为充分了解微生态制剂的使用效果,2014年山东省荷泽市牡丹区畜牧兽医水产局选取主养草鱼的刘寨水产养殖小区2个条件相近的池塘作为试验池和对照池,作为对比试验的养殖场。使用的微生态制剂为山东君德生物科技有限公司生产的EM原液。通过对比试验和广大养殖户反馈的信息来看,使用微生态制剂可以显著改善水体环境,既提高水体透明度和溶解氧,又可减少鱼病的发生。 In order to fully understand the effect of using probiotics, two ponds with similar conditions in Liuzhai aquaculture district of main grass carp were selected as the test and control pools in 2014 by the Animal Husbandry and Veterinary Bureau of Fisheries of Mudan District, Heze City, Shandong Province Farms. The probiotics used are EM stock solution produced by Shandong Junde Biotech Co., Ltd. Through comparative tests and feedback from farmers, the use of probiotics can significantly improve the water environment, which not only improves water transparency and dissolved oxygen, but also reduces the occurrence of fish diseases.
