Boilie a boilie is a hair rig (the bait is not attached directly to the hook) which allows the boilie to sit off the back of the hook. This not only means that the bait will behave more naturally in the water (for example when disturbed by feeding fish) it also will often make the difference between a good hook hold and a bad one. Due to the nature in which a carp feeds the bait is blown out of the mouth soon after it has been picked up and the fact that the bait can move independently from the hook
Catch and release hooked in the mouth, but observed that they did reduce mortalities compared to barbed hooks if fish were hooked deeper. The study also suggested bait fishing does not have a significantly higher mortality when utilized in an active style, rather than a passive manner that allows the fish to swallow the bait. The effects of catch and release vary from species to species. A study of fish caught in shallow water on the Great Barrier Reef showed high survival rates (97%+). for released fish if handled correctly and particularly if caught on artificial baits such as lures.
