Abstract
Breeding biology of Valatnugil cunnesius (Val.)/ inhabiting the Ashtamudi estuary
along the southwest coast of India, was studied in detail. Sixmaturity stages viz., immature,
maturing-I, maturing-II, mature, oozing and spent were identified. Relatively higher
Gonado-somatic indices were observed during July to December. Results revealed that
V. cunnesius in the Ashtamudi waters has a prolonged spawning season which extends from
July to December. The size at first maturity for males is around 139 mm and for females
around 148 mm (total length). The sex-ratio of males to females was 1:1.5.
