Abstract
The invention discloses a breeding method for increasing the survival rate of yellow catfish fry. The method includes the steps of pond selecting, bait breeding, water grass planting, fry putting, bait putting, water quality managing and daily managing. The breeding method is scientific and reasonable; by adopting methods of applying decomposed manure, increasing the oxygen content of a water body in a pond, replacing pond water in time, cleaning a food table, applying sterilize medicine and the like, the water quality is ensured and adjusted, the frequently-seen diseases of yellow catfish are effectively prevented, the immunity of yellow catfish weak in constitution at a fry stage is enhanced, the transition from endogenous nutritive yolk to exogenous nutrients can be well completed for fry, and the fry is balanced in nutrient, high in survival rate and rapid in growth speed and has good breeding and popularizing value.
Description
Technical field
The present invention relates to aquaculture field, be specifically related to a kind of cultural method improving fulvidraco larvae survival rate.
Background technology
Pelteobagrus fulvidraco is subordinate to Silurformes, Nian section in classification, and widely distributed in China, although its individuality is less, but its meat flavour is delicious, nutritious, the deep welcome by consumers in general. Based on market, the demand of Pelteobagrus fulvidraco is continued to increase, adopt mixed feed to carry out the intensive of Mylopharyngodon piceus in recent years and large-scale cultivation also gets more and more. Currently mainly culturing area is Foshan, Jiangmen, and Sichuan and Jiangsu and Zhejiang Provinces one are with. When fry is paid from egg membrane, begin at and grow outside egg membrane, enter alevin stage. Prelarva early stage relies primarily on yolk nutrition, starts to ingest when yolk sac absorbs after complete beginning, and this stage prelarva mortality rate is big, if even if enough agreeable to the taste bait can not be provided, the prelarva of this critical days will mortality. Additionally, intensive high density artificial breeding easily breaks out bacterial disease and parasitic disease, the deterioration of cultivation water environment also results in fish immunity power and declines, and has a strong impact on Pelteobagrus fulvidraco normal growth, thus causing the generation of disease, fulvidraco larvae growth is slow, survival rate is low.
Summary of the invention
For the deficiencies in the prior art, the invention provides the cultural method of a kind of Pelteobagrus fulvidraco, overcome that current artificial breeding's fulvidraco larvae survival rate is low, grow slow defect.
For realizing object above, the present invention is achieved by the following technical programs:
A kind of cultural method improving fulvidraco larvae survival rate, comprises the following steps:
1) pond select: selected depth be 2-2.2m, slope than for 1:2-3, area 1-2 mu pond as seed rearing pond, cleaning pond bottom mud and foreign material, smooth and some discharge outlet are set by repairing at the bottom of pond, be provided with silt at the bottom of pond, throw Seedling before 10 days with quick lime to pond disinfection;
2) cultivate bait: after sterilization of cleaning up the pond, throwing Seedling first 7 days, add, in pond, cattle and sheep muck cultivation water quality of becoming thoroughly decomposed according to the ratio of every mu of 60-70kg, and breed appropriate natural bait;
3) plantation pasture and water: in dispersion plantation pasture and water at the bottom of pond, and control its breeding amount, it is prevented that the excessive covering water surface;
4) fry is thrown and supports: ensure pond depth of water 1.5-1.8m, with aerator to, after pool oxygenation 10-15h, putting 10-12 ten thousand tail high-quality advanced fry of yellow catfish in a suitable place to breed for every mu;
5) bait feeding: 2-3 fixing food platform is set in pond, throw something and feed every day powdery compound feed 2-3 time, each feeding volume by the 3-6% of fish body weight, during 6-7 in morning, 2-3 at noon time, 7-8 in afternoon time respectively throw something and feed 1 time, and the mass ratio of bait of throwing something and feeding is 2:1:3;
6) water quality management: pond is noted weekly and filled out 1 10-15cm of new water, monthly changes water 1-2 time, and each quantity of exchanged water is the 40%-50% of Chi Shui, controls pond water pH value between 7.5～8.0;
7) daily management: use noon every day aerator to be pool oxygenation 2-3 hour, and every first quarter moon cleaning food platform, by germ killing drugs full pool spilling head or food platform hanging bag.
Preferably, described step 1) in pond bed mud sand thickness be 10-15cm.
Preferably, described step 1) quick lime makes consumption be every mu of 70-80kg.
Preferably, described step 2) in natural bait include Bellamya quadrata, wheel animalcule, naupiar larva, cladocera, Copepods bait etc.
Preferably, described step 6) kill Bactericidal medicine and be made up of the component of following weight portion: quick lime 30 parts, the Radix Astragali 12 parts, Cortex Magnoliae Officinalis 10 parts, Cortex Hibisci 15 parts, 12 parts of Bulbus Allii, Rhizoma Acori Graminei 8 parts, Radix Cucurbitae 12 parts, Folium Viticis Negundo 7 parts, Herba Taraxaci 10 parts, the Radix Angelicae Dahuricae 10 parts, Rhizoma Zingiberis 10 parts, Caulis Sargentodoxae 10 parts, Herba Dendrobii 10 parts, Radix Scutellariae 10 parts, Radix Arnebiae (Radix Lithospermi) 6 parts, Folium Artemisiae Argyi 10 parts, Herba Schizonepetae 8 parts.
Preferably, the preparation method of described germ killing drugs is as follows: a. weighs each component in proportion, pulverizes; B. add in Radix Astragali magnolia obovata 6 times of gross mass 60% ethanol, be heated to reflux 2h, filter, then add in filtering residue 3 times 60% ethanol, be heated to reflux 1h, filter, merge twice alcohol extract; C. by filtering residue and Cortex Hibisci, Bulbus Allii, Rhizoma Acori Graminei, Radix Cucurbitae, Folium Viticis Negundo, Herba Taraxaci, the Radix Angelicae Dahuricae, Rhizoma Zingiberis, Caulis Sargentodoxae, Herba Dendrobii, Radix Scutellariae, Radix Arnebiae (Radix Lithospermi), Folium Artemisiae Argyi, Herba Schizonepetae mixing, add the water of 6 times of initial gross mass, decoct 2h, filter, 4 times of water are added again in filtering residue, decoct 0.5h, filter, merge twice decoction liquor; D. alcohol extract, decoction liquor are merged, stir, be concentrated to extractum, dry; E. being joined by quick lime in dried extractum, 400 mesh sieves pulverized by pulverizer, obtained germ killing drugs.
The method have the benefit that cultural method of the present invention is scientific and reasonable, employing is used decomposed manure, improves pond waters oxygen content, changes Chi Shui in time, is cleaned food platform, the methods such as germ killing drugs of splashing, ensure and regulating water quality, effectively prevention Pelteobagrus fulvidraco common disease, make the immunostimulant of the more weak Pelteobagrus fulvidraco of juvenile stage body constitution, prelarva can be made well to complete by the transition of endogenous tropholecithus to exogenous nutrition, and nutritive equilibrium, larvae survival rate is high, fast growth, has and well cultivates promotional value.
