【正文】 ter all the year round, according to market sale, sell a good price. Can be put a foot, big sales. Herding of large size also can be repeatedly species, chasing after little sleep. To keep enough water fish loads, all the year round to keep balance, according to the price of fish volatility, flexible, improve business efficiency. (2) is a variety of fish, shrimp, etc. Rotary culture. Such not only can flexibly choose aquaculture varieties according to the market, also can reduce the bottom quality deterioration degree, reducing disease spread. If some producers with a pond in the first half of the South American white shrimp, the second half of a carp, can not only improve the economic efficiency, and reduce the happening of the disease, the effect is good, is worth using for reference. 四、加強(qiáng)魚病防治。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。一些養(yǎng)魚戶平時(shí)沒有提前作好魚病預(yù)防，當(dāng)魚病發(fā)生后又沒有及時(shí)對癥下藥，造成一定的損失，使養(yǎng)魚效益下降。綜合分析魚病的發(fā)生原因，采取相應(yīng)的對策，實(shí)行魚病綜合防治是提高養(yǎng)殖效益的必要措施。防病的原則是“預(yù)防為主，防重于治，及早診治，嚴(yán)格消毒”。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。此外用大黃、五倍子、大蒜、馬齒莧等中藥對防治魚病有良效。In recent years, explosive fish disease to a great extent, restricts the development of fishery production. Some fish at ordinary times didn39。t make fish disease prevention in advance, when after the occurrence of fish diseases and did not suit the remedy to the case in time, caused a certain loss, decreased fish farming efficiency. Comprehensive analysis of fish disease causes, adopt corresponding countermeasures, implementing prehensive prevention and control of fish disease necessary measures is to improve the breeding benefit. Prevention principle is prevention first, focus on prevention, early diagnosis and treatment, strict disinfection. Fish pond should be pletely clear pond with medicine。 Species range strictly sterilized before。 Fish onset season regularly with drug prevention。 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)效益和社會效益。Anyhow, aquaculture is a plicated and system engineering, it involves many problems, so only strengthen theoretical guidance and technical innovation, to achieve the economic benefits of aquaculture and social benefi
