B.Sc Marine Biology is an undergraduate programme designed to study life in oceans and coastal environments, ranging from microscopic plankton to marine mammals, corals, and commercially important fish and shellfish. The curriculum typically combines core biology (cell biology, genetics, microbiology, biochemistry) with specialised marine subjects such as marine ecology, marine biodiversity, oceanography, fisheries science, aquaculture, marine pollution, and conservation biology. Practical training is a key element, including laboratory techniques (microscopy, water and soil analysis, basic molecular methods), taxonomy, field sampling, data recording, and report writing. Many colleges include field visits to coasts, estuaries, mangroves, fish landing centres, hatcheries, and research facilities to expose students to real-world marine systems. After completing the degree, students can pursue careers in marine research support, environmental consultancy, fisheries and aquaculture operations, coastal biodiversity projects, and NGOs working on marine conservation. For research-focused roles, higher qualifications (M.Sc/Ph.D.) are generally preferred, but the UG degree provides the essential scientific base and practical exposure.
