Analysis of the fishing effort of the Mexican longline tuna fleet operating in the Gulf of Mexico in 2004

Ciencias Marinas, 2010
The Gulf of Mexico yellowfin tuna (YFT) longline fishing effort for 2004 was analyzed. The data used to describe the longline characteristics and estimate the catch efficiency of the vessels (catch in number of organisms per trip) were obtained from ...

Interactions Between a Large Marine Protected Area, Pelagic Tuna and Associated Fisheries

Frontiers in Marine Science, 2020
The efficacy of large marine protected areas (MPA) for the conservation of mobile pelagic species is widely debated. Here, we quantified spatial and temporal trends in standardized catch per unit effort (CPUE) of two target pelagic species, yellowfin ...

Study on the catch, bycatch and discard of Chinese pelagic longline fisheries in the Atlantic Ocean

Aquaculture and Fisheries
Catch, bycatch and discard information is important for the assessment and management of fisheries. Using Chinese pelagic tuna longline observer data from 2010 to 2018, we studied the catch composition in the Chinese pelagic tuna longline fisheries in ...

Depth and season‐related variability in fatty acid composition and lipid nutritional quality indices of farmed Mytilus galloprovincialis

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Lipid quality is one of the most important indicators of the nutritional value of farmed mussels. In open‐coastal environments, factors such as cultivation depth and seasonal changes affect lipid dynamics, but their combined effects on lipid quality remain unclear.

Comparative analysis of depth distribution for seventeen large pelagic fish species captured in a longline fishery in the central-eastern Pacific Ocean

Scientia Marina, 2012
The objective of this study was to estimate depth distribution of pelagic species captured in a longline fishery and to evaluate the difference in depth distribution among species.

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

Conservation Biology, EarlyView.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

Conservation Biology, EarlyView.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.
