Sea cucumber culturing feed additive and preparing and using methods thereof

Abstract

The invention discloses a sea cucumber culturing feed additive and a preparing and using method thereof. The feed additive is prepared from medical stone and Chinese herbal medicaments, wherein the mass mixing ratio of the medical stone to the Chinese herbal medicaments is 50-70:50-30; and the Chinese herbal medicaments comprise 30 to 50 mass percent of raidx astragali, 15 to 25 mass percent of Chinese angelica, 5 to 15 mass percent of common andrographis herb, 5 to 15 mass percent of honeysuckle flower, 5 to 15 mass percent of indigowoad leaf and 5 to 15 mass percent of fried scorch-fried crataegus. The preparation method comprises: grinding the components respectively; sieving the ground components with a 60 to 100 mesh sieve; and feeding the ground components in ratio into a feed mixer to stir the components uniformly, wherein the required coefficient of variation (CV) of mixing precision is less than 10 percent. The ratio of the sea cucumber culturing feed additive to the feed is 1:9, the feed additive is added into the feed, and the mixture is mixed uniformly and used in a larva pool. The sea cucumber culturing feed additive has the advantages of avoiding secondary pollution, reducing water exchange, effectively promoting the growth of sea cucumbers, improving the body immunity and disease resistance of the sea cucumbers, reducing the use of antibiotics and chemical medicaments, along with widely available raw materials, safety, no toxicity and convenient use.

Description

technical field [0001] The invention relates to a feed additive for raising seafood molluscs, and at the same time relates to a traditional Chinese medicine preparation which can be beneficial to disease prevention, treatment and growth of molluscs. Background technique [0002] Sea cucumber is the most important aquaculture species in northern my country, its market demand and brand effect are still increasing, and the scale of sea cucumber seedlings is also increasing. In high-density seedling ponds, a large amount of bait and feces are deposited, causing a large number of bacteria, viruses and parasites to multiply. At the same time, high-protein organic matter is decomposed into highly toxic hydrogen sulfide, ammonia nitrogen, nitrite and other harmful substances under the action of bacteria. Seriously poisonous to pond bottom seedlings. Although many farms often change water and pour ponds, most of the fresh seawater has been polluted by discharged waste water, and the...

Problems solved by technology

In high-density seedling ponds, a large amount of bait and feces are deposited, causing a large number of bacteria, viruses and parasites to multiply. At the same time, high-protein organic matter is decomposed into highly toxic hydrogen sulfide, ammonia nitrogen, nitrite and other harmful substances under the action of bacteria. Seriously poisonous to pond bottom seedlings

Although many farms often change water and pour ponds, most of the fresh seawater has been polluted by discharged waste water, and the water quality improvement in nursery ponds is often not obvious, causing sea cucumbers to live in polluted and high-level toxic substances for a long time. Over time, toxicity Substances attack the body of sea cucumbers, reducing their resistance, which in turn causes the harm of bacteria, viruses, parasites and other microorganisms. When the weather suddenly cools or changes in warming conditions, it will lead to the outbreak of extremely serious rotting skin syndrome in sea cucumbers. disease

[0003] In addition, due to the high density and narrow range of activities of artificially cultured sea cucumbers, the intake and absorption of vitamins and trace elements are limited, especially the substances that are most conducive to the growth of sea cucumbers in natural sea areas. Sea cucumbers cannot be absorbed into the body in time, which will cause sea cucumbers. The imbalance, coupled with the low temperature in winter, sea cucumbers stop feeding, and the weakened body creates conditions for bacteria and viruses to invade

[0004] In order to avoid the huge economic losses caused by diseases, a large amount of antibiotics and chemical drugs are used for disease prevention in breeding, which seriously damages the micro-ecological environment in the water body and the intestinal tract of sea cucumbers, and leads to the increase of drug resistance of pathogenic bacteria, which eventually leads to the development of animal diseases. The dependence on antibiotics and chemical drugs and the increasing dosage of drugs have seriously affected the quality of sea cucumber products and the health of consumers

Some products have been developed in the research of antibiotic substitutes and water purification, and some have also become commercial products, such as microecological preparations, Chinese herbal medicines, etc., but most of them are only one-sided for organisms or one-sided for water bodies, and the Chinese herbal medicines used in related research need to be boiled. It is not suitable for large-scale application, especially without formulating prevention and control strategies for the disease characteristics and environmental incentives of sea japonicus seedlings in spring and summer.
