From 2023 GAC newsletter: River Taff – Good bags of Grayling for those who enjoy trotting a float especially around both Radyr and Gabalfa sections. Plenty of wild trout on all stretches and a few good Barbel reported. For those of you who enjoy river fishing, The club have now stocked the Llandaff North stretch between Llandaff weir and Hailey park with Roach and Bream, so well worth giving it a go. Below Black weir has provided good sport for both Game and Coarse anglers.
