Assessing fishery interaction on cetaceans stranded along the Italian coastline between 1986 and 2023. [PDF]
PLoS ONEMonitoring stranded cetaceans represents a strategic method to assess their health, conservation status, and ecological role in the marine ecosystem. Efficient stranding networks and standardized protocols are essential to monitor this phenomenon and ...

Management of gillnet fisheries in the south coast of the state of São Paulo, Brazil [PDF]
Anais da Academia Brasileira de Ciências, 2014 Gillnetting is one of the most practiced fishing methods adopted in the South of Brazil and has been increasingly expanding over the last years. This paper presents the characterization of the activity and discusses its management, in accordance to ...

Gillnet selectivity for the north African catfish, Clarias gariepinus (Actinopterygii: Siluriformes: Clariidae), from the Upper Okavango Delta, Botswana [PDF]
Acta Ichthyologica et Piscatoria, 2015 Background. Successful fisheries management requires estimation of gillnet selectivity for optimum exploitation of the resource. In the Okavango Delta, no study has assessed the selectivity of gillnets for Clarias gariepinus (Burchell, 1822) which is an ...

Disentangling the causes of protected‐species bycatch in gillnet fisheries [PDF]
Conservation Biology, 2017 Abstract Gillnet fisheries are widely thought to pose a conservation threat to many populations of marine mammals, seabirds, and turtles. Gillnet fisheries also support a significant proportion of small‐scale fishing communities worldwide. Despite a large number of studies on protected‐species bycatch in recent decades, relatively few

Artisanal fishery with surface gillnets and megafauna strandings
Sociedade & Natureza, 2023 Bycatch is an issue of worldwide relevance involving conflicts between conservation and fishery interests. In Brazil, this conflict has been highlighted in relation to the regulation of small-scale fishery with surface gillnets. To promote management and transformation of this conflict, we analyzed the relationship between catch unloadings from small ...

Selection due to nonretention mortality in gillnet fisheries for salmon [PDF]
Evolutionary Applications, 2010 AbstractFisheries often exert selective pressures through elevated mortality on a nonrandom component of exploited stocks. Selective removal of individuals will alter the composition of a given population, with potential consequences for its size structure, stability and evolution. Gillnets are known to harvest fish according to size.

Utilization of A Bioluminescent Pattern in the Encircling Gillnet Fisheries
Reviews in Fisheries Science, 2010 To investigate the relationship between bioluminescent patterns and targeted fish species that cause this pattern, encircling gillnet sampling was conducted in shallow water (< 12 m) on moonless nights between February 2007 and December 2008 in the northern Aegean Sea, Turkey.
