This study sought understand update list most assess some ethnotaxonomic patterns employed by artisanal fishers from Amazon Coast naming elasmobranchs.

As predators, coastal and oceanic sharks play critical roles in shaping ecosystem structure function, but most shark species are highly susceptible to population declines. Effective management of vulnerable populations requires knowledge species-specific movement habitat use patterns. Since often mobile long-lived, tracking their patterns over large spatiotemporal scales is challenging. However...

The decline of shark populations in the world ocean is affecting ecosystem structure and function an unpredictable way new ecological information today needed to better understand role sharks their habitats. In particular, characterization foraging patterns crucial foresee evolution dynamics between prey. Many species use mesopelagic area as a major ground but degree which different pelagic rel...

Given population declines of many shark species, coupled with increasing conservation efforts and recoveries, there is a need for baseline assessments continued monitoring populations to support management. The waters South Florida, USA, are used by diverse array sharks that occur among mosaic habitats management zones. Here we conducted standardized drumline surveys from Miami through the midd...

The burgeoning and largely unregulated trade in shark fins represents one of the most serious threats to shark populations worldwide. In Hong Kong, the world's largest shark fin market, fins are classified by traders into Chinese-name categories on the basis of market value, but the relationship between market category and shark species is unclear preventing identification of species that are t...

Shark take, driven by vast demand for meat and fins, is increasing. We set out to gain insights into the impact of small-scale longline fisheries in Peru. Onboard observers were used to document catch from 145 longline fishing trips (1668 fishing days) originating from Ilo, southern Peru. Fishing effort is divided into two seasons: targeting dolphinfish (Coryphaena hippurus; December to Februar...

The hammerhead shark has high economic value, but its population is highly threatened due to exploitation. This study aims calculate the level of preference fishermen on value willingness pay for conservation resources. research was conducted from November December 2020 in Tanjung Luar Village, East Lombok Regency. method used observation and in-depth interviews with a sample 150 fishermen. ana...
