Fisheries depredation by marine mammals is an economic concern worldwide. We combined questionnaires, acoustic monitoring, and participatory experiments to investigate the occurrence of bottlenose dolphins in the fisheries of Northern Cyprus, and the extent of their conflict with set-nets, an economically important metier of Mediterranean fisheries. Dolphins were present in fishing grounds throughout the year and were detected at 28% of sets. Net damage was on average six times greater where dolphins were present, was correlated with dolphin presence, and the associated costs were considerable. An acoustic deterrent pinger was tested, but had no significant effect although more powerful pingers could have greater impact. However, our findings indicate that effective management of fish stocks is urgently required to address the overexploitation that is likely driving depredation behaviour in dolphins, that in turn leads to net damage and the associated costs to the fisheries.Electronic supplementary materialThe online version of this article (10.1007/s10745-018-9989-7) contains supplementary material, which is available to authorized users.

“…Examples of deliberate human use of marine sound include seismic surveys that produce high-energy, low-frequency, shortduration sounds aimed at detecting the presence of petroleum and gas deposits below the seafloor, as well as multibeam echosounders and side-scan sonars that generally produce high-frequency sounds to map the seabed and detect organisms and particles in the water column. These sensing techniques are, at times, a major component of present ocean soundscapes in many areas, especially those holding oil and gas reservoirs (49,50), such as the continental shelf of northwestern Australia and the North Sea (Fig. 3D).…”

Oceans have become substantially noisier since the Industrial Revolution. Shipping, resource exploration, and infrastructure development have increased the anthrophony (sounds generated by human activities), whereas the biophony (sounds of biological origin) has been reduced by hunting, fishing, and habitat degradation. Climate change is affecting geophony (abiotic, natural sounds). Existing evidence shows that anthrophony affects marine animals at multiple levels, including their behavior, physiology, and, in extreme cases, survival. This should prompt management actions to deploy existing solutions to reduce noise levels in the ocean, thereby allowing marine animals to reestablish their use of ocean sound as a central ecological trait in a healthy ocean.

“…Ocean noise pollution is increasingly being understood as a problem that not only directly injures whales in close proximity to sound sources, but also degrades their habitat over widespread regions with potential for population level impacts (Francis & Barber 2013). Average ambient noise levels at low frequencies in the northern GoM are among the highest measured in the world's oceans, and seismic airgun surveys for energy exploration and shipping traffic dominate these high noise levels (Estabrook et al 2016, Wiggins et al 2016. Notably, the primary GoM Bryde's whale habitat near the De Soto Canyon is quieter than other sites in the northern GoM due to lower levels of shipping and seismic survey activity (Estabrook et al 2016, Wiggins et al 2016), but noise levels are still high compared to current and historical levels in other baleen whale habitats in US waters (e.g.…”

Bryde's whales Balaenoptera edeni are the only resident baleen whale species in the Gulf of Mexico (GoM), where they are extremely rare, have a restricted distribution, and represent a unique evolutionary lineage. The reasons for the restricted distribution and small population size are unknown, but high levels of industrial activity in the GoM may be a major factor. We evaluated the geospatial overlap of GoM Bryde's whales with 2 industries known to impact baleen whale species: commercial shipping and commercial fisheries. We further evaluated the potential for impacts by examining the first dive behavior data collected from a kinematic tag attached to a GoM Bryde's whale for 3 d. Vessel traffic and fishery effort are low in GoM Bryde's whale habitat compared to the rest of the northern GoM, but several shipping lanes transit through the habitat, and the reef fish bottom longline fishery exerts considerable effort within the habitat. The tagged whale exhibited diel diving behavior with diurnal deep dives and foraging lunges at or near the sea floor, and shallow nocturnal diving, with 88% of its nighttime spent near the surface within the draught depths of most large commercial vessels. Given the location of commercial shipping traffic in GoM Bryde's whale habitat, ship strikes may pose a threat to this population if the whales commonly spend time near the surface, especially at night. Also, if bottom or near-bottom feeding is a normal feeding strategy for these whales, there is potential for entanglement in bottom longline gear. Managing these threats may improve population recovery.
