Course Objectives

  • To provide holistic knowledge on fish and shellfish pathogens and their control measures

Course Outcomes

CO1-Understand Stress in aquaculture and its role in disease development:PO1, PO2

CO2-Knowledge on various Pathological processes: PO1, PO2

CO3-To understand Role of physical, chemical, and soil and water parameters in fish health: PO1, PO2

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.
