[2] In the Persian Gulf, P. semisculatus spawning was at its height during December and in March, but a secondary peak occurred in autumn; 90% of the female prawns reached sexual maturity after attaining a carapace length of 54 mm.

[3] Penaeus semisulcatus is of minor to moderate importance in Madagascar, along the eastern coast of Africa and in the Red Sea.

Along the southwestern Asian coasts from the Gulf of Aden to Pakistan, this species is of major importance to the offshore fishery.

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.

[3] In 2017, an outbreak of white spot disease occurred in Southeast Asia, leading Australia to ban prawn imports.
