“…In rainbow trout, Mn and Zn deficiencies depressed natural killer activity of leucocytes and activity could be restored to normal levels by feeding diets with sufficient levels of these trace elements (Inoue, Satoh, Maita, Kiron & Okamoto 1998). In sockeye salmon, Oncorhynchus nerka (Walbaum), diet supplementation with both Mn and Zn did not improve fish resistance against bacterial kidney disease (Bell, Higgs & Traxler 1984) while survival was related to dietary vitamin C level (supplied as ascorbate‐2‐sulphate) only when diets contained low levels of Zn and Mn.…”

Under intensive culture conditions, fish are subject to increased stress owing to environmental (water quality and hypoxia) and health conditions (parasites and infectious diseases). All these factors have negative impacts on fish well-being and overall performance, with consequent economic losses. Though good management practices contribute to reduce stressor effects, stress susceptibility is always high under crowded conditions. Adequate nutrition is essential to avoid deficiency signs, maintain adequate animal performance and sustain normal health. Further, it is becoming evident that diets overfortified with specific nutrients [amino acids, essential fatty acids (FAs), vitamins or minerals] at levels above requirement may improve health condition and disease resistance. Diet supplements are also being evaluated for their antioxidant potential, as fish are potentially at risk of peroxidative attack because of the large quantities of highly unsaturated FAs in both fish tissues and diets. Functional constituents other than essential nutrients (such as probiotics, prebiotics and immunostimulants) are also currently being considered in fish nutrition aiming to improve fish growth and/or feed efficiency, health status, stress tolerance and resistance to diseases. Such products are becoming more and more important for reducing antibiotic utilization in aquafarms, as these have environmental impacts, may accumulate in animal tissues and increase bacterial resistance. This study reviews knowledge of the effect of diet nutrients on health, welfare and improvement of disease resistance in fish.

Feeding experiments were conducted to determine the bioavailability of new types of manganese (Mn) supplement to rainbow trout fingerlings. Two levels of Mn (7 and 14 mg kg−1 diet) were supplemented to diets using either manganese sulphate (Mn‐S), glass‐embedded Mn (Mn‐Gl), or amino acid‐chelated Mn (Mn‐Am); more than one acid was used to chelate the metal. Rainbow trout weighing 1.30 g on average were fed the experimental diets for 12 weeks. Absorption of Mn from various compounds was evaluated using larger fish (105 g on average) fed the experimental diets. Growth was higher in the group supplemented with Mn‐Am at both levels. Whole‐body Mn content in fish fed the diet supplemented with Mn‐Am was significantly higher than the other sources. Bone Mn accumulation was significantly higher in treatments with 14 mg Mn kg−1 diet from all sources, except Mn‐Gl. At 7 mg kg−1, absorption from Mn‐Am was significantly higher than from Mn‐Gl and Mn‐S. Mn retention from both levels of Mn‐Am supplementation was significantly higher (P < 0.05) than the rest. The results indicated that amino acid‐chelated Mn provided more bioavailable nutrient than Mn‐S and Mn‐Gl. Further, availability of Mn from Mn‐Gl is equivalent to that of Mn‐S.

“…As macrophages, granulocytes are mobile and phagocytotic, but their bactericidal activity is not as high as that of macrophages (Secombes et al, 1996). In some fish species there is a particularly well-developed cell-mediated cytotoxic capacity, mediated through non-specific cytotoxic cells (Pettey & McKinney, 1988;Haynes & McKinney, 1991;Inoue et al, 1998). In bony fish, the NCC cells are considered to be analogous to natural killer (NK) cells in mammals, whereas macrophages appear to have that function in sharks.…”

“…In addition to being affected by endogenous factors, the diet of fish also affects their ability to combat disease. Components of the immune system appear to be particularly sensitive to deficiencies in trace metals (Scarpa et al, 1992;Inoue et al, 1998), lipid (Sheldon & Blazer, 1991) and vitamins (Hardie et al, 1990(Hardie et al, , 1991 in the diet.…”
