Abstract

Growth and production characteristics of Macrobrachium rosenbergii stocked at
two densities were examined. Prawn juveniles (0.78±0.54 g) were reared for 180
days in 0.0014 ha tanks at two stocking densities (5/m2 and 10/m2) individually.
The culture tanks were manured with cowdung and inorganic fertilizers and a
supplementary feed of 22% crude protein was given to the prawns. The results
indicated that at low stocking density (5/m2) the growth and survival were higher.
Prawns attained a final mean body weight of 31.32±21.5 g and 28.38±14.23 g in
low and higher stocking densities, respectively. The estimated productions were
984.34 and 1,662.26 kg/ha per crop, respectively for two stocking densities. Higher
mean growth rate, specific growth rate and low FCR were witnessed only in the
low stocking density. The relationship between growth and days of culture is
significant (P<0.05) in the two stocking densities but, the difference between
growth rates of the prawn at the two densities tried is non-significant (P>0.05).
Advantages of low stocking are witnessed with reference to individual body weight
at the harvest.
