The salmon run; an epic upstream journey

Salmon are one of the most well known creatures in our rivers, and every year they provide one of natures greatest spectacles; the salmon run.

This amazing annual journey takes salmon from the ocean to the rivers they were born in.

The journey begins with a gathering in the sea, where the salmon have spent between 1-4 years maturing, growing, and gaining strength. The salmon then wait at the river mouth for the autumn rains which will raise river levels, helping them to start their journey. Once they enter the river the salmon stop eating, with their sole focus being to return to the place they were born.

Over the coming weeks the salmon will risk their lives in their mission to reproduce (or spawn) whilst they take part in a literal uphill battle on their way home.

Successful salmon reproduce by creating dips in the bottom of the river known as ‘redds’ by flapping their tails. Females lay eggs in these redds, the male fertilises them, and the female covers the eggs back up. With their mission complete the salmon leave their eggs in peace and make the journey downstream to the sea.

It is estimated that only around 10% of salmon survive this journey, but those who do survive will make their way back to the same spawning ground every year.

It might seem that the odds are stacked against our brave warriors, and this is true. Not only do they make this journey on an empty stomach, losing weight, muscle and energy; they also face the risk of being eaten, attacks from other fish, and some man-made issues.

Perhaps one of the more troubling of these are rivers which have been modified by dams (or weirs) which the fish waste valuable energy that they just don’t have spare trying to jump. Some of these dams and weirs are so big that the fish simply cannot complete their journey.

Making rivers more salmon friendly is a huge part of our work. There isn’t a single resolution which will help, it takes time, teamwork, and many smaller changes to improve rivers. But we’re proud that one step at a time we’re making rivers a better place for salmon, as well as other wildlife, and as our rivers improve, we hope that in the future a greater percentage of the area’s salmon will be successful in their journey.

If you want to try and spot a salmon yourself the run usually starts from mid-October and carries on throughout November and December, ideally following a period of rain after a dry spell. As always make sure to be careful around water.

Volunteer event cancellations

Dear volunteers,

It is with regret that we announce that we are postponing all volunteer activity with Ribble Rivers Trust. We know there are many benefits to volunteering, including the positive boost to mental and physical health, the chance to meet others and contribute positively to your local area. However, given the ongoing Covid-19 pandemic and the most recent Government advice – asking everybody in the UK to stay at home and only go out for essentials such as food and medicine – we feel that continuing to include volunteers in the limited work we are able to do now would put people at unnecessary risk and be irresponsible. We all want to improve and protect our environment and rivers, but to do that we need to stay healthy and this must be our priority for the time being. We will continue to keep you up to date with the work we are able to do and will organise new volunteer days as soon as we possibly can. Please stay connected with us over the coming weeks and keep yourselves safe and well.

Refer to gov.uk/coronavirus for up to date information and guidance.

We will come through this and our environment and rivers will still need you, let’s make sure we’re all ready for it when the time comes.

Yours faithfully,

Jack Spees.
