The device for temporarily raising the false caught wild Chinese sturgeon parr is composed of a cultivation water tank, a temperature control device and a water filtering and purifying device, and is characterized in that the cultivation water tank uses a 2 m * 1.2 m * 0.8 m water tank; the inner surface is actinic; on side of the bottom of the water tank is provided with a sewage outlet and has 2 percent slope drop; the cultivation water tank is provided with a cold water machine the power of which is 1 HP; an water inlet of the cold water machine is connected with a water outlet of the water filtering device; the water filtering and purifying device is composed of a biological purification device and a filtering device, wherein, the specification of the biological purification device is 0.4 m * 0.5 m * 0.3 m; biological balls and complex microbiological preparations are placed in the biological purification device; the specification of the filter device is 1 m * 0.5 m * 0.3 m; water is led to the filtering device by a small diving pump arranged in the water tank; filter cotton, orlon cotton, coral sand and active carbon are positioned in the filter device. The device for temporarily raising the false caught wild Chinese sturgeon parr is used for temporarily raising the wild Chinese sturgeon parr.

Description

Mistake is caught wild mandarin sturgeon juvenile fish and is supported device temporarily
Technical field:
The utility model relates to aquaculture device.
Background technology
Mandarin sturgeon is bottom activity fish, the property strong trip, bigger water body helps its growth, but because be high temperature season 5~September that mandarin sturgeon more often occurs, outdoor ponds is exposed to the sun by the sun, and water temperature reaches more than 30 ℃, and the suitable growth temperature of mandarin sturgeon is 20~25 ℃, food ration will reduce more than 28 ℃, and growth rate is slowed down, and can cause death in the time of more than 35 ℃.Bigger owing to pond waters simultaneously, regulating and controlling water quality and bait throwing in be manageability not, so outdoor ponds is not suitable as the temporarily foster facility that wild mistake is caught the mandarin sturgeon juvenile fish.
The mandarin sturgeon juvenile fish is higher to water quality requirement, dissolved oxygen especially, and the mandarin sturgeon juvenile fish is suffocated and a little is 2mgO 2About/L, general fish exceed a lot.Cultivating condition generally requires dissolved oxygen to be higher than 6mg/L, ingests this moment and grows normally, and dissolved oxygen is lower than 4mg/L, the minimizing of ingesting; When dissolved oxygen was reduced to 3~3.5mg/L, ingesting stopped; When dissolved oxygen is low to moderate 2~2.5mg/L, cause death by suffocation.Ammonia nitrogen and non-ionic ammonia that fish body excreta in the breeding water body and the decomposition of residual bait simultaneously produced produce very big harm to the mandarin sturgeon juvenile fish, generally require ammonia nitrogen concentration<0.5mg/L in the water body, non-ionic ammonia<0.02mg/L.Therefore existing general indoor culture facility is difficult to satisfy the demand that wild rescue mandarin sturgeon juvenile fish is supported temporarily, needs a kind of new cultivator of exploitation.
The utility model content
The problem that the utility model need solve is according to ecological habit of mandarin sturgeon juvenile fish and requirement, exploitation one cover is fit to the device that wild mandarin sturgeon juvenile fish is supported temporarily, can be by temperature regulating device and water filtration purifier, the water quality that keeps culturing tank remains at the suitableeest state, improves survival rate and the growth rate of mandarin sturgeon juvenile fish.
The technical solution of the utility model is made up of breed tank, temperature regulating device, water filtration purifier, it is characterized in that culturing tank and adopts 2m * 1.2m * 0.8m tank, and inner surface is photochemical, and bottom of gullet one side is established a sewage draining exit, and 2% gradient is arranged; The cooling-water machine of culturing a 1HP power of tank outfit is as temperature regulating device, and the water inlet of cooling-water machine is connected on the delivery port place of water filtering device; Water filtration purifier adopts biological purification plant and filter to form, and the biological purification plant specification is 0.4m * 0.5m * 0.3m, and biological ball and complex microorganism preparations are placed in the inside, by the effect of biological ball surface biological film, play the effect that purifies water; The filter specification is 1m * 0.5m * 0.3m, by the little immersible pump that is provided with in the tank water is imported filter, places filter cotton, polyacrylonitrile fibre, coral sand and active carbon in the filter respectively, and is middle with netted dividing plate separation.
The utility model is cultured the tank water temperature and is can be controlled in 20~25 ℃, dissolved oxygen is higher than 6mg/L, ammonia nitrogen concentration<0.5mg/L in the water body, non-ionic ammonia<0.02mg/L, being fit to wild mandarin sturgeon juvenile fish supports temporarily, by temperature regulating device and water filtration purifier, can keep culturing the suitableeest state of water quality of tank, have the survival rate of raising mandarin sturgeon juvenile fish and the advantage of growth rate.
Description of drawings
Fig. 1 supports the device schematic diagram temporarily.
Fig. 2 is the water filtration purifier schematic diagram.
Embodiment
This device (see figure 1) partly is made up of breed tank a, temperature regulating device b, water filtration purifier d three, and the concrete technical parameter of each several part is as follows:
Culture the tank of tank a (Fig. 1) employing 2m * 1.2m * 0.8m specification, material is fiberglass or PVC, and inner surface is photochemical, and bottom one side is established a sewage draining exit e, and 2% gradient is arranged.
Temperature regulating device b (Fig. 1) adopts each to culture the cooling-water machine that tank is equipped with a 1HP power, and the delivery port m (Fig. 2) that the water inlet of this cooling-water machine is connected on water filtration purifier locates.
The water filtration purifier (see figure 2) is divided into 2 parts, and promptly biological purification plant and filter are the PVC material.
The dimensions of biological purification plant (Fig. 2) is 0.4m * 0.5m * 0.3m, and biological ball k and complex microorganism preparations are placed in the inside, by the effect of biological ball surface biological film, plays the effect that purifies water.
The dimensions of filter (Fig. 2) is 1m * 0.5m * 0.3m, by the little immersible pump c (Fig. 1) that is provided with in the tank water w is imported filter, be divided into 4 lattice in the filter (Fig. 2), be placed with filter cotton f, polyacrylonitrile fibre g, coral sand h and active carbon j respectively, middle with netted dividing plate separation.
