Environmental Changes, Habitat Modifications and Feeding Ecology of Freshwater Fish

Fish feed is one of the most expensive elements needed for fish culture. For the best and the most efficient use of feed, it is critical when raising fish to determine what affects the fishes’ ability to feed in a specific rearing scenario. Many factors can affect the fishes’ feeding activity. The importance of understanding the feeding behavior in fish and their effects is demonstrated in numerous publications ( Cowey et al. , 1985 ; Thorpe and Huntingford, 1992 ; Houlihan et al. , 2001 ). Factors affecting feed consumption and growth in fish are also frequently found in the existing literature. The feed may be exactly formulated to meet all the nutritional requirements of the fish but it needs to be presented to the fish considering all the factors to ensure optimal consumption.
