Replacement of fish oil and meal with vegetable compounds in aquatics diet

Due to the global problems of supplying oil and fish meal, plant oils are the only suitable alternative to the aquatics diet. In this scrutiny, the levels application of vegetables compounds with flour and fish oil in the diet of aquatic animals were compared by researchers in Iran during years 1998 to 2019. Soybean and its processed and modified products (10 to 50% level), canola meal (20 to 100%), flaxseed meal (10 and 15%), rice protein concentrate(25%),cotton seed meal(20 and 35%), irradiated Chickpea (40%), Azolla meal (15 and 21%) ,corn gluten meal (60%), Sargassum meal(15%),barely protein concentrate (25%), and wheat Gluten (no effect) as alternatives to fish meal and rapeseed oil (60%), canola (50%), Flax (75%), grape seed (50%), soybean (10%), canola and soybean combination (50 and 100%), mixture of cotton seed, soybean and grape seed (100%), combination of canola, flax, sunflower and safflower (80%), mixture of canola, flax and safflower (100%) were Fish oil substitutes in aquatics diet. The results showed that in the aquatics diet, vegetable oils can be replaced at a higher level than vegetable proteins. Due to the development of cultivated surface area of oilseeds in Iran, this potential could be used to reduce the dependence of fish oil in aquatics diet.
