Ontogenetic Changes in Vulnerability of the Prawn Fenneropenaeus indicus to UV-B Radiation Help Explain Ontogenetic Habitat Shifts
The Indian Ocean white prawn (Fenneropenaeus indicus H. Milne Edwards, 1837) is distributed across the Indian Ocean, from southern Africa to northern Australia and the Red Sea, and is also present in all of South-East Asia, where F. indicus is a major commercial fishery species. F. indicus has been domesticated for aquaculture and is extensively cultured in farms throughout South-East Asia, India, the Middle East, Saudi Arabia, and eastern Africa (Ling et al. 1999).
F. indicus is a non-burrowing prawn species preferring a sandy or muddy bottom, and although active at both day and night, it has been shown to display clear daily rhythms in activity, being less active at night (Natarajan 1989). F. indicus has a complex ontogenetic developmental cycle involving 12 stages distributed in three planktonic larval forms (6 nauplii stages, N-1 to N-6; 3 zoea stages, Z-1 to Z-3; and 3 mysis stages, M-1 to M-3). F. indicusdevelops from hatching to the post larva (PL) stage over 10...
