CHONe Project: 2.1.4: Anthropogenic noise in the ocean soundscape: Effects on fishes and invertebrates.
Project Title: Underwater sound effect on larval behaviour, development and settlement of invertebrate species associated with biofouling.
The aim of this project is to assess the underwater anthropogenic sound effect on larval behaviour, development and settlement of invertebrate species associated with biofouling. Three intensity levels of pile driving, drilling and boat sound will be tested in aquariums on larval stages of two bivalve species (blue mussel and American oyster), one barnacle and tunicate species, and two benthic diatoms species. Emphasis is placed on larval development and settlement success under sound treatments. Overall, this study will help to understand larval and algae response to different sound and effect according to the source’s distance.
The specific project/thesis aims are:
- Measure larval settlement success under sound treatments
- Compare foraging (clearance rate) and larval development between sound treatments
- Evaluate the biofilm development
- Develop a new experimental design for acoustic studies
- Feed data for the development of quantitative models
