Progress in fish‐cultural practices has been much slower than it should have been. The trend in trout culture has been to increase the size of fish reared for stocking. Legal‐sized fish are now planted in many states. Rearing trout to larger size resulted in many problems such as the need for better and cheaper diets, adequate facilities for holding fish, and the prevention and control of disease. The possibilities in selective breeding are discussed. Progress in bass culture has been more rapid than that in trout. The extensive and intensive methods of rearing bass are described and discussed. The need of experimental work for improvement of fish‐cultural practice is urgent.
