FISHNOISE

Research on the Impact of anthropogenic noise on fish fitness

 

This project aims to evaluate the impact of a chronic and pervasive source of man-made noise on direct measures of fitness in model fish species

 

WHY

Marine traffic is the most common and chronic source of ocean noise pollution. Recent studies point to detrimental effects on fish but the assessment of impacts on individual fitness and resulting changes at the population level are needed to consider mitigation and management measures

MODELS

This proposal will evaluate the effect of boat noise on reproductive success, early-life development and survival in two vocal fishes, the meagre (Argyrossomus regius) and the Lusitanian toadfish (Halobatrachus didactylus).

HOW

Field and lab experiments using a multimethod approach (passive acoustic recordings, playback experiments, telemetry and evaluation of stress response biomarkers) will yield ecological relevant results necessary to provide guidelines to regulators.

 

Key concepts

Noise pollution

Man-made noise can affect animal behaviour and physiology and is now acknowledged as a chronic source of pollution that is changing underwater soundscapes.

Fish sounds

Several species produce sounds in contexts such as courtship, or spawning and may rely on acoustic communication for successful breeding. These sounds can be used to monitor each species.

Soundscape characterization

The combination of natural (biotic and abiotic) and anthropogenic sounds form the soundscape of environment. Through passive acoustic monitoring we can extract information to infer biodiversity and environmental quality.

Masking

Fish use sound to interpret their surroundings, including conspecifics, predator and prey detection, but noise can reduce its hearing ability.
