It only applies to black bass. This from the MDC website:
Lab testing done by the Missouri food safety commission has found that black bass over 15" caught from Table Rock lake, contain unacceptablly high levels of Mercury, Lead, Asbestos, and chlorade. Lab rats, upon being fed small portions of Table Rock origin black bass, developed serious cancerous tumors and expired at an early age. The state of Missouri strongly recommends that all black bass caught in Table Rock lake be immediately returned unharmed to the lake, and should not be used as food by humans or their pets. Consumption of black bass from Table Rock lake could result in serious health issues or even death.
