Abstract

Teleostean scale characteristics like length, width, number of circuli, primary
radii, secondary radii and ctenii were studied to delineate its relationship
with total length in a euryhaline fish, Oreochromis mossambicus (Perciformes:
Cichlidae). Statistical analysis proved a positive correlation between the scale
characteristics and fish size. The characteristics of midlateral scales indicated
that these scales appeared first during squamation chronology. Further
observations also indicated that differences in salinity could modify the
morphometries of scales.
Keywords : Fish scale morphometries, Oreochromis mossambicus, circuli,
radii, ctenii
