ABSTRACT
In freshwater sector, cage culture allows farmers to use existing water resources that may or may not be used for other purposes. The cage culture was initiated in Norway during 70s and developed into an organized industry, particularly for salmon farming. Cage culture in open seas requires a fish variety with the basic characters like, suitability for marketing, commercial importance, consumer accepted fish, easy to culture, adaptability to the cage environment, acceptance to artificial diets, faster growth rate and resistant to common diseases. It is considered as one of the most promising candidates for warm water marine fish aquaculture in the world. Statistics of FAO (2009) show that the Since late 1990, cobia aquaculture production has been steadily expanding in Asia, primarily in Taiwan, Vietnam and China, but also in other Southeast and Indo-Pacific Asian countries including the Philippines, Indonesia, Iran and Reunion Island.
