Trouble at Sea: Data and digital technology challenges for maritime human rights concerns

Recent years have revealed the severity and scale of human rights abuses at sea. Yet maritime investigations remain challenging due to an array difficulties, including physical inaccessibility a complex legal environment. Improving availability data has been framed as solution that will enhance transparency in marine-related activities improve accountability for violations. Such enthusiasm fuelled development technological solutions promising identify safeguard vulnerable individuals. However, these efforts clash with concerns over use technology practice.

Temporal and spatial variations in squid jigging catch efficiency in the Oyashio Extension region

Fisheries Oceanography, Journal Year: 2024, Volume and Issue: 33(6)

Published: July 17, 2024

Abstract The abundance of fishery resources significantly impacts the ratio fishing effort to harvest. However, traditional statistics catches or commonly used catch per unit (CPUE) metrics cannot accurately capture complexity resource in ocean. To address this issue, we propose here a novel approach that integrates actual from vessel logs with duration obtained through automatic identification system (AIS) positioning. This combined analysis eliminates confounding factors and introduces metric called “catch efficiency (CE)” evaluate operations more accurately, thereby reflecting reasonable way. In study, focus on CE squid Oyashio Extension region Northwestern Pacific. Our reveals significant temporal spatial variations CE, manifesting both intensity distribution patterns. Moreover, our findings establish close relationship between background water mass distribution, chlorophyll‐a concentration, micronekton biomass. implies can be inferred by considering varying environmental within area.

Opportunity to Leverage Tactics Used by Skilled Fishers to Address Persistent Bycatch Challenges

Fish and Fisheries, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 11, 2024

ABSTRACT Effective management of shark bycatch is urgently needed to reverse widespread population declines, especially in longline fisheries that are estimated be responsible for half global catch. Management catch typically focuses on the safe release landed sharks, with limited attention reducing initial Where controls fishing effort or do exist, frameworks tend treat fleets as homogeneous units. The underlying assumption fishers have similar abilities target species and avoid bycatch. We test this by analysing variability rates among individual vessels an industrial tuna fleet operating Western Pacific. Controlling factors such geographic location, time day gear depth, we find drive highly variable blue ( Prionace glauca ) silky sharks Carcharhinus falciformis – two highest volumes. Additionally, found company can influence fisher performance. As countries regional organisations increasingly adopt conservation plans make international commitments, it crucial identify viable new strategies not unduly burden industry penalise good actors. Tailoring actions companies holding high‐bycatch accountable incentivising low‐bycatch continuously improve presents a opportunity address overfishing other challenges.

Large Pelagic Fish Exploitation by Longliners in the Atlantic Ocean: A Contribution to Spatial Planning and Sustainable Fisheries

Understanding longline fisheries dynamics is crucial for sustainable resource management. This study aims to provide a panorama of the fishing effort principal nations that have exploited tuna and associated species in Atlantic Ocean past decade, integrating vessel data from Global Fishing Watch (GFW) catch International Commission Conservation Tunas (ICAAT), with specific information on production these different fleets resources. Twelve represented 94.6% all Apparent hours (AFH) total 99.9% catches last years. Our revealed regions proximate continental shelf break oceanic islands exhibit notably higher than other areas within Ocean. We also highlight declining trend efforts ten years, likely due regulation overfishing. The blue shark (Prionace glauca) was most caught biomass, representing 38.1%; Big-eye (Thunnus obesus) 20.5%; swordfish (Xiphias gladius) 15.1%; albacore alalunga) 11.3% yellowfin albacares) 6.1%. alarming trends pelagic emphasise need immediate conservation actions. Management strategies should target critical nations, addressing their significant contributions catch. lack several periods highlights comprehensive research management initiatives.
