Why is my crawfish coming out salty?

I cleaned my crawfish in salty water drained and cleaned again . Added the seasonings to the water then cooked them however at the end of the bowl I noticed the water from the live crawfish was Brown not clear? Could this be the reason why they came out salty? Also is it possible the crawfish boil seasonings made it salty? I added the whole bag because we wanted really spicy?

Yes, the pre-packaged 'boil' seasoning is VERY SALTY. If u want more spiciness (heat) use ground red pepper with the boil mix, or add a good squrt of Sriracha to the water. You prepped the crawfish fine. Saltwater, then clean. Then boil.
