The sea fishing around the U.K. on the beach or in the boat is very diverse and you need to make sure you have the right bait for your trip.
The core of your bait pack should be to look at the 4 main catergories.
worm baits are great for scratching around and an essential if you just want catch anything. Fish and Squid baits tend to work better for bigger fish, or can be cut into small strips for fish like Bream, Gurnards and Pollack, to name a few.
Shellfish such as Razorfish really come in to its own after a storm, its common to see various different types of Shellfish washed up on the beach after a big blow, so it makes sense to use what the fish will be naturally eating at thats time.
