Aspek Pertumbuhan Ikan Cucut yang Didaratkan di Pelabuhan Karangsong, Kabupaten Indramayu, Jawa Barat

Abstract

This study of shark growth held in Karangsong’s port, Indramayu, West Java. The research was began in June to August 2012. Morphometric measure taken from the all sharks which landed in that port during research. There was 3 order, 5 family and 10 species of shark’s recorded but only 2 dominant species had become the main study, it was Carcarhinus dussumieri and Chiloscyllium punctatum. Both of this species had length between 60-100 cm. Growth coefficient (K), asymptotic length (L∞), and age when fish length is theoriticaly 0 (t0) for C. dussumieri is 0.63, 97.44, and -0.18, and C. punctatum 0.32, 90.40, and -0.38. This differences caused by different of its reproduction type, which C. dussumieri gave birth of its pup and C. punctatum laying its egg in seafloor. Sex ratio of these two sharks is equal both male and female (1:1), so we can assumed that there is no sexual segregation both of this species. Recommendation for the management is with limiting output quantities such control the limit of sharkfin export.
