Aquaculture, or the farming of fish under controlled conditions, was the only way to meet the future global demand for fish, the UN Food and Agriculture Organisation (FAO) said late last year.
Rising human populations meant that by 2030 another 37 million tons of fish would be needed to maintain consumption levels.
According to the FAO, about 45 percent of the 48 millions tons of fish consumed each year is raised on farms. The addition of 2 billion people globally by 2030 means farming will have to produce nearly double that to keep up with demand.
Jacques Diouf, the FAO director-general, told a meeting in Rome that while the development of aquaculture should be a priority, it must be promoted in a responsible fashion.
"A rapid development of aquaculture … requires better planning and better management of the sector in order to mitigate the adverse consequences on the environment," Diouf said.
