According to the method, rich water and floating feed are matched for breeding paddlefishes and a water quality environment is monitored, and therefore the method has the advantages that management is convenient, feeding is convenient, the nutritive value of the bred paddlefishes can be effectively guaranteed, and the survival rate of the paddlefishes is high.

Description

Paddlefish cultural method

Technical field

The present invention relates to technical field of aquaculture, be specifically related to a kind of paddlefish cultural method.

Background technology

Paddlefish, is commonly called as duckbilled sturgeon, originates in the U.S., its delicious meat, nutritious, and the caviar made with its ovum is nutriment famous and precious in the world; Another have duckbilled the same long kiss, unique build because of it, and be also a kind of famous and precious fancy fishes, feeding habits are wide, and can ingest plankton, the insect larvae in water of also can ingesting, water earthworm and artificial feed.In the prior art, usually there is the defect that paddlefish cultivation survival rate is low, management is inconvenient.

Summary of the invention

The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of paddlefish cultural method that convenience manages, paddlefish survival rate is high is provided.

Paddlefish cultural method provided by the invention, comprises the following steps:

(1), pond is selected: select area to be 1 ~ 3 mu, the pond that the depth of water is 1.5 ~ 2 meters, offers water inlet and discharge outlet in pond, water inlet and discharge outlet place set up defences and escape net;

(2), pond is cleaned: Jiang Chishui drains, and levels after at the bottom of pond, carries out disinfection to pond with the quicklime of 70-100 kg/acre;

(3), sundries fishing removes: inject new water, and skim the foreign material in pond;

(4), sterilization paddlefish: embathe paddlefish fingerling 15 ~ 20 minutes with the saline solution of 2.5% ~ 3% or the bleaching fluid of 0.001%;

(5), throw in paddlefish: the density dropping into 3-5 tail by every cubic metre of water body, in pond, drop into the paddlefish fingerling of more than 6 centimetres;

(6), rich water: the 5-8 days after paddlefish fingerling enters pond, soya bean of splashing every day slurry 3-5 kg/acre;

(7), bait is prepared: prepare the buoyancy feed that protein content is more than 30%;

(8), throw in bait: bait 3-4 time of throwing something and feeding every day, daily ration of feeding by the 4-5% of nursing paddlefish gross weight;

(9), daily management: every circumferential pond adds new water once, and the 20cm that at every turn adds water is dark; Every first quarter moon carries out disinfection to pond; Monthly to pond water quality analysis once, the water quality pH keeping pond is 7.5-8.5, water temperature is 20.0-31.0 DEG C, non-ionic ammonia≤0.02mg/L, total alkalinity is 1.00-2.00mmol/L, dissolved oxygen >=5.0mg/L, transparency is 28-32cm, chemical oxygen consumption (COC)≤15mg/L, biochemical oxygen demand (BOD)≤5mg/L, total Escherichia coli < 5000/L.

The present invention utilizes rich water to coordinate buoyancy feed to raise paddlefish, with the monitoring to water quality environment, is not only convenient to management, throws something and feeds conveniently, and effectively can guarantee the nutritive value of raising paddlefish, and has the high advantage of paddlefish survival rate.
