(a) Any person intending to stock fish in waters on privately owned lands shall submit an application for Private Fish Stocking Authorization, on forms provided by the Department, to the Chief of Fisheries at least ten (10) business days before the intended stocking date. A separate application is required for each body of water or stream for which fish stocking authorization is requested and for each time stocking is to occur.
(b) The Department may deny an application for private fish stocking if information is falsified on the application, or if the application is not completely and correctly filled out, or if the fish are requested from an unapproved fish hatchery, or if fish species requested are not compatible with species already present in the drainage or conflict with Departmental management goals for the drainage.
