Sex composition of the fringe scale sardine, Sardinella fimbriata (Cuvier and Valenciennes, 1847) from Karwar waters, Karnataka


Author(s): RG Kudale, JL Rathod

Abstract: Sex composition of fringe scale sardine Sardinella fimbriata (Cuvier and Valenciennes, 1847) has been studied from Karwar waters, Karnataka. Sex ratio was calculated for different months and size groups of the fish were tested by using Chi-square (X2) test. The ratio for different months and size groups of males to females was found to be 0.97: 1.02 and 1.02: 1.03 respectively. The test of significance revealed that in January, August and December 2012 proportion of males and females varied, X2= 3.2 = 4.642, X2= 4.9 = 1.064 and X2= 3.36 = 3.665 (P<0.05) respectively. The Chi-square test for pooled data did not show any significant variation (X2= 1.64 = 0.148, P<0.05). An attempt has been made to study the sex composition of Sardinella fimbriata; these findings will help to predict the yield and exploitation of these fish from Karwar waters.
