A new paper entitled “Using Food Webs and Metabolic Theory to Monitor, Model, and Manage Atlantic Salmon—A Keystone Species Under Threat“ provides an insightful exploration of how we might combine data and theory to develop new modelling approaches to predict and manage how Atlantic salmon will respond to future changes.

Led by Guy Woodward at Imperial College London and published in the journal Frontiers in Ecology and Evolution, the paper includes the Missing Salmon Alliance Principal Investigator Colin Bull and Rasmus Lauridsen (Head of Fisheries Research for GWCT) amongst its 15 authors.

The paper sets out a need for developing new mechanistic modelling approaches that make use of data-gathering initiatives, such as those being delivered by the Missing Salmon Alliance (missingsalmonalliance.org). The paper also emphasis how large scale international research projects such as SAMARCH (samarch.org), are integral to providing a greater understanding of the growth and survival of salmon at sea. It outlines how understanding key aspects of the food web and environmental drivers affecting salmon life stages enables us to forecast responses to changes more accurately and facilitates future salmon management.

The paper calls for more joined-up Atlantic salmon research, a more holistic approach to continue to identify bottlenecks in the life-cycle and drivers thereof helping to direct focussed and effective management solutions. This all falls directly in line with the Missing Salmon Alliance’s mission: to drive action to save our wild Atlantic salmon from extinction by combining expertise, coordinating activities, and advocating effective management solutions.

Managing the water

When are we actually going to see thorough testing of our waterways and testing of household chemicals and their effect on river ecosystems. The salmon/sea trout stocks in west wales have declined since the 1980's this seems to have coincided with the increase in dishwashers and Cillit Bang type chemicals, All the major rivers have sewerage farms near their sources. NRW only check water quality and have refused to check the silts for pollution. I have not fished for salmon/sea trout for the last 5 years due to my disgust in the state we have let our rivers be polluted to the point they cannot support sportfish. It is time for a complete holistic approach ant thorough testing. Paul
