Lake St. Joseph waters have size limit regulations that require the live release of angled walleye, along with a possession limit of 4 walleye and 4 northern pike. The following are some tips for the successful release of angled walleye.

• Use artificial lures and barbless hooks if you intend to release your catch.
  
• Land the fish quickly.
  
• Avoid the use of landing nets constructed of abrasive material that could remove the protective mucous coating of the fish.
  
• Minimize handling and unhook the fish while still in the water if possible.
  
• If the fish is hooked deeply, cut the line and release the fish.
  
• Never place your fingers through the gills or in the eyes of a fish you intend to release.
  
• Artificial air bladder deflation (fizzing) for walleye caught in deep water is not recommended.
  
• Never place walleye on a stringer if they are to be released.
  
• Ensure the fish is breathing, in an upright position and can swim away under its own power before releasing.
  
• If resuscitation is required, move the fish gently backward and forward through the water so that water passes over the gills.
  
• Gently release the fish headfirst.
