Place and Duration of Study: Nijhum dwip declared as marine protected area is blessed with unique ecosystem with holding numerous flora and fauna species diversity. Data and fish sample were collected from February, 2019 to July 2019 for a period of five month. Methodology: The current research was grounded on visiting fish landing center and fish market, on spot date collection, interview of the fishermen and the fish traders, sample collection and secondary data collection. Results: In investigation, 39 species in 22 families were witnessed. The maximum numbers of fish species (8) were observed from the family Cyprinidae. From the survey, 4 species were endangered (EN), 5 species were vulnerable (VU), 2 species were near threatened (NT), 22 species were least concern (LC) categories, 6 species were not threatened (NO) which is grounded on IUCN (2015) list of threatened fishes of Bangladesh. The marine fish and freshwater fish alignment in the research region were 33% and 67% in turn. Conclusions: The species scarcity or decline is demonstrated by the non-availability and less availability of some of the species in the adjacent area as well as in the country. The policy makers, Original Research Article Khalil et al.; JAERI, 22(1): 17-25, 2021; Article no.JAERI.66025 18 researchers as well as local people would be able to aware with their existing biodiversity status and also significance of fish fauna of the study area by appropriate evaluation and proper documentation of fish fauna.

This Upazila is very close to Gumti River. Data were collected from randomly selected 40 respondents of local fishermen community through questionnaire interview. The study was performed on the basis of personal interview and Focus Group Discussion. From the survey, it was estimated that most of them are directly or indirectly involved in fishing. They are engaged in different fishing-related activities during banning season. The study shows that the majority (66%) of fishermen were Hindu, where 34% were Muslim. The literacy rate was only 18% here. The research indicates that 70% of fishers directly involved in fishing. They were provided license card from Upazila Fisheries Office. Their jointed family was 70%. Most of them live in a tin shed house which is 90%. The survey also informed that most of the fisher, like 80% use tube-well for drinking water. Treatment facilities were developed, but it depends upon their economic condition. Poor fishermen go to village doctor and kabiraj for treatment. Comparatively wealthy fishermen go to Upazila Health Complex and Sadar hospital in serious condition. In the study area, there were no training facilities for local fishermen. Sometime they could not get enough loans for lack of proper management program. As a result, fishers became helpless while flooding occurs. Electricity facilities in the study area were better than before. Annual incomes of the fishermen were varied from BDT 50000-100000. Except fishing, fishermen were involved in net making, boat construction, agricultural activities etc. The government should come forward to take necessary steps to manage their problems and to motivate them for creating significant opportunities for their better livelihood structures.

Methodology: A questionnaire interview survey was conducted among 14 aquaculture farms and 23 aqua chemical retailers. Results: Due to easy availability, farmers used large quantities of lime and cow dung to prepare ponds and manage water quality. Beside these rotenone, zeolite gold, acme's zeolite, aqua kleen, urea and TSP (triple super phosphate) are also found. Timsen, polgard-plus, deltix, virex, magic-fos and pond-safe were mostly used as a disinfectant. Epizootic Ulcerative Syndrome (EUS) disease was found predominantly in the farmer's pond. For disease treatment, renamycine soluble powder (oxy tetracycline) was used, 32% farmers. Two oxygen suppliers oxy gold and oxy life were used to increase oxygen concentration. Among 11 types of growth promoters were found in chemical shops Singha et al.; AJOB, 10(4): 22-31, 2020; Article no.AJOB.63384 23 in which charger gel and rapid grow were mostly used. Most farmers use gas trap and gasonex plus as gas reducer. Conclusions: There are mostly six categories of 48 aqua drugs and chemicals are observed and treated for health monitoring of fish and shellfish. Due to lack of knowledge concerning the proper dosage and procedure of using chemicals, technique of application and indiscriminate practice of chemicals etc. are common problems of aqua drugs in Moulvibazar district.

The study was conducted from March 2015 to December 2015 in different Upazillas of Noakhali district. The information was collected through questionnaire based interviews and Focus Group Discussion and compared that with secondary information of prawn farming in the area. The prawn farming has been promoted in greater Noakhali districts through development partners and Non-Governmental Organizations. Farming technique in this areas were mainly mixed, poly-culture and integrated culture types. An area of 149 ha which is 0.58% of the total area of the district was used for prawn farming. During the project period of RFLDC DANIDA, the prawn farming was reportedly flourished and a supply chain system of produced prawn from farming areas to processing plants was also established. However, with the withdrawal of project support shows a steady decline from its peak from 144.94 ton to roughly 50 ton in the recent time. Even the post larvae (PL) production was drastically reduced to 2 lakh in 2015 from 43 lakh in 2013. Availability of hatchery produced PL, natural disasters, gap in information and knowledge on improved and high density farming, lack of awareness of health managements of prawn farming etc. were considered as the main obstacles of greater prawn production. Therefore, it is obvious that integrated prawn-fish-rice farming has a good prospect in this region but decline of subsidized input supply and hatchery produced PL stopped its pace of growth.
