Abstract
The invention discloses an artificial breeding method of tachysurus fulvidraco. The artificial method mainly includes the following steps that firstly, pond conditions are selected, wherein the area of a pond is 8 to 10 mu, the water depth is 1.8 m to 2 m, and quicklime pond cleaning and disinfecting are carried out in the pond before the tachysurus fulvidraco fries are cast; secondly, casting of the tachysurus fulvidraco fries is performed, wherein 6000 to 7000 tachysurus fulvidraco fries per mu are cast and bred in April, feed is cast for feeding from the last ten days of April to November, the conventional feed selected each time is cast according to 1.5 percent to 3 percent of the weight of the tachysurus fulvidraco fries, and the feed is cast twice every day; thirdly, the water quality of the pond is guaranteed; biological agents are used for regulating the water quality once a month from June to September, the amount of the biological agents used each time is 500 g to 1000 g per mu, water is not replaced in the first month and is replaced one to two times after one month, and water which is 10 centimeter to 20 centimeter in depth is replaced each time; fourthly, breeding and oxygenation are performed, wherein one aerator is added to the pond area of every three mu, and the aerators are turned on for oxygenation two hours before each time of feed casting during June to September. According to the artificial breeding method of the tachysurus fulvidraco, the sufficient oxygen content of the pond can be kept, the feed intake amount of the tachysurus fulvidraco fires is increased, in addition, harmful matter in the water can be evaporated while oxygenation is carried out in the pond, and therefore the water quality is adjusted.
Description
Technical field
What the present invention relates to is the artificial cultivating method of a kind of yellow cartfish, belongs to Technique in Fishes cultural technique field.
Background technology
Yellow cartfish is subordinate to Silurformes in classification, Nian section, although its individuality is less, its meat flavour is delicious, nutritious, gets consumer reception very much; Based on this, developed in recent years Culture of Pelteobagrus Fulvidraco new technology, specifically comprise following content:
A, pond condition: 3-5 mu of areas, 1.5-2 meters of the depth of waters, pond requires irrigation and drainage convenient, and the water yield is sufficient; Before fingerling lower storage reservoir, with quicklime, clean up the pond sterilization thoroughly to remove wild fishes class and to kill causal organism;
The input of b, fingerling: the input of fingerling can be supported and join to support and carry out in proportion according to main, and the specification of putting in a suitable place to breed is unsuitable too small;
C, feedstuff feeding and management: available pure animal feed, as small fish, shrimp, earthworm etc., also can use manufactured feed, require protein content 38-40%, lipase 37-8%, vitaminize;
D, daily management: the more conventional fish of yellow cartfish hypoxia-resistant capacity is poor, happiness clean water, therefore, the pond water transparency of cultivation yellow cartfish should remain on 35-40 meters, and the pond that breeding density is high should be established aerator and be prevented anoxic floating head, the new water of regularly annotating.
Although above-mentioned Culture of Pelteobagrus Fulvidraco new technology is widely promoted, technology maturity is considerably high, with regard to fish culture, also has the problems such as this fanning economics is not high enough, and aquaculture cost is large.
Summary of the invention
The object of the invention is to overcome the defect existing in prior art, and provide a kind of on existing artificial culture technology basis, can further reduce and propagate cost artificially, cultivation efficiency is provided, the artificial cultivating method of the yellow cartfish of fanning economics is provided.
The object of the invention is to complete by following technical solution, the artificial cultivating method of described yellow cartfish, it mainly comprises: a, select pond condition: select 8-10 mu of pond areas, 1.8-2 meters of the depth of waters were first carried out the quicklime sterilization of cleaning up the pond to pond before advanced fry of yellow catfish is thrown in; The input of b, advanced fry of yellow catfish: put advanced fry of yellow catfish 6000-7000 tail/mus in a suitable place to breed in April, the nursing that feeds intake late April to November selects conventional feed to feed intake according to the body weight of yellow cartfish 1.5-3% at every turn, feeds intake every day twice; C, pond water quality guarantee: in 6-September, monthly once use biological agent regulating water quality, each biological agent consumption is at 500-1000 grams/acre, and water is not changed in the junior one month; Within one month, change water 1-2 times later, change 10-20 centimeters of depth of waters of water at every turn; D, cultivation oxygenation: every 3 mu of pond areas are established an aerator, and during 6-September, start oxygenation in two hours before at every turn feeding intake, it can not only make pond keep sufficient oxygen content, increase the food-intake of yellow cartfish, and can also issue additional the unfavorable material in water when giving pool oxygenation, and then regulating water quality.
Biological agent of the present invention is EM bacterium or photosynthetic bacteria.
Existing common cultural technique be every mu cultivation more than 10000 mu, an aerator is established in 5-8 mu of ponds, and the oxygenation time is irregular.
Yellow cartfish cultivation of the present invention is put seedling quantity lower than common cultivation, take every 3 mu to establish an aerator, and start oxygenation in 2 hours before the feed of throwing something and feeding, to make pond keep sufficient oxygen content, and then can increase the food-intake of yellow cartfish, and can keep yellow cartfish to have enough time of having a rest, be similar to existing instant chicken cultural method, can shorten listing in 30 days the vegetative period of its more existing common yellow cartfish cultivation, and feed coefficient reduces by 10-15%.
