Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters

Global Change Biology, Volume 32, Issue 8, August 2026.
Polar sharks, rays, and chimaeras face growing pressures from changing sea‐ice conditions, expanding fisheries, and limited protection. Our assessment highlights where critical habitats occur and how Important Shark and Ray Areas (ISRAs) can support more targeted conservation and fisheries management across the Arctic and Antarctic.

Simulation modeling of the Adjustable Buoyancy Device for open ocean low trophic aquaculture, part I: Test of a submersible long tube unit

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Open‐water low‐trophic aquaculture (LTA) is a sustainable method for producing ocean‐based food and providing ecosystem services. An effective system design is critical for mitigating risks posed by deep ocean forces. Developing submersible cultivation technology requires quantitative risk analysis and modeling to address offshore challenges ...

Post-release survival of loggerhead sea turtles (Caretta caretta) incidentally hooked in a North Atlantic pelagic longline fishery

Frontiers in Marine Science
Estimating mortality of sea turtles incidentally captured in fishing gear is essential to understanding fishery impacts on sea turtle populations. Loggerhead turtles (Caretta caretta) are a component of bycatch in pelagic longline fisheries, including ...

Seabird bycatch mitigation trials in artisanal demersal longliners of the Western Mediterranean.

PLoS ONE, 2018
High numbers of seabirds are killed annually worldwide in longline fisheries. In the Mediterranean, this mortality is seriously affecting the viability of seabird populations, in particular of the three endemic shearwaters. Even so, there is currently no

Evidence of hook competition in longline surveys

, 2008
Catch rates from surveys are used as indices of abundance for many fish species. Relative abundance estimates from surveys with longline gear do not usually account for possible effects of gear saturation, which potentially creates competition among fish for baited hooks and misrepresentations of abundance trends. We examined correlations between catch

Studies on the Depth of Longline Hook

Studies on the Depth of Longline Hook
The tuna fishing experiments were carried out in the southern region of the Hawaiian Islands in May 1985. Some informations were obtained on the relation between the calculated catenary value and the actual survey value of the depths of hooks of tuna long line and were discussed in comparison with the results of study in 1984.

Deepwater Trawl and Longline Surveys in 1995

, 1997
Two surveys were carried out in 1995 as part of the continuing deep water fish research programme at the Fisheries Research Centre. The trawl survey fished areas on the eastern slopes of the Rockall Trough and on two seamounts of the mid-Atlantic ridge approximately 300 miles north of the Azores.
