复合微生物制剂菌种选择及其对大口黑鲈养殖水质、生长性能和血清生化指标的影响
Selection of compound microbial preparation strains and its effects on water quality,growth performance,and serum biochemical indexes of Micropterus salmoides
摘要
Abstract
The experiment was to study the effects of compound microbial preparation on the water quality,growth performance,and serum biochemical indexes of Micropterus salmoides.From the six strains of probiotics,four strains with strong water purification capacity were screened:Bacillus licheniformis CICC 23433,Bacillus subtilis CICC 22060,Rhodopseudomonas palustris CICC 23812 and Lactiplantibacillus plantarum 6026 were prepared into a compound microbial preparation.A total of 240 Micropterus salmoides with an initial weight of(86.58±0.81)g were randomly divided into two groups with six replicates per group and 20 fish per replicate.The control group did not use compound microbial preparation,and the experimental group was sprayed with 1 kg of compound microbial preparation fermentation solution every 667 m2 of water surface(1 time/10 d).The experiment lasted for 60 days.The results showed that compared with the control group,on the 60th day of the experiment,the transparency of aquaculture water in experimental group increased by 70.03%,dissolved oxygen content increased by 16.78%,nitrite content decreased by 91.96%,potassium permanganate index decreased by 43.36%,ammonia nitrogen content decreased by 85.88%,and total nitrogen content decreased by 12.23%,the total phosphorus content decreased by 42.50%.Compared with the control group,the weight gain rate of experimental group was increased by 7.33%,the survival rate was increased by 6.48%,and the specific growth rate was increased by 4.44%(P<0.05).The concentrations of total protein(TP),albumin(ALB),low density lipoprotein cholesterol(LDL-C),high density lipoprotein cholesterol(HDL-C)and alkaline phosphatase(ALP)in serum were increased by 5.91%,8.53%,29.74%,33.95%and 7.89%compared with the control group,respectively(P<0.05).The results showed that adding compound microbial preparation in aquaculture water can effectively improve the water quality,regulate the immune function of Micropterus salmoides,increase the survival rate and improve the growth performance of Micropterus salmoides.关键词
