A, frequently observed, early treatment <> br/fish are pathogen infection or general invasion, have a process, there are some signs, such as disease activity slow, often slow fish swim in the water's surface, no cluster, if have moved, slightly atrophied after, namely surface. Also have some fish just onset, crazy swim nasty channeling, or body color gloomy, flake off, etc. Be like again, white hybridaze bleeding after the occurrence of the wild, early fishponds small miscellaneous fish death, etc. When you discover that appear in fish disease symptom pond when, should take timely measures, treatment, can avoid illness expansion. Br/> <<> 2, br/accurate diagnosis, suit the remedy to the case "br/> first according to climate characteristics, fish and water sources, any proportion and density raising management calendar year, fish disease prevalent regularity, fishes appetite, action, and the body color, etc, a field survey on analysis. Then will the impending death, disease fish or death without corruption become, on the surface, YuShi gill filament, muscle, viscera in areas such as the bra checks or microscopy. See its surface have appeared large parasites 鳋, anchor head of 鳋 etc, or bleeder block, flake off, rotten anal fin, red wait for a phenomenon. Gills department, gills cover hyperemia corrosion, gill filaments color, mucous how much, parasite, gill filaments rot with mud. After dividing of open the stomach, whether to have ascites, intestinal irritation, congestion, liver and spleen organs such as the hyperemia. Unwrap a fishskin, muscle is bleeding. According to the specific symptoms, check first diagnosed parasites, bacterial, viral disease or complications, and then based on the comprehensive disease fish performance analysis, make accurate diagnosis, suit the remedy to the case. Br/> <<> br/three, accurate measurements, with accurate dose <> br/gauge precisely, with accurate dose treatment is fish disease effect is good or not another key. Foreign medicine, the whole pool splatting, accurate predictions pool water volume, and you should consider to water characteristics and then water heat effects, such as organic matter more, the water quality is fat, water temperature is lower, dosage should be more. Pool water volume to measure the actual water and average depth calculated. The average depth of measurements, taking the pond several two-tone depth of average shall prevail. Orally drug doses to every kilograms of fish body ingestion to how many drugs to say, specific often two calculation methods: according to the weight computation and press feeding rate computation, should be applyinged neatly. When the pond most fish feeding exuberant, according to the total weight of the pond fish calculation is more accurate, When ChiYu serious condition or climate is bad, cause anorexia, should according to estimation of feeding rate, by higher proportion will drug stir in baits, to ensure that the disease is still can feed fish to eat enough dose. Preparation YaoEr, also should consider to drugs in the water loss. Note estimate the total weight pond fish, want to consider each stage growth increase weight ratio, cannot be launched YaoEr species of feed the amount of calculation. Br/> <<> br/drug characteristics, four, mastery of scientific and medical treatment
pets question and answers,www.5d2d.com fish disease commonly used medicines each has its physical and chemical characteristics, in the preservation use should be paid attention to when rationalization, avoid drugs for save caused by misuse failure. If what drugs is for external use only, what drugs orally effect is good, what drugs cannot share. What medicines to get better effect, which drugs can by environmental factor influence, etc. YaoEr should consider a fish living habits, making buoyancy, countersunk sex, particles, different YaoEr. General be like green, pathogenesis, crucian carp cyprinus should feed the sink sex YaoEr; Grass carp onset to feed the flotability of YaoEr or mix medicine in grasses on better; BaiLian onset should feed particles YaoEr, when making to stir in a certain amount of adhesives, in case of drugs in the water loss. Drug splatting will drug dissolves evenly splatting whole pool, in the afternoon time splatting is better, because of high temperature, high efficacy in the afternoon. Splatting drugs from windward gradually to lee side splatting, splatting left after the slag residual grain dissolved drugs, cannot spilled into the pool. Otherwise fish swallow will cause poisoning death. Br/> <<> br/five, according to the disease categories, with enough treatment <> br/cure period of treatment is the fundamental guarantee of fish disease, not enough treatment, cannot completely destroy pathogens, not a drug effect. Therefore, with the full period of treatment is completely destroy pathogens, consolidate curative effect important segment. Practice course of length, should according to fish of disease specific category. Such as aggressie disease is caused by the parasite, generally use insecticides content 1 ~ 2 days for a period of treatment, can have the objective of treatment, Such as bacterial, viral disease generally 3 ~ 5 days for a period of treatment. As for use of treatment, how much will be changed according to the illness weight and progression priorities and decide. The prognosis heavy, duration long disease is necessary to use two to three treatment, otherwise curative effect is not complete, have heavy hair infection may. Br/>
