It depends on what form of aquaculture. species such as salmon and those that are carnivorous and actually require feed derived from wild fish. The amount of captured fish to raise farmed fish is massive (something like a ratio of 4:1) this then is a huge issue for the sustainability of wild fish stocks.

Beyond this many of the farms can be environmentally degrading affecting local fish with disease, escapment etc. additionally the seabed can become a wasteland. It should be noted that the extent of effects are limited by the location and size of farms.

If the GM fish were stronger, healthier, or grew faster, they might cannibalize the others. If the facility maintained a non-GM breeding stock, that should be end of it once the GM fish were removed. But it depends on what sort of new gene(s) were inserted.

extensive aquaculture is low production, low cost aquaculture. An example of this would be if you had a pond for raising Tilapia in Africa, and were only raising them to feed the community you were in.

I believe there are some fish farmers (marketers?) who have Tuna caught live and then keep and feed them in very large enclosures in the ocean prior to selling them in the Japanese live fish market. So it must be possible to keep some Pelagics this way but by their very nature Pelagic fish would not be a natural choice for fish farming.

The problem with Pelagic fish being suitable for aquaculture is what they eat. They require high levels of protein for growth. Also, they have very specific amino acid requirements that are usually only met by fish meal. The amount of fish meal (and its cost) needed to feed them until they are market size makes most pelagic fish not a good choice.

Aquaculture or fish farming started with the Chinese around 2,500 BC. It is thought that after a flood carp were trapped in lakes and that the Chinese started to feed and breed these carp as a source of food. This lead to the genetic mutation of goldfish.

The Romans also used lakes as fish farms, and this practise was also used in the Middle Ages to supply monasteries and manor houses with a regular supply of fresh fish.

So, in answer to your question, the first attempts at Aquaculture happened some 4,500 years ago, and has grown through experience to the massive business it is today.

Fry are fish just after they are hatched. They are very small and often actually look like dirt in the water. Fingerlings vary in size, but generally are older. Fry are stocked in the early spring as soon as the eggs hatch, fingerlings are stocked in the summer and fall after their chances of survival are greater. Walleye fingerlings are generally finger-sized if stocked in the early summer but may be 5-8 inches if stocked in the fall. Muskie fingerlings can be a foot long when stocked in the fall. Sometimes they wait until the fish actually switch from eating plankton to minnows before they stock them and then their chance of survival is much greater although it is a lot more costly and many hatcheries do not have the facitilites to keep them for an entire season.
