Title
Non-starch polysaccharides and their role in fish nutrition : a review
Author
Abstract
The success and sustainability of aquaculture depends on minimising the operational cost of feed that in general comprises 5060% of the total cost in intensive farming. The major feed ingredient, fish meal, is expensive and there is increasing competition with other livestock industries for the available static supply of fish meal. Hence, the incorporation of plant-derived materials in fish feeds is receiving increasing attention. One of the main constraints in the utilisation of plant ingredients in aquaculture is the presence of indigestible carbohydrates, which consist primarily of non-starch polysaccharides (NSPs). These form a part of the cell wall structure of cereals and legumes. The presence of NSPs in the diet interferes with feed utilisation and adversely affects performance of the animal. Supplementation of NSP-degrading enzymes in feed mitigates the adverse effects of NSPs. The effects of NSPs in pigs and poultry have been widely studied; however little information exists for fish. This review synthesizes the available information on fish and highlights the knowledge gaps. It is hoped that this review will provide a momentum to the research on the roles of NSPs in fish nutrition and physiology and on the efficient use of NSP-degrading enzymes. Research highlights ► Replacement of fish meal with plant based ingredient, Non-starch polysaccharides (NSP). ► NSP acts an anti-nutritional component, adversely affects performance of the fish. ► Compared to livestock, little information on effect of NSPs exists in fish. ► This review offers the existing information on fish and highlights the knowledge gaps. ► Incorporation of NSP-degrading enzymes in feed mitigates the adverse effects of NSPs.
