Description The catfishes, Arius caelatus and Arius thalassinus have been compared morphometrically
for seven characters with reference to fork length from Mumbai, Veraval, Vishakhapatnam and
Veraval coasts respectively. For Arius caelatus, significant differences were found between the
sexes at the same locality, within the same sexes at different localities and between both sexes
combined from Mumbai and Veraval four out of seven characters were investigated. Similarly,
for Arius thalassinus, significant differences were noticed between and within the sexes at the
same locality and when the sexes were combined, almost all the characters showed highly
significant differences between the Veraval and Vishakhapatnam populations, which have been
attributed to separation of stocks. The sex specific length weight relationships between the sexes
as well as locations were not significant for A. caelatus, hence a relation common to both sexes
and regions was established. But A. thalassinus showed highly significant differences, in respect
of sexes as well as locations. Therefore, separate relationships were obtained for sexes and
locations for the latter.
