Explore the aquatic environment, its importance in understanding climate change, and how to monitor and protect marine and freshwater species in a sustainable manner.

The aquatic realm makes up more than 70 per cent of the Earth’s surface and represents the largest domain on earth. This course focuses on the study of the fascinating diversity of life contained in these habitats.

You’ll come to appreciate the issues involved in management of aquatic resources and learn how a firm understanding of the organisation of aquatic ecosystems can promote use in a sustainable manner.

Aquatic habitats and organisms are also pivotal in the understanding of climatic change making this course very relevant to a career in conservation and environmental protection.

For the environmental sciences we rank in the top 5 of all UK universities for teaching, learning opportunities and assessment and feedback (National Student Survey 2026).

READ MORE ABOUT OUR STUDENTS

I felt very inspired by our lecturers who often showed practical examples from their own research and always were very encouraging and enthusiastic.

Julia Jung

BSc (Hons) Marine and Freshwater Biology

Are you interested in global issues? Are you interested in the marine or freshwater environment? If it’s aquatic biology including coral reefs and sea birds that takes your fancy or indeed conservation and the impact of pollution on the aquatic environment, this is certainly a course worth joining.

You’ll study the adaptation, ecology and behaviour of a range of species found in marine, coastal and freshwater environments. You’ll learn about the non-living environment, including climate, weather, water and sediment properties and pollution. You’ll also learn about aspects of management, including pollution assessment and control and fisheries science.

Scotland is home to some fascinating aquatic environments and you’ll get to experience these during practical fieldwork, both locally and further afield, including a residential field course to the Isle of Cumbrae. For the past two years, we have also offered students the opportunity to complete subsidised RYA Level 2 powerboat training.

The course will equip you with a broad portfolio of skills in both specialist techniques such as species identification, surveying, data analysis and GIS along with communication of scientific information, IT, problem solving and team working which will allow you to pursue a range of possible career paths.

How you’ll be taught

You will learn through a variety of different methods, including lectures, tutorials, field studies and laboratory classes.

More than two-thirds of our permanent academic staff are Fellows of the Higher Education Academy, reflecting their dedication and formal training in teaching undergraduate students. Together with our accreditation by The Royal Society of Biology - which is your assurance of the quality and relevance of our course to the needs of employers - this is your assurance of the up-to-date knowledge of our teaching staff and guarantee of a supportive learning environment.

Assessments

A variety of assessment methods are used, including examination, assignments and practical assessments. These are balanced across the Programme to provide a challenging assessment experience, which allows you to do your best.

Study abroad

Erasmus opportunities. We have links a number of institutes, including Roskilde University, in Denmark, where students can study in English.

Placement and Study Abroad opportunities are subject to any current UK and Scottish Government health and travel advice.

Facilities

This course is taught in person at our Sighthill campus.

Careers & employability

What can you do with a Marine & Freshwater Biology Degree?

By studying Marine & Freshwater biology at Edinburgh Napier University, you will learn about the marine and freshwater species habitats, management of aquatic resources and, also learn about ecosystems and sustaining these for underwater life. On completion of the course, you will have become an expert in marine species as well as coastal and freshwater environments, with practical skills in aquaculture, fisheries management, and conservation. Roles you may consider working in include conservation, environmental protection, habitat and species management, pollution control and education. If you are interested in global issues, pollution and the freshwater environment, and are a keen problem solver and practical thinker then this might be the right course for you.

Gaining a degree in Marine and Freshwater gives you discipline specific knowledge and skills, but it is not restrictive. You will gain a range of highly desirable transferable (meta) skills, including communication, numeracy, computer literacy and data analysis, which are valued by employers within, but also outside the Life Science sector.

What does a Marine or Freshwater Ecologist do?

A marine or freshwater ecologist specialises in studying and monitoring the communities of animals that live in our aquatic ecosystems, from oceans and rivers to mangroves and reefs. You will carry out lab work, research and fieldwork on ecological communities, population changes and pollution threats. You will be an effective communicator, team player and critical thinker, with excellent writing and analytical skills.

Daily tasks and responsibilities you may have within this role include:

Ecosystem monitoring

Species identification

Data analysis and interpretation

Creating or advising on environmental policy
