Fish Species in Snowdonia’s Lakes, Rivers and Coastal Waters

Snowdonia is not one of the top fishing destinations in the United Kingdom due to its natural beauty alone but also due to an abundance of exiting fish species to catch. Gwyniad (Coregonus pennantii), a rare species of freshwater fish that is native to the Bala Lake of course is not allowed to fish for. Its population has dangerously declined due to poor water quality and introduction of ruffe eating the gwyniad’s eggs and fry.

Here are only a few of many fish you can catch in this National Park in north Wales:


Perch (Perca fluviatilis). The freshwater fish with red fins is usually angled for in autumn. Although it can get quite big in other parts of the world, do not expect to catch a perch heavier than 2.8 kilograms which is currently the record in Britain.


Roach (Rutilus rutilus). A freshwater fish species characterized for having red eyes is found in most lakes, rivers and ponds throughout Britain and is relatively easy to catch. However, there are not many places in the country where you can fish for roach and enjoy as spectacular landscape scenery as in Snowdonia.

Brown trout

Brown trout (Salmo trutta morpha fario). This fish prefers alpine streams which makes Snowdonia’s rivers and lakes a great place to angle for brown trout.


Carp. A species of freshwater fish is particularly popular among anglers because it is not easy to catch. Who knows, you may have luck in Snowdonia.


Salmon. It is not as common in Snowdonia as it used to be but it is still possible to catch it in some places during the “salmon“ season.


Tench (Tinca tinca). A beautiful and tasty fish can be found in several lakes in Snowdonia. To increase your chances of catching a tench, be sure to use a bait that submerges to the bottom because it is primarily a bottom feeder.


Bream (Abramis brama). This freshwater species prefers rivers and nutrient-rich lakes. It can reach an impressive weight which makes it very popular among anglers.


Mackerel. From the coastline of Snowdonia, you can catch mackerel. It is a migratory fish and is found around the British Isles only from April to September or October, varying from year to year.


Dogfish. The most common shark around the British Isles can be caught from Snowdonia’s coastal waters as well.

There are of course many other fish species you can catch in Snowdonia’s lakes, rivers and coastal waters, however, be sure to inform yourself when is the best time to angle for a particular fish species and where to find them. Some are found just about everywhere in the National Park, while the others can be fished for only in a few places at a particular time. However, due to the abundance of freshwater and saltwater fish you should be able to catch exciting fish species no matter at which time of the year you decide to go angling in Snowdonia.
