In a world where the global population is expected to grow by another 2 billion to reach 9.6 billion people by 2050 and where more than 800 million continue to suffer from chronic hunger we must meet the huge challenge of feeding our planet while safeguarding its natural resources for future generations. (SOFIA, 2014). Global fish production has grown steadily in the last five decades, with food fish supply increasing at an average annual rate of 3.2 percent, outpacing world population growth at 1.6 percent. Cage culture systems employed by farmers are currently as diverse as the number of species currently being raised, varying from traditional family-owned and operated cage farming operations (typical of most Asian countries) to modern commercial large-scale salmon and trout cage farming operations in northern Europe and the America. Commercial cage culture has beenmainly restricted to the culture of higher-value (in marketing terms) compound-feed-fed finfish species, including salmon (Atlantic salmon, cohosalmon and Chinook salmon), most major marineand freshwater carnivorous fish species (including Japanese amberjack, red seabream, yellow croaker, European seabass, gilthead seabream, cobia, Rainbow trout, Mandarin fish, snakehead)and an ever increasing proportion of omnivorous freshwater fish species (including Chinese carps, tilapia, Colossoma, and catfish). However in southeast Asian countries, marine species being cultured are groupers and snappers.
