A sea cucumber bait rich in pha

Abstract

The invention relates to the technical field of aquaculture feed, in particular to a PHA-rich sea cucumber bait. Feeding sea cucumbers with a compound of sea mud and large seaweed powder as bait will cause a large amount of sludge to form at the bottom of the breeding pond, which will seriously affect the normal growth of sea cucumbers. In order to solve this problem, the present invention provides a sea cucumber bait rich in PHA , including the following ingredients: PHA, seaweed, scallops, dried sea rainbow, lactic acid bacteria dry powder, and marine red yeast powder; the sea cucumber bait structure prepared by the present invention uses PHA, a biodegradable material, to replace the sea mud ingredients in traditional sea cucumber baits It is compact and not easy to loosen. The sea cucumber bait that has not been swallowed by sea cucumbers is deposited on the bottom of the farm after being put into the farm. The PHA in the sea cucumber bait at the bottom of the farm can biodegrade and turn into CO 2 It solves the problem that the sea cucumber artificial breeding industry needs to regularly clean the bottom of the breeding pond, greatly saves manpower and material resources, and has a good application prospect.

Description

Technical field [0001] The present invention relates to the field of aquaculture feed, in particular, to a sea-rich bait rich in PHA. Background technique [0002] Sea cucumber is also called acupuncture, belonging to the ratclasses of the Ribinian Sea, which is distributed around the world, which is a historic marine molstone animal. The nutritional value of sea cucumber is high, and the study shows that the protein in the dry body wall is up to 70%, and the polysaccharide is about 4%, and the lipid is only 4%, and 90% of the lipids are phospholipids, and cholesterol only less than 1%. In the inorganic component, the stab containing the trace elements such as calcium, magnesium, iron and selenium, is known as the first year of "seafood eight", which enrichs the nutritional value makes the stabbed becomes a supplementary health food. [0003] It is based on the high nutritional value of sea cucumber. People have gradually increased the demand for sea cucumber, so it has also prom...

Problems solved by technology

[0004] At present, sea cucumber farmers or breeding enterprises mainly use the compound of sea mud and large seaweed powder as bait to feed sea cucumbers (Zhong Ming, Hu Chaoqun. Advances in research on sea cucumber breeding feed [J]. Feed Industry, 2016, 37(18) :58-64.), the content of sea mud in the bait is as high as 22-28%. For example, the Chinese invention patent CN103211088A discloses a kind of sea cucumber bait, its composition is: yeast 12%-18%, sea floating mud 22%-28% 12%-18% of eel algae powder, 2%-6% of lactic acid bacteria, 2%-6% of yeast, 2%-6% of photosynthetic bacteria, 2%-6% of bacillus, and the balance is purified Seawater, if the sea cucumber cannot be eaten at one time after the bait of this patent is put in, it will accumulate over time, which will cause a large amount of sludge to form at the bottom of the breeding pond

A large amount of sludge accumulated at the bottom of the breeding pond is very easy to breed a large number of Vibrio splendidus or pseudoalteromonas, which can easily cause the occurrence of sea cucumber rotting disease, and even cause a large number of sea cucumbers to die; in addition, the large amount of sludge accumulated at the bottom of the breeding pond It contains a lot of bait residues that have not been swallowed by sea cucumbers. After soaking for a long time, it is easy to form granular loose matter, which floats in the seawater without direction, seriously affecting the light transmittance of seawater in the culture pond, and it is very easy to cause sea cucumbers. , affect the normal growth of sea cucumber

Therefore, sea cucumber circles or sea cucumber cofferdams must be cleaned regularly. However, regular bottom cleaning of sea cucumber circles or sea cucumber cofferdams is a very time-consuming and labor-intensive task. Sea cucumber bait is a thing worth studying
