The elasmobranch population is declining in the Bay of Bengal of Bangladesh due to large-
mesh gill net fishing, locally known as the Lakkha net, which primarily targets Indian …

The diversity of freshwater obligate and euryhaline generalist chondrichthyans is low, yet
they offer a unique insight into elasmobranchs adapted to non-marine environments. The …

Tropical fisheries tend to be multispecies and require management approaches adapted to
high diversity but scarce and poorly informative data. Productivity and Susceptibility Analysis …

High fishing pressure on elasmobranchs had caused declines in their populations
worldwide, though these declines may not always be observed due to lack of monitoring …

Here, we use vertebral microchemistry to investigate the habitat use patterns of the longnose
stingray Hypanus guttatus in the northern and northeastern regions of Brazil, and to evaluate …

Demand for ray consumption has been increasing considerably along coastal areas of the
Western Atlantic Ocean, especially Northeast Brazil. Species previously caught as bycatch …
