Our multi-disciplinary scientists & biologists undertake in-depth desk & field surveys to deliver a range of scientific services, including ecological impact assessment throughout the UK and Europe.
THA Aquatic’s field expertise is underpinned by stringent Health & Safety values. Our personnel are not only First Aid trained but also hold additional qualifications in Sea Survival, Power Boating and Electric-fishing. 

Supported by the most appropriate methodologies and field equipment, we are well resourced to undertake large or small-scale ecological survey projects, following all necessary procedures & protocols determined by the Appropriate Authority.
Our in-house biostatistics & mathematical modelling specialists analyse resulting survey data and present it in a format best suited to the recipient.
