Description | ||||||
A total of 300 female freshwater prawns Macrobrachium malcolmsonii were sampled from April 2004 to December 2005. The breeding season of the female prawn was observed to be from April to August and peak in April to June. Five stages of ovarian development were oogonia (white), previtellogenesis (pale yellow), early vitellogenesis (yellow), vitellogenesis (green), and vitellogenesis (deep green) were recorded. The Gondosomatic Index GSI values were correspondence with ovarian development and cell diameter. The (GSI) value of the prawn was inversely related to the Hepatosomatic Index (HSI) value. In fecundity, the total number of eggs ranged from 1170 to 30104 eggs were observed. The condition factor of the female prawn was the highest in April (1.3 r 0.002). It can be concluded that the breeding season of M.malcolmsonii was observed from April to August according to GSI values of female prawns. Five stages of ovarian development of Macrobrachium malcolmsonii were observed in this study. |
