Abstract
Based on tlie modes of ova, 12 progressive stages are identified in the maturationof ovaries of king seer. A line, 3 standard errors above the regression of
Gonad Index on total length of fish in resting or immatures stages, L (G.I. =
—0.195 + 0.002046 L), is found useful in the separation of spawning flsh from
nonspawning fish. Estimation of maturity on the basis of the regression of maximum
ova diameter (m.o.d.) on G.t. holds only up to a G.I. of 7.2, beyond which
m.o.d. is in the range of 34 to 47 m.d. (1 m.d. = 0.0167 mm) irrespective of G.I.
The length at first maturity (701-800 mm or the median 750 mm) shows considerable
agreement with the values reported for the Papua New Guinea and
East African regions.
