Length-weight relationship, condition factor and relative condition factor of Macrobrachium rosenbergii in rice fields.

摘要

To determine the length-weight relationship of Macrobrachium rosenbergii a total of 100 shrimps were collected from the experimental plots of integrated rice fish/shrimp culture which was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh from 2nd August to 30th November, 2003. Standard length-weight relationship of Macrobrachium rosenbergii was obtained: Log W=-2.0518341+3.07513132 Log L. The co-efficient of correlation (r) was 0.99 which showed strong and highly significant relationships between length and weight. The mean values of condition factor (K) and relative condition factor (Kn) were 1.0893674 and 1.0012671, respectively, which suggest good condition of the prawn in rice fields.
