摘要

Sensory cues are important in the regulation of embryonic development and hatching for many marine invertebrate species, allowing an embryo to detect and respond to changes in the external environment. Multiple stressors, such as increased substrate-borne vibration and changes in water chemistry from anthropogenic activities, could therefore influence hatching times and disrupt developmental processes. This review briefly summarises current research regarding the impacts of anthropogenic noise on the embryonic development and hatching of marine invertebrates, being most relevant to this proceedings volume. A limited number of studies have found impacts ranging from decreased hatching success to altered developmental rates. Although substrate-borne vibration is a major component of anthropogenic noise in marine environments, there are no published studies on embryonic development and hatching to date, both in a single and multi-stressor context. Investigating embryonic and larval stages of species is crucial to develop a population level understanding of how multiple stressors potentially impact marine invertebrates and therefore marine ecosystems. Results will be informative for conservation management, impact assessments, policy development, and mitigation measures for anthropogenic activities relating to the seabed.
