HAMMER: a tool to predict the impact of man-made noise on fishes

Fish and Noise: Why should we care?

All fish sense sounds and use natural
soundscapes (e.g. for finding food, choosing
mates, orientation and predator avoidance).

Fish can be impacted by noise (see next box).

Fish underpin many marine food webs.

Many fish species are commercially important
and provide food security for millions of people.

Several fish species are protected or are of
conservation concern (e.g. salmon and eels).

Underwater noise is included in national and
international legislation (e.g. EC 2008; DEFRA 2009).
