Craws and Prespawn Bass

You don't have to be a fisheries biologist to figure out that bass love to eat crayfish. All you need to do is to walk around your local tackle shop and take a look at how many baits are shaped like or painted to resemble the little freshwater crustaceans.
Bass are especially fond of crayfish during the prespawn period, and because of that you'll have major success in the spring by fishing craw patterned baits like the BioSpawn VileCraw, Strike King Rage Craw or a crawfish patterned crankbait.

It's not just their general love for crayfish that makes bass go gaga for crayfish in the spring time though. Interestingly, there is a biological reason for it, and it has everything to do with the upcoming spawn.

Compared to shad, bluegill, or other common bass forage, crayfish have extremely high levels of minerals like iron, calcium, and magnesium built up in their shells. In the spring, bass require much higher inputs of these minerals to build their eggs, so they try to eat as many crayfish as they can.

To most effectively capitalize on the prespawn bass/crayfish relationship, try fishing rocky areas like rip rap, bridges, points, and bluff walls in the spring. Crawfish make their homes in the little nooks and crannies in the rocks, and prespawn bass spend lots of time combing those areas over for crayfish.

Try rigging a BioSpawn VileCraw on a 1/2 ounce wobble head and slowly reeling it around rocky points. The tantalizing flapping motion of the VileCraw will be sure to generate devastating strikes from hungry prespawn bass looking for a snack.
