Why are many kinds of fish very easily produced in fish hatcheries?

This often relates to the behaviour of the fish or their requirements to breed (water quality, seasonal triggers).
For example; some fish (like livebearers) will readily breed under normal conditions. Others may require a large teritory, a certain ratio of males to females, specific water chemistry or food. Some species can be triggered to spawn in fish tanks by lowering the water level to simulate summer conditions whilst other may be prompted to spawn by adding some cooler water to the tank to simulate rainfall.
Also, the simplicity of reproduction is a large factor. Because some fish use a wasteful method where the female lays thousands of eggs and the male just releases everything into the water to try to fertilize something, people can use the method like that, but just in hatcheries so the fertilization can't float away.
