Asa White, Doctoral Researcher within our school, gets to call wading around in the Bourne Rivulet work!
Asa’s is researching how an invisible chemical may be affecting invertebrate and fish life. It has three main elements.
- using electric fishing surveys around three watercress farms over two years to ascertain whether discharges are having a population-level impact on fish communities
- at the same sites, surveying habitat suitability for salmonids in terms of the physical habitat and prey species abundances
- running laboratory ecotoxicology experiments to study the effects of PEITC on fish. The aim of the research is to understand what effect, if any, watercress farming is having on fish populations. Should a negative impact be uncovered, then mitigation strategies to lessen the impacts could be developed to ensure that fish populations in chalk stream headwaters flourish.
