The ...The sex ratio & Gonadosomatic index of sind sardine, Sardinella sindensis (Day, 1878) of Karachi coast, Pakistan were investigated. Sardinella sindensis had sex ratio of 1: 1.25 (male to female). The difference in sex ratio was not significantly different (p > 0.05) from the expected theoretically 1: 1 distribution except April 2002. The highest Gonadosomatic index value in males during June August were 3.813 to 4.078, while in females the high values during June August were found to be 3.157 to 5.616, which suggested the spawning period. The highest GSI value in males were 2.548 to 2.711 in size groups of 170 199Mm and the lowest GSI value were 0.627 0.746 recorded in 110 129Mm, while in females at high values were 3.769 to 4.550 in 180 209 Mm Size groups and the lowest GSI values were 0.686 to 1.064 in 100 139 Mm size groups. The results will increase our knowledge of reproductive biology of Sardinella sindensis which is relevant for fisheries and aquaculture management as well as breeding programmes.Read More
