Nutritionists are advising people to eat more fish, since the omega-3 fatty acids in fish help combat many diseases  If everyone took this advice, however, there would not be enough fish in oceans, rivers, and lakes to supply the demand  the oceans are already being overfished
The obvious method to ease the pressure on wild fish populations is for people to increase their consumption of farmed fish
There are large expanses of ocean waters that do not contain enough nutrients to support substantial fish populations.
