Abstract

The present investigation was conducted to work out linear regression relationships among six parameters scale length (TLS), scale width (WDS), number of ctenii found in horizontal (HRS)and vertical rows (VRS) on the scale, total radii counts (RDS), the vertical distance between focus and outer posterior edge of scale (Rs) in four commercially important mugilid species viz., Liza melinoptera, Liza macrolepis, Valamugil speigleri and Mugil cephalus)of family Mugilidae. The obtained results revealed that the most correlations between scale length (TLS) or width (WDS) with the selected scale parameters (HRS, VRS & Rs) were found to be weak (r < 0.50) and highly significant at 5% level (t-test; p < 0.05). Thus, the present study adopted to focus the implication of some functional scale characters that could be used as valuable alternative tools in observing the systematic relationship between different genera or species or geographical variants of family Mugilidae.
