Hello all.  I believe I have the answer to my question, but I would like some opinions from the experts on here.  I have a small river that feeds into the brackish Arthur Kill between NJ and NY.  it is a fairly urban area and i do not trust that the river does not have contaminates in it.  What are your opinions on catching the small fish in there with a trap, freezing them, and then feeding them to piranhas.  Would freezing them remove all parasite concerns?  Should i be worried about contaminates?  I believe the area around the river used to be very industrial prior to cleanup.
