摘要
通过对改造后池塘运用微孔增氧、生物防病和微生态调水等技术,进行凡纳滨对虾的设施化养殖。结果表明,微孔管道增氧能极大地提高水中的溶氧量,并且充气均匀;微生态制剂调水也保证了水体的健康环境;生物防病技术由于在品种选择、投放密度和规格等方面存在一定问题,最终导致对虾白斑病的暴发。经过一年的实施,虽然经济效益亏损,但为今后该技术的实施提供了技术参考。
This article presented that facilities cultivation shrimp in transformed ponds by the technique of microporous aeration, biological prevention and probiotics. The results showed that microporous aeration pipes could greatly improve the amount of dissolved oxygen, and inflatable uniform;control water by probiotics also ensured a healthy environment;there were many problems on biological prevention techniques due to species selection, density and specification, eventually leading to an outbreak of white spot disease. After a year the trial although economic losses, but valuable experience supplied a lot of technical reference.
