White crawfish have greenish fat not that great and red crawfish have the yellow fat that's the ones you want to suck the heads on.

When I was comm fishing, toward the end of the season, when no one wanted to eat crawfish anym, farmers bought em from me for $20/sack. They were restocking for the next season.

Here's a bit of trivia. The stuff referred to fat is actually pancreatic material.

Yes there is $$$$ involved with raising crawfish. However I know someone that runs 5 boats (hired hands) and makes $12,000 to $34,000 per week depending on price. So your could work it really hard for 4 months, take off 8 and make a real good living. The major player acres. You have to own it or lease it. Thats the most expensive and why we all don't get into it.

I promise you he is not taking those 8 months off with a operation like that. Does he farm the rice on this crawfish farm also?
