Abstract

The Green tiger shrimp, Penaeus semisulcatus De Haan, 1844, is an important commercial penaeid shrimp in capture fisheries and culture practices due to its large size and fast growth rate. It is known as ‘Mandapam flower or Flower shrimp’ in the international market. P. semisulcatus contributes over three-fourths of the shrimp landings in Palk Bay and the Gulf of Mannar. Palk Bay (9° 55’ to 10° 45’ N and 78° 58’ to 79° 55’ E), situated in Tamil Nadu on the southeast coast of India, has a coastline of approximately 296 km spanning from Point Calimere in the north to Dhanushkodi in the south. The coastline comprises five revenue districts: Nagapattinam (58 km), Thiruvarur (19 km), Thanjavur (29 km), Pudukkottai (49 km), and Ramanathapuram (141 km). Palk Bay’s muddy bottom and seagrass ecosystem supports shrimp fishery, particularly P. semisulcatus. It is extensively distributed in the Indo-West Pacific region, the Red Sea, eastern and southeastern Africa, Japan, Korea, the Malay Archipelago, and northern Australia. In India, it is distributed on both the east and west coasts, forming a fishery in the Palk Bay and Gulf of Mannar with its abundance gradually reducing south to north on the east coast. On the west coast, it forms a fishery only along the Gujarat coast, from October to November.
