| Popis: |
Fish in the wild seldom show signs of nutritional disease. This is because natural aquatic foods are not deficient in essential nutrients; the diet may be deficient in quantity but not quality. It is when fish are confined to an artificial environment and intensively fed for rapid weight gain that nutrition-related diseases can occur. Nutrition-related diseases can be described as a) physiological or morphological anomalies resulting from dietary nutrient deficiency; b) materials in the diet which are toxic to the fish; and c) reduction in resistance to infection caused by diet quality or feeding practice. Anomalies resulting directly from nutrient deficiencies have been described in and diet related toxins are discussed in . Effects of nutrition on resistance of fish to infectious diseases are discussed in this chapter. |
