Abstract
791 mackerel along the coast Karnataka during 1979-80 season was studied
for total length-eye diameter relationship. It was found that mackerel having the eye
diameter range 0.5 to 0.9 cm belong to 1 year old group, 1.0 to 1.2 cm to 2 year old
group and 1.3 to 1.5 cm to 3 year old group.
Among the many morphemetric characters, eye diameter of fish has attracted
little attention in the field of fishery research. When compared to other morphometric
characters, eye diameter seems to have no significant role to play in taxonomical work.
The present note aims in correlating the eye diameter of the Indian u ackerel R. kanagurta
to total length and hence to age of the fish.
