HUBUNGAN PANJANG BOBOT DAN FAKTOR KONDISI IKAN ENDEMIK PIRIK (Lagusia micracanthus, Bleeker 1860) DI SUNGAI SANREGO, SULAWESI SELATAN

Abstract

This research aimed to study correlation between the weight length and the condition factor of Pirik

fish.The sample collection conducted from September 2014 through February 2015 in Sanrego river, Langi

Village, Bone regency, South Sulawesi. The analysis of the samples carried out in the Laboratory of Fish

Biology, Department of Fisheries, Hasanuddin University, Makassar. The total length was measured using

digital calliper of 0.01 mm and the weight was measured using the digital scale of 0.001 g. The fish samples

were dissected and categorized into male and females with the sex gonad maturity. The total samples of the

endemic pirik fish collected during the research were 162, 72 male dan 90 female fish. The correlation of the

weight length was based on the equation W=0,00003L2,8719 at male fish, W=0,00003L2,8575 in the female fish and

in general, the obtained equation was W=0,00003L2,8846. The result of the t test showed that the value was

higher than t table; therefore, the Pirik fish in Sanrego rivers had negative allometric growth attern (minor) (b <

3), since the addition of body length was faster than the increase of body weight. The analysis of the condition

factor revelead that the value range of 0,8038-1,2926 with an average 1,0274 in male fish and 0,9263-1,4533

with the average of 1,1598 in female fish. This showed that the conditions factors of the endemic pirik fish were

lower compared to the female fish.
