Problems solved by technology

[0009] The present invention aims to solve the problem that the pond bottom sludge treatment method in the prior art must be realized after the cultivation is completed and the effect of only chemical, biological or physical methods is not good, and provides a resource-based method for increasing the concentration of pond bottom sludge. The efficient breeding method can restore the pond sediment during the cultivation process without affecting the normal cultivation, effectively control the generation and accumulation of toxic and harmful substances, and realize the recycling of nutrients (nitrogen, phosphorus, etc.) in the pond water and sediment. Use to increase pond productivity

Embodiment 1

[0038] A kind of synergistic breeding method for resourceful treatment of bottom mud in intensive culture ponds, comprising the following steps:

[0039] A. Collocation of breeds

[0040] Carry out polyculture according to the ratio of omnivorous fish and filter-feeding fish at 5:1;

[0041] B. Sediment resource treatment

[0042] When the transparency of the pond water body is 30cm, stir the water body, extract the bottom mud, lift it up and expose it to the upper water body or the air, and treat it once every 5 days; when the water body transparency is 42cm, treat it once a day for 2 consecutive days; The treatment is carried out between 12:00-14:00 on the same day; while the treatment is being carried out, strong oxidizing substances and micro-ecological agents are splashed into the water body to fully oxidize the organic matter in the sediment.

[0043] C. Use of oxygenation facilities

[0044] Set the microporous nanotube aerator in the bait feeding area of ​​the pond;...

Embodiment 2

[0046] A kind of synergistic breeding method for resourceful treatment of bottom mud in intensive culture ponds, comprising the following steps:

[0047] A. Collocation of breeds

[0048] Carry out polyculture according to the ratio of omnivorous fish and filter-feeding fish at 5:2;

[0049] B. Sediment resource treatment

[0050] When the transparency of the pond water body is 40cm, stir the water body, extract the bottom mud, lift it up and expose it to the upper water body or the air, and treat it once every 7 days; when the water body transparency is 50cm, treat it once a day for 3 consecutive days; The treatment is carried out between 12:00-14:00 on the same day; while the treatment is being carried out, strong oxidizing substances and micro-ecological agents are splashed into the water body to fully oxidize the organic matter in the sediment.

Abstract

The invention relates to a synergistic aquaculture method for resource-based treatment of bottom sludge in intensive cultivation ponds, and belongs to the technical field of aquaculture. The method of the invention includes the matching of cultured species, the resource treatment of sediment and the use of oxygenation facilities. According to the present invention, the ratio of omnivorous fish and filter-feeding fish is 5:1-5:2 for polyculture, and then adopts a specific method to process sediment resources during the breeding period, and finally adds specific oxygen-increasing facilities. These three links interact with each other to recycle the sediment nutrients, so as to achieve the goal of breeding efficiency. On the one hand, the original function of the sediment is restored, and the oxidation state is restored. On the other hand, the organic matter is oxidized to reduce the oxygen debt and the probability of disease outbreak. Moreover, the purpose of increasing production and income can be achieved without adding too much material.

Description

technical field [0001] The invention relates to a method for synergistic cultivation of intensive cultivation ponds, more specifically, the present invention relates to a method for synergistic cultivation of bottom mud of intensive cultivation ponds as resources, and belongs to the technical field of aquaculture. Background technique [0002] Except for 20-30% of the nutrients such as nitrogen and phosphorus input in the pond breeding process, which are absorbed and utilized by the breeding organisms, the remaining 60-70% are all deposited in the bottom mud of the pond, and the drugs and chemicals input in the breeding process are also in the water body or deposits in sediment. Therefore, due to the large amount of organic matter in the bottom mud of the breeding pond, the lower layer of the pond water body is hypoxic for a long time and is in a reduced state. It is like a time bomb, which may cause ammonia nitrogen, nitrite, methane, hydrogen sulfide and other toxic and ha...
