Course Name : Marine Biology

Code(Credit) : FSEM1205(2-1-0)

Course Objectives

  • Marine biology is the study of all aspects of life in the sea and the environment on which it depends. This includes marine plants, animals and other organisms, both vertebrate and invertebrate, in deep oceans, shallow seas and the laboratory.
  • The main aims of marine biology are to improve understanding of the marine world and to understand and predict changes in ecosystems affected by human and natural disturbances.
  • Marine biology is a broad-ranging career. You could go into field work, academic research, laboratory work, consulting, charity, outreach or policy making.

Learning Outcomes

  • In this Course, student will gain basic knowledge of the organisms found in marine waters, and on the interactions between environmental factors and biological processes in aquatic ecosystems
  • Food web and energy flow
  • Different ecosystems bordering the marine environment
  • Diversity of marine organisms
  • Animals in relation to physico-chemical properties of the marine environment

Course Syllabus

Introduction to Marine Biology: Divisions of marine environment- pelagic, benthic, euphotic, aphotic divisions and their subdivisions. Life in oceans - general account of major groups of phytoplankton, sea weeds, major zooplankton groups. Environmental factors affecting life in the oceans-salinity, temperature, light, currents, waves, tides, oxygen, and carbon dioxide. Vertical migration of zooplankton, Phytoplankton-Zooplankton relationship, geographical and seasonal variation in plankton production, plankton and fisheries. Inter tidal ecology: Rocky shore, sandy shore and mud flats, zonations, communities, and the adaptation. Mud banks: formation, characteristics. Estuaries: Classification, Physico-chemical factors, Biota and productivity, examples of some Indian Estuaries. Boring and fouling organisms. Nekton outline, composition of nekton, habitats of nekton. Bioluminescence and indicator species, Blooms, Red tides: cause and effects.

Study of common instruments used for collection of phytoplankton, zooplankton and benthos. Collection, preservation and analysis of phytoplankton, zooplankton, sea weeds, Collection preservation and analysis of inter tidal organisms.
