River, stream and lake shorelines are an additional side. These can be extremely productive especially if they are steep or have downed trees or rocky shorelines. Coastline irregularities offer shelter to baby fish and food resources like crabs, crayfish as well as frogs. Additionally, these financial institutions are where insects take bad hops as well as drop in the water, providing added chances for a fast dish. Downed trees and stones offer shelter from currents and places for the predator fish to hide.
The next time you go fishing, try to find anything uncommon and try a few casts there. It could be a color change in the water, a washout from the beach, a bulkhead or boat dock, a jetty, etc. They all offer shelter or food to the little men which brings the killers.
