Float fished fish strip or sandeel will catch mackerel, gar, pollack, wrasse and maybe a bass; bottom fishing over the rough will get thousands of wrasse, blennies and other small species with a chance of dogfish or gurnard. Congers are sometimes caught on big fish baits at night.
*The pump house supplies sea water to the new building within the car park area which processes the water to get sea-salt for the food-faddist; all salt comes from the sea, the supposed inferior salt from Cheshire mines being from the sea millions of years before man polluted it.
For your bait, the nearest place is a large angling shop in Helston, Atlantic Fishing Tackle in Wendron Street (just by a car park), that sells bait including ragworm and lugworm. Tel 01326 561640.
