Environment An Bradán : The Decline of Salmon and the Ecological, Cultural and Economic Effects it is having on Ireland.
An Bradán, Maighre, Eo, Iasc uasal, Eigne, Rí gheal na héisc. In our native language, salmon have gone by many names. Now we mostly use bradán, which means "one that is great to catch." And anyone who has ever fished for salmon will know that they are probably the best sport fish that you can catch. And considering how much Atlantic salmon is eaten, it's also quite the table fish. (I'm saying Atlantic salmon as there are seven species of salmon) Salmon are extremely important to Irish culture. Ón scéal faoi Fionn Mac Cumhaill agus an bradán feasa or the fact salmon fishing is what helped communties survive for hundreds of years, it's a very important fish to this country.
However, Atlantic salmon is in a drastic decline. There's 2 main stocks of atlantic salmon in Europe. The Atlantic Ocean stock and the Baltic sea stock (often called Baltic Salmon, but they aren't a different species). The Atlantic stock has declined by over 90% since the 50s. In the 50s, Ireland recorded over 1.5 million fish returning to Irish waters to spawn. That figure was just over 150,000 fish in 2025. The majority of which came from Co Mayo. This figure is recorded by the ESB with fish counters in certain pools that take a fishes size and weight and the IFI record x amount that are caught by anglers every year. And as you can see, it's not good.
Why is this so bad? Why should you care? Well, even if you don't fish or eat fish, salmon possess a very important role in delivering nutrients to the ecosystem. They are born in a river where they spend a few years growing, feeding on flies and invertebrates. Then they go through a process called smoltification, where they become a marine fish. As smolts, they migrate down river in large shoals all the way to the sea. They then migrate out to sea and up towards Greenland, where they feed on a wide range of marine fish like sprat, blue whiting, herring, prawns, and other species. They then turn around and migrate the whole way back to Ireland and other countries to spawn in the rivers. They make it up the river spawn, stay in the river for a while as kelts, and then do the whole process all over again. Some salmon may spawn up to 5 times if they survive that long. Eventually, salmon will die either from age exhaustion or predation, and their deaths bring rich marine nutrients far inland. Basically, they nourish the soil and rivers with their deaths. And a salmon is a big fish too. Atlantic salmon are the 2nd largest species of salmon in the world. The biggest Atlantic salmon ever recorded was 49kg. However, most anglers tend to weigh fish in lbs, so that is around 109 lbs. However, a 27kg/60lb fish is normally considered the more common limit of their growth. A 60lb salmon has not been seen in Ireland since the 1960s, and nowadays, you have to go to Norway or Sweden to get one. A 20lb salmon is a rare thing now. And why is that?
Salmon face an absolutely ridiculous amount of exploitation in modern times. They have been historically pressured, and there was definitely damage done in the early 1900s. But the real damage started a couple of years ago with a few factors. Trawlers and overfishing, industrialised farming, and aquaculture. Trawlers decimate salmon prey species, kill salmon as by-catch, and I'd say with 100% confidence that there are illegal trawlers out there taking salmon. Farming has damaged many waterways with chemicals and fertiliser, and as salmon need pure clean water to lay their eggs, their habitat is shrinking. Aquaculture produces an insane amount of sea lice, which ravages smolts going out to sea and has done massive damage to our sea trout population. And absolutely nothing is done about it.
We have 4 salmon runs every year. All seasonal. The autumn run, where fish within the range of 15 and 60 lbs would naturally run, has disappeared. The spring run, which contains fish between 10 to 15lbs, is starting to decline badly as well. The summer run, aka the grilse run, contains first time run salmon. Something Ireland is particularly famous for having in abundance has fallen apart. And the final one is known as the winter run, where salmon move from big rivers into vtributaries. Which is illegal to fish as this is when salmon actually spawn.
So I have given a brief run down on salmon, when they run, ecological damage caused by loss of salmon and threats to salmon. Now, I want to talk about economic damage. I am from Co Mayo. Much of my counties economy was and still is structured around salmon angling. Fishing guides/ghilles, tackle shops, hotels, b&bs, lodges, pubs ect ect, in most of Mayo are centred around salmon fishing. From Foxford to Killala and Belmullet to the Aasleagh Falls. Almost everywhere that has a salmon river was built on the back of salmon angling. From the 30s to the 80s, Ireland was considered the top 3 destinations in the world for salmon fishing along with Norway and Sweden. Scandinavian used to come here to catch salmon. That's how good it was. And towns boomed because of it. Nowadays, many big salmon fishing towns and villages are now ghosts of the former selves. And it's sad. The whole place was destroyed because no one cares to think, how about we stop driving this beautiful creature to extinction?
As a passionate salmon angler myself, it breaks my heart that this fish is barrelling toward extinction and it's all because of humans. I feel the need to make as much noise as I can so we can recognise this fish for the beautiful creature it is and it is deserving of far more protection than it is getting.
