Abstract

The invention discloses a loach fry breeding method which includes the steps: sunning a V-shaped breeding pond until cracks and white coverings are formed at the bottom of the V-shaped breeding pond, and then injecting non-pollution water into the V-shaped breeding pond; placing chlorella into the pond to cultivate the water two days before feeding water spots into the pond, and adding the chlorella into the breeding pond every three days; adding tubificidae into the breeding pond after 7 days, performing pest control by fish insecticides with traditional Chinese medicine materials within 7-9 days; stopping use of the chlorella and mainly using the tubificidae and fish mash feed with 32 proteins after 14-16 days; stopping use of the tubificidae and completely using the feed for breeding after 22-24 days. The dosage of the fish insecticides is 0.4 gram per cubic meter of water, the usage amount of the feed is 80 grams per 10,000 loach fries every day, and finished inched fries are obtained after 28-30 days. The loach fry breeding method has the advantage that the survival rate of loach fry production is high.

Description

A kind of loach seedling-cultivating method
Technical field
The invention belongs to aquatic products technical field, relate in particular to a kind of loach seedling-cultivating method.
 
Background technology
Tradition loach seedling pond adopts flat design, and loach seedling needs the different depth of water at different sunlight and different weathers, and the flat manual adjustment depth of water of leaning on, wastes water, and labour intensity is large, also not accurate; Opening material adopts egg yolk, milk and rich water method, and we study and find that egg yolk and milk makes opening material loach seedling and can not digest, and what rich water adopted is nursery pond under fertilizer, in training water process, can produce poisonous and harmful substance; Loach seedling is to high light very responsive (nursery stage survival rate on rainy day is high, becomes a fine day survival rate low).Thereby traditional loach shoot survival percent is less than 10%, China Patent Publication No. CN101331858A, on December 31st, 2008, disclosing " a kind of loach seedling cultivation technology " mainly there is following problem in it:
(1) pond design, grow seedlings in the flat pond of routine of employing, cause seedling in production process by the output that is preordained, reason is the loach seedling morning, noon and afternoon all to need the different depth of water, otherwise there will be emergency reaction.
(2) use of base manure, manure use is applied in the production of loach seedling as base manure be a wrong way, because fertilizer is also producing harmful substance when producing microorganism in water body, can cause dissolved oxygen in water to reduce, pH value raises, this will bring loach spray seedling not opening eat.
(3) soya-bean milk opening, in the production of fresh water young fish, former traditional fry opening is all with soya-bean milk, it not is that fry eats soya-bean milk that research is afterwards found, but the protein of soya-bean milk can produce algae and microorganism in rich water process in water body, but there is individual problem, under soya-bean milk, behind pond, algae and production by biological have yeast phase of 48-60 hour in the middle of this before death, the dissolved oxygen amount of this yeast phase water body lower than 1-1.5 milligram rise below, pH value can surpass 9.2, and this is also to cause under loach spray seedling all the time behind pond one of reason that 3 days lethality are high.(4) having ignored direct sunlight affects loach seedling, loach belongs to demersal fishes, generally inhabits in pasture and water and mud under natural environment, and strong sunlight is larger on its impact, can cause the discomfort of environment to cause emergency reaction, this is also one of major reason of bubble illness formation.
 
Summary of the invention
A kind of loach seedling that the object of the invention is to overcome above-mentioned shortcoming and provide is produced into the loach seedling-cultivating method that motility rate is high.
A kind of loach seedling-cultivating method of the present invention, comprises the following steps:
(1) cultivation pond is wide 6 meters, and length is no more than 40 meters, and pond center bottom is dark 0.2 meter of 1 meter of limit deeply, has so just formed V-arrangement and has cultivated pond, and shine in pond breach and white skin to bottom, then put into the pollution-free water that 100 order net filtrations are crossed;
(2) under spray, training water in the pool under chlorella is used in first 2 days ponds, the pool, and the consumption of chlorella is that every cube of water is used 0.5 gram of chlorella; Under spray, fine day and open water spray while having mist (while having mist air pressure low can anoxic) after the pool, cultivates pond in every 3 days and adds chlorella one time, and consumption is the same; Within 7 days, cultivate pond later and add water earthworm, the consumption of water earthworm is that to make 0.5 jin of water earthworm, water earthworm Feeding time every day be 6-8 point every afternoon to every ten thousand tail loach seedlings; Within 7-9 days, use Chinese traditional medicine matter enemy worm for fishing to carry out a pest control, enemy worm for fishing consumption is 0.4 gram, every cube of water;
(3) within 14-16 days, stop the use of chlorella later, after 14-16 days, take water earthworm as main, consumption is the same, feed is auxiliary, and feed adopts the fish mash feed of 32 albumen, and feed consumption is that every ten thousand tail loach seedlings are thrown something and fed 50 grams every day, within 22-24 days, stop the use of water earthworm later, all adopting feed cultivation, is at this moment that feed usage amount is that every ten thousand tail loach seedlings are thrown something and fed 80 grams every day, and a cun seedling gets product for 28-30 days later.
The present invention compared with prior art, has obvious beneficial effect, as can be known from the above technical solutions: the V font design of nursery pond of the present invention bottom can allow loach seedling select voluntarily Qixia in its needed degree of depth; Water spray when cultivating the pond water surface at fine day and having mist (the low meeting of air pressure anoxic while having mist), has solved traditional growing seedlings and has determined the problem of loach shoot survival percent and solve high light and the impact of anoxic on loach seedling by weather; Starter diet is that chlorella is to eat the better food that can digest the spray opening stage, directly cultivates pond and uses the chlorella of purifying also not destroy water quality; Adopt the problem that the V font design of bottom, pond, water surface water spray, chlorella opening, Chinese medicine material enemy worm for fishing desinsection etc. have solved bubble illness comprehensively of cultivating.Loach seedling survival rate is more than 50%, far away higher than conventional method.
The specific embodiment of the present invention is provided in detail by following examples.
