Abstract

Freshwater prawn (Macrobrachiumrosenbergii) in Bangka,is one of the important economic prawn.The sustainability of freshwater prawn is threatened by degradation of natural habitat. Information of reproductive aspect is needed for further management. The objective of this study was to examine fecundity of freshwater prawn. Based on the data, during sampling sex ratio showed that female freshwater prawnpopulation are greater than male population, which ratio Female: Male = 9:1. Berried female freshwater prawn found 5with mean value of fecundity was 11,808 ± 8,155. The mean value of Body Weight was 98.56 ± 74.29 gr and Total Length was 15.28 ± 3.18 cm. In general, physicochemical water parameters were ideal range for freshwater prawn to dwell. The mean values of temperature, pH value, turbidity and Dissolved Oxygen were 27.56 ± 1.02°C ; 5.56± 0.51 ; 39.66 ± 2.97; 3.09 ± 0.25respectively. The reproductive potential of freshwater prawn stock as well as an assessment on stock size of their natural population can be analyzed using the fecundity data
