Lure swimming action is very important, when targeting different species. The swimming action is determined by the size of the bib and body shape.

Big bibs make lures dive deeper, whereas, smaller bibs make them run shallow. Another factor is the angle of the bib. For further information see Bib design. Body shape can make the lure swim in a tight riggle or a wide slow swaying style.

The tighter lure actions are generally designed for quicker lure retrieves and are generally the minnow shaped lures or sleeker body shape.

Shorter or fatter lures with big bibs will dive deep, like slow to moderate retrieves, and swims with a wide slow wobble. If these lures are made to swim to quickly then they flip over and end up on top of the water. This lure action appeals to Murray Cod and Yellow Belly. For further information see Lure Design.
