Summary

Fish are dependent on their auditory systems for communication, orientation and evaluation of ‘acoustic daylight’, but could be under threat from rising levels of anthropogenic noise. Boats, ships, construction, resource extraction, and other human activities create underwater noise that could cause tissue damage, auditory threshold shifts, masking and a range of behavioural changes. Fish provide a vital food source to millions of people and form crucial links in many food webs, studying their development and behaviour can give us an insight into population and community level impacts of noise that are relevant to species survival and evolution.

Ships are the most widespread source of chronic noise and during my PhD I will investigate how this affects the vulnerable developmental stages of fish. I plan to test how ship noise affects fluctuating asymmetry (a measure of an animal's ability to deal with environmental stress), growth, responses to natural sounds, auditory thresholds (using auditory evoked potentials), behaviour, and whether different behavioural types are better equiped to deal with noise stress.

I am working under the supervision of Drs. Andy Radford, Marc Holderied and David Lecchini, with Steve Simpson, Julia Purser, Irene Vollmy and Rick Bruintjes. Our research pages can be found here. Part of my work is based in the UK on threatened yet commercially important species such as cod, the other part is based at CRIOBE in French Polynesia on a variety of species inhabiting fragile coral reef ecosystems.
