【正文】 Pay attention to keep the water clean, the enhancement of the fish body resistance. In addition with rhubarb, Chinese gall, garlic, purslane, etc. Chinese medicine is effective for prevention and treatment of fish diseases. 總之，水產(chǎn)養(yǎng)殖是一項(xiàng)復(fù)雜且系統(tǒng)的工程，它涉及到多方面的問題，因此只有加強(qiáng)理論指導(dǎo)和技術(shù)創(chuàng)新，才能實(shí)現(xiàn)水產(chǎn)養(yǎng)殖的經(jīng)濟(jì)效益和社會(huì)效益。 Species range strictly sterilized before。In recent years, explosive fish disease to a great extent, restricts the development of fishery production. Some fish at ordinary times didn39。魚池應(yīng)徹底用藥物清塘；魚種放養(yǎng)前嚴(yán)格消毒；魚發(fā)病季節(jié)定期用藥物預(yù)防；注意保持水質(zhì)的清潔，增強(qiáng)魚體的抵抗力。綜合分析魚病的發(fā)生原因，采取相應(yīng)的對(duì)策，實(shí)行魚病綜合防治是提高養(yǎng)殖效益的必要措施。Four, strengthening prevention and control of fish diseases. 近年來暴發(fā)性魚病在很大程度上制約著漁業(yè)生產(chǎn)的發(fā)展。如有的養(yǎng)殖戶同一口池塘上半年養(yǎng)南美白對(duì)蝦，下半年養(yǎng)鯉魚，既提高了經(jīng)濟(jì)效益，又減少了病害的發(fā)生，效果好，值得借鑒。（2）是各種魚、蝦等輪養(yǎng)。也可多次放養(yǎng)大規(guī)格魚種，捕大補(bǔ)小。Third, adjust the density of livestock. 實(shí)行輪捕輪放和輪養(yǎng) （1）是魚類實(shí)行輪捕輪放，改變過去年底一次干塘起捕的習(xí)性，常年根據(jù)市場(chǎng)魚價(jià)適時(shí)起水銷售，賣個(gè)好價(jià)。Feed costs accounted for about 60% of the fish cost of above monly, wide monarch feed source, reduce feed costs, save money is the key to improving economic efficiency of fish farming. 1 to take advantage of youth generation, planting grass pond, bunds wasteland, use duckweed, ditches, such as water or collect the tender grass weeds to feed the fish, can save the concentrate. Summer can install in the fish pond 20 centimeters from the surface of the water 60watt bulb trap into the pool, and vigorously promote using cheap bread and bran etc, replace or less with the high price of fish meal, soybean meal and other ingredients, which can greatly reduce the feed cost. Practice proved in rapeseed meal, blood meal, etc as main raw materials, adding suitable amount of grease, match into the bait of vitamins, minerals, nutrients can reach the demand for fish, fish farming efficiency is better. 2 bait in the appropriate increase the vitamin C content. Vitamin C can prevent toxic residues in fish body lifting method is simple. Rapid. Accurate function sensitive to remove toxic substances. 3 add humic acid. Humic acid is farmed animals green feed additives. Chinese academy of agricultural sciences39。捕撈出售前一個(gè)星期．應(yīng)停止使用藥物性飼料添加劑，可減少藥物在魚體內(nèi)殘留。按國(guó)家農(nóng)業(yè)部頒布實(shí)施的《無公害食品漁用藥物使用準(zhǔn)則》的規(guī)定執(zhí)行，嚴(yán)禁使用磺胺脒、呋喃西林、痢特靈、氯霉素、紅霉素、環(huán)丙沙星等抗生素作餌料添加劑或水體防病劑。中國(guó)農(nóng)科院水產(chǎn)研究所(1995)用適當(dāng)濃度腐殖酸水溶液潑撒飼養(yǎng)對(duì)蝦水池，結(jié)果腐殖酸可有效防止銅、鉛、鎳等重金屬對(duì)魚類生長(zhǎng)和繁殖的危害，促進(jìn)魚類生長(zhǎng)加快。3添加腐植酸。2餌料中適當(dāng)加大維生素C添加量。夏季可在魚池距水面20厘米處安裝60瓦燈泡誘蟲入池，大力推行采用價(jià)廉的餅類和糠麩等，替代或少用價(jià)高的魚粉，豆粕等配料，這樣可大幅降低餌料成本。Second, save production costs. 飼料費(fèi)用一般約占養(yǎng)魚成本的60%以上，
