Abstract

The aim of this study was to determine a correlation between the length, width and weight of otoliths and the length and weight of fish samples of Amblypharyngodon mola (Hamilton,1822), a Rasborine fish caught from Middle Ganga region. Total length (TL) measurements were made with a 1mm precision fish length measuring scale. Image J software was used for measuring otolith length and width. This study shows strong correlation between fish length (TL), otolith length (OL) and width (OW), and similarly shows the correlation between Fish weight (TW) with otolith mass   (test, P<0.05).  According to this study, Otolith size depends on the fish length and fish weight and the regression coefficients between the relationship of fish length and fish weight with otolith measurements was found to be the best indicator for estimating the growth of fish.               

Key words: Amblypharyngodon mola, Rasborine fish, otolith morphometry.
