Penaeus semisulcatus, the green tiger prawn or grooved tiger prawn, is a commercially important species of prawn in the genus Penaeus.
Penaeus semisulcatus has a pale brown body which sometimes shows a greenish tint on the carapace with two yellow or cream tansvers bands across the back of the carapace. The abdomen is banded with brownish grey and pale yellow transverse bands, while the antennae are banded brown and yellow. It has a uniformly smooth carapace and abdomen. The rostrum has 7 or 8 dorsal teeth and 3 ventral teeth. The atrodrostral crest and groove, the carina, extends beyond the epigastral tooth with the post-rostral carina almost reaching to the rear of the carapace. The maximum total length is 180mm for males and 228mm for females, weighing up to 130g.
Penaeus semisulcatus has an Indo-West Pacific distribution being found from eastern Africa and the Red Sea east to Indonesia and northern Australia. It has also colonised the eastern Mediterranean through the Suez Canal making it a Lessepsian migrant.
Penaeus semisulcatus occurs from coastal waters down to 130m depth over sandy and muddy substrates. In the Persian Gulf P. semisculatus spawning was at its height during December and in March, but there was a secondary peak in autumn and 90% of the female prawns reached sexual maturity after attaining a carapace length of 54mm. Spawning takes place mainly offshore. The adults are marine but the juveniles prefer estuarine environments.
Penaeus semisulcatus is of minor to moderate importance in Madagascar, along the eastern coast of Africa and in the Red Sea. Along the south western Asian coasts from the Gulf of Aden to Pakistan theis species is of major importance to the offshore fishery. In India it is not as commercially important as Penaeus monodon. P.semisulcatisis is probably an economically important species in Sri Lanka, Singapore and the Philippines, as well as in Hong Kong, southern Sea of Japan and Korea. In the Mediterranean P. semisulcatus is becoming important to the fisheries in Turkey, Israel and Egypt.
