Employability

You will be fully supported with developing your employability skills throughout the degree scheme. The degree will allow you to develop specialist skills such as the ability to identify, either via own knowledge or dichotomous keys, marine and freshwater plants and animals as well as developing a range of transferable skills highly valued by employers. You will join a department that has excellent facilities to support your studies; £55 million pounds has been invested over the last five years in IBERS infrastructure. Many students as part of their supervised final year project have access to highly specialised facilities for example IBERS new marine and freshwater aquarium facilities. These facilities enable students to develop their specialist skills and knowledge preparing them for a successful transition into the workplace. Marine and Freshwater Biology students at Aberystwyth benefit from the unique biodiversity in west Wales which provides plenty of opportunities for extensive fieldwork to develop practical skills and knowledge.

IBERS staff have close links with many learned societies such as the Society of Biology which provide a route for students to network with others in their discipline and explore funding opportunities and recognition for their work. Guest lecturers and expert external teachers also contribute to the curriculum to pass on their expertise and knowledge.

The department has resources on the virtual learning environment, Aberlearn Blackboard to support your development and has a dedicated Twitter feed to keep students informed of developmental opportunities and work experience. Students have participated in a work experience module to help them identify and reflect on the employability skills they are developing through their work experience. 

The department has a close working relationship with the Careers Service who can help and support you sourcing work experience opportunities locally and nationally. Students from the department have participated in work taster opportunities in local secondary schools to gain experience of teaching science and the local wildlife trusts. You can also participate in the Year in Employment Scheme (YES) to gain graduate level work experience and IBERS students have successfully gained placements with a number of employers including Seacamp Environmental Education Camp in Key West, Florida and the Centre for Ecology and Hydrology.

On graduating with your BSc Marine and Freshwater Biology Degree you will be qualified for career-paths specifically related to the discipline. In addition, your degree will have taught you a broad range of skills such as observation, research, analysis and reflection which are demanded by employers in every field.

Teaching, Learning and Assessment

This modular degree scheme provides you with an integrated approach to the study of marine and freshwater biology. It aims to develop your understanding of the principles and concepts of aquatic biology, and to provide you with an insight into the complexities of managing aquatic habitats.

What will I learn?

The structure of the course may vary from year to year but the following provides an idea on what you may study. 

In the first year you will study biological molecules and cells, metabolism, and genetics. You will look at the major animal vertebrate and invertebrate groups, focusing on the physiology of these animals with respect to sensing the environment, muscle and locomotion, nutrition, endocrinology, cardiovascular respiratory systems, and homeostasis. You will also be introduced to the diversity of microbial life, vegetation and ecosystems. A series of linked experiments will help you to develop the basic practical skills required for research.

In the second year you will look at the organisms and processes that characterize freshwater and marine ecosystems. You will examine invertebrate zoology, and the theoretical background for understanding the theory of evolution and how modern molecular techniques contribute to its study. You will become acquainted with the principles and practice of a range of basic quantitative and qualitative procedures of data analysis, coupled with an understanding of good research design and planning. Optional modules on environments, ecology and hydrochemistry will enable you to tailor your study to suit your own interests.

In the third year you will study aquatic animal physiology and ecology and will look at invertebrate and vertebrates living within aquatic and terrestrial ecosystems. Residential field courses away from Aberystwyth will enable you to observe a range of organisms found in European waters and gain further experience of field sampling and laboratory analysis. A compulsory dissertation will allow you to perform in-depth research under the guidance of a supervisor. Your project may be based on laboratory experiments or fieldwork exercises, comprise a computer modelling exercise, or involve a critical review of published scientific literature.

Among many skills, you will learn to: synthesize information from scientific literature; understand and explain the implications of developments in subjects such as parasitology; scrutinise data in terms of quality and quantity; and respond to new data through laboratory investigation.

How will I be taught?

The course will be delivered through a balanced programme of lectures, workshops, tutorials, fieldwork and practicals. Some aspects of the course will rely on student-centred e-learning, supported by computer workshops. You will receive thorough training in zoological and biological concepts and practical scientific methods.

You will be assessed through numerous methods including essays, practical exercises, oral presentations, worksheets, reports, statistical exercises, dossiers, posters, portfolios, wikis, reflective diaries, literature reviews, magazine articles, field notebooks and exams.

The University's scientific community and the Department's supportive staff will will greatly assist you in your biological training. You will also benefit from the opportunities within the department and the university to develop your theoretical and practical expertise so that, upon graduation, you are perfectly positioned for the next stage of your career.

You will be assigned a personal tutor throughout your degree course, who will help you with any problems or queries, whether these are academic-related or personal issues. You should feel free to contact them at any time for help and advice.

You will also have the opportunity to complete a Personal Development Plan (PDP) at Aberystwyth. This is a structured process of self-appraisal, reflection, and planning, which will enable you to chart your personal, academic and professional development throughout your time at university. By recording your academic performance, and highlighting the skills you already have and those you will need for future employability, the PDP portfolio will equip you with the necessary tools to plan effectively, develop successful approaches to study, and consider your future career options and aspirations.

Student Views

"I enjoyed my time studying Marine and Freshwater Biology and I am able to now apply various aspects of what I was taught during my three years to my current job role, even though it is not directly related to my course. The practical elements of my course were excellent, especially the two 3rd year field trips." Rebecca – Project officer,  Forestry Commission

"Studying Marine & Freshwater Biology at Aberystwyth makes the course that bit more special. The location is perfect as you have both the sea and inland freshwater systems running through Aberystwyth into the sea. There is an array of diverse organisms right on your door-step at Aberystwyth; combining that with a lot of research in the field and the aquarium facilities makes the whole experience more engaging and enjoyable!" Richard Harris

"With the knowledge and scientific mindset I gain though my studies, I hope to be able to help preserve these fascinating environments for future generations. The course has been great; its main strength is its variety, with an array of topics covered over the three years in increasing detail." George William Middleton

"The course gave me a good grounding in all aspects of marine and freshwater biology. There were plenty of opportunities for fieldwork in the course, including the dissertation project, which prepared me for the survey skills needed in my current job." Laura – Environment Officer Gwynedd County Council

"At the Marine Conservation Society I head the conservation team of 17 individuals working on everything from overfishing and the need for marine reserves to dealing with the growing problem of plastic waste at sea. I'm 37 now and I look back at my time in Aber with real fondness. The study helped, but the most important thing for me was that I developed an interest in the sea. Aber was a truly great place to do that, living on the seafront, and diving with the University sub-aqua club." Simon – Head of Science, Marine Conservation Society

I really enjoyed the course. This made it easier to get up for lectures in the morning! The field courses were a highlight and nothing beats getting out there and getting your hands wet, whether it is doing a kick-sample in a small stream or doing a transect down a rock-pool strewn shoreline.  I really liked the broad scope of the course and the opportunity to tailor the course through the various optional modules in the second and third years. As such it has given me a great grounding in biological science as a whole – essential for a role where you have to consider the whole ecosystem and look at so much more than just the fish and the immediate riverine habitat.  Stuart Manwaring – Fisheries Technical Officer, Environment Agency
