摘要: Abstract 1. Brown bullheads ( Ictalurus nebulosus ) were acclimated to temperatures of 7°, 15°, 24°, and 32°C for periods 10 20 days. The fish then placed in a thermal gradient the selected temperature recorded continuously one two 2. Immediately after placement gradient, four acclimation produced following temperatures: 16°, 21°, 26°, 31°C. 3. After hr, 7° 15°C selecting 25°C water, within day water 29–30°C. final preferendum brown bullhead is probably between 29°
