Aquaculture looks to be the future of fishing:- Aquaculture - Wikipedia, the free encyclopedia
Interesting statistic: "This farming provides half of the total fish and shellfish we eat." *
Also another interesting page on Wikipedia Fish farming - Wikipedia, the free encyclopedia
Fish cages are placed in lakes, bayous, ponds, rivers or oceans to contain and protect fish until they can be harvested. They can be constructed of a wide variety of components. Fish are stocked in cages, artificially fed, and harvested when they reach market size. A few advantages of fish farming with cages are that many types of waters can be used (rivers, lakes, filled quarries, etc.), many types of fish can be raised, and fish farming can co-exist with sport fishing and other water uses. Cage farming of fishes in open seas is also gaining popularity. Concerns of disease, poaching, poor water quality, etc., lead some to believe that in general, pond systems are easier to manage and simpler to start. Also, past occurrences of cage-failures leading to escapes, have raised concern regarding the culture of non-native fish species in open-water cages. Even though the cage-industry has made numerous technological advances in cage construction in recent years, the concern for escapes remains valid.

Aquaculture is also listen on the EU website at Fisheries and Maritime Affairs (Vital to the economy...) Looks like they want an increase in it...
Aquaculture can offset declining wild fish stocks. Already, 19% of the tonnage caught by the EU fishing industry comes from fish farms. Molluscs, mussels, rainbow trout and salmon are generally the most important aquaculture products, but carp and sea bream are important in some countries.
The EU industry has been growing less rapidly than the rest of the world's. The European Commission is considering additional steps to develop this industry's potential. The key challenges include a lack of space and of water of good quality, and high standards of protection for public health and the environment. European aquaculture is at the forefront of sustainable development in the world, both in terms of social and environmental impacts, but this makes it more difficult to compete with producers in other countries, especially in Asia and in South America.
