How do fish fertilize each other in a fish farm?
As presently phrased, your question is rather meaningless. The process is sexual. That said, crafty fish farm owners have been known to help out. They can sexually stimulate the males so as to encourage an ejaculation of sperm. This can be collected and then strategically introduced to the eggs laid by the females. That sort of kinky intervention can result in more small fry then if the process were left entirely up to the fish.
