Filter bed breeding system and factory breeding method of buried-dwelling marine organisms

Abstract

The invention discloses a filter bed breeding system and a factory breeding method of buried-dwelling marine organisms, and belongs to the field of aquiculture. The breeding system comprises a breeding pond, an empty space is arranged at the bottom of the breeding pond, a sand layer filter bed is arranged on the empty space, and a breeding water layer is above the sand layer filter bed; the breeding pond is internally provided with an air-life tube, one end of the air-lift tube communicates with the bottom of the breeding pond, and the other end of the air-lift tube communicates with the breeding water layer; a first oxygen increasing tube is arranged at the bottom of the breeding pond; and a second oxygen increasing tube is arranged at the bottom of the breeding water layer. S and divinghabits of the buried-dwelling marine organisms such as Marsupenaeus japonicus and Babylonia can be satisfied, the problem of bottom substrate changing black during high-density breeding is advantageously solved, the adhesion and purification effect of probiotics are improved, breeding stability is improved, the filter bed breeding system and the factory breeding method of the buried-dwelling marine organisms are suitable for high-density factory breeding of the buried-dwelling marine organisms, and has a good application prospect.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a filter bed type culture system and a factory culture method for buried marine organisms. Background technique [0002] Buried marine organisms such as Penaeus japonicus and Dongfeng snails have the habit of submerging in the sand. The residual bait and feces during the long-term breeding process will be deposited on the sand surface, which will cause the sand to blacken, cause the growth of pathogens, and cause serious diseases such as black gill disease of prawns. Diseases cause huge economic losses every year. How to improve the decomposition ability of residual bait feces and avoid the breeding of pathogens caused by sand blackening in the process of breeding buried marine organisms is a major technical problem that needs to be solved urgently in the process of industrialized breeding of buried marine organisms. [0003] Throughout the history of technological development to solv...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the above-mentioned problems in the prior art, to provide a filter bed type cultivation system and a factory culture method for buried marine organisms, which can meet the needs of buried marine organisms such as Penaeus japonicus and Dongfeng snails. The living habit of submerging sand also helps to reduce the problem of substrate blackening in the process of high-density culture, improve the effect of probiotic adhesion and purification, and improve the stability of culture. It is suitable for high-density factory culture of buried marine organisms and has a relatively high good application prospect
