✦ Synopsis

Some aspects of the maturation and spawning of the commercially important prawns of the Arabian Gulf, Penaeus semisulcatus de Haan, Metapenaeus stebbingi Nobili and Trachypenaeus granulosus (Haswell), have been studied. Five maturity stages: immature, early maturing, late maturing, mature, and spent-recovering, are distinguished, and the maturation process in the female of each species is described. The minimum size at first maturity was estimated to be 126 mm for P. semisulcatus, 88 ~ for M. stebbingi and 64 mm for T. granulosus. T. granulosus breeds throughout the year, with peaks in June, November-December, and in April; in P. semisulcatus and M. stebbingi the breeding period extends over the period October to March or April.
