Introduction of some methods of nursery rearing of (lates calcarifer) in cages and ponds

The need for more food for humans and especially marine proteins, has led to a growing trend in the production of marine fish cage culture in the country. The issue of rearing various species of marine fish for aquaculture in cages in the south of the country has risen. But now the farmers have chosen as the first option according to the characteristics of the growth and tolerance of suitable environmental conditions, Asian sea bass species. Due to the lack of native species in the country and the specific strategy of this species, the expansion of this industry requires artificial propagation and the supply of larvae fish for rearing. Now the private sector needs a suitable fish through imports of fish larvae, the nursery of larvae in special breeding centers, and the sale and distribution of juvenile fish among farmers. Hence farmers are spending a lot of money to buy juvenile fish at the suitable size and transport to cages. In this article, we will try to provide a brief overview of the various methods of nursery rearing stages of Asian sea bass in cages, tanks and pools in some countries, so breeders can design and implement programs for rearing larvae to prepare to stock in the cage. The development of this industry in the country needs to reduce production costs to achieve better economic efficiency for sustainable production.
