Effects of man-made noise on fish development and behaviour

Fishes and many invertebrates 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 can cause tissue damage, auditory threshold shifts, masking, and a range of physiological, cognitive and behavioural changes. Fishes and invertebrates provide a vital food source to millions of people and form crucial links in many food webs, investigating the fitness consequences of noise pollution will lend insights to the population and community level impacts of noise that are relevant to species survival and evolution.

I am interested in how animals sense and process information about the world around them, and how this influences physiology, behaviour, communication and intergenerational effects.
