During spawning, fish behavior consists of a set of instinctive actions, that are invoked in a certain order and under the influence of specific stimuli.

For example, consider the behavior of such fish as grayling. For male grayling before spawning it is very important to occupy the spawning area with appropriate bottom and cover. Such a marriage he protects from other males, who also dressed in a marriage outfit and already his appearance allures females.

Female, reacting to the actions of the male, should be willing to spawning, and if it does not, then the male just chased her.

What happens next is the following – if the female was hunched over and dropped his dorsal fin the male dorsal fin down to the back of the female and tail around her, then they huddle to the bottom, and the female lays eggs and the male fertilizes her milk. In the case for grayling the importance of vision – he sees the spawning ground and the willingness of females to the inflorescence emerge caviar. Irritants there are the quality of bottom and position of the dorsal fin of the female.

The reflexes and instincts of fish can be used in their artificial breeding. For example, juvenile salmon can be taught to independently use automatic feeders.
