Ghory Quddusi B. Kazmi http://www.iaees.org/publications/journals/arthropods/articles/2026-15(1)/developmental-stages-of-Palaemon-semmelinkii.pdf> The ovigerous female of Palaemon semmelinkii (de Man, 1881) was collected from Ambro Creek (Lat. 24 o34'9''N Long. 67 o60'8'') and kept in the laboratory. The larvae hatched after 5 days and survived until zoea II at room temperature 25 oC-29 oC 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 recognized previously.
