Abstract

The method of sterilizing fish pond in spring includes spreading water with 75-100 kg of lime and 50 kg of camellia bran soaked for one night in each mou of 1 m deep water, sterilizing fish body through soaking in 4 % concentration salt solution for 10-15 min before setting in pond, shelving feeding stage with bamboo pole and hanging bamboo baskets holding bleaching powder in 3-5 g each, spraying bleaching powder with 30 % chlorine content in 1 kg twice a month, spraying water with lime in 20 kg once every 20 days, spraying water solution of dipterex in 0.2 kg, and spraying copper sulfate and ferrous sulfate mixture once a month.

Description

A kind of spring the fish pond sterilization method

Technical field

The present invention relates to the sterilization method in fish pond in a kind of spring.

Background technology

The pond is the place that aquiculture animal is perched, and also is the place that pathogene is grown.Whether pond environment cleans, and directly has influence on the health of various aquiculture animals such as fishes and shrimps.Sterilization is the indispensable important ring of aquaculture work so clean up the pond, and must pay much attention to.In spring, the pond water temperature is gone up gradually, and it is gradually prosperous that fish open food back appetite, captures the year-round fishery good harvest, and the management work in spring is crucial.The beginning of spring, temperature went up gradually, and all kinds of fish ponds all begin to prepare to breed fish fry breed, and various biological self reproducings are accelerated in the fish pond, and various metabolites are on the increase, and the germ parasite of harm fish will enliven gradually.For this reason, should carry out the disinfection in fish pond in spring.

Summary of the invention

The present invention relates to the sterilization method in fish pond in a kind of spring, reach the purpose of the sterilization of cleaning up the pond by following four sterilisation steps: (1) sterilization of cleaning up the pond: every mu of one meter dark water surface is freeed lime 75-100 kilogram, after the camellia bran is smashed the night of soaking for 50 kilograms evenly splash in the full pool, the tea bran of splashing again behind the lime of splashing earlier was separated by 3-5 hour.(2) fingerling sterilization: the fingerling seedling falls before the pool and to carry out slowly being put into the fish pond breed again after the fish body surface sterilized 10-15 minute with 4% salt solution.(3) a food sterilization: the pond of breeding fish, be barricaded as triangle or tetragonal food stand with bamboo pole, each food field only hangs 3-6, and dress bleaching powder 3-5 gram hangs over and eats around the stand in every bamboo basket, and bamboo basket surfaces slightly.(4) fish pond pasteurised completely:, evenly splash with 1 kilogram of full pool of bleaching powder of chlorinty 30%, semimonthly by the water surface of 1 meter of every mu of depth of water; The water surface that every mu of depth of water is 1 meter is changed the full pond of water with 20 kilograms of quicklimes and is evenly splashed, and per 20 days once; The water surface that every mu of depth of water is 1 meter is changed the water-soluble full pool spilling head of separating for 0.2 kilogram with 90% crystal chlorophos; Every month with copper sulphate and mixture of ferrous sulfate (5: 2) full pool spilling head.

Specific implementation method

1. cleaning up the pond, the fish pond is newly dug in sterilization, the old man transforms desilting and will carry out the disinfection of cleaning up the pond.General every mu of one meter dark water surface is freeed lime 75-100 kilogram, and after the camellia bran is smashed the night of soaking for 50 kilograms evenly splash in the full pool, and the tea bran of splashing again behind the lime of splashing earlier was separated by 3-5 hour.Quicklime can kill wild fishes, virus, bacterium and parasite, and neutralization is acid, discharges nutrient, and improvement substrate and water quality make water body become alkalescence; And the tea bran is separated the glucoside toxin because of containing soap, the same can kill wild fishes and some germ parasite, cultivates water quality, and after the toxicity, the tea bran also is that the fingerling seedling is liked the bait of ingesting.And water disinfection was also wanted in the fish pond of surviving the winter in 1-2 days before putting kind, and the water surface that every mu of depth of water is 1 meter carries out the water disinfection sterilization with 1 kilogram in bleaching powder, and then put the pool breed that falls of fingerling seedling.

2. the fingerling careful operation of sterilizing is in any case drawn in the net, and can abrade the fish body surface scale and the gill cover unavoidably, bacterial infection and parasite because of intensive frightened the beating of fish when catching the fingerling seedling.Need salt solution to carry out the sterilization of fish body surface after 10-15 minute before the pool so the fingerling seedling falls, slowly be put into the fish pond again and culture, to reduce death rate of the onset in the future with 4%.

3. a food sterilization food sterilization is very important, can save aquaculture cost, and the particularly big water surface is cultured, and just seems particularly necessary.The pond of breeding fish is barricaded as triangle or tetragonal food stand with bamboo pole, and each food extension 3-6 only, dress bleaching powder 3-5 gram (the packed bleaching powder of available plastic cement in every bamboo basket, puncturing several apertures with needle point passes in and out by water), hang over around the food stand, bamboo basket surfaces slightly.After bamboo basket hangs up properly, feed is placed in the food stand, connects at every turn and hung 3-5 days, change dressings once every day.

4. fish pond pasteurised completely

4.1 by the water surface of 1 meter of every mu of depth of water, evenly splash, can prevent the bacterial diseases of fishes, semimonthly with 1 kilogram of full pool of bleaching powder of chlorinty 30%.

4.2 the water surface that every mu of depth of water is 1 meter is changed the full pond of water with 20 kilograms of quicklimes and evenly splashed, and can prevent fin rot, per 20 days once.

4.3 the water surface that every mu of depth of water is 1 meter is changed the water-soluble full pool spilling head of separating for 0.2 kilogram with 90% crystal chlorophos, can kill Chinese fish flea, the larva of anchor head lice.

4.4 every month with copper sulphate and mixture of ferrous sulfate (5: 2) full pool spilling head, can kill parasite and cross because of water body and abound with living blue green algae.The medicine sterilization is sprinkled in the fishpond will look weather, water temperature, the arrangement of shoal of fish active situation.Weather is normal, and water temperature is normal, the liquid medicine of splashing during the no abnormal 3-4 in the afternoon of the shoal of fish; If rain in torrents, air pressure is low, and water temperature is low excessively, anoxic is raised the nose above water to breathe and the shoal of fish have unusually then can not medication, otherwise can worsen water body environment and increase the weight of the fish state of an illness, cause economic loss.
