The present study was conducted to know the biodiversity status and assess the existing livelihood conditions of the fishers of Habullah Baor at Bagherpara upazila, Jashore district from November 2017 to April 2018. Sixty fishermen were randomly selected for collecting data through a semi structured questionnaire. The current study discovered that there were 11 different fish species from six orders and seven families in the Habullah baor. All of the sampled fishermen were Hindu. About 25% of the fishermen was young aged, majority was middle aged and 25% was old aged group. A total of 75% of the fishermen had nuclear family and 25% families lived in joint family. Among the fishermen 85% had a few decimal of cultivable land and 15% were truly landless. Annual income of the respondents varied from 30,000 to 70,000 BDT with an average of 42,833 BDT. All fishers had access to drinking water from tube wells. Most of the fishers lived in katcha houses. About 15% of the fishers enjoyed electricity facilities in their home. Among the fishermen investigated, majority had earthen latrine, 20% used tin shed latrine, 8% used concrete latrine and a few of them 10% had no latrine. There were no modern medical facilities in the villages. The respondents had no alternate income sources during the dry season and at the time of ban period. The fishers as a whole are leading measurable life due to great financial hardship. Proper conservation and management measures can be taken to enhance the availability of fish fauna in Habullah baor, so that, the fishermen can harvest ample fish on sustainable basis. Asian J. Med.

Abstract:The study was conducted at Ma-Fatema Fish Hatchery in Jessore from January to March, 2016. The present study was emphasized on water quality parameters, feeding management and cost-benefit analysis. The water quality parameters temperature ( 0 C), pH, dissolved oxygen (DO) (mg/l) and transparency (cm) were measured by Celsius thermometer, pH meter, DO meter and secchi disk, respectively. The proximate composition of feed ingredients was determined by the Association of Analytical Chemists, 1980. Brood fishes were reared all year round in the brood ponds by supplying formulated feeds. Temperature was 19 o C -26°C in brood ponds and 18 o C-24 o C in hatching jars; pH was 6.93-7.87 in brood ponds and 6.79-7.54 in the hatching jars; dissolved oxygen was 4.8-6.3 mg/l in brood ponds and 4.8-6.7 mg/l in hatching jars; transparency was 14-18 cm in the brood ponds. The percentage of farm made feed was protein (27.76%), lipid (4.9%), CHO (18.62%), ash (11.31%), fiber (6.4%), moisture (31.01%). The cost benefit ratios were 1.54, 1.32 and 1.23 and net profits were BDT 49911.67, BDT 24816.67and BDT 16366.67 respectively in January, February and March. Management of brood fish by providing quality feed and physico-chemical parameters of water were maintained in according to scientific procedure. Cost-benefit ratio of the hatchery in common carp production was satisfactory.

Abstract:The study was conducted on Bergobindapur baor at Chaugachha upazila under Jessore district. The study period was February to June, 2015. Data were collected by using participatory rural appraisal (PRA) tools and personal observation. Net return was loss in 2013-2014 and the loss amount was BDT 254200. Cost benefitratio in 2013-2014 was 0.99. Major income (83.30%) of the fishermen community was drawn from the fishery activities of Bergobindapur baor. In 2014-2015, average income of fishermen was BDT 25250 during the fishing period. Within the household of fishermen community, the expenditure for food was 19%, clothing, 3%, children's education, 19%, medical, 3%, dowry and religion, 33%, agriculture, 13% and others, such as business, accommodation, sanitation etc. 10%, which came from baor activities. The findings of this study indicated that Bergobindapur baor plays a vital role for the support of livelihood of fishermen and net profit from baor was not satisfactory. A long-term strategy should be developed to make the baor profitable. The developed strategic plans should be initiated immediately for the profitability of the baor as well as improving the livelihood conditions of the fishermen engaged with the boar fishery activities.Keywords: economic analysis; baor fishery activities, impact on fishermen IntroductionJessore district has a large number of ponds, rivers, marches, baor, beel and total fish production from Jessore was 70426 MT during 2010 -11 (BBS, 2013. A baor is ox-bow lake, which is the still part of the flood plain of river connected by inlets and outlets. By screening the inlets and outlets a baor can be converted into a culture based fishery (DoF, 1996). Fisheries sector employed about 1.3 million full time fishermen and 12.5 million part times (DoF, 2013). Livelihood support could have various meanings, ranging from livelihood provision, to protection, recovery and promotion (Maxwell, 1999). The average rate of production from baor was 633kg/ha which can be increased manifold (DoF, 2011). Abdullah-Bin-Farid et al. (2013 found that socio-economic conditions of fishermen of the Baluhar baor was 58% lived in joint families, 78% used kancha (un-hygenic) sanitary latrine, 58% having 0.041 hectare lands and 74% lived in kancha (earthen) house. Das (2014) reported that total benefit from Bergobindapur baor was BDT 7135363.5 in the year 2012-13. From the above reviews, it was understood that the study on baor was limited and there were no research works about how baor had impacts on rural fishermen in the aspect of Bangladesh. Thus the present study was very important and it will

Global climate change has triggered the increased incidence of extreme disasters like cyclone, flood, soil salinity, etc. in the coastal region of Bangladesh. In the recent past, an amplified number of fatalities happened and the greater impact also acted upon the attitude of coastal people. Badarpur Union under Patuakhali Sadar upazila of Patuakhali District was the selected locale of the concerned study. Data for this research work were personally collected from a randomly sampled 121 farmers from different villages of Badarpur union by using an interview schedule. Attitude of the farmers was ascertained through a five-point-Likert type scale. Co-efficient of correlation (r) was computed to explore the relationships between farmers? attitude and their selected characteristics. The findings revealed that 51.2 percent of the farmers had moderately favourable attitude towards climate change effect while 42.1 percent had slightly favourable and 6.6 percent had highly favourable attitude. The correlation test showed that the education, farming experience, farm size, annual income, training received and agricultural knowledge had positive significant relationships with farmers? attitude towards climate change effect on agriculture while the rest of the characteristics had no relationship in the present study. The focus findings of the present study were that, the attitude of the farmers is changing due to changes in the climatic conditions and there was a positive effect of it on agriculture.Asian J. Med.

Stimulating hormone for artificial fish breeding in hatchery industry is very crucial for hatching operation, healthy fry and fingerling production, while overall fish production of a country. The present study was conducted to assess the effectiveness of using local and overseas Carp Pituitary Gland (CPG) in the induced breeding of Cirrhinus mrigala at Jashore district from April to May 2022. The first dose of hormone, both for male and female brood fishes were injected with local and overseas CPG at 0.5mg/kg body weight. After six hours of the first dose, only female brood fishes were injected with the second dose of PG at 5 mg/kg body weight. After 6 hours of second dose CPG injection of local and overseas PGs, brood fishes started spawning. The ovulation rates for both local and overseas PGs were estimated 100%. The fertilization rates were 93.5 % and 92.6 % for local and overseas PGs; while the hatching rates were 91.2% and 89.5%, respectively. However, local CPG is highly recommended to hatchery owners considering the rate of fertilization, hatching rate and availability. Asian J. Med. Biol. Res. 2022, 8 (3), 146-153
