Farms that (30)are located in deep, well-flushed waters can usually avoid creating risks for the water quality of benthic(深海底的)communities.
If waters are not well flushed and sufficiently deep, feeding the caged fish can lead to excessive(31)accumulation of nutrients and wastes, which endangers the balance necessary to sustain wild populations.
About half of all fish(32)consumed globally are produced in farms, and the amount is likely to increase to meet the world’s demands for protein. Overfishing of many traditional fishing grounds has depleted native supplies just as expanding populations and greater(33)affluence create a demand for more fish in the markets.
The rising world population is becoming more(34)reliant on aquaculture for food production. In the US, domestic aquaculture can aid in decreasing US dependence on imported products, provide jobs and food security, and meet the rising demand for seafood. NOAA is working to(35)ensure that industry growth occurs within a framework of environmental responsibility and ocean stewardship.
