Length-weight relationship and condition factor of Macrobrachium rosenbergii (De Man, 1879) were investigated for
different culture phases, developmental stages and sexes in the present study. Regression lines differed among the culture
phases, developmental stages as well as between sexes. Significant difference in the slope was observed among different
culture phases with nursery animals showing significantly lower slope. The most significant variation in the slope was
observed among different developmental stages. Sex wise comparison also exhibit highly significant variation between male
and female. Therefore, separate interconversional equations were derived for different culture phases, developmental stages
and sexes to simplify management during culture. Additionally, condition factor was also found to be varying significantly
between different culture phases, developmental stages and between sexes.
