Description
Technical field
The present invention relates to the Cultivating techniques of a kind of biological feed, specifically a kind of brachionus plicatilis artificial water circulation high-yield cultivating system and breeding method.
Background technology
Brachionus plicatilis (Brachionus plicatilis) be distributed widely in all kinds of light, the salt water water body such as lake, pond, rivers, coastal waters, the proliferative speed being exceedingly fast because of it, volume of production is the highest, significant in the research of ecosystem structure, function and biological productivity.Wheel animalcule in ocean about kind more than 50, they majorities live in littoral neritic area.Mass propgation can be carried out in sea-farming, and a kind of for the only brachionus plicatilis of marine animal artificial breeding.Brachionus plicatilis has that adaptive faculty is strong, growth is fast, the travelling feature such as slowly, is suitable for extensive artificial culture, is many indispensable open-mouthed baits of economic animal germling.
Due to the needs of industry development, the seed industry such as artificial crab seedling rearing needs large number of biological bait, and traditional breeding method can not meet Production requirement, and therefore increasing substantially culture of rotifera, to cultivate yield significant to the development of crab and related industry.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of brachionus plicatilis artificial water circulation high-yield cultivating system and breeding method, it is capable of the high-yield cultivating of brachionus plicatilis, meets aquaculture demand.
The technical scheme provided according to the present invention: brachionus plicatilis artificial water circulation high-yield cultivating system, it is characterized in that: include intake pool, rotifer breeding ponds, Ji Chongchi, insect-catching pond and lift pump, described rotifer breeding ponds is at least one, rotifer breeding ponds one end is provided with water inlet, the other end is provided with discharge outlet, rotifer breeding ponds is connected with intake pool by its water inlet, and rotifer breeding ponds is connected with Ji Chongchi by its discharge outlet；Described Ji Chongchi is provided with insect-catching mouth, and Ji Chongchi is connected with insect-catching pond by its insect-catching mouth；Described insect-catching pond is connected with intake pool by lift pump, and lift pump is for extracting the water in insect-catching pond to intake pool.
As the further improvement of described culture system, described rotifer breeding ponds has multiple, and multiple rotifer breeding ponds line up two rows symmetrical；Between two described row's rotifer breeding ponds, Ji Chongchi is set, the outside of two row's rotifer breeding ponds respectively arranges an intake pool, the intake pool of every side surrounds at least both sides of respective side rotifer breeding ponds, described insect-catching pond is arranged on collection one end, worm pond, Ji Chongchi is separated by partition wall with insect-catching pond, be furnished with many communicating pipes on partition wall as insect-catching mouth, both sides, insect-catching pond respectively with the end abutment of two intake pools, lift pump is arranged on the both sides sidewall in insect-catching pond.
As the further improvement of described culture system, the single area of described rotifer breeding ponds is 5～10 mu, and the degree of depth of rotifer breeding ponds is 1.0～1.2m, and the depth of water in rotifer breeding ponds is 0.8～1.0m, and each rotifer breeding ponds sets 1 water inlet and 2 discharge outlet；The width of described Ji Chongchi is 8～10m, the deep 0.2m of depth ratio rotifer breeding ponds of Ji Chongchi, is 1.2～1.4m；The width in described insect-catching pond is 8～10m, the deep 0.6m of depth ratio rotifer breeding ponds in insect-catching pond, is 1.8～2.0m, and described insect-catching mouth is arranged at the depth under water 1.0m of Ji Chongchi；The width of described intake pool is 1～2m, and the degree of depth of intake pool is 0.4m, the bottom of intake pool and the highest water surface hold the line of rotifer breeding ponds.
