The source says Mostyn is best fished over low water. For the estuary as a whole it names flounder, dab, summer plaice, Dover sole (more likely near sunset), whiting, summer school bass and mullet, with codling in winter near the mouth and conger from the rougher, rockier areas. For flatfish it suggests size 1 to 2 long-shanked hooks on two or three hook rigs, and size 4 to 6 for Dover sole. Peeler crab is the top bait, with ragworm, lugworm and mackerel strip as alternatives. The map pin is on the Mostyn shoreline.
