Abstract
The invention discloses a breeding method for inter-breeding loaches in chalcalburnus chalcoides aralensis. The breeding method includes steps of 1) selecting, cleaning and disinfecting a pond; 2) breeding fry outside; 3) feeding; 4) managing water quality; 5) preventing and controlling diseases; 6) fishing. The chalcalburnus chalcoides aralensis are bred on the upper layer, and the loaches are on the bottom layer. By the aid of the method for inter-breeding the loaches in the chalcalburnus chalcoides aralensis, breeding yield, specifications and quality of the chalcalburnus chalcoides aralensis are not only unaffected but water body space is sufficiently developed and utilized, breeds of the pond are increased, and the environment of the water body is improved. Compared with a method for breeding the chalcalburnus chalcoides aralensis singly, yield is increased by more than 30%, benefits are increased by more than 20%, and economic earnings of breeders are increased.
Description
Technical field
The present invention relates to technical field of aquaculture, be specifically related to the cultural method that loach supported by a kind of Chalcalbumus chalcoides aralensis cover.
Background technology
Chalcalbumus chalcoides aralensis (Chalcalburnus Chalcoides aralensis) is subordinate to Cyprinidae, Chalcalbumus chalcoides aralensis belongs to, it is European and that Central Asia is famous and precious small-sized rare economic fish, calendar year 2001 introduces China first, there is build fitness, without thorn, meat exquisiteness, delicious flavour between flesh, the feature such as nutritious, harvesting rate is high, degeneration-resistant and strong adaptability, feeding habits are wide.
Loach is medium-to-high grade aquatic products, fine and tender taste, delicious flavour, nutritious, being rich in mineral element and a large amount of vitamin such as protein, fat, carbohydrate and calcium, phosphorus, iron, is deeply by the tradition delicious food that domestic and international consumer likes, the huge market demand.
At present, domestic only have " modern agriculture science and technology " periodical to report the test that Chalcalbumus chalcoides aralensis supported by Procambius clarkii cover, and " aquaculture " periodical reports the test that Chalcalbumus chalcoides aralensis supported by crab pond cover, does not also have Chalcalbumus chalcoides aralensis to overlap the report of supporting loach.The technology such as Chalcalbumus chalcoides aralensis stocking model, pond management are still immature, urgently improve the aquaculture model of Chalcalbumus chalcoides aralensis.
Summary of the invention
The object of the invention is to the aquaculture model improving existing Chalcalbumus chalcoides aralensis, provide the Chalcalbumus chalcoides aralensis cover of a kind of output and high efficiency to support the cultural method of loach.
Technical solution of the present invention:
A cultural method for loach supported by Chalcalbumus chalcoides aralensis cover, it is characterized in that: comprise the following steps:
1) choose, level, sterilize in pond: choose and have abundant water resources, enter that draining is convenient, around pollution-free source, water retention property is good, breeding facility is complete, area is 3 × 667 ㎡ ~ 5 × 667 ㎡ pond, and configuring aerator, discharge outlet is escaped on guard with anti-.Winter drains Chi Shui, with mud at the bottom of artificial or mechanical chipping pond, fully tan by the sun at the bottom of the rear smooth pool, heightening and consolidation pool base, repair Chi Po, Chi Geng, maintenance water channel, water channel, bait throwing in frame, remove pond surrounding foreign material, kill grass-seed and worm's ovum, put front 16d ~ 20d in a suitable place to breed, with 160 ㎏/667, ㎏ ~ 200 ㎡ quicklime band water sterilizations, the depth of water 15 about ㎝, then evenly turns over rake bed mud.It is dark that the rear 12d ~ 14d of sterilization adds water to 1.3m ~ 1.5m in pond;
2) fingerling stocking: mid or late March, selects that physique is healthy and strong, vigor is comparatively strong, anosis without wound 2 age Chalcalbumus chalcoides aralensis, mu puts 4000 tail ~ 5000 tails, the every tail 40g ~ 45g of specification, with 3% ~ 5% common salt aqueous solution dipping bath 5min ~ 10min before putting in a suitable place to breed.Mid-April, mu puts long 6 ㎝ mud fish fry 10000 tail ~ 12000, ㎝ ~ 8 tails of body, and mud fish fry puts front 3% ~ 5% common salt aqueous solution dipping bath 5min ~ 10min in a suitable place to breed;
3) feedstuff feeding: Chalcalbumus chalcoides aralensis is omnivorousness, temperate water fishes, eating carp crucian carp, loach feed, feed of throwing something and feeding is the special compound feed of loach that protein content reaches more than 32%, throw something and feed every day 2 times, daily ration of feeding accounts for 3% ~ 5% of fish body weight, July ~ August high temperature season daily ration of feeding to account for fish body weight be 8% ~ 10%, eat up as principle with 1h;
4) water quality management: keep water quality fertilizer to live tender refreshing, check ammonia nitrogen, content of nitrite in water body every 2d ~ 4d, keep transparency 25cm ~ 30cm, more than dissolved oxygen 5mg/L.Summer high temperature weather changes a water every 7d ~ 10d, and each quantity of exchanged water is water level 15 ㎝ ~ 20 ㎝.When high temperature season fine day to open aerator 1h ~ 4h, cloudy day noon m seq open aerator 1h ~ 3h, unbroken overcast and rainy time midnight open aerator 1h ~ 7h;
5) disease control: spring, autumn, is used alternatingly C5H6Br2N2O2, chlorine dioxide, bleaching powder carries out disinfection, use once every 28d ~ 32d.Summer high temperature uses EM bacterium, photosynthetic bacteria full pool spilling head season, uses once every 13d ~ 17d;
6) fish for: at the beginning of 11 months, when pond water temperature drops to about 15 DEG C with cage harvesting loach, late November draws in the net to catch Chalcalbumus chalcoides aralensis, and at the beginning of 12 months, dry pond is fished for.
Beneficial effect of the present invention:
Chalcalbumus chalcoides aralensis is epipelagic fish, and loach is demersal fishes, and the present invention adopts cover in Chalcalbumus chalcoides aralensis pond to support the breeding way of loach, not only do not affect Chalcalbumus chalcoides aralensis cultured output, specification and quality, and fully develop Water space, increase pond culture kind, improve water body environment.Compared with single cultivation Chalcalbumus chalcoides aralensis, output increased more than 30%, benefit improves more than 20%, adds the income of culturist.
