Current and predicted ecological impacts of climate change to Atlantic salmon freshwater productivity in the North Atlantic.
Determining early marine survival and predation by endothermic predators on acoustically tagged Atlantic salmon (Salmo salar) post-smolts.
Atlantic salmon populations in North America and Europe have been declining for decades.
Marine mammal predation during their early life in the ocean might be a key reason for this decline, but it's hard to measure how much predation happens.
This study used acoustic telemetry to estimate how much mesothermic and endothermic predators contribute to salmon mortality.
Tagged salmon were tracked to see changes in temperature and depth, indicating predation. No salmon were eaten by mesothermic predators, and most endothermic predation was by marine mammals.
Overall, post-smolt mortality was low (13.1%-16.7%) with marine mammals responsible for 33.1%-42.9% of this (5.2%-5.6% mortality).
The study suggests that recent low returns of adult salmon are not significantly affected by marine mammal predation on post-smolts in their early ocean life.

A Mi’kmaw Perspective on Advancing Salmon Governancein Nova Scotia, Canada: Setting the Stage for Collaborative Co-Existence
Challenges and opportunities for Mi’kmaq Aboriginal and treaty rights to fish in Nova Scotia, Canada

The article explores Mi’kmaw Aboriginal and treaty-based fisheries, focusing on whether they should be viewed as legal constructs or as a value-based way of life.
It argues that Mi’kmaw fisheries are more than just legal rights—they are deeply connected to Mi’kmaw culture, governance, and values. Fishing is a central part of their identity, providing not only sustenance but also spiritual and cultural significance.
The article highlights the importance of Netukulimk, a Mi’kmaw concept of sustainable use of resources, as a guiding principle in their fishing practices.
The Canadian legal system often tries to regulate these fisheries through laws and policies, like the Fisheries Act, which can clash with the Mi’kmaw's traditional way of managing fisheries. Court decisions like R. v. Sparrow and R. v. Marshall confirmed Aboriginal rights to fish for livelihood, but the article argues these legal frameworks do not fully capture the Mi’kmaw perspective.
Ultimately, the article calls for a governance system that respects Mi’kmaw traditions and values, moving beyond purely legal interpretations to include their cultural and ecological approaches to resource management.
