Developmental Stages of Trachypenaeus Curvirostris (Stimpson, 1860) (Decapoda, Penaeidae) Reared in the Laboratory

Abstract

[The embryonic and post-embryonic development of Trachypenaeus curvirostris were observed in the laboratory. The eggs hatched as first nauplii after about 15 hours at 25.8°-26.2°C and 32.5 g kg-1 salinity. The larvae were fed only with Chaetoceros gracilis and Tetraselmis tetrathele until early postlarval stage. Six naupliar, three protozoeal, three mysis, and one post-larval stages were described and illustrated in detail. The larval morphological characteristics were compared with those of other species of Trachypenaeus, Metapenaeopsis and Penaeus., The embryonic and post-embryonic development of Trachypenaeus curvirostris were observed in the laboratory.
