Fisheries Specialist

About the role

We’re looking for a proactive and technically skilled Fisheries Specialist to join South East Rivers Trust (SERT) and help deliver an ambitious programme to improve fish passage and river connectivity across the Great Stour catchment.

This is a unique opportunity to play a central role in progressing the Stour fish passage roadmap, helping to shape a flagship programme that combines monitoring, evidence, partnership working and practical river restoration. Approximately half of your time will focus on the Great Stour catchment, with the remainder spent acting as SERT’s fisheries ecology and management specialist, providing technical leadership and support to colleagues and partners across our wider operational area.

What you will be doing

• Leading fish surveys, monitoring programmes and evidence collection to improve understanding of fish populations, evaluate the impact of our work and inform future restoration priorities.
• Working with colleagues and partners to progress the Stour fish passage roadmap, identifying and prioritising barriers to fish movement and supporting the development of fish passage and river restoration projects.
• Working with landholders, angling interests, regulators and catchment partners to deliver coordinated, catchment-scale action.
• Contributing to business cases, funding proposals and the development of a pipeline of deliverable and investable projects.
• Acting as the Trust’s fisheries ecology and management specialist, providing technical leadership and support to colleagues and partners across SERT.

About you

• Experience in freshwater ecology, fisheries, river restoration or a related discipline, with a good understanding of fish ecology, fish passage and river habitats.
• Experience applying fish survey and monitoring techniques, such as electrofishing, eDNA and habitat surveys.
• Strong analytical skills, with the ability to interpret ecological data and apply it to project development and delivery.
• Experience delivering environmental or river restoration projects and working collaboratively with regulators, landholders, angling interests and other partners.
• Strong communication and relationship-building skills, with the ability to convey technical information clearly.
• A proactive and organised approach, with the ability to manage multiple priorities and work both independently and as part of a multidisciplinary team.

Why work with us?

You’ll be joining a supportive, values-led organisation where your work really matters. We offer flexible hybrid working, opportunities to develop specialist expertise in fisheries ecology, monitoring and river restoration within a growing and ambitious organisation, and the chance to shape a flagship fish passage programme while making a lasting impact for rivers and wildlife.
