Fish feed is the major expenditure for fish farmers. Good fish feed management can reduce overall culture cost, improve fish farm environment and ensure healthy growth of fish stock. Fish feed management includes choosing the right feed, using the correct feeding method, calculating the feeding cost and ensuring the cost effectiveness of fish farm.
It is noteworthy that nutritional requirements of fish vary with different species, sizes, growth stages and feeding habits.
For example, carnivorous fish require a higher intake of protein and fat than the omnivorous and herbivorous species, while marine fish require more protein
and fat than freshwater fish do. For this reason, fish feed should be specifically chosen to suit different species.
