Hi Howard....
I fish Cornwall a lot, one of the marks I use for Wrasse is the southern end of Harlyn Bay. just south of Padstow.
Park on the surfers car park near the Harlyn Inn, at half tide down, better on a mid size tide, certainly not a spring, and walk the length of the beach . At the end of the beach is a cottage called FIsh Cellars, an easy climb up the low cliff, only about 12 feet or so, with many places to choose from,or just walk up the private slipway to Fish Cellars if the tide is far enough out.Walk around to the right, you will have to cross an old quarry, and then you will reach a point with the beach to your right and the open sea to your front. There are a few rock marks to choose from, the water is quite deep but easy to fish if using a float,which is a method I really like myself. It is a snaggy bottom so it is best to check the depth and fish a foot or two shallow, that way you will get bites but if you are quick you can get the wrasse up and away from the snags .
The area you are fishing is called Cataclews, the next bay down is Mother Iveys Bay.A bit further along there is Cataclews quarry, which is a good local mark for Conger.
For the Wrasse, bait wise I usually use either frozen sandeel, available from the tackle shop on Padstow, or the Garage in St Merryn, or live Prawn which can be netted at the top, or bottom of the tide off virtually any beach.Personally I think that Peeler Crab is a waste of money for Wrasse, as they will hit Sandeel , Prawn, Small hardbacks, Mussell, even a Mackerel strip well enough, which reminds me, being a rock mark it is a good place to feather up a few mackerel as well, there are also Pollack to be had , but mainly the wrasse .
Soft plastics will also catch their fair share of fish, but it is better to experiment and see what the fish are wanting .
You will very likley catch Bass as a bycatch, nice, but even if sizeable the current legislation means they all have to go back .
There will no doubt be surfers using the bay, but they never bother you at Cataclews because of the rocks, preferring to have a nice beach to approach from the sea!
Harlyn Bay itself produces Bass on an evening on a flooding tide, but as most beaches in Cornwall, the surfers and bodyboarders can be a problem.
Another Mark is just to the right of Trevose head Lighthouse, I fish there for Wrasse as well, but because it is quite high, and a vertical drop I dont floatfish I use a rotten bottom rig and a single paternoster with small hardback crab.
The takes are violent, and you have to winch the wrasse up about 30/40 feet or more, plus the route down is not easy so not for the fainthearted.
Hope this helps.
