0 TN0017600030 - AT 25, 30, AND 35 DEGREES C LETHAL OXYGEN LEVELS ARE0.95, 1.03, AND 1.08 PPM RESPECTIVELY *TN5176* 00030 - AT 25 DEGREES C AND WITH D.O. NEAR SATURATION EMBRYOSDEVELOP PROPERLY, BUT AT LESS THAN 2.4 AND 4.2 PPM SURVIVAL IS STATISTICALLY LESS SOME WILL HATCH AT 1.7 PPM AT ALL REDUCED D.O.CONCENTRATIONS AT 25 AND 28 DEGREES C EMBRYO PIGMENTATION IS LIGHTER, HATCHINGPERIODIS EXTENDED, FEEDING IS DELAYED, AND GROWTH IS REDUCED *TN5176* 00050 - SURVIVAL OF YOUNG DURING FIRST YEAR IS MUCH LOWER IN CLEAR THAN IN TURBID PONDS (PROBABLY DUE TO INCREASED SUSCEPTIBILITY TO PREDATION) AND THIS IS PROBABLY ALSO TRUE OF STREAMS *TN5071* 00020- JUVENILES EXPOSED TO RAPID TEMPERATURE CHANGES HAVE SHOWNDECREASED SWIMMING PERFORMANCE *TN5176*
