- ItemFecundity Studies on Sand Whiting, Sillago sihama (Forskal) from Karwar Waters(Society of Fisheries Technologists (India)Cochin, 1993) Reddy, C.R; Neelakantan, BFecundity indices were estimated in order to find the trends in fecundity with increase in length and weight of spawners. The different indices calculated were relative fecundity (Bagenal, 1957, De Silva, 1973), number of ova per gram ovary weight, coefficient of maturity (Nikolsky, 1961) and gonosomatic index. The number of ova per gram weight of fish varied from 287 to 587 with a mean value of 442, while the number of ova per gram ovary weightranged between 3533 and 7659 with 6120 as average. The coefficient of maturity values were found to vary from 5.72 to 9.07 (average 735) and gonosomatic index from 6.07 to 9.98 (average 7.95).
