krill is a small shrimp-like crustacean that lives in the ocean and they are the main diet for many fish species and marine mammals. In British Columbia, krill is often harvested and sold as bait for freshwater species such as trout, char and kokanee.
Krill can be bought in a frozen package from your local tackle store. They can be salted or cured before using. When using krill, simply thread one along its body onto the hook.
