Problem

Obstacles to aquaculture

Other Names:
Lack of hydroponics
Limited fish farming
Nature:
Fish have been raised for centuries in flooded fields and ponds. More recently these technologies have become a major focus of development efforts concerned with food production. Both the raising of fish and of plants in water without soil are unusual agricultural efforts, however. Only the wealthier and more innovative farmers are interested. Consequently, schemes that on paper and in a government-sponsored agricultural station sound quite impressive are not tried.
Claim:
There is little scientific support of aquaculture. The usable surface area of the oceans is relatively small; the open sea is unsuitable. Coastal areas and shallow seas are highly prized by commercial and sport fishermen, pleasure boaters, swimmers, oil and other mineral explorers, housing developers and those who dump waste. The increasing amounts of pollution: sewage, industrial wastes, fertilizers, pesticides, silt, heated water, trash, oil, and radioactive substances are making some whole seas unsuitable for aquaculture. Unclear ownership rights of seas, even coasts increases the risk of potential sea farmers. Conservation laws sometimes prevent its development by forbidding the capture of young animals or of mature females. The number of marine animals which can be cultivated is small.
