Abstract

The invention relates to a pond artificial domesticating method for Acrossocheilus yunnanensis and belongs to the technical field of fish culturing. The method comprises the following steps of selecting and preparing a domesticating pond, i.e. selecting a rectangular cement pond as the domesticating pond, planting hornworts in the pond, wherein the area of the hornworts accounts for one third that of the whole pond, and simulating the natural environment; filling wild fish fingerling into the pond, feeding and domesticating the wild fish fingerling, and performing daily management on the wild fish fingerling, i.e. filling a complete formula feed with a particle size of 1.5mm and a protein percentage of 35 percent, wherein the daily feed filling amount accounts for 2 to 3 percent of the weight of the fishes, enabling water in the domesticating pond to slowly flow, exchanging the water body every 3 to 4 days, and filling 2 to 3g of allicin or Vc (vitamin c) for fish every one kilometer of feed every 20 days for 2 to 3 days continuously; preventing and controlling fish diseases, i.e. spraying povidone iodine and ethylene double ammonium dithiocarbamate into the pond to control every 15 days to prevent and control bacteriosis and balantidiasis, wherein the prevention dosage is 50 to 60ml per 0.0667 hectares, and the controlling dosage is 80 to 100ml per 0.0667 hectares. The survival rate and the growing speed of the wild Acrossocheilus yunnanensis can be effectively improved by the method, and the method is simple, and is convenient to use and popularize.

Description

The pond artificial domestication method of Acrossocheilus yunnanensis

Technical field:

The present invention relates to a kind of pond artificial domestication method of Acrossocheilus yunnanensis, belong to the fish culture technical field.

Background technology:

Acrossocheilus yunnanensis (Acrossocheilus yunnanensis) belongs to Cypriniformes, Cyprinidae, and Barbinae, light lip fish belongs to.The middle-size and small-size fish with the important ecological value and certain economic worth.Be distributed in Pearl River system, ChangJiang River upstream and tributary ，Wei China Endemic fish thereof, type locality, in Yunnan, has the plateau of adaptation cold water environment, and individuality is the characteristics of large (common individuality reaches 20～30cm).Due to reasons such as hydraulic engineering construction and river pollution, overfishings, Acrossocheilus yunnanensis germ plasm resource amount sharply reduces in recent years, and trace has been difficult to find on many ground, Yunnan, and recovering Acrossocheilus yunnanensis germ plasm resource has become the important research contents of Yunnan Province's fishery.Utilize this Species of Rare Fish from Qingdao resource in order to protect, from 2010, unit of the present invention adhered to collecting the Acrossocheilus yunnanensis wild germplasm, and carried out aspect researchs such as raising and train cultivation, artificial propagation and seed rearing.

The present invention is intended to carry out the pond artificial domestication research of wild Acrossocheilus yunnanensis.Through document retrieval, do not find at home the report identical with the present invention.

Summary of the invention:

The object of the present invention is to provide a kind of pond artificial domestication method of Acrossocheilus yunnanensis, that is:, by wild Acrossocheilus yunnanensis is invested in to man-made pond(pool), cultivate through the domestication, thereby reach to adapt to, propagate environment artificially, realize the normal growth growth.

The pond artificial domestication method of Acrossocheilus yunnanensis of the present invention, its concrete steps are as follows:

A. raise and train choosing and preparing of pond

Choose rectangle cement flowing water pond and clean and use the sterilization of splashing of the potassium permanganate of concentration 200ppm as raising and train ，Quan pond, pond, Yan Chang limit, upper and lower two ends, pond pool wall arranges 4 of food platforms with asbestos shingle and hollow brick, height 0.6m; Pond sterilization airing were injected source of clean water after 3 days, and dark 0.5m implants the hornwort pasture and water in the middle and upper part, pond, account for full pool area 1/3, then Chi Shui is filled it up with to 1.2m to simulating natural environment;

B. the input of the wild fingerling of Acrossocheilus yunnanensis

Before throwing in pond, the wild fingerling of the Acrossocheilus yunnanensis of long 8～15cm first carries out the sterilization of fish body, adopt potassium permanganate dipping 5～8min that mass percent is 1.5%～2% salt or concentration 100ppm, disinfecting container adopts Box of foamed plastics, cover lid and inflate oxygenation with air pump during sterilization;

C. ingest and tame and daily management

Throw in the wild fingerling of Acrossocheilus yunnanensis after 2～3 days, at the food platform surrounding artificial complete compound granular feed that albumen quality percentage is 35% of throwing something and feeding on a small quantity, particle diameter 1.5mm, dosage induces Acrossocheilus yunnanensis to ingest day by day; Form the artificial feed custom of ingesting after 10 days, adhere to that 10:00 every day, 16:00 respectively throw something and feed once, a day feeding volume accounts for fish body weight 2～3%; Raise and train pond and carry out miniflow water, water body exchange in 3～4 days once, keeps water cleaning bright;

D. fish disease prevention and cure

Within every 20 days, mix and raise throw something and feed allicin and Vc5 for fish～6 meal, every kilogram of feed is mixed medicine feed thing 2～3g, prevention of intestinal tract disease and building up resistance;

The prevention bacterial infection: preventive dose is every 15 days full pool spilling head povidone iodine 50ml/ mu, and therapeutic dose is 80ml/ mu, after dispenser, stops into water 10～12h;

The prevention balantidiasis: every 15 days full pool spilling head medicine ethylene bisdithiocarbamic ammonium 50～60ml/ mu, therapeutic dose 80～100ml/ mu, stop after dispenser into water 10～12h.

The pond artificial domestication method of Acrossocheilus yunnanensis of the present invention, have survival rate and growth rate that the wild fingerling of effective raising Acrossocheilus yunnanensis is raised and train, and method is easy, is beneficial to the advantage of applying.

Embodiment:

Raise and train in the invention process and use feed, disease control medication to be the market purchase.

The inventor adopts the inventive method to carry out the domesticating and cultivating research of Acrossocheilus yunnanensis pond in aquatic products technical advice station, Yunnan Province subordinate's cold water fish culture experiment base year March in March, 2010 to 2011, realize domesticating and cultivating Acrossocheilus yunnanensis 2100 tails.Raise and train survival rate and reach 83.1%, domesticating and cultivating anniversary afterbody length rises to 15～18cm by 8～12cm.Average weight increases to 80～150g by 10～30g, increases weight 5～8 times.Embodiment is as follows:

A. raise and train choosing and preparing of pond
