“…Awareness of the effect of noise on aquatic life has brought a renewed urgency to the study of acoustics and soundscape ecology (Markus & Sánchez, ). In coastal embayments that surround ports and harbours the ambient sound level is estimated to double in intensity every decade (Hatch & Wright, ; Merchant et al ., ).…”

“…In coastal embayments that surround ports and harbours the ambient sound level is estimated to double in intensity every decade (Hatch & Wright, ; Merchant et al ., ). Increased shipping into coastal ports (Boyd et al ., ; Frisk, ) and shorter port turnaround times (Markus & Sánchez, ) means decreasing the time between vessel transits and more time on the water, thereby increasing noise exposure time for resident aquatic life. Voluntary regulations are being enforced in some countries to control underwater noise pollution.…”

“…To date, no binding regulations on ship noise have been made within the International Maritime Organization's (IMO) framework. Nevertheless, the IMO's Marine Environment Protection Committee has paid attention to the topic and approved the non‐mandatory guidelines (IMO, ; Markus & Sánchez, ). However, noise, unlike more persistent forms of pollution, ceases to exist once the source is removed, so management measures have the potential to produce rapid improvements in habitat quality.…”

“…One of the biggest challenges faced by those charged with monitoring ecosystems is decision making in the absence of essential information. Even when studies have been conducted, the nature and effects of underwater noise are often strongly dependent on the specific circumstances of the ecosystem in which the study was conducted (Markus & Sánchez, ). The area over which anthropogenic noise may adversely affect aquatic species depends upon multiple factors including the extent of sound propagation, its frequency characteristics and duration, its distribution relative to the location of organisms and the absolute sensitivity and range of spectral hearing among species.…”

Underwater sound is directional and can convey important information about the surrounding environment or the animal emitting the sound. Therefore, sound is a major sensory channel for fishes and plays a key role in many life‐history strategies. The effect of anthropogenic noise on aquatic life, which may be causing homogenisation or fragmentation of biologically important signals underwater is of growing concern. In this review we discuss the role sound plays in the ecology of fishes, basic anatomical and physiological adaptations for sound reception and production, the effects of anthropogenic noise and how fishes may be coping to changes in their environment, to put the ecology of fish hearing into the context of the modern underwater soundscape.

“…In contrast with the flourishing literature and number of mitigation actions for the aforementioned noise sources, very little attention has been paid to addressing noise produced by ports in their surroundings. Most of the scientific studies about noise generated from vessels concern onboard noise [29][30][31] or interference with animal life [32][33][34] and oceanic ambient noise [35,36], since, currently, noise produced underwater is more studied than airborne noise [37][38][39][40]. Overall underwater ship-radiated noise is the sum of propulsion noise, propeller noise, auxiliary noise, and hydrodynamic noise [41], with eventual tonal components caused by the propeller and associated cavitation noise [42].…”

After the European Environmental Noise Directive prescribed noise maps and action plans, wide scientific literature and a consistent number of mitigation strategies emerged for road, railway, airport, and industrial noise. Unfortunately, very little attention has been paid to the noise produced by ports in their surroundings, even though there could be many areas affected by it. At present, more attention seems to be paid to noise produced underwater, mostly for military and security reasons and for its interference with wildlife, rather than airborne noise and its influence on human health. In the framework of a project aiming to shed more light on a topic so far under-investigated, this paper presents an acoustical characterization of different small vessels at various speeds that move around on a daily basis in every type of port, produced by means of short- and long-term measurements. The new information acquired was used to produce a map of noise generated by vessels moving in Livorno’s canals, which branch off in a densely inhabited area. The simulations were validated using long-term measurement. The number of citizens exposed was also estimated and used to calculate the number of highly annoyed people according to the recent curve for road traffic noise proposed by Guski et al. In order to prevent citizen exposure to noise and possible complaints about small boats, different scenarios and possible future situations such as various vessel speeds, limited flow, restricted areas for some categories, or new residential areas were studied.

Ecotourism impacts on reef fishes in a marine reserve during the COVID‐19 era

Marine reserves generally permit ecotourism within their boundaries as a source of income for local communities, but the impacts of ecotourism on wildlife are still poorly understood. The lockdown resulting from the COVID‐19 pandemic in 2020 provided a unique opportunity to evaluate wildlife diversity in the absence of human activity. In a marine reserve in Mexico, we monitored fish assemblages before, during, and immediately after the lockdown to examine ecotourism impacts on fish assemblages. Our results show that fish density rose 2.5‐fold during the lockdown, suggesting that ecotourism activities alter fish behavior. We suggest that the presence of divers and noise pollution generated by recreational vessels are important disturbance factors. In the absence of human activity, however, some fish may be more bold (hide less often) or may return to the reserve after having retreated to more tranquil (deepwater) areas. We hope that our findings spur efforts to improve the health of marine reserves through the establishment of effective management strategies to mitigate ecotourism impacts.
