I'll let the experts weigh in because I am curious as well. After last year's "Crawpocolipse" crawfish prices have gone down, but right now a 30 lb sack of crawfish is still $90-$100, which is fine for 3-4 friends to boil Saturday evening. But I am not sure the protein/weight ratio is worth the money. But I would say, if someone gave me a sack, I would throw them in there. But I can buy some high protein feed and think that may yield better results to the forage base and ultimately to the bass. Just my $.02. Also crawfish like to burrow and can lead to problems if you have a clay liner, or at least that's what I have heard.
