Embodiment 1

[0032] In this embodiment, a seawater factory workshop ecological breeding technology is selected, a typical factory workshop cement breeding pond 6m×6m×1m is selected for transformation, the pond depth is 0.8m, and a 4m×4m×0.4m PVC is built in the culture pond Shelves, the weights of various organisms are: moiré gentian grouper (average weight of individual 300g) 300kg, macroalgae selected Gracilaria platyphylla 25kg, benthic shellfish selected four-cornered clam 15kg, benthic diatom selected core Algae stock solution (10 6 Pieces / ml) 1500ml.

[0033] The key points of the ecological breeding technology in this embodiment:

[0034] 1) Workshop transformation: The roof of the large shed in the breeding workshop is transformed into a sunshine board, and the light transmission of the sunshine board needs to be adjusted according to the season, so that the strongest light intensity on the breeding water surface is between 2500~3000lx; the breeding pond is built 4m×4m×0.4 The mPVC she...

Embodiment 2

[0040] In this example, the ecological farming technology of the seawater factory workshop is to choose a typical factory workshop farming cement pond 6m×6m×1m, the pond water depth is 0.8m, and the transformation is carried out, and a 4m×4m×0.4m PVC shelf is built in the culture pond. The weight of each kind of creatures put into the rack is: 300kg of Moiré gentian grouper with an average weight of 400g, about 750 pieces, 25kg of macroalgae selected from Rhodophyta, 15kg of benthic shellfish from Philippine clam, and benthic silica Algae selection costal alga stock solution (10 6 Pieces / ml) 1500ml.

[0041] The key points of the ecological breeding technology in this embodiment:

[0042] 1) Workshop transformation: The roof of the large shed in the breeding workshop is transformed into a sunshine board, and the light transmission of the sunshine board needs to be adjusted according to the season, so that the strongest light intensity on the breeding water surface is between 2500~3...

Abstract

The invention relates to an ecological culture technology for a seawater industrial workshop and belongs to the technical field of aquaculture. By reforming a prior seawater industrial culture workshop, the strongest illumination of a culture water surface is controlled between 2500lx-3000lx, a PVC rack with a size of 4m*4m*0.4m is built in a culture pond (6m*6m*1m, the water depth is 0.8m), 300-450kg of swimming fishes, 20-30kg of large algae and 10-20kg of benthic shellfish are stocked in the pond, the ratio of nitrogen to phosphorus to iron to silicon in the water body is adjusted to be 10-25:1-2.5:0.1:1-2.5, and a benthic diatom stock solution (106/ml) of 1000-2000ml is introduced. only fish feed is put into the whole culture process, ammonia nitrogen in the culture process is degradedby using the large algae, and oxygen is generated for biological utilization; the benthic diatom is utilized to degrade residual bait and excrement and simultaneously provides bait for benthic shellfish; the whole system achieves the recycling of nutrients and the self-purification of the culture process under a static water culture condition.

Description

1. Technical Field [0001] The present invention is an ecological breeding technology in a seawater factory workshop, specifically, it is a way to construct a regional nutrient ecological breeding system mainly focusing on fish farming by transforming the existing seawater factory breeding workshop, optimizing organisms of different niches, and At the same time of aquaculture production, it realizes the recycling of nutrients and the self-purification of aquaculture, which belongs to the field of aquaculture technology. 2. Background technology [0002] Factory farming is one of the more common farming models in coastal areas of my country, and it is also the most important intensive farming model for marine aquaculture. At present, the scale of factory farming of marine fish in my country has exceeded 7 million m 2 , Calculated on the basis of 5 water changes per day, the daily aquaculture wastewater discharge exceeds 10 million m 3 , Equivalent to the storage capacity of a mediu...
