Can I put my rock in crab traps and lower it in the gulf/bay for a month?
Can I use fresh water media to seed a salt tank?
The tank is a 210
in answer to the first question, yes you can.
Is it the wisest thing, No.
You run a very good chance of introducing unwanted pests/parasites into the tank. Most often "live rock" collected from the ocean is allowed to "die off" for a few days and then they are cured so that die off can decay and the rock get better populated by BB.
It can be done, but I would advise against it.
in answer to your second question, no, the salt will kill the bacteria colonies.
