North Wales Fly Fishing – Fish Species

North Wales fishing is not just renowned for its vast water abundance but also for the diverse range of fish species that you can target with fly fishing techniques. In this section, I will delve into the best species to pursue on the fly in North Wales.

Brown Trout

Brown trout are the preferred game fish for fly fishing in North Wales. They are widely distributed and provide an exciting fight with the right gear. Unlike farmed rainbow trout found in closed-off lakes, brown trout offer a more robust challenge as they constantly battle the river’s current, ensuring their fitness.

Atlantic Salmon

Atlantic salmon are the most sought-after fish in North Wales. They can reach impressive sizes and offer an exciting challenge for fly anglers. However, they are not recommended for beginners, so consider hiring a guide if you aim to catch your first Atlantic salmon in Northern Wales.

Rainbow Trout

Rainbow trout, while not native to North Wales, are abundant in most stocked lakes. These fish grow quickly due to fish farm feeding practices and can provide a fun fishing experience. They are an excellent choice for beginner anglers or young enthusiasts who may lack the patience for other types of fly fishing.


Pike is a challenging yet rewarding target for fly fishing in North Wales. Known for their ferocity and powerful pulls, catching pike requires expertise. It is strongly advised to enlist the help of a guide, especially if you haven’t caught a pike before. Handling them out of the water is tricky and necessitates specific tools like landing mats and pike forceps.


Mackerel are one of the easier saltwater species to catch on the fly. They are recommended for anglers looking to experience something unique. Mackerel provide a surprisingly strong fight for their size, and it’s possible to hook multiple fish at once when using a dropper.

Sea Bass

Sea bass are another prized target in North Wales, offering an exciting fight for fly anglers. Some instances involve saltwater bass striking flies on the water’s surface, displaying power and aggression. Targeting sea bass is highly recommended, not only for their fighting ability but also for their stunning appearance.

Mullet are pound-for-pound among the most challenging fish to catch on the fly in North Wales, rivaling Atlantic salmon in this regard. They are often selective eaters, and fishing on hot days or using bread bait to chum the water can increase your chances of success.

North Wales Fishing Report

During my last fishing trip to Wales, I ventured into the sea with a fly rod and used an olive Surf Candy. I had a successful outing, landing impressive pollock and small coalfish. 

The fish were remarkably aggressive about two hours before high tide, actively pursuing shoals of smelt. Casting directly over these shoals proved to be highly effective.

While the fish put up a great fight, they were relatively easy to handle, especially the pollock due to their manageable size. I quickly took pictures with them and released them back into the water to ensure they could be caught another day.
