Abstract

The invention provides a feeding method for fugu rubripes at different growth stages. The feeding method comprises the steps that in the fry stage, rotifers are splashed and fed, the feeding density of the rotifers is 10-15/ml, and the rotifers are fed once a day; in the juvenile fish stage, artemia is splashed and fed, the feeding density of the artemia is 5-10 pieces/ml, and the artemia is fed twice a day; after the artemia is fed for one week, pellet feed is added for domestication, and small-particle floating feed is mainly used as the feed; in the juvenile fish stage, pellet feed is fed, the total feeding amount is 1%-3% of the total mass of juvenile fish, and feeding is carried out four times a day; in the adult fish stage, pellet feed is used for feeding, and the total feeding amount is 2%-3% of the total mass of adult fish; and in the parent fish stage, pellet feed is used as main food, jade squid, anchovy, squid, nereis and the like are used for auxiliary feeding, and the total feeding amount is 2%-4% of the total mass of parent fish. The bait is reasonably utilized, the breeding cost is reduced, and the bait conversion rate is high.

Description

technical field [0001] The invention relates to the technical field of redfin puffer culture, in particular to a method for feeding puffer in different stages. Background technique [0002] Takifugurubripes belongs to Chordata, Osteichthyes, Telraodontiformes, Tetraodontidae, Fugu. Because of its rich nutrition, delicious meat quality and high economic value from breeding, it has become one of the largest species with the highest economic value in the culture of pufferfish in seawater in my country. In my country's Hebei, Liaoning, Shandong and other places, there are large-scale pufferfish breeding industries, which have obvious characteristics of industrial agglomeration. my country's research on pufferfish began in the early 1980s, and in the 1990s important progress was made in raising seedlings and breeding. In 2000, the cage culture of pufferfish was successfully realized. [0003] At present, the feeding of red-finned puffer is mainly based on pellet feed, jade teng...
