Zoo.323 Aquatic Biology 3+1

LEARNING OBJECTIVES:

The primary objective of this course is –
 This course offers a comprehensive knowledge on life in freshwater and marine
environments; lakes; stream and their characteristics, adaptations of organisms, water
resource management; nutrient cycling; major threats to aquatic systems, pollution, and
eutrophication.
 To impart knowledge and understanding of basic laboratory equipment and practice of
water quality analysis, to study of aquatic plants.
 To introduce various freshwater and marine ecosystems and its components.
 To understand the biodiversity and productivity of freshwater and marine environments.

LEARNING OUTCOMES:

This course will enable the students to:
 Be acquainted with the physico-chemical environment, and its role in aquatic ecosystem.
 Learn about adaptations unveiled by organisms to survive in these distinctive conditions.
