Aquaculture production of seafood will continue to grow through 2025

Washington, Jan 2 (ANI): An assessment has revealed that aquaculture production of seafood will probably remain the most rapidly increasing food production system worldwide through 2025.

The assessment, by James S. Diana of the University of Michigan at Ann Arbor, notes that despite well-publicized concerns about some harmful effects of aquaculture, the technique may, when practiced well, be no more damaging to biodiversity than other food production systems.

Moreover, it may be the only way to supply growing demand for seafood as the human population increases.

According to Diana, the total production from capture fisheries has remained approximately constant for the past 20 years and may decline.

Aquaculture, in contrast, has increased by 8.8 percent per year since 1985 and now accounts for about one-third of all aquatic harvest by weight.

Finfish, mollusks, and crustaceans dominate aquaculture production. Seafood exports generate more money for developing countries than meat, coffee, tea, bananas, and rice combined.

When carefully implemented, aquaculture can reduce pressure on overexploited wild stocks, enhance depleted stocks, and boost natural production of fishes as well as species diversity, according to Diana.

Some harmful effects of aquaculture have diminished as management techniques have improved, and aquaculture has the potential to provide much-needed employment in developing countries.

Diana points to the need for thorough life-cycle analyses to compare aquaculture with other food production systems.

Such analyses are, however, only now being undertaken, and more comprehensive information is needed to guide the growth of this technique in sustainable ways. (ANI)
