Performance of sorting grids on catching elasmobranchs in a multispecies Mediterranean bottom trawl fishery

Submitted by allykristan on

This study investigated the use of two new elasmobranch bycatch reducing devices in a Mediterranean multispecies bottom trawl fishery- the shark excluder device (SED) and a flexible grid (Flexgrid). The SED was effective in reducing elasmobranch bycatch and did not impact mantis shrimp (Squilla mantis) target catch, but did reduce catch for some large bony fish species. The results from the Flexgrid were limited due to small sample size, but there was no impact on catch of main target species although a shark was incidentally caught.

Evaluating the effectiveness of seabird bycatch mitigation measures for pelagic longlines in the South Atlantic

Submitted by allykristan on

This paper focuses on mitigation measures specified by the International Commission for the Conservation of Atlantic Tunas (ICCAT) related to threatened seabirds foraging in the south Atlantic Ocean. The authors developed an ecological risk assessment for various combinations of mitigation measures to protect five threatened albatross and petrel populations, comparing those specified by ICCAT to those recommend by the Seabird Bycatch Working Group of the Agreement on the Conservation of Albatrosses and Petrels (ACAP).

Retention Bans Are Beneficial but Insufficient to Stop Shark Overfishing

Submitted by allykristan on

This study investigated the effectiveness of retention bans for reducing shark mortality in longline and gillnet fisheries, as reported in 160 relevant studies across 341 shark species. Results suggest that retention bans can reduce shark mortality when averaged across all species, but that species with lower intrinsic population growth rates benefit less from a retention ban than those with higher rates of population growth.

The Vanishing Vaquita: A Call for Definitive Action

Submitted by allykristan on

This review paper reflects on the past 50 years of efforts to save the vaquita (Phocoena sinus) from extinction, with the primary threat being lethal bycatch in gillnets set for the totoaba fish in the upper Gulf of California. Both the conservation goals for the vaquita and the economic and social goals for the local fisheries have consistently failed to meet even the lowest stakeholder expectations, and the vaquita population has continued to decline.
