Abstract

The invention discloses a plastic bag aquaculture technology, which belongs to fish culture of livestock and aquaculture. The classification number is A01K61/00. Plastic bags with upper openings are laid above open water, such as lakes, water reservoirs, river ways or oceans, aquatic products, such as fishes and shrimps, are cultured in the bags, and aquaculture water is isolated from peripheral water, so as to prevent the cross contamination between the aquaculture water and the peripheral water. Garbage precipitate in the bags are collected through sewage collecting pipes and sewage collecting tanks and are not discharged into the peripheral water. The aquaculture technology does not pollute water, such as lakes, water reservoirs, river ways and oceans, and can also prevent the peripheral water from being suddenly polluted, so that the aquaculture water can not be affected.

Description

A kind of plastic sack aquaculture technology

One, technical field: animal husbandry and fishery fish culture A01K61/00.

Two, background technology: pool cultivation is mainly dug at present aquaculture on land, or in the lake, waters purse seine or the cage cultures such as reservoir, river course and ocean.Purse seine and cage culture water body communicate with the water body of net outside, like this, and the water body around breeding water body has polluted.So in order to protect the water quality in the waters such as reservoir, lake, river course and ocean, at present, seining cultivation and cage culture are subject to strict restriction, some is local even strictly forbid.

Three, summary of the invention: the present invention floats over lake, reservoir, river course or ocean with the plastic sack of top opening, the aquatic products such as culturing fish and shrimp in plastic sack, and the outer water body of the breeding water body in the bag and bag separates, and inside and outside water body does not circulate mutually, does not pollute mutually.Like this, both saved the soil, again water bodys such as polluted lake, reservoir, river course or ocean not.In addition, can also prevent from affecting because of the peripheral water body burst pollution of net cage event the aquatic products of cultivation.

Four, description of drawings: 1 is the bag made from plastic foil among the figure, and aquaculture water and peripheral lake water are isolated in the bag;

2 is to use the foamed plastics filling around the sack upper limb among the figure, and bag is floated; 3 is the dirty pipes of collection among the figure; 4 is sludge collecting box among the figure; 5 is lake water among the figure.

Five, embodiment:

Example one: shown in " Figure of description ", be that 0.5 millimeter PVC geomembrane is made the round plastic bag, 2 meters of diameters, dark 2 meters of bag with thickness, bag is placed in the lake, fill with lake water, after the outer liquid level of inner bag maintained an equal level, about 10 centimetres of sack Edge preserving surfaced, in the lake, play two stakes, the cultivation bag is tied down, in case waft, in bag, support Tilapia mossambica.Allow bag interior breeding water body rotation 1 hour every day, impel sediment in the breeding water body to accumulate in the center bottom of bag, the dirty pipe of collection end is put into bottom the sludge collecting box, utilize siphonage, sediment flows into sludge collecting box automatically, after sediment flows to end, the terminal perk of the dirty pipe of collection, exceed liquid level and get final product.

Example two: shown in " Figure of description ", be that 1.0 millimeters HDPE geomembrane is made oval plastic sack with thickness, 100 meters of long diameters, 80 meters of short diameters, dark 4 meters of bag, bag is placed in the lake, fills with lake water, after the outer liquid level of inner bag maintains an equal level, keeping the sack edge has 12 centimetres to surface approximately, in the lake around the cultivation bag, play about 36 stakes, the cultivation bag is tied down, in bag, support Penaeus Vannmei.Collect the sediment in the cultivation bag every day, the dirty pipe of collection end is put into the sludge collecting box bottom, utilize siphonage, sediment flows into sludge collecting box automatically, after sediment flows to end, the terminal perk of the dirty pipe of collection, exceeds liquid level and gets final product.Transport on the bank with the sediment of water in the sludge collecting box, isolate supernatant and return breeding water body, sediment is as organic manure.

Claims

1. feature of the present invention is the plastic sack of opening on the open water surface such as lake, reservoir, river course and ocean is placed, and carries out aquaculture in bag, and the outer water body isolation of breeding water body and bag in the bag prevents that breeding water body and bag outer water body from polluting mutually.

2. based on claim 1, with material fillings such as foamed plastics or plastics empty bottles, in order to keep sack up, and allow the whole plastic sack that comprises breeding water body keep afloat around the plastic sack edge suitable for reading.

3. based on claim 1, the waste precipitate in the plastic sack in the breeding water body is by collecting the concentrated sludge collecting box that is discharged into of dirty pipe.
