Abstract: Length-weight relationship was studied in Liza parsia collected from the Champakkara region of Cochin estuary during the year 2009. Slope value (b) estimated for Liza parsia male was found to be 3.1545, for female 3.0094 and for combined was 3.1938. The regression equation calculated for male was Log W = -2.2147 + 3.1545 Log L, for female was Log W = -2.0315 + 3.0094 Log L and for combined was Log W = -2.2596 + 3.1938 Log L. Length weight relationship and condition factor showed that the growth of L. parsia is quite satisfactory. Morphometric measurements of various body parts and meristic counts were recorded. There is no change in meristic counts in increase in body length. Thus from the study it could be inferred that, Liza parsia showed a satisfactory growth in the Cochin estuary.
