Full-text available
Marine tourism is promoted as a substitute economic activity to unsustainable fishing, which is compatible with conservation. However, benefits of marine tourism do not typically accrue in small-scale fisheries (SSFs), which often bear the costs of conservation; they accrue to tourists and tourist-focussed businesses. We explored how marine tourism...

Permit (Trachinotus falcatus) occupy a variety of coastal marine habitats and support valuable recreational fisheries in their home region of the Caribbean Sea. As an aggregate spawning species, Permit require careful management in locations such as the Florida Keys where they experience substantial fishing pressure. We used acoustic telemetry to e...

It is well known that a strong fisheries industry, with much funding for such research and many national universities include a Faculty of Fisheries. Thus, there may be a general bias in research and instruction towards fisheries-related species, possibly at the expense of other marine biodiversity research and taxa. More capacity building and inve...

Vessel traffic is one of the major sources of underwater anthropogenic noise. Dolphins can modify their vocal repertoire, especially whistles, in presence of vessels to facilitate their communication. Acoustic data were collected (sampling rate 96 kHz) in La Paz Bay, Gulf of California, Mexico. Whistle rate and parameters of the coastal and oceanic...

Obtaining dispersal estimates for a species is key to understanding local adaptation and population dynamics, and to implementing conservation actions. Genetic isolation‐by‐distance patterns can be used for estimating dispersal, and these patterns are especially useful for marine species in which few other methods are available. In this study, we g...

Abstract: Estimating cetacean interactions with fishery activities is challenging (Kuiken, 1996; Moore et al., 2013). Bycatch is responsible for thousands of cetacean deaths per year globally (Young & Iudicello, 2007; Dolman & Moore, 2017). This study updates the data on fishery interaction in stranded cetaceans in the Canary Islands, from the last...
