Problems solved by technology

[0002] Antibiotics can prevent and control the prevalence of bacterial diseases in aquatic animals to a certain extent, but the indiscriminate abuse of antibiotics can not only cause bacteria to develop multi-drug resistance, but also cause the immune function of aquatic animals to decline, microbial flora imbalance and drug residues in the body And other issues
There is no report on the application of PHB in the breeding of aquatic economic animals

Embodiment Construction

[0017] Below in conjunction with the examples, the present invention is further described, the following examples are illustrative, not limiting, and the protection scope of the present invention cannot be limited by the following examples.

[0018] Artemia enhancement is to use its non-selective filter-feeding characteristics to wrap a certain size of granular substances in the digestive tract of Artemia, and the aquatic seedlings will ingest the wrapped objects indirectly by preying on Artemia, which not only achieves the purpose of transporting nutrients The purpose of these materials can avoid the waste and water pollution caused by directly adding these substances into water.

[0019] A method for strengthening artemia larvae with poly-β-hydroxybutyrate, and the best method for strengthening artemia was proved by the following experiments.

[0020] In experiment 1, the concentration of PHB was set to 0, 50, 100, 200, 400 and 800 mg / L, respectively, to explore the optimal ...

Abstract

The invention relates to a strengthening method of poly-belt-hydroxy butyrate to larva of artemia. The strengthening method is characterized in that: when the larva of the artemia is strengthened by the poly-belt-hydroxy butyrate, the concentration of the poly-belt-hydroxy butyrate is 100mg / L, the strengthening time is 24h, and the grain size of the poly-belt-hydroxy butyrate is 10-50 mu m. The poly-belt-hydroxy butyrate (PHB) is the biological control agent which is wide in application prospect and can replace the antibiotic, and the research of the application of the poly-belt-hydroxy butyrate in the aquiculture is under the infancy stage at home currently and firstly. The strengthening method shows the influence of the PHB with different concentrations and the different strengthening and cultivating times to the survival rate and the growth of the larva, and is best in the strengthening effect to the larva of the artemia by 100mg / L PHB within 24 hours, so that the strengthening method has a good guide meaning for researching the application of the PHB in aquatically seedling.

Description

technical field [0001] The invention belongs to the field of aquaculture, in particular to a method for strengthening artemia larvae with poly-β-hydroxybutyrate. Background technique [0002] Antibiotics can prevent and control the prevalence of bacterial diseases in aquatic animals to a certain extent, but the indiscriminate abuse of antibiotics can not only cause bacteria to develop multi-drug resistance, but also cause the immune function of aquatic animals to decline, microbial flora imbalance and drug residues in the body And other issues. Short-chain fatty acids have a wide range of physiological functions such as antibacterial, reducing animal intestinal pH, and promoting the absorption and utilization of nutrients. They are bioactive substances and feed additives with promising application prospects. Poly-β-hydroxybutyrate (Poly-β-hydroxybutyrate, PHB) is a polymer of short-chain fatty acid β-hydroxybutyric acid, which is fat-soluble particles with a certain particl...
