不要翻的太机械了哈 急---------
The good news is that the industry is improving.More farmable but less familiar species like the barramundi — which yields more protein than it takes in as feed — may have to supplement popular fish like cod that haven't taken as well to aquaculture.We may even need to genetically engineer popular species to make them grow faster and bigger.And perhaps most of all,we need to accept that on a planet with a population of nearly 7 billion and climbing,we may no longer be able to indulge our taste for the last wild food.We've farmed the land.Now we have little choice but to farm the sea as well.
Aquaculture and Its Discontents To the average shopper,farmed fish is barely distinguishable from its wild cousin — except,often,in price.Without the growth in aquaculture,many of our favorite kinds of seafood would likely be much more expensive than they are now.And chances are,you get what you paid for:farmed seafood can be inferior to wild fish in taste and may not always have the same nutritional value.Salmon raised in an aquaculture environment,for instance,often have lower levels of cardiovascular-friendly omega-3s than wild fish,and farmed fillets would actually be gray without a pink chemical dye.And if you're eating farmed seafood,you're almost certainly getting it from overseas:U.S.aquaculture accounts for just 5% of Americans' seafood consumption.The Monterey Bay Aquarium's Seafood Watch program mostly discourages consumers from choosing farmed fish,both for health reasons and because of worries over the environmental impact of aquaculture."There's a real difference in the regulation you might see in other countries compared with the U.S.," says Peter Bridson,Monterey's aquaculture-research manager.At the same time,it's important to look at the big picture.For health reasons,most of us should be eating more fish.For its new dietary guidelines,the U.S.government just upped the recommended consumption of seafood to 8 oz.or more a week — which is more than twice what the average American eats — and 12 oz.for pregnant women.In a report this month,the U.N.said global food production would need to increase by as much as 100% by 2050 to meet growing demand — and seafood,as a vital protein source,will have to be part of that.Farming is unavoidable."There may be a price split between expensive wild fish and cheaper farmed fish," says Don Perkins,head of the Gulf of Maine Research Institute."But seafood consumption will spread because we need it for health reasons."
