以芽孢杆菌为主导菌的化能异养细菌和光合细菌是从自然界中筛选、分离、诱导、强化培养得到的活性有益微生物。微生物制剂在暗纹东方鱼屯养殖中的应用结果,表明微生物制剂能促进优良单细胞藻类的生长,营造良好水色,氨氮、亚硝酸盐、硫化物的含量降低,水体环境得到了改善。光合细菌是河鱼屯初孵仔鱼优良的开口饵料。 The heterotrophic bacteria and photosynthetic bacteria which take Bacillus as the leading bacterium are active beneficial microorganisms which are screened, isolated, induced and intensified in nature. The application results of microbial agents in the culture of Takifugu obscurus showed that microbial agents can promote the growth of excellent unicellular algae, create good aqua, ammonia nitrogen and nitrite, reduce the content of sulfide and improve the water environment. Photosynthetic bacteria is an excellent fish feed opening hatchery River fish.
