Kamburupitiya, 1998) Nathanael, S.Comparisons were made on the length weight relationships, fecundity and egg diameter distribution of yolked ova in mature ovaries of pond cultured female common carp with those collected during the same period from the Victoria reservoir. Irrespective of the location, the condition factor of gravid females was within the range 1.6-2.0. However, the average body condition of ripe females from the reservoir was better than those from the pond. Yolked ova in ripe (Stage vi) ovaries had a diameter between 0.85 to 1.70 mm. The single mode indicates that the ova ripen simultaneously and are shed in a single batch. Fecundity is linearly related to body and gonad weight, and curvilinearly to body length. Fecundity of pond cultured females with a length of 30.8 to 46.0 cm had a fecundity between 49, 070 and 240, 100 Irrespective of the location, the fecundity of females within the same length group were within the same range. The presence of larger sized females with a correspondingly high fecundity and good body condition which produce heavily yoilked eggs indicated that under the prevailing conditions, there is potential for the establishement of a common carp based fishery in large , deep reservoirs like the Victoria, Development of pond culture to re-stock heavily depleted reservoirs with fingerlings is therefore feasible.Item Mating behavior in honey bees (Genus Apis)(Faculty of Agriculture University of Ruhuna.
