Embodiment 1

[0026] Such as figure 1 As shown, the filter bed type cultivation system of the present invention includes a cultivation pond 1, and the area of ​​the cultivation pond 1 can be set according to actual needs, with an area of ​​5 to 100m 2 , the bottom of the culture pond 1 is provided with an overhead layer 2, on which the sand layer filter bed 3 is laid, and above the sand layer filter bed 3 is an aquaculture water layer 8; One end of the airlift pipe 4 is connected to the bottom of the culture pond 1, and the other end of the airlift pipe 4 is connected to the top of the culture water layer 8; the bottom of the culture pond 1 is provided with the first aeration pipe 5, and the bottom of the culture water layer 8 There is a second oxygen increasing pipe 6, and the two together form a three-dimensional oxygen increasing system. The first oxygen increasing pipe 5 passes through the sand filter bed 3 through the PVC pipe 7 and is connected to the external air pipe. The second oxy...

Embodiment 2

[0032] Embodiment 2: Shrimp enters the pond and increases oxygen.

[0033] Put prawns in the filter bed culture system, the size is 3-4cm, and the density is 100-300 tails / m 2 , The shrimp at this time has the habit of diving into the sand, and the compound feed is fed at 6% of the feeding amount.

[0034] During oxygenation, the oxygenation and disturbance of the overhead layer 2 can prevent the water body below the overhead layer 2 from forming a still water dead angle; the dissolved oxygen in the aquaculture water layer 8 can reach more than 5mg / L, and sufficient oxygenation will help the water body (comprising the overhead) Oxidative decomposition of organic matter in the water body below layer 2).

[0035] In addition, open the airlift pipe 4, due to the rising water effect of the airlift pipe 4, dissolved oxygen in the water body of the culture water layer 8 enters the sand layer 31 and makes the sand layer 31 an oxygen-enriched sand layer, avoiding the formation of an an...

Embodiment 3

[0036] Example 3: Adhesion and efficient decomposition of probiotics.

[0037] Probiotics such as bacillus, lactic acid bacteria and photosynthetic bacteria are added to the culture pond 1. When the filter bed culture system is running, the probiotics in the culture water layer 8 are continuously infiltrated into the sand layer 31, which improves the adhesion efficiency of the probiotics , so that the sand layer filter bed 3 becomes a probiotic bed; at the same time, the attached probiotics degrade and utilize the residual bait and feces through biodegradation, promote the proliferation of probiotics, increase the stabilization effect of the probiotic bed, and improve the decomposition efficiency of the residual bait and feces. Avoid sand layer 31 blackening.

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...
