  Distribution, abundance, length-weight relationships of the African giant prawn (Macrobrachium Vollenhovenii) in River Osun was studied. Four hundred and fifty (450) samples were collected at 45 per week for 10 weeks between April and June 2016, at two different landing sites (Atan and Asejire Lake). Morphometric analysis showed that the prawn exhibited positive allometric growth (L-W) with regression equation “b” values of 4.869, 6.627 and 6.205 in Atan, Asejire and pooled samples respectively. The correlation between L-W was high; r=0.580, 0.834 and 0.752 in Atan, Asejire and pooled samples respectively (p<0.05). The sex ratio of M. vollenhovenii examined showed female dominance over male with ratio of 1.57:1.00 in Atan, 1.78:1.00 in Asejire and 1.74:1.00 in pooled samples. The rostral spines on the dorsal side of M. vollenhovenii observed r.. View More»
