Cultivable marine
fishes
The Convention on Biological Diversity 1993 identifies mariculture as a
rapidly developing industry
The mariculture
potential of India is vast as there is great scope for developing farming
of sea bass, groupers, mullets,
milkfish, apart from prawns, oyesters seaweeds etc
The open sea cage culture has been expanding in recent years on a global
basis
(Read the notes of Mullets, milk fish, Seabass here)
Groupers
Groupers are
generally sold alive at a size range of 0.5–1.2 kg per fish, with the average
weight for table-size fish being 850 g. These can be cultured in cages
