In some districts rucahnya fish supply is already inadequate, for example in Riau, grouper fed with feed in the form of tuna / tuna raw small size. They sacrificed a small tuna because they are less expensive than live grouper. They forget that tuna / tuna was the embryo of small boulders / tuna size. When farming activities such as running and continues to be intensive, so stocking tuna / tuna in our waters will decline drastically in a short time.

Strategy was done on yellow tail fish (Yellowtail) or red snapper (red seabream) in Japan, which was initially not able to take advantage of artificial feed the habit, to be replicated for grouper.
3. Leer fishes herbivorous / omnivorous
Freshwater fish are generally able mensintesa omega-3 EPA and DHA from C18 fatty acids. So they do not need exchanged so the oil / fish meal in the feed. Therefore, the development of fish farming are herbivorous or omnivorous as a source of animal protein, can be a substitute alternative types of carnivorous fish farming.
Some Japanese researchers have started thinking to develop herbivorous fish. But they did not have much choice of fish. Tilapia has shown growth and good quality meat but only fed in the form of plankton, can not live freely in the realm of Japanese with a very temperature varies by season. In addition, Japanese people are not very happy eating freshwater fish.
On the other hand, some types of freshwater fish that has long we developed, such as tilapia, mujair, Gurame, carp and catfish, can be further improved its production, either through improved farming systems or biotechnology applications. There are several types of freshwater fish, such as tilapia and mujair, can live in a wide range of salinity. The fish like this we can develop for the future.

This technique can be used to enhance the adaptation of freshwater fish in salinity brackish water or sea water even more constricted untukmengantisipasi freshwater cultured land.
