First report of laboratory reared developmental stages of Palaemon sewelli (KEMP, 1925) (Crustacea: Caridea: Palaemonidae: Palaemonidae)

Abstract

The ovigerous female of Palaemon sewelli (Kemp, 1925) was collected from Korangi Creek (Karachi, Pakistan) and kept in the laboratory. The larvae hatched after 7 days and survived until Zoea IV within 5 days at room temperature 29 °C-31 °C in filtered seawater with a salinity of 35-37 parts per thousand and a pH of 7.5-7.9. In order to feed the larvae, Artemia nauplii was used. The larval developmental stages are described, illustrated and compared with those of its congener’s larvae known previously.
