Abstract

The occurrence and prevalence of fish diseases bring heavy loss to culture production. The loss of fish death caused by the diseases can be prevented or decreased only by carefully doing fish disease preventing and controlling works well and actively carrying out the principles of early prevention of the diseases when no diseases appear, early treatment of the diseases when the diseases appear and prevention prior to control. The basic measurements for preventing and controlling the fish diseases are to scientifically feed, improve the environment of an aquaculture water body, eliminate the sources of an infectious disease, cut off transmission route and improve disease resistance of fishes.

Description

Throwing something and feeding and disease-preventing method of a kind of aqiuculrue

Technical field

This method relates to the breed field of aquatic products, is primarily aimed at traditional aquaculture model and is presented in the cultural method that breed feeds intake and prevents the fish disease aspect.

Background technology

Traditional aqiuculrue, Raising Fish in Net Box in Reservoir are not leveled for a long time because of the pond, do not have sterilization, the side of a pond is weedy, and the pond sludge corruption plants that matter is too much, and water quality degenerates, and a large amount of breedings of pathogene cause dead fish in the general pool and fish to raise the nose above water to breathe phenomenon easily.

Summary of the invention

(1) throws feed, fertilising major technique

Throwing feed, applying fertilizer is a ring in the aqiuculrue management, and it relates to water temperature, water colour, weather and fish dynamic dispatching factor, is a technical very strong job, can not ignore it.Therefore must grasp " four see ", " four is fixed "." four see ": " seeing water temperature ": when low, its food ration is few, needn't throw too much feed and fertilizer, and is higher in temperature, the water temperature of summer, Qiu Liangji in spring, water temperature in winter for fish, and that fish scoop up is heavy, growth is fast, and throwing the amount of raising will raise and increase gradually with water temperature; " see water colour " and want application in time when water colour is light; If will suspend fertilising when finding the water quality overrich, also can add new water; " see the colour of sky ": the fine steady visual appetite of weather is thrown more, overcast and rainy few the throwing, and weather is sultry, air pressure is low, should stop to throw behind the shower and raise; " see the dynamic of fish ": patrol the active situation that fish is observed on the pool early morning, see whether have fish floating head phenomenon and floating head degree thereof, determine to throw the same day amount of raising." four fixed ": " decide matter ": fresh, the cleaning of must throwing something and feeding, the fresh and tender feed of being assimilated by fish easily, refuse with the feed that goes bad; " quantitatively ": the feed injected volume of every day should accomplish evenly, can not the time few for a long time, increasing also should progressively increase when feeding intake, in order to avoid full phenomenon when hungry when causing fish; " regularly ": throw and raise secondary the general every day of feeding intake, promptly the morning and afternoon each once, the morning, afternoon, the fry and fingerling phase can throw something and feed once during 11-12 at midnight when 4-5 when 9-10; " location ": anchor point should be arranged on less affected pond or water inlet, sets up the food platform.

(2) fish disease prevention and cure

In the cultured fishes production process, pond regulation, medicine are cleaned up the pond except that carrying out conscientiously, the sterilization of fish body and the work of strengthening management, conscientiously carry out chemoprophylaxis, accomplish that anosis morning anti-, and the work that control ill morning can take following method to prevent.1, a food sterilization: hang three bags of bleaching powder at the food platform, every bag 150 gram, change once every day, hung continuously 3-4 days; Hang three bags of copper sulphate, ferrous sulfate hybrid medicine at the food platform, every bag of usefulness is 100 grams: 40 grams, change every day once, and hung continuously 3 days.2, pond water sterilization: with bleaching powder 1 gram/m3, full pool spilling head behind the dissolving water, 10 days are once, promptly come into effect from mid-April; With full pool spilling head behind the molten water of quicklime (15-20 kilogram/1 meter/mu), administration time began at the beginning of 4 months, and 10 days once.3, green fodder, organic manure sterilization: green fodder is put into per hundred kilograms of water bodys contains and soak the fish of throwing something and feeding after 5-10 minute in the 0.1-1 gram bleaching powder.4, the pharmaceutical chemistry of throwing something and feeding is prevented and treated the enteritis disease, and with sulphaguanidine 10 grams, garlic powder 250 gram/hundred kilograms of fish bodies (first day), medicine reduced by half in second to the 6th day, mixed concentrated feed and threw something and fed.5, implement Technique in Fishes injecting immune vaccine, consumption is with reference to the annotated consumption of vaccine bottle.6, Chinese herbal medicine immersion prevention with big tea medicine, a bitter leaf, eucalyptus leaves, pine tree hair, tobacco tree 250-350 jin, is tied into several respectively, throws into Chi Shuizhong and macerates and soak, treat that it rots after, continue input again and macerate water, reach prophylaxis effect.

Technique effect

According to said method in the management process that pond culture is produced, correct handle throw raise, the relation of fertilising and change of water quality, accomplish that the science throwing raises, applies fertilizer " even, good, sufficient ", can guarantee that the good water quality in pond payes attention to the control of fish disease simultaneously, can effectively reduce the incidence probability of tail as hemorrhage.

Specific embodiment

One, the feed of throwing something and feeding: based on the pellet of throwing something and feeding, manufactured feed uses raw material such as the dish dregs of rice, wheat bran etc.Adhere to " four see " principle: promptly see weather, see water temperature, see water quality, see ingesting and active situation of fish.

Two, fish disease prevention and cure:

1, due to the disease of control fish is fish body pathogene and three combined factors effects of living environment, should carry out " anti-overweighting controlled " and " prevention comprehensively ", the policy of active treatment is implemented integrated control.

2, select high-quality, the fingerling that body is strong is to strengthen resistance against diseases.Adhere to that four throw something and feed surely, prevent that the fish body is injured.

3, adopt chemoprophylaxis, eliminating pathogen is thoroughly cleaned up the pond as quicklime, sterilization, and the fingerling sterilization, the food field, the sterilization of food platform, fishing is sterilized with instrument, saturating medicine feed bait etc.

4, note ecological diseases prevention, keep water quality good, prevention water quality deterioration and low dissolved oxygen syndrome are improved the living environment of fish, implement the regulating and controlling water quality complex art, the general pool of prevention floating head phenomenon.

Claims

1. throwing feed, applying fertilizer is a ring in the aqiuculrue management, and it relates to water temperature, water colour, weather and fish dynamic dispatching factor, is a technical very strong job, can not ignore it.Therefore must grasp " four see ", " four is fixed ".
