a, Went out today but only thing i caught was the bottom ( loads of kelp on low water . had slack line after casting . What size weights you lot casting with
Answers - fish somewhere with a slightly cleaner bottom. A lot of piers have kelp closer in so ensure you cast 20+ yards to get past it. Use smaller hooks and baits to increase your catch rate. After casting, let your line settle then reel in slack until you feel a little tension. This may have to be repeated a couple of times until your tackle settles properly. You can use smaller weights when no tide pul and heavier grip weights where there is tide pull. Ensure your line is strong enough to cope with casting the weight to avoid risking serious injury or death to yourself or fellow anglers (ie use shock leader)
b, How do you manage to keep worms on hook after casting ( sure mine was dropping off on impact ( cotton ??)
Answer - Might sound a silly question but how are you putting your worms on? Not being derogatory but as a newby you may not know how to present them properly. I have seen many a fresh water cross over angler putting them on like lob worm and just hooking through the middle of the body which will virtually guarantee the worm to come off very quickly if not during cast. Thread the worm through the length of the body and it should stay on. As someone mentioned, a finger nail chunk of mackerel added to the end will ensure it is more secure (providing you make sure the hook point goes through the mackerel skin and not just the flesh.
c, When i ran out of bait ( see above ) would it have been any good trying some sort of feather or are they ony good for piers/ deep water etc
As said before always take extra bait. The last thing you want is to have a very productive session when the fish are biting instantly and have to go home as you've ran out of bait (even if it means taking extra mackerel rather than buying loads of worm if you don't have the funds). Feathers can catch you codling, coalies, Pollock and mackerel but be very careful to reel in fast or you will lose the gear. Only use when the sea is clear as hopeless if water is coloured.
d, On low water which piers are accessible (only free one i know is Blyth )
South shields and roker piers are accessible and free although both can be closed at times. Can still fish so far up shields towards the gate even if it is shut
