VA I would go for just keeping some lmb/pan fish if the sole purpose of going with koi is for a side business............At the very least look into the state regulations to do so.I don't know about VA but NJ is a logistical nightmare.After you navigate the state red tape you then have the various viral and disease issues that the koi industry has been dealing with over the last few years.While I'm far from a expert on Koi a few farms I visited while in the process of getting my aquatic farmers license dealt with koi.They where pretty fanatical about keeping things bio secure in their operations.
