The earliest reference to the fecundity of the Indian mackerel was by Devanesan
and John (1940) who estimated the number of ripe eggs in the mackerel ovary as
94,000. Subsequent work was directed mostly towards finding out the spawning
behaviour of this fish, by the study of the intra-ovarian eggs. Pradhan (1956)
indicated the possibility of the Indian mackerel spawning the eggs in successive batches
over a prolonged period, like its Atlantic counter-part Scomber scombrus (L). Pradhan
and Palekar (1956) described the maturity stages I to VII, based on the external
appearance of the ovary, its size relative to the abdominal cavity, and the range of
ova-diameter readings. However, they have not given any ova-diameter frequency
polygons.
