Experiments were conducted for two continuous cycles without water exchange for 30 days during the nursery stage. The studies were performed with two different aeration systems, namely microbubbles (MB) and large air bubbles (LB). Water quality parameters such as dissolved oxygen (DO), temperature, pH, salinity, alkalinity, total ammonia nitrogen (TAN), nitrite, nitrate, settleable solids (SS), and total suspended solids (TSS) were recorded throughout the culture days. Also, comparisons were performed on parameters of the shrimp growth, i.e., body weight and length, feed conversion ratio (FCR), and specific growth rates (SGR) for the 30-day culture for Cycles 1 and 2. Cycle 2 showed no deterioration in water quality and no significant difference in growth performance compared to Cycle 1 for either aeration method (MB and LB). However, when comparing between aeration methods, MB aeration significantly improved the DO of the water and accelerated the conversion of TAN to nitrate. Shrimps in the MB aeration system were significantly larger (by 39%) with a lower FCR value (reduced by 30%) than in the LB aeration system. Harmful bacteria from the <em>Vibro</em> group were detected. However, they occurred at a minimum level in both cycles and aeration types. Overall, the biofloc-culture water might be reused for the subsequent cycle, while the MB aeration might promote the growth of biofloc and <em>L. vannamei</em>.</div></div>","PeriodicalId":36894,"journal":{"name":"Aquaculture and Fisheries","volume":"10 4","pages":"Pages 687-695"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141026331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we screened peanut varieties that were resistant and susceptible to <em>A. flavus</em> and evaluated their nodulation ability and growth performance after ARC microbial inoculants treatment in the field. The results demonstrated that the nodule number and nitrogenase activity of both varieties significantly increased after ARC microbial inoculants treatment, with the highly susceptible variety AH24 showing a greater increase. For photosynthetic parameters, both varieties also increased after ARC microbial inoculants treatment, but the increase was greater in the moderately resistant variety AH1 than in the highly susceptible variety AH24. Finally, we found that the yield and yield-related traits of the moderately resistant variety AH1 were better than those of the highly susceptible variety AH24. After ARC microbial inoculants treatment, the yield traits of both peanut varieties still increased significantly, but the degree of increase of the moderately resistant variety AH1 was smaller than that of the highly susceptible variety AH24. In addition, the abundance of <em>A. flavus</em> in the rhizosphere soil of the two varieties significantly decreased after ARC microbial inoculants treatment, with no significant difference between the varieties. These results indicated that ARC microbial inoculants exert differential effects on the nodulation and growth of different resistant peanut varieties and have a better effect on highly susceptible varieties.
