The zero-discharge fish-shrimp mixed-culturing system has the main advantages that the high density cultivation of litopenaeus vannamei is achieved, and cultivation management is facilitated; water purification capacity is high, and the water discharging frequency is low; same-pool mixed culturing of litopenaeus vannamei and carnivorous fishes is achieved.

Production line device for large-scale environmental protection of eel
ActiveCN107027678BAchieve recyclingProtect environmentClimate change adaptationPisciculture and aquariaProduction lineFinless eel
The invention relates to a production line device for large-scale and environment-friendly finless eel culture. The production line device comprises an annular base frame, an annular rotating disc rotationally connected to the base frame, a rotation driving device used for driving the rotating disc to rotate around the center of the base frame, a PLC control panel, multiple finless eel culture net cages, a feeding operation platform, a culture water recovering pond, a discharging and collecting pond, a water injection device, a net cage washing pond, a culture water purifying pond and a water injecting and taking pond. The multiple finless eel culture net cages are uniformly hung at the outer side of the rotating disc in the circumferential direction, the feeding operation platform, the culture water recovering pond, the discharging and collecting pond, the water injection device and the net cage washing pond are sequentially distributed on the periphery of the rotating disc in the clockwise direction, and the feeding operation platform, the culture water recovering pond, the discharging and collecting pond and the net cage washing pond are correspondingly located below the finless eel culture net cages. By means of the production line device, large-scale culture can be conduct on the ground conveniently, culture water can be recycled, culture management and fishing are convenient, and efficiency is high.

Artificially breeding method for Lutraria maximae
InactiveCN102077789BImprove survival rateFast growthClimate change adaptationPisciculture and aquariaDiseaseShallow sea
The invention discloses an artificially breeding method for Lutraria maximae. The traditionally breeding method for Lutraria maximae has a relatively low survival rate because breeding location cannot be changed after Lutraria maximae are bred and raised in shallow sea, and clearing work for breeding Lutraria maximae is difficult to develop. During red tide or disease period, the location cannot be cleared up and the breeding location cannot be transferred. People can only put hopes on the disease resistant ability of Lutraria maximae and passively watch, without any active defense and measurement, which is the reason why Lutraria maximae have a relatively low survival rate during breeding. With five measures, such as selection of breeding box, choice of seed, breeding of seed, managementof breeding and harvest of adult shellfish, the artificially breeding method for the Lutraria maximae provided by the invention improves the breeding survival rate which reaches 90 to 98 percent, ensures a high speed of growth and reduces a breeding period which is shortened by 3 to 8 months compared with the traditionally breeding method. By the method, the management of breeding is convenient, a strong ability of resisting enemies is obtained, and adult shellfishes are convenient to harvest.

Nutrient soil with good slow release performance
InactiveCN106588513APromote growthDoes not affect ecological functionCalcareous fertilisersMagnesium fertilisersPotassiumManganese
The invention discloses a kind of nutrient soil with good slow release performance. The nutrient soil comprises, by weight, 80-100 parts of canal mud, 4-10 parts of calcium ammonium nitrate, 2-9 parts of guano, 1-8 parts of flue ash potassium fertilizer, 0.2-0.6 part of ferric humate, 0.1-0.2 part of EDTA manganese chelate, 0.04-0.09 part of zinc sulfate, 0.1-0.45 part of wollastonite powder, 2-4 parts of borax, 2-6 parts of sepiolite, 10-20 parts of meat and bone meal, 2-8 parts of germinated brown rice, 2-8 parts of cassava dregs, 10-30 parts of composted chicken manure and 5-15 parts of modified activated carbon. The nutrient soil can provide a large number of nutrient substances for plants and promote plant growth without influence on the ecological function of plants, is good in viscosity and dispersibility and low in cost, can release nutrients slowly and everlastingly through combination with growth characteristics and fertilizer requirement laws of plants, and is remarkable in slow release effect.
