Feed additive for sea crabs and preparation method of feed additive

Abstract

The invention discloses a feed additive for sea crabs and a preparation method of the feed additive. The feed additive is prepared from the component in parts by weight as follows: 105-120 parts of anoleic acid solution of saline-alkali-resistant modified and irradiation splitting modified bamboo leaf extract. The feed additive is mainly applied to high-quality sea crabs, the specially extractedbamboo leaf extract is subjected to targeted modification treatment and is reasonably combined and properly applied, the advanced feed additive which is resistant to saline-alkali, capable of improving meat quality, improving cold nature of sea crab meat and increasing nutritive value of the sea crabs and adaptive to coastal reclamation free-ranging is obtained, the blank of the industry is filledup, and the feed additive has great significance for environment-friendly ecological sea crab breeding.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a feed additive for sea crabs and a manufacturing method thereof. Background technique [0002] Sea crabs in this paper mainly refer to swimming crabs, whose natural growth environment needs to inhabit shallow coastal seas, and often dive into the sandy bottom and move and migrate within a certain range. Swimming crabs are omnivorous animals, they like to eat shellfish, fresh miscellaneous fish, small miscellaneous shrimp, etc., and also eat algae buds, marine animal carcasses and rotting aquatic plants. And different growth stages, feeding habits are different, in the young crab stage tends to be omnivorous, and the larger the individual, the more carnivorous. There are two main methods for existing sea crab farming, one is to divert seawater into the inland for feeding, and the other is to raise sea crabs in a free-range manner. For inland feeding, the cost of breeding ponds is hig...

Problems solved by technology

For inland feeding, the cost of breeding ponds is high and maintenance is difficult. At the same time, the requirements for crab species are high (it must be a species with a small range of activities), and due to lack of exercise, the taste of this crab is actually inferior to that of free-range sea crabs. of

However, the free-range sea crabs in the prior art, because they are cultured in the sea, the seawater has strong fluidity, so they generally cannot be spread over the entire area when feeding, and can only be scattered at the shore to wait for the feed to move naturally, and fluid cannot be used. Feeds that are easy to absorb, such as fish or powder, because although these feeds are easy to absorb, most of them will be washed away by sea currents

Simultaneously, the meat quality of the sea crab cultured in the prior art presents strong coldness, and people with physical weakness are prone to cause diarrhea after eating, which has caused certain restrictions on the marketing of sea crabs
