In waters where native and exotic species now exist, the native species shall be definitely encouraged. In waters where exotic species are best suited to the environment and have proven of higher value for fishing purposes than native species, plantings of exotics may be continued with the approval of the Director and the superintendent of the park in which such waters are located. It is the definite purpose of this policy to prohibit the wider distribution of exotic species of fish within the national parks and monuments, and to encourage a thorough study of the various park waters to the end that a more definite policy of fish planting may be reached. In waters where the introduction of exotic species threatens extinction of native species in an entire national park or monument area, such plantings should be discontinued and every effort made to restore the native species to its normal status. The number of any species of native non-game fish should not be reduced even where such reduction may be in the interest of better fishing. All forms of artificial stream improvement which would change natural conditions should be avoided, but the restoration of streams or lakes to their natural condition is permissible where thorough investigation indicates the desirability of such action. There should be no effort to introduce exotic fish or other exotic aquatic life for the purpose of increasing the supply of fish food. In cases where a lake or stream is of greater value without the presence of fishermen, there should be no stocking of such waters. In national parks and monuments where there still remain certain lakes which do not contain fish, permission of the Director must be secured before stocking. PLEASE ACKNOWLEDGE RECEIPT OF THIS ORDER.
