Breeding biology of Megalops cyprinoides from Visakhapatnam coast.
Studies on stages of maturity, gonado-somatic indices and breeding cycle from two different habitats viz., the polluted Harbour Waters and the unpolluted Yerragedda Mouth revealed that M. cyprinoides breeds twice a year i.e., during Jan-Jul and Dec-Jan. Size at first maturity was 18 cm. in females and 19 cm. in males at both the stations. Sex ratio was 1:1 at the polluted station and 1:1.1 at the unpolluted station indicating a slight domination of females.
