Your permit plan: Stock triploid grass carp

The wait between stockings

PFBC

A grass carp permit is valid for the number of fish and the time period it states. PFBC policy is that permit holders wait two years before applying again for the same waterbody, and every new stocking needs a new application.

PFBC triploid grass carp permit

Pennsylvania Fish and Boat Commission (PFBC)

Form: PFBC-TGC-005 (rev. 7/24), mailed to PFBC

Fee: $85

You need a Pennsylvania Fish and Boat Commission triploid grass carp permit for each waterbody before you buy or stock triploid grass carp. The application fee is $85, and PFBC returns it if the permit is denied. Grass carp stocked under a valid PFBC grass carp permit don't need a separate Notice of Stocking; report them as that program directs.

What to have ready

• One application for each waterbody, with the fee (see the form).
• The exact surface area in acres (no range or estimate), plus maximum and average depth: try the pond size calculator.
• A photo of the installed outlet screen (or, if the pond never overflows, a photo looking toward the low point).
• A DEP approval letter if the screen is on a DEP-regulated dam.
• Latitude and longitude, or a map and directions.
• The plants you want controlled, with how dense each is.
• If the pond isn't entirely on your land: an application from every other landowner (no extra fee).

Screen the outlet so grass carp can't escape

PFBC

Water leaving a grass carp pond must be screened so the fish cannot escape: PFBC's form calls for bars or grating with 1-inch vertical spacing and a photo of the installed device, even for repeat applicants. A device on a DEP-regulated dam or its outlet needs DEP approval before it is installed, with the approval letter sent in with the application. If the pond never overflows, you show that instead, with a photo looking toward the low point.

Environmental Inspection Report (larger waterbodies)

PFBC

Waterbodies larger than 5 surface acres need an Environmental Inspection Report completed by a qualified biologist, fisheries scientist or environmental scientist. PFBC publishes these applications in the Pennsylvania Bulletin for public comment, which PFBC says significantly increases review time. PFBC may also ask for a report on a smaller waterbody.
