Abstract

Ova-diameter frequencies indicate that the spawning period in 5. tumbil is
protracted, extending from October to Marcti, with the peak in November-
December and that the eggs are shed in 5 or 6 batches. The minimum size at
first maturity and size at 50% maturity in female have found to be 260 and
300 nun in total length, respectively. The fecundity estimates ranged from 37,569
to 2,14,981 eggs in the size range 290-430 mm. Ova counts per gram of the
ovary were calculated for estimating the number of eggs spawned in different
batches. A plot of fecundity values against length showed an exponential relationship
of the form, F = AL while the relationship between the fecundity and
weight of fish is expressed by a linear regression equation of the form Y = A + BX.
The available data indicates that the spawning and maturation in S. undosquamis
may be similiar to that of S. tumbil The differences between specimens of S.
tumbil. from Waltair, Mangalore and the East China and Yellow seas in respect
of the size of the ova, spawning period and other characters are given
