Altered microbial communities due to the application of probiotics were studied using 16S rRNA-based Illumina sequencing. The results suggest that the probiotics-treated group showed higher richness; the control group was even as measured by alpha diversity indices. The abundance of Proteobacteria was higher in the probiotic-treated group (94.85%) compared to the control (58.29%). At the genus level, the probiotics group was dominated by Vibrio (44.17%), Rhodobacteraceae_unclassified (25.22%), Catenococcus (12.89%), Pseudoalteromonas (4.76%), and Kordia (1.53%); Tenacibaculum (24.29%), Catenococcus (19.38%), Vibrio (7%), Gammaproteobacteria_unclassified (6.6%), Fluviicola (5.91%), and Chlamydiales_unclassified (4.61%) dominated in the control group. Results indicate that probiotic application influenced the taxonomic profile of gut microbes. This information helps us to understand the effect of probiotic application especially in penaeid shrimp hatcheries.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":"35 1","pages":"622 - 632"},"PeriodicalIF":1.2,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49433222","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}

A high plant-ingredient basal diet was supplemented with exogenous xylanase at 0 (Control diet), 100, 150, and 200 ppm, and fed to on-growing (initial weight ca 500 g) fish for a duration of 91 days. Growth parameters, fillet proximate composition, hindgut microbial diversity, hindgut short-chain fatty acid concentration, and blood chemistry parameters were monitored. There were no effects on growth parameters, fillet proximate composition, hindgut short-chain fatty acid concentration, and blood chemistry parameters. Dietary xylanase supplementation caused a significant shift in hindgut microbial diversity, where the 200 ppm treatment showed significantly lower Shannon diversity (2.15 ± 0.13) than the control (2.78 ± 0.21). The significantly lower microbial diversity indicates that enzyme supplementation selectively benefitted certain microbial populations in the hindgut, presumably through the release of prebiotic compounds during non-starch polysaccharide hydrolysis. It is concluded that dietary xylanase supplementation can significantly impact hindgut microbial communities in on-growing African catfish, and it is recommended that future work investigate whether dietary xylanase supplementation can benefit aquaculture production performance in younger fish.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":"35 1","pages":"561 - 584"},"PeriodicalIF":1.2,"publicationDate":"2021-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42813987","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}

The aims of this study were to examine the efficiency of inducing triploid mussels by various treatments and to determine the effect of triploidy on larval development. To produce triploids, extrusion of the second polar body of fertilized eggs was inhibited by 6-(dimethylamino)purine (6-DMAP), cold-shock, or heat-shock treatments. Triploidy was detected by flow cytometry for all the treatments. Treatment with 6-DMAP was the most efficient with a rate of triploidy of 90%, followed by heat-shock (56%) and cold-shock (30%) treatments. No survival differences were observed between diploids and 6-DMAP-induced triploid larvae from the D-shape stage up to their settlement. Moreover, increased growth was observed in triploid larvae compared to diploid larvae. Overall, this study showed that 6-DMAP is a highly efficient method to induce triploidy in mussels, with triploid larvae having faster growth compared to diploid.","PeriodicalId":15031,"journal":{"name":"Journal of Applied Aquaculture","volume":"35 1","pages":"473 - 488"},"PeriodicalIF":1.2,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47530161","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}

A 30-day feeding trial was conducted in order to investigate the effect of the different feeding schemes: AT- Enriched Artemia meta-nauplii + Thalassiosira pseudonana; RAT- Enriched rotifers + enriched Artemia + T. pseudonana; CAT- Apocyclops panamensis copepodites + Enriched Artemia + T. pseudonana; STR- under starvation, upon growth, survival, and development of L. amboinensis larvae. Larvae in the CAT and STR treatments survived for over 3 days, however, total mortality occurred before day 6 in both treatments, whereas in RAT, larvae had an average survival (± SD) of 68.3 ± 12.5% by the end of the trial and those in AT showed a survival of 30.0 ± 5.0%. Development rate was also higher in RAT, where 44.3 ± 13.8% of the larvae were able to reach the zoea X stage by the end of the experiment. Among the larvae in AT, 88.5 ± 10.3% of them were at the zoea IX stage and a small percentage of the larvae were still at the zoea VIII stage on day 30. Growth in AT (2.02 ± 0.33 mm) was lower than in RAT (3.50 ± 0.26 mm).
