The results showed that environmental factors such as temperature, pH, N-NH3 and N-NO2 were within the suitable range for growth and color of Koi fish. Survival rate ranged from 46.67 to 66.67% (p> 0.05). Growth in length (15.26 - 15.55 cm) and weight (47.31 - 48.39 g) did not differ significantly between treatments (p> 0.05). Feed conversion ratio (FCR) between treatments was not different. The fish color index in NT3 was significantly higher than the others.  Therefore, the content of 65 mg/ kg of food resulted in best color of Koi fish.","PeriodicalId":21692,"journal":{"name":"Scientific Journal of Tra Vinh University","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82312091","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 the context of deeper integration, Vietnamese enterprises are facing competitive pressures in the domestic market. Thus, to take advantage of opportunities and respond to challenges, Vietnamese enterprises need to focus on building a workforce that is keenly aware of the challenges and opportunities of the AEC. This will help consolidate and improve their competitiveness. However, Vietnamese companies and their employees have not been unready for the AEC yet. The lack of  information about the AEC and the instructions become a major obstacle to the economy. The purpose of this research is to measure level of knowledge of the youth about the AEC and estimates its impact on their awarenesss of opportunities and threats related to the AEC. Results from the survey of 214 young  employees show that Vietnamese youth are confident of their subjective knowledge of the AEC, but their objective knowledge of the AEC is quite low. The youth recognized many opportunities and challenges brought by the AEC.
