AbstractThe spawning patterns of two penaeid prawns, Metapenaeus endeavouri (Schmitt) and M. ensis (De Haan), were examined from data collected at 45 stations between March 1986 and March 1992. An index of population fecundity based on the abundance, proportion and fecundity of sexually mature females was used as a measure of spawning output of the prawn stock. The population fecundity index for M...
An index of population fecundity based on the abundance and fecundity of spawners was used to describe spawning patterns. The effective spawning periods for stock renewal are spring (August to November) and late summer (January-February). Both the absolute and relative sizes of the seasonal peaks varied between years. Population fecundity was found to be a function of the complex interactions of...
