Fecundity in the spiny lobster Panulirus polyphagus (Herbst).

P. V. Kagwade

Ovigerous females of P. polyphagus were encountered in the landings throughout the year at Bombay forming about 25 to 30% of the females in the catch. The rate of production of eggs was very high and there appeared linear relationships between the size of a female and the number of eggs in a batch and also with the number of batches of eggs to be spawned in a year. The number of eggs spawned in a year at different ages and the number of batches involved in it were discussed. Annual egg productions of 1,43,000 and 47,23,000 were estimated for specimens of 180 mm and 353 mm in total length respectively.
