Abstract

The present study attempts to develop a comprehensive length-weight relationship and relative condition factor (K_n) of Xenentodon cancila collected from River Mat in Mizoram. The value of exponent ‘n’ in the equation W = cLⁿ was 1.185 for the species X. cancila. The computed ‘t’ value indicated that the ‘n’ value of the species is significantly different from the expected value ‘3’ and hence the Cube Law W = cLⁿ did not hold good in the case of X. cancila found in Mat in Mizoram. The correlation co-efficient (r) in X. cancila was found to be 1 indicating that there is high positive correlation between length and weight in the species. The relative condition factor (Kn) remained greater than 1 for the species indicating their general well being to be good in Mat River in Mizoram.

Key words: Length-weight relationship (LWR), relative condition factor, Xenentodon cancila, Mat River, Mizoram.
