Offshore wind energy development: Research priorities for sound and vibration effects on fishes and aquatic invertebrates

The Journal of the Acoustical Society of America, Год журнала: 2022, Номер 151(1), С. 205 - 215

There are substantial knowledge gaps regarding both the bioacoustics and responses of animals to sounds associated with pre-construction, construction, operations offshore wind (OSW) energy development. A workgroup 2020 State Science Workshop on Wildlife Offshore Wind Energy identified studies for next five years help stakeholders better understand potential cumulative biological impacts sound vibration fishes aquatic invertebrates as OSW industry develops. The seven short-term priorities that include a mix primary research coordination efforts. Key needs examination animal displacement other behavioral sound, well hearing sensitivity related particle motion, substrate vibration, pressure. Other include: identification priority taxa which focus research; standardization methods; development long-term highly instrumented field site; mitigation options invertebrates. Effective assessment is currently precluded by these gaps. However, filling critical in will improve our understanding possible sound-related populations ecosystems.

How to set sound exposure criteria for fishes

The Journal of the Acoustical Society of America, Год журнала: 2020, Номер 147(3), С. 1762 - 1777

Underwater sounds from human sources can have detrimental effects upon aquatic animals, including fishes. Thus, it is important to establish sound exposure criteria for fishes, setting out those levels of different that them, in order support current and future protective regulations. This paper considers the gaps information must be resolved reasonable The vulnerability fishes affected by characteristics underwater sounds, which taken into account when evaluating effects. need considered include death injuries, physiological effects, changes behavior. Strong emphasis assessing has been placed hearing abilities However, although account, other actual also considered. filled development guidelines criteria.

Fish hearing and how it is best determined

ICES Journal of Marine Science, Год журнала: 2021, Номер 78(7), С. 2325 - 2336

Abstract Hearing, as defined by numerous investigators of vertebrate hearing, involves not only detection a sound, but the ability to respond sound behaviourally. Thus, in order understand what fish (or any animal) hears, it is important use behavioural methods that allow an animal “tell investigator” which sounds are detected and not. However, since 1980’s, most studies suggest they measuring hearing have used electrophysiological approaches measure response ear or lower levels central auditory system sounds. In this paper, we argue these measures do represent indicate can potentially while provide some useful interesting insights into mechanisms, valid sensitivity, understanding (anthropogenic otherwise) able to, obtained using studies. We also must be done carefully designed acoustic setups so nature stimulus responds appropriate well understood.

Recommendations on bioacoustical metrics relevant for regulating exposure to anthropogenic underwater sound

The Journal of the Acoustical Society of America, Год журнала: 2024, Номер 156(4), С. 2508 - 2526

Metrics to be used in noise impact assessment must integrate the physical acoustic characteristics of sound field with relevant biology animals. Several metrics have been established determine and regulate underwater exposure aquatic fauna. However, recent advances understanding cause-effect relationships indicate that additional are needed fully describe quantify fields on Existing regulations primarily focused marine mammals based dichotomy types as being either impulsive or non-impulsive. This classification types, however, is overly simplistic insufficient for adequate assessments It recommended definition impulsiveness refined by incorporating kurtosis an parameter applying appropriate conversion factor. Auditory frequency weighting functions, which scale importance particular frequencies account animal's sensitivity those frequencies, should applied. Minimum phase filters calculating weighted pressure. Temporal observation windows reported signal duration influences its detectability Acknowledging auditory integration time differs across species dependent, standardized temporal proposed various types.

Ocean acidification effects on fish hearing

Humans are rapidly changing the marine environment through a multitude of effects, including increased greenhouse gas emissions resulting in warmer and acidified oceans. Elevated CO 2 conditions can cause sensory deficits altered behaviours organisms, either directly by affecting end organ sensitivity or due to likely alterations brain chemistry. Previous studies show that auditory-associated larval juvenile fishes be affected elevated (1000 µatm). Here, using auditory evoked potentials (AEP) micro-computer tomography (microCT) we raising snapper, Chrysophyrs auratus , under predicted future resulted significant changes their hearing ability. Specifically, snapper raised had decrease low frequency (less than 200 Hz) sensitivity. MicroCT demonstrated these sacculus otolith's were significantly larger fluctuating asymmetry, which explains difference We suggest have dual effect on hearing, effecting organs altering previously described induced behaviours. This is first time been empirically linked modification anatomy fish Given widespread well-documented impact anatomy, predictions how life-history functions dependent may respond climate change need reassessed.
