(Re)Pairing With Water: Climate Finance and the Prefigurative Positions of an Ocean Counter‐Politics
ABSTRACT This paper takes up recent calls to work ‘for and against climate capitalism’ to foreground the possibility of strategic engagements within capitalist structures that could destabilise its long‐standing exploitative dynamics. In doing so, it locates prefigurative positions of an ocean counter‐politics generated through novel blue financial ...

We Woke Up With a Sign: Exclusion, Conflict and the Politics of Marine Conservation in South Africa
Short Abstract Conservation often continues to be undertaken in ways that exclude nearby communities, despite extensive critique of such practices. This paper examines the reactions to the creation of a marine protected area in KwaZulu‐Natal. We find that the community supports conservation, but expresses frustration at not being included in decisions ...

ABSTRACT Aim The increasing anthropogenic pressures on freshwater biodiversity raise the important question: how well is it represented within protected areas? We address this question using the freshwater fish fauna of a neotropical biodiversity hotspot to estimate (i) how the fish fauna is covered by the existing protected areas and (ii) to which ...

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.
