DOMINANT FISH GROWTH IN DIGOEL RIVER, EDERA DISTRICT, MAPPI REGENCY

This study aims to examine growth factors, namely the growth patterns of the dominant fish caught on the Digoel River, Edera District, Mappi Regency, by using a long-weight relationship index. This research was carried out from August to September 2017. The sample fish was obtained by stocking fishing gear, gill nets, fixed rawi, and spoon webs. The results of the study obtained dominant fish based on the number of catches namely species Parambassius gulliveri (141 tails), Kurtus gulliveri (100 tails) and Cinetodus crasslabris (97 tails). The pattern of fish growth is based on the catch of the three species of fish Parambassius gulliveri, Kurtus gulliveri and Cinetodus cassilabris are positive allometric which means that the weight gain is proportional to body length increase and the condition of fish conditions during the study is relatively small and is in the enlargement stage
