you can punch pieces of apple or potatoout andfish them i have seen bob nudd doing a couple of articles onit, he then stained them with a bit of coffee to make them resemble pellets.you can buy a seafood pack from most supermarkets with squid and mussels and other things in it they are all good for bait.also luncheon meat, pepperami,meatballs,catmeat,sweetcorn,chick peas,well preparedmaize,maggots, worms and if they are allowed on the water nuts are an excellent bait but they must be prepared wellthe list goes on and on but dont try them all at once the trick is to get the fish feeding on what you are introducing so pick a couple and try them for a few sessions if one starts to produce base your main line of attack on that but keep experimenting you may find the bait that will take the lake apart this winter but you may also find that they just dont eat much of anythingin winter on your lake.
