How do Farmers Farm Crawfish?

[BananaTom]

I am old school and know how crawfish were once caught in the wild. Then the pond raised crawfish arrived. I know cow pastures were transformed. I know rice and crawfish are a good marriage.

However, on another thread here when asking the price of bugs in your area, a response included the fact that there were costs associated with raising crawfish.

It sparked my curiosity. I can see a cost in the harvest of bugs, i.e. traps, bags, vessel, transportation and labor.

How do Farmers actually Farm Crawfish?

Thank you
