Interannual Differences for Sea Turtles Bycatch in Spanish Longliners from Western Mediterranean Sea

The Scientific World Journal, 2014
Recent studies showed that regional abundance of loggerhead and leatherback turtles could oscillate interannually according to oceanographic and climatic conditions. The Western Mediterranean is an important fishing area for the Spanish drifting longline

The Ecuadorian Artisanal Fishery for Large Pelagics: Species Composition and Spatio-Temporal Dynamics. [PDF]

PLoS ONE, 2015
The artisanal fisheries of Ecuador operate within one of the most dynamic and productive marine ecosystems of the world. This study investigates the catch composition of the Ecuadorian artisanal fishery for large pelagic fishes, including aspects of its ...

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 ...

Understanding the Interactions Between Cetaceans and Other Megafauna With the Albacore Tuna Fishery: A Case Study From the Cyprus’ Pelagic Longline Fishery

Frontiers in Marine Science, 2022
Depredation by cetaceans on fisheries is a major issue globally, both in terms of conservation and fisheries economics. The present study conducted in Cyprus, Eastern Mediterranean Sea, aimed to understand the extent, level, and type of cetacean ...

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

Contrasting associations between parental coordination and breeding success in albatrosses across differing environmental contexts

Journal of Animal Ecology, EarlyView.
Our study demonstrates that the benefits of parental coordination in albatrosses are context‐dependent rather than universal. Coordinated parental care enhanced reproductive success in stable environments, but had little effect in variable environments, where individual flexibility may be more valuable.

Historical review of the billfish management in the Mexican Pacific

Ciencias Marinas, 1998
Off the Mexican Pacific coast, high catch rates are found for striped marlin, sailfish and swordfish, and to a lesser extent for blue marlin and black marlin, making this area an important fishing ground for commercial and sport-fishing fisheries.

Comparative review of entanglement risk assessments for cetacean conservation and management

Conservation Biology, EarlyView.
Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

Observer coverage and interaction rates determine the choice between design‐based and machine learning bycatch estimators for rare species

Conservation Biology, EarlyView.
Abstract Robust estimates of the magnitude of protected species bycatch are essential for effective fisheries management and marine conservation. Existing bycatch estimation methods typically struggle to accurately and precisely estimate the bycatch of rare species as a result of the statistical assumptions necessary to overcome infrequent encounters ...
