Assessing stocks of (Hamilton, 1822) from three different management systems in (Oxbow lake) of southwest Bangladesh: Implications for sustainable management.

This study was conducted to observe the stock assessments of in three different management systems of (Oxbow lake) such as System-1, System-2, and System-3. In this study, 1806 specimens were sampled using traditional fishing nets to observe growth pattern, population structure, growth parameters, natural mortality (), fishing mortality (), total mortality (), recruitment pattern, exploitation rate (), relative yield per-recruit (), optimum catchable length, length at first capture, steady state biomass (), and maximum sustainable yield () from January to December 2021. Digital slide calipers and a digital balance were used to measure each individual's total length () and body weight (), respectively.

Association of Gene Mutation With Infection in Gastric Cancer Patients and Its Correlation With Clinicopathological and Environmental Factors.

Background: Gastric cancer is also a leading cancer in Bangladesh like that of the global incidences. It is speculated that environmental, bacterial infection and molecular factors might have been carrying the key role of rising trend of the disease. This study was aimed to investigate the association of mutated gene with of () infection, clinicopathological and some environmental factors of the gastric cancer patients.
