00040 - IN THE MONONGABELA RIVER IN WEST VIRGINIA, INHABITS A PH RANGE OF 3.4-7.7 *TN5167*. 00220 - ENDURES A MAXIMUM SALINITY OF 7.6 PPT *TN5167* 00020 - AT AN ACCLIMATION TEMPERATURE OF 21 DEGREES C THE LOWER LETHAL TEMPERATURE WAS -1.0 DEGREES C. HAS BEEN OBSERVED SWIMMING IN 37-38 DEGREE C WATER AND ENTERING 40 DEGREE C WATER FOR WORMS. IN A THERMAL GRADIENT TROUGH, THE BROWN BULLHEAD SELECTED 27.3 DEGREES C *TN5176* 00020S=WARM WATER, CAN SURVIVE IN TEMPERATURES AS HIGH AS 36.1 DEGREES C *842*. 00030S=CAN SURVIVE LOW OXYGEN CONCENTRATIONS; IN WINTER CAN SURVIVE AT 0.2 PPM OXYGEN *842*. 00050S=APPEARS TO BE LESS TOLERANT OF TURBULENT WATERS THAN THE BLACK BULLHEAD *1444*. 00290S=REPORTED AT 40 FT DEEP *842*; 00430S=ESTUARY *842*.
