Larval Development of the Blue Shrimp Penaeus stylirostris stimpson Reared in the Laboratory

Abstract

Artificially matured females of the blue shrimp Penaeus stylirostris stimpson were induced to spawn in the laboratory. The larval development was studied and compared with earlier studies on this species and with that of the brown shrimp P. californiensis which is similarly distributed in the Gulf of California, Comparison with earlier descriptions of this species reveals differences in morphological characters and in the number of moulting times during the naupliar stages. Comparison with the brown shrimp reveals the close similarities in the larval development of both species. The larvae of P. stylirostris reach the first postlarva passing through 6 naupliar, 3 protozoeal and 3 mysis stages as in the brown shrimp. © 1986, The Japanese Society of Fisheries Science.
