As the 2012 farm bill moves to the Senate floor, a scuffle has intensified over the inspection of catfish.

The battle pits the southern catfish industry and its supporters against a wider coalition of agriculture groups and fiscal conservatives.

The issue has potentially wide reaching consequences since it could affect the Obama administration attempt to craft an Asia-Pacific free trade area known as the Transpacific Partnership (TPP).

In this fight, catfish farmers actually want tougher inspection of their products while their opponents say they are trying to create an unfair system just to block imports of fish from Vietnam.
