However, the aquatic ecosystem in which they live is constantly polluted. Microbial and proximate compositions and energy value of T. adansonii were evaluated as indices for food safety and biomarker of pollution. Standard microbiological techniques and standard methods of AOAC were employed. Results showed that Bacillus substilis, Micrococcus sp, Proteus sp, Klebsiella sp, Staphylococcus aureus, Vibrio cholerea, Vibrio parahaemolyticus, Enterobacter sp, Escherichia coli, Bacillus cereus, and Chromatium sp were the probable bacteria while Rhizopus stolonifer, Aspergillus niger, Penicillium sp. Candida tropicalis, Fusarium sp. and Aspergillus flavus were the probable fungi isolated from the sample. Total Heterotrophic Bacterial Count (THBC), TVC, TCC, TSC and TFC in fresh sample were 2.01±0.14 x 105, 2.77±0.27x10, 2.79±0.81x10, 6.08±0.21x102, and 2.08±0.21x104 cfu g-1 respectively and concentrated mostly in the gut.

The highest alterations in the studied antioxidants were observed in the fish exposed to C4 combination of the anaesthetics and the lowest in the control. The results from this work therefore suggest that the anaesthetics can alter antioxidants levels in the fish which was more noticeable in the fish exposed to C.N 3:1- 75% Clove and 25% Nutmeg; C.N 2:2- 50% Clove and 50% Nutmeg; C.4 - 100% Clove; N4- 100% .

The littoral and limnetic zooplankton assemblages of this subtropical reservoir without aquatic vegetation reveal total 36 species, and record lower abundance, quantitative dominance of Rotifera, sub-dominance of Cladocera and Copepoda and moderate species diversity. Keratella cochlearis, Bosmina longirostris, Polyarthra vulgaris, Mesocyclops leuckarti, Conochilus unicornis and Asplanchna priodonta influence abundance, species diversity, dominance and equitability of zooplankton. We report differential spatial influence of individual abiotic factors with the relatively more importance at the limnetic region, and the canonical correspondence analysis registers 72.5% and 78.8% cumulative influence of 10 abiotic factors on the littoral and limnetic assemblages, respectively. The spatial differences of various diversity aspects and the influence of abiotic factors suggest habitat heterogeneity amongst the two regions. This study is a useful contribution to zooplankton diversity of the subtropical environs, and soft and de-mineralized waters in particular. Our results mark a distinct contrast to the lowest richness and abundance of zooplankton noted from India vide the preliminary 1990-91 survey of this reservoir.","PeriodicalId":15784,"journal":{"name":"Journal of Fisheries and Aquatic Science","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75812244","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}

Currently, the commercial actors are involved in the aquaculture systems due to the availability of production technologies and inputs. This paper aims to explore how the commercialization and privatization of floodplain aquaculture become the cause of the sufferings of the natural resource-dependent people and biodiversity loss in the floodplains. Now, Influential people hold control of the common pool floodplains and restricted the access of the Small-Scale Fishers (SSF) to manage the aquaculture. Our findings suggest that the SSF, for whom the seasonal floodplains were an important source of livelihood, their livelihood has been destroyed and overall wellbeing have been negatively affected. Besides that, lending enough evidence to the increased inequality, a new group of poor has emerged. Because instead of ensuring the welfare of SSF, Bangladesh government has leased the floodplain lands to the powerful rich people. In addition to growing inequalities, natural resource degradation has welcomed social vulnerabilities. However, no development initiative will ever be sustainable and effective if the existing socio-ecological setting is not considered. Bangladesh government should take robust attempts to revisit fisheries policies to ensure livelihood resilience of fisheries resource-dependent community by managing the access rights of the common pool resources.","PeriodicalId":15784,"journal":{"name":"Journal of Fisheries and Aquatic Science","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76012409","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}
