Fish samples were collected monthly by bottom trawl.Fish stomachs were fixed in a 4% formol solution to prevent feed items from being digested in the stomach. The analysis of 198 male and 215 female samples showed that the total length (L) and body weight (W) of the fish had a regression relationship according to the equations Wmale = 0.0064L3;1425 and R2= 0.9735 (totallength ranged 14.0 – 40.0 cm) and Wfemale = 0.00463:2425 and R2 = 0.9504 (total length ranged 13.5 – 41.0 cm). The relative length of the gut (RLG) < 1 (RLG = 0.08 ± 0.02 cm in immature fish and RLG = 0.08 ± 0.04 cm in mature fish),indicated that Reeve’s croaker was a carnivorous fish. Many individuals in the population haveno food in their stomachs. The immature fish eat three types of food (small fish, shrimp and other food) while mature fish eat six types of food (small fish, shrimp, squids, crabs, nereid and other food). The feed spectrum of immature fish was narrower than that of mature fish.","PeriodicalId":159074,"journal":{"name":"TRA VINH UNIVERSITY JOURNAL OF SCIENCE; ISSN: 2815-6072; E-ISSN: 2815-6099","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133835963","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}

Many writers and poets are concerned about the reality of the environment happening in the delta, so they have integrated and included issues with a clearecological consciousness in their works. To answer the question of why eco-conscious literature appeared in the Mekong Delta, the article focuses on explaining the issues of natural, social, and cultural conditions and environmental changes. Ecology affects the sense and responsibility of the writer. Thereby, it shows that each region with different natural, cultural and social conditions has a more or less impact on the formation ofliterary characteristics in each region, especially for eco-conscious literature. A literary work expressing ecological consciousness often refers to environmental changes that have a negative impact on human life. The literary works relating to this issue mainly mention the consequences that people have suffered from climate change, soil, water, air, and flora or reveal people’s attitudes and feelings towards the situation they are witnessing. Therefore, the natural, cultural and social conditions and their changes directly affect the formation of a part of literature with ecological consciousness in this area.","PeriodicalId":159074,"journal":{"name":"TRA VINH UNIVERSITY JOURNAL OF SCIENCE; ISSN: 2815-6072; E-ISSN: 2815-6099","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129741865","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 liver and kidney of laboratory mice were separated from groups of normal mice drinking distilled water (physiological control), normal mice drinking 1000 mg/kg, normal mice taking 2500 mg/kg and rats taking5000 mg/kg b.w., only one time. The observed results showed that the microstructure of the liver/kidney of rats drinking methanol extract MIL were damaged when compared to physiological control mice. This means that high doses of MIL have adverse effects on the liver/kidney of normal mice.
