【正文】 o raise fish, failed to do it after the winter fishing dry pond, available drainage machine will pond pond dam on bunds of weeds, to reduce the insects such as spawning sites. At the same time strengthening pond base, to prevent leakage. ?。?）藥劑清塘，殺毒消菌。有些魚類池塘，若清塘清池前無法排水，或原池水排出后又無法補(bǔ)人新水，可以進(jìn)行帶水清塘。t fill one new water, can carry out with clear water pond. 3凈化水質(zhì)。該原理是：“在某個(gè)單元中，某一物質(zhì)的累積量，等于該物質(zhì)的進(jìn)流量減去出流量，再加上增生量。光合細(xì)菌投入池塘中，能迅速消除水體中的氨氮、硫化氫、有機(jī)酸等有機(jī)物質(zhì)，平衡酸堿度，改善池水質(zhì)量。(1) photosynthetic bacteria to purify water quality. Photosynthetic bacteria into the pond, can quickly eliminate water in organic materials such as ammonia, hydrogen sulfide, organic acid, balance the ph value, improve the water quality. On the photosynthetic bacteria will note: multistrain mixture is better than single bacteria feeding。 Can be share with medical stone, zeolite etc, the effect is better。t share with disinfectant, so as not to be killed. ?。?）凈水活菌凈化水質(zhì)。不僅能凈化水質(zhì)，還為單胞藻的繁殖提供了大量營養(yǎng)。(2) to purify the water to water purification. Water purification of live bacteria can is by a variety of different bacteria, improve the function of water quality, they overcame the photosynthetic bacteria can not directly using the macromolecular organic matter, does not depose biological bodies and remnant feces, both oxidation, ammonification, nitrification, denitrification, phosphatesolubilizing, vulcanization, and the function of nitrogen fixation. Not only can purify water quality, but also for single cell algae breeding provides a lot of nutrition. And fish meat is delicious, the market price is high. 二、節(jié)省飼料費(fèi)用。1以青代精，利用塘埂、荒地種植牧草、利用溝渠等水域養(yǎng)殖浮萍，或采集嫩草雜草來喂魚，可以節(jié)省精料。實(shí)踐證明以菜粕、血粉等為主要原料，添加適量油脂、維生素、礦物質(zhì)配成的餌料，營養(yǎng)物質(zhì)能達(dá)到魚類的需求量，養(yǎng)魚效益較好。維生素C可阻止有毒物質(zhì)在魚體內(nèi)殘留，具有解除法操作簡便．快速．準(zhǔn)確靈敏清除毒性物質(zhì)的功能。腐殖酸是養(yǎng)殖動(dòng)物綠色飼料添加劑。4．消除藥物殘留?？墒褂脤χ虏【袑Ｒ恍缘耐撩顾亍⒒前粪奏?、新諾明、氟苯尼考等環(huán)?？股亍Ｋ幬餁埩粝?，可增加口感，產(chǎn)品的價(jià)格自然會(huì)提升。 fisheries research institute (1995) with appropriate concentration of humic acid aqueous solution feeding prawn pond, rippled results humic acid could effectively prevent the heavy metals such as copper, lead, nickel to the harm of fish growth and reproduction, promote fish grow faster. 4. Eliminate the drug residues. Of pollutionfree food fish by the national ministry of agriculture issued and implemented with drug use code provisions, sulfaguanidine, is strictly prohibited nitrofurazone, furazolidone, chloramphenicol, erythromycin, ciprofloxacin, sand magnitude of antibiotics
