Digel, Patrick Zubick, Grant Johnson, Michael Usher, Nicholas K. Dulvy ABSTRACT: Fisheries management is essential to guarantee sustainable capture of target species and avoid undesirable declines of incidentally captured species. A

Everett, Andrew J. Temple, Jeremy J. Kiszka, Edward Kimani, Per Berggren ABSTRACT: Shark catches are common in small-scale (artisanal) and recreational fisheries; the magnitudes of these catches remain

Unintended effects of single-species fisheries management
Unintended effects of single-species fisheries management Mariana Tolotti, Patrice Guillotreau, Fabien Forget, Manuela Capello, Laurent Dagorn ABSTRACT: Ecosystem-based management is widely recognized as the path to achieve sustainability of ecosystem services. Tuna Fisheries Management Organizations have incorporated an ecosystem approach into their mandate, but their decision-making process essentially relies on individual stock assessments. This study

Grouping behaviour impacts on the parasitic pressure and squamation of sharks
Grouping behaviour impacts on the parasitic pressure and squamation of sharks Humberto G. Ferrón and Jose F. Palacios-Abella ABSTRACT: The evolution of grouping behaviour involves a complex trade-off of benefits and costs. Among the latter, an increase in the risk of parasitic transmission is a well-documented phenomenon that has likely promoted the evolution of defensive
