Sei Carang waters are baronang fish habitat (Siganus guttatus). The research was to determine the length-weight correlationship and condition factors of baronang fish (S. guttatus) in Sei  Carang. Sampling of baronang fish (S. guttatus) in two months (September-Oktober 2019) is taken once a week based on fishing activities and water conditions. Length-weight correlationship of female and male baronang fish (S. guttatus) were W = 2,0895E-05L^2,9575 and W = 1,30073E-05L^3,0424 respectively, based on this value show that female and male baronang fish (S. guttatus) in Sei Carang have isometric growth patterns (b = 3). Condition factors of female and male baronang fish (S. guttatus) were 1,735 and 1,633 respectively.

Village Malang Rapat waters are have the potential and habitat of kurisi fish resources (Nemipterus sp.). The research was to determine the length-weight relationship of kurisi fish (Nemipterus sp.) in Village Malang Rapat. Sampling of kurisi fish (Nemipterus sp.) in two months (October-November 2020) is taken once a week based on fishing grounds and habitat. Length-weight relationship of female and male kurisi fish (Nemipterus sp.) were y = 1,1568x^2,0659 and y = 1,2123x^1,8971 respectively, based on this value show that female and male kurisi fish (Nemipterus sp.) in Village Malang Rapat waters have negative allometric growth patterns (b < 3).
