Abstract:The changes of water quality in the ponds and greenhouses cultured Siniperca chuatsi were investigated and analyzed by the ecological experiment method in this study. Meanwhile, the regulation effects of different microecological products(photosynthetic bacteria, Bacillus subtilis and lactic acid bacteria) on the water quality cultured S. chuatsi were studied. The results showed that there was no significant difference in water temperature, dissolved oxygen and pH between the greenhouse culture mode and the pond culture mode throughout the breeding cycle of S. chuatsi(from seedling to commercial fish). The change rule of three nitrogen(ammonium nitrogen, nitrate nitrogen and nitrite nitrogen) in greenhouse culture mode was roughly the same as that in pond culture mode, but the former had higher content in most of the time. The total phosphorus content of greenhouse culture mode was higher than that in pond culture mode, and its the maximum value of total phosphorus was delayed by nearly one month. Photosynthetic bacteria had the best overall regulation effect on ammonia nitrogen, nitrite nitrogen and total nitrogen in mandarin fish culture water. Bacillus subtilis had good effect on reducing nitrate nitrogen and nitrite nitrogen. Lactic acid bacteria had certain improvement ability to reduce water pH in the later period of culture. In conclusion, compared with the pond culture mode of mandarin fish, the circular conversion efficiency of nitrogen and phosphorus substances in the greenhouse culture mode was lower, and the reasonable use of microecological preparations to regulate water quality was more effective. At the same time,it was necessary to pay attention to the influence of adverse weather on the effect of probiotics.
Keywords:Siniperca chuatsi  water quality  microecological preparation  breeding mode
