Southern Rough Shrimp Characteristics

The Southern Rough shrimp is relatively a small sized prawn. The exoskeleton is “densely pubescent” (covered in thick down).

It can be distinguished from similar species by the form of the petasma and thelycum, and also by the coloration of the uropods. Their uropods are red or reddish brown, with conspcuous white margins.

Rostrum of the Southern Rough shrimp is straight or slightly curved upwards, and bears 7-11 teeth on the dorsal side. The last 4 segments of the pleon have a median crest, while the second segment has a tubercle on the mid-line.

On an average, the females can reach a total length of 105 mm. While the males are much smaller, reaching about 81 mm.

The Southern Rough shrimp is a commercially important species in China, Japan, Korea and Taiwan. It is also fished on smaller scales in the Red Sea, Gulf of Aden, Arabian Sea and Madagascar.

It is also abundant around the coasts of Australia, but is too small to be commercially viable there. But is very important in Chinese fishery.

It is less important in Indian fishes, because it is not found in larger numbers for contributing to a fishery.

It is used mainly for food, but also used as bait shrimp. However, review full breed profile of the Southern Rough shrimp in the table below.
