Course Name : Physiology of Finfish and Shellfish
Course Code(Credit) : FSRM 2105 (2-1-0)
Program Outcome
PO1: Knowledge enhancement: Enhanced knowledge on concepts, essential facts, basics, principles and theories relating to fishery biology, biodiversity and aquatic environment, aquaculture, fish nutrition, fish physiology, genetics and biotechnology, fish processing, fisheries engineering, fish microbiology, fishery extension, economics, and biostatistics.
PO2: Professional and Entrepreneurial Skill development: Understanding the value and processes of life-long learning and professional enhancement and entrepreneurship development.
PO3: Critical thinking: After identifying the assumptions from the subject, take informed actions to frame the thinking and check out the degree to which these assumptions are accurate and valid, and look at our ideas and decisions (intellectual, organizational, and personal) from different perspectives.
PO4: Problem Solving: solve the problems from concerned disciplines using the knowledge, skills and attitude acquired from various disciplines in fisheries science.
PO5: Environment and Sustainability: Understand the issues of environmental contexts and sustainable development.
PO6: Data Handling and computational skills: Collect, analyze and interpret biological and scientific data for the scientific and farming community with the help of computer-based programmes.
PO7: Communication & Extension Skills: Develop appropriate communication skills for effective transfer of knowledge and technologies through extension activities.
PO8: Team Work: Play effective roles in capture, culture, management, financial and marketing of fish produce.
PO9: Ethics: Application of ethical principles and commitment to professional ethics and responsibilities.
