Abstract
The invention discloses a pollution-free healthy culture method of grouper in a pond, which comprises the following steps: (1) pond preparation: selecting sand substrates or silt substrates as pond substrates, firstly insolating and dredging, then pouring the substrates into deep sea water, applying quick lime per mu for sterilizing and improving the substrates, and discharging the quick lime after 24h; (2) working before seeding: after the pond is prepared well, pouring water, sterilizing the whole pond with chlorine dioxide, and applying special fertilizer for aquiculture and beneficial microbial agents containing bacillus after 24h; (3) seedling stocking: stocking seedlings according to the density of 700-1300 per mu; (4) bait feeding: feeding fresh sea water trash fish cream at the early stage of culture of seedlings, and feeding soft granulated feed or special commercial feed for grouper at the middle and later stages of culture of seedlings; and (5) water quality management: controlling the transparency and the pH value of pond water, and regularly applying beneficial microbes once into the pond. The culture method of grouper of the invention controls the water quality by applying beneficial microbes and organic fertilizer, reduces the use of medicines and improves the value of products.
Description
Technical field
The present invention relates to a kind of aquaculture method, especially a kind of pollution-free healthy culture method of grouper in pond.
Background technology
Epinephelus is in from Perciformes, Epinephelus, and, delicious meat nutritious because of it are welcome by domestic and international consumer deeply in recent years.At present, propagating artificially of grouper all actively developed in coastal various places.Yet, traditional cultural method cost height, pollute big, yield poorly, poor quality, as shallow sea cage culture, a large amount of net cages of need purchasing are equipped with numerous personnel's nurses, are subject to the natural calamity influence, grouper often has escape, coastal waters water quality inferiority disease is many, and dispenser, drainage, residual bait further aggravate the cage culture environmental deterioration, so that grouper is cultured low, of poor quality, the edible safe and sanitary hidden danger that exists of efficient; Although the aquaculture model of some closure intensifications quietly rises, broken away from the constraint of natural environment, because problems such as cultural technique is lack of standardization, abuse of antibiotics are still outstanding, grouper aquaculture industry contaminated environment, the low inferior problem of product quality are not effectively solved.
Summary of the invention
The technical problem to be solved in the present invention provides the pollution-free healthy culture method of grouper in pond that a kind of cost is low, pollution is little, output is high, product are of fine quality.
For solving the problems of the technologies described above, technical scheme of the present invention may further comprise the steps:
(1) prepare in the pond: bottom material of pond for breeding is sandy or husky shale, earlier through tanning by the sun, desilting, include 20～30cm deep-sea water then in, 30～70 kilograms of every mu of applying quick lime carry out disinfection and improve substrate, drain behind the 24h;
(2) put the preceding work of seedling: water inlet 100～120cm was dark after the pond was ready to, carry out the sterilization of full pond with chlorine dioxide, making its concentration is 0.5～1.0mg/L, dispensing aquaculture special-purpose fertilizer 2～4mg/l and the effective microorganism preparation 1～2mg/L that contains bacillus 2,000,000,000/gram behind the 24h;
(3) seed is put in a suitable place to breed: the density by 700～1300 tail/mus is put seed in a suitable place to breed;
(4) bait feeding: seed is cultivated in earlier stage, the seawater small fish slurry of throwing something and feeding fresh, and the seed middle and later periods cultivates, the special-purpose commercial feed of throw something and feed soft pellet diet or grouper;
(5) water quality management: 7.8～8.5, per 15～20 days to pond dispensing beneficial microbe once in 40～60cm, pH value for the control water transparence.
5～8 mu of pond areas, dark 1.5～2 meters are laid stone riprap or are thrown in punctured tire, watt water drum at the bottom of the pond.
Before putting in a suitable place to breed, seed use the poly-dimension iodine aqueous solution of available iodine concentration 0.3～0.7mg/L to soak 3～5min earlier.
Seed is individual neat, the long 12～15cm of body.
Seed is put in a suitable place to breed and also comprises black porgy 20～70 tail/mus, grey mullet 70～130 tail/mus of raising together with same specification.
During seed was cultivated in earlier stage, feed coefficient was 1: 5～1: 11, and daily ration of feeding is 8%～12% of a fry body weight, and in the cultivation of seed middle and later periods, feed coefficient is 1: 0.8～1: 1.6, and daily ration of feeding is 2%～5% of a seed body weight.
Add the elver feed in the fish slurry and regularly add the marine fish multidimensional.
Water quality management also is included in to culture and added 3～8cm seawater per 3～5 days of early stage, and up to the pond depth of water 1.5～2.0m, per 3～5 days of middle and later periods was discharged bottom sewage, replenished fresh seawater simultaneously, and quantity of exchanged water is 5～10%.
Chi Shui handles through circulation.
Because current prawn culturing disease is many, the cost height, shrimp valency depression, the breed enthusiasm of shrimp farming is not high, causes the idle of a large amount of ponds.The present invention has made full use of the idle resources of production, need not to buy in addition professional equipment, it is little that pond environment is influenced by natural calamity, industrialization administrative staff efficient improves, the cultural technique standard criterion, dispensing beneficial microbe and fertilizer are controlled water quality, reduce the use of medicine, make grouper reach non-harmful health requirements, promoted value of the product.But more than 700 kilograms, the grouper of conventional art was cultured annual production raising 25% on year-on-year basis by 2 years breed per mu yield groupers, and unit price improves 33%, and economic benefit improves 70%.
