Course Title: Responsible Fishing
Contact Hours: 2.0
Level: 1, Semester: 1
Fisheries resources are under tremendous pressure caused by over-exploitation that resulted in decrease in fish catch and even extinction of fish species. In developing countries like Bangladesh, small-scale and artisanal fishers sometimes turns to destructive fishing techniques that further degrades the situation, threats the aquatic ecosystems and finally results in dwindling livelihoods. To overcome this situation, there is a need to create responsibility towards the environment, invest in sustainable management of fishing resources and respect social laws and security for the sustainability of fishing industry. This advanced course of “Responsible Fishing” will provide the student with the ability to identify the reason behind responsible fishing and take measure on: selectivity of fishing gears, stopping overfishing through establishment of science-based catch limits, improving selectivity and stock control, reducing waste of by-catch, maintain the ecosystem, limit pollution, loss of gear and recommend mitigation measures to minimize impacts within selected fisheries.
Intended Learning Outcomes (ILOs):
Through this course, students will:
1. Gain knowledge on ecological impacts of fishing on freshwater and marine environment including by-catch, seabed interactions and ghost fishing
2. Acquire knowledge on how to maintain ecosystem balance and improve production of fish stock
3. Be able to establish science-based catch limits for open water fisheries including hilsa
4. Acquire knowledge to take actions on reducing catch of non-targeted species
