By LSU AgCenter. White Spot Syndrome Virus (WSSV) has been confirmed for the first time in Louisiana in crawfish / crayfish from a pond in St. Martin Parish.
This crawfish disease seems to affect mostly the medium to large crawfish / crayfish. Symptoms include sluggish crawfish that don’t move much once they are dumped from the trap. They do not pinch hard and can’t walk. There are no color differences or obvious signs other than weakness and slowness. Some dead crawfish are noticeable in the traps while others are noticeable in the shallow water along the edge of the pond.
