Overview
Research indicates that coral reef fish exposed to motorboat noise exhibit impaired growth and reduced ability to evade predators. The study focused on the spiny chromis, a species native to the Great Barrier Reef, examining the effects of acoustic exposure during critical developmental stages.
Approach
Scientists conducted an experiment involving spiny chromis (a species from the Great Barrier Reef). The experimental design involved exposing these fish to two distinct acoustic conditions: motorboat noise or natural reef sounds. This exposure occurred during two specific developmental phases: as embryos and shortly after hatching.
Findings
- Coral reef fish subjected to motorboat noise grew to be smaller in size.
- The capacity of these fish to escape predators was negatively affected by motorboat noise exposure.
- These impairments were observed when the spiny chromis were exposed to motorboat noise both during their embryonic stage and immediately following hatching.
