Laju Pertumbuhan Dan Mortalitas Ikan Selais (Ompok Hypophthalmus) Di Perairan Sungai Indragiri Desa Lubuk Terentang Kecamatan Gunung Toar Kabupaten Kuantan Singingi Provinsi Riau

---

ABSTRACT
Ompok hypophthalmus is one of the caught fish commonly found in the
Indragiri River, Lubuk Terentang Village. The purpose of this study was to determine
the rate of growth and mortality of Ompok hypophthalmus. Fish sampling was carried
out for 10 days in February and 10 days in March by using drift nets and nets. Data
were analyzed by ELEFAN I method, FiSAT II software (FAO-ICLARM Fish Stock
Assessment Tool). There were 109 fish caught. The results showed that the growth
pattern of fish was negative allometric. Long frequency distribution ranges from 150
to 261 mm. The results of the Von Bertalanffy growth equation show that Lt = 260.40
(1-e-1,2(t+0.073)). This means the asymptote length (L∞) of the hypophthalmic is
260.40, the growth coefficient (K) 1.2 per year and the theoretical age (t0) of fish is
equal to 0.073. The total mortality (Z) of fish is 1.88 per year. The estimated natural
mortality (M) of fish is 1.09 per year and deaths due to capture (F) of 0.79 per year.
The exploitation rate (E) of fish is 0.42 and shows this value is still below the
optimum exploitation rate of 0.50.
