Shafiqul Islam Mohammad Abu Jafor Bapary 3200363Fecundity of 50 specimen of dhela Osteobrama cotio cotio was studied. The number of
eggs varied from 512 (total length 2.20 cm and body weight 1.12 g) to 6849 (total length
5.7 cm and body weight 7.1 g). The mean fecundity was 3273+1708 (mean body length
3.880+1.216 cm and mean body weight 3.667+1.82 g and gonad weight 0.605+0.302 g).
The fecundity was found to have a linear relation with body length, weight and gonad
weight of fish and all these relationships were highly significant. The maximum GSI
value (15.31) was found in the month of June, which indicated the period of maximum
gonadal growth. A sharp drop in the GSI value (3.79) took place in September indicated
the spawning occurred before September. However, the breeding season of dhela started
in the monsoon month of early June and extended until September.]]>Afroze, S. and M.A. Hossain,1990Amblypharyngodon mola (Ham.) (Cypriniformes: Cyprinidae).]]>91721Ali, M., A. Sabur, A.
