Usually ground-bait or chum used to form a trail to attract fish to you or your bait.
Mostly used by trolling anglers or anglers fishing from a boat.
However I felt that this shouldn't prevent shore anglers (from piers or jetties) to use this very good innovation.
First the ingredients: The trick to successful berleying is to have the correct combination of ingredients, consistency of the flow and timing, and to my way of thinking those anglers who don't use berley are mad, as it would have to be the most effective way of attracting the fish to you.
But when using berley, no matter what the combination is, you need to use it as a technique of getting the fish to you.
Not as something that feeds the fish or takes them away from you.
The main thing that you have got to remember is that the largest object that is floating down that berley trail is your bait with a hook in it.
I used a used cheese cloth and dump some fish intestine, ground baitfish, some prawn paste (Belachan- for those in Asia) and some prawn heads.
Then I simply tie this to my main line with a swivel.
Obviously I can't be casting far with this setup hence i fish by the jetty ...
and results were great.
I was also thinking of doing a modified "cable car" rig where the berly will trolley along my main line after casting till the depths I wanted.
Keep and open mind and stay ahead of the learning curve.
