exploitation rate has exceeded the value of the optimum exploitation that was
0.5.
