1. A process for pre-conditioning pompano in preparation for induced spawning which comprises isolating a brood stock of sexually immature fish from the natural environment by placing the stock into a water media suitable for sustaining life in a healthy condition, limiting the light exposure to a period of between 8 and 10 continuous hours per 24 hour period during which the intensity of light is between 500 and 1,000 foot candles and the water temperature is maintained between 90*C. and 23*C. for suppressing the sexual development of the brood stock until spawning is desired, and thereafter readjusting the temperature and degree of light exposure and intensity by increasing the period of light duration to about 16 continuous hours per 24 hour period using a light source having an intensity of between 500 and 1,000 foot candles and the water temperature is maintained at between 25*C. and 29*C. for rapidly attaining the sexual maturity of the brood stock.
