The Unseen Crisis of Sharks and Rays in Senegal
This study presents a conservative quantitative assessment of shark and ray landings and trade in Senegal, revealing extensive exploitation of threatened species. Surveys at two major artisanal processing sites in the Casamance region recorded over 170,000 individuals, mostly rays, with nearly all biomass comprising species at risk of extinction, and ...

Age and growth of the bigeye thresher shark,Alopias superciliosus, from the pelagic longline fisheries in the tropical northeastern Atlantic Ocean, determined by vertebral band counts [PDF]
The bigeye thresher, Alopias supercilious, is commonly caught as bycatch in pelagic longline fisheries tar- geting swordfish. Little information is yet available on the biology of this species, however. As part of an ongoing study, observers sent aboard fishing vessels have been collecting set of information that includes samples of vertebrae, with the

Contemporary Methods for Capturing Juvenile Salmonids in the Marine Environment
ABSTRACT Anadromous salmonids play vital roles in marine and freshwater ecosystems. The most abundant of these fishes—Pacific salmon (Oncorhynchus spp.)—are integral to coastal ecosystems and communities across the North Pacific Rim, but numerous populations are experiencing dramatic declines, particularly towards the south of their range.

DNA Divers: Volunteer‐based eDNA capture for local and global marine biodiversity monitoring
Abstract Volunteer‐based biodiversity recording is a powerful source of scalable data yet to be used to its full potential by the scientific community. Coastal ecosystems are varied and diverse, making it difficult for managers to identify flexible methods for monitoring biological components.

Limited Evidence for Depth Specialism in Isolated Seamount Reef Predators
We investigated how depth influences predatory fish assemblages on seamount reefs in the Coral Sea using remotely operated vehicle surveys across a 100 m depth gradient. Predator abundance and species richness declined significantly with depth; yet assemblage composition remained largely consistent, suggesting many taxa utilise a broad depth range ...
