PEMATANGAN GONAD CALON INDUK IKAN SEPAT MUTIARA (Trichogaster leeri Blkr) DALAM KERAMBA DENGAN PADAT TEBAR BERBEDA

Abstract

This study aims to determine the best stocking solid in the gonad maturation of Tricho-gaster leeri Blkr in cages placed in ponds. Cage size used is 1 x 1 x 1 m were placed in thepond Fisheries and Marine Science Faculty, Riau University with a solid stocking respectivelyP1 = 30 fishes/cage, P2 = 40 fishes/cage and P3 = 50 fishes /cage. The fish were reared for 6(six) weeks, during maturation of fish feed shrimp pellets + vitamin E. Maturation observa-tions conducted each week by taking 20% of the samples. Parameters measured were maturitylevel, gonado somatic index (GSI), fecundity, egg diameter, semen volume, and mortality.The results showed that the best treatment was P1 = 30 fishes/cage produce attainment gonadmaturation (TKG IV) was 2 fishes, gonado somatic index (GSI) was 8.36 %, fecundity was1004 eggs, egg diameters was 0.66 mm, semen volume was 0.0173 ml and mortality was 2fishes.]
