M. M. Thomas, M. Kathirvel and N. N. Pillai

Informations on egg, naupliar and protozoeal stages of Parapenaeopsis acclivirostris (Alcock) are given for the first time as the result of the spawning of the species in the laboratory. The spawning took place in the midnight and the naupliur I emerged at 08.00 hrs next day morning. Within 30 hrs after spawning fifth naupliar stage was attained and the larvae reached Protozoea III in 173 hrs. Eggs, five naupliar and three protozoeal stages are described and illustrated in detail. A comparative study of these stages with those of P. stylifera is also presented.
