MORFOMETRIK DAN MERISTIK IKAN BUNTAL PISANG (Tetraodon lunaris) DI PERAIRAN LAUT DAN PAYAU KABUPATEN BENGKALIS

Abstract

There are two kinds of morfologi, morfometrics and meristic. Morfometrics is characteristics which are associated with part size of fish body such as the total and standart length. Meristics is characteristics which are connected to the number of body part of fish such as the number of scales on the lateral line, the number of hard and sof dorsal fins. Morfometrics and meristic study of puffer fish (Tetraodon lunaris) was conducted at Bengkalis and Sungai Pakning waters. The aim of this study is to know the differentes between of morfometrics and meristics of puffer fish in waters with different salinity condition. This study was conducted from September to November 2012. Fish sampling was carried was at Bengkalis and Sungai Pakning waters which has 50 samples for each location. Research data was analyzed using excel and SPSS program. The total length of puffer fish in Bengkalis and Sungai Pakning ranges 45-160 mm and 45-151 mm. Puffer fish growth status in the both locations of research is positive allometrik, negative allometrik and isometric. There are no differences in shown puffer fish morfometrics character ratio between Bengkalis and Sungai Pakning waters.The T- test result shows character growth JSAPSE / PT significantly different between both locations of this research. There are no differences in puffer fish meristics for both locations, Bengkalis and Sungai Pakning waters
