The invention discloses a
tropical fish feed, and a preparation method thereof. The
tropical fish feed comprises following ingredients, by weight, 27 to 32% of imported white
fish meal, 15 to 20% of corn
powder, 6 to 8% of
wheat germ powder, 10 to 12% of defatted soybean
powder, 8 to 10% of spiral seaweed powder, 10 to 12% of
shrimp meal, 3 to 5% of
yeast, 2 to 4% of composite
vitamin, 1 to 3% of mineral substance, and 1 to 2% of
carotenoid. The preparation method comprises following steps: (1) the ingredients are weighted according to the
mass ratio above, and are smashed in a
pulverizer so as to obtain
raw material mixed particles; (2)
purified water is added into the
raw material mixed particles, an obtained mixture is quickly stirred to be uniform, and
raw material mixture paste is obtained; (3) the raw material mixture paste is delivered into a sealed container for
fermentation; and (4) the fermented raw material mixture paste is delivered into a granulator for
processing so as to obtain the granular
tropical fish feed. The tropical fish feed is simple for preparation, is balanced in
nutrition, possesses color increasing effect, and is capable of increasing
immunity of tropical fish, and improving ornamental value of tropical fish; feed particles are uniform; impurities are few; and
water pollution is not caused.
