Sea Trout Fishing

A Welsh Dee Sea Trout

The Welsh Dee is not known as a renowned Sea Trout river and angling effort is extremely low. Most fish are caught by Salmon or Trout and Grayling anglers during daylight hours. However, the Dee encounters annual runs in excess of 10,000 fish every year and the rewards of night time fishing on the river are great during the summer months.

Sea Trout begin to run the Dee in May and by late June can be caught in numbers on CADAC waters. The average size seems to be increasing and fish of 3 – 4lbs are relatively common whilst larger specimens make an appearance during the early hours.
