What is the best method for detecting Crevalle?
I need help with finding a way to make the fish come to my bait.
Often, the entry of fish from New Smyrna Beach, FL. Recently, I noticed a very good fish in the correct size in the dock, so I am on. The water is about 7 meters deep. 20 "+ perch, bream and 30 + shots.
The problem I have is of fishing with them directly, because the fish my line wrapped around a pole, only to be thrown out and hope that the fish find their way under me to finish Baiti columns that draw, it seems no luck.

I use combat power to light for 20 pounds.
I use all types of live shrimp for bait and lures Rapla-alcoholic beverages.
Live shrimp catch many striped catfish, I'm sick of it, because both edges were tingling.
How can I, in my bait to go 20-30 meters from the door?
If anyone knows, the favorite food Crevalle would help too!
Nor, as I have correctly set up a hook?
