    Reproductive Biology of Trichogaster pectoralis From Flood Plane captured in the Tangkerang Barat District and Delima District
    (2013-07-23) Oktafia, Dhela
    Trichogaster pectoralis (Anabantidae) is a type of fish that commonly inhabit flood plane of rivers in Riau and it is known as ornamental fish. The biological aspects of this fish, however, is poorly known. To understand the reproductive biology of this fish, a research study has been conducted on Februari to April 2013. Fish samples were captured from flood plane area of the Tangkerang Barat District and Delima District. Parameters measured were sex ratio, GSI, maturity level, fecundity, and egg diameter. There were 87 fishes (32 male and 55 female). The ratio of male and female was 1:2. The GSI of the fish was 0,07-9,58%, egg diameter was relative small (0,48-0,51 mm). The fecundity of fish from the flood plane was3341-22692eggs/ fish. During the sampling period, the maturity level of the fish captured was various, indicate that the T. pectoralis spawning period is relatively long and it peaks in Februari. It is predicted that the T. pectoralis is a parsial spawner.

    STUDI KOMPARATIF ASPEK BIOLOGI REPRODUKSI IKAN SEPAT MUTIARA (Trichogaster leeri) DARI RAWA BANJIRAN SUNGAI TAPUNG DAN WADUK FAPERIKA UR (Comparative Study of Reproductive Biology of Trichogaster leeri From Flood Plane captured in the Tapung River and FAPERIKA Dam)

    Trichogaster leeri (Anabantidae) is a type of fish that commonly inhabit flood plane of rivers in Riau and it is known as ornamental fish. The biological aspects of this fish, however, is poorly known. To understand the reproductive biology of this fish, a research study has been conducted on April to July 2012. Fish samples were captured from flood plane area of the Tapung River and from the FAPERIKA dam. Parameters measured were sex ratio, GSI, maturity level, fecundity, and egg diameter. There were 26 fishes (7 male and 19 female) captured in the FAPERIKA dam and 51 fishes (16 male and 35 female) captured from the flood plane. The ratio of male and female was 1:2,7 (in the dam) and 1:2,2 (in the flood plane). The GSI of the fish was 1-6%, egg diameter was relative small (0,6 mm). The fecundity of fish from the flood plane was 1.324-1.590 eggs/ fish, while that of the dam was 627-1.554 eggs/ fish. During the sampling period, the maturity level of the fish captured was various, indicate that the T. leeri spawning period is relatively long and it peaks in July. It is predicted that the T. leeri is a multiple spawner.
