Discussion summary

A question was posed regarding the possible advantages of aquaculture in the sea rather than in inland ponds. It was pointed out that control of seed fish, breed, and feed is more difficult in the sea, although under controlled circumstances, molluscs do well in certain bays. There are great possibilities for future aquaculture in the sea, but this will depend on the genetic modification of existing marine species.
