Answer:

Spawning is more difficult to induce in non-mature individuals than in mature individuals (Yamamoto, 1968; Nicholson, 1978; Malachowski, 1988), suggesting that internal physiological conditions have to be met before external stimuli effectively induce spawning. .

Most of the fishes exhibit seasonal cycle in the production of gametes. The expulsion of gametes from the body into the surrounding water is called "spawning" resulting in fertilisation. Fish spawns during a specified periods of the year which coincides with the several environmental factors that are available during the said period only.
