摘　　要：以双色鳗鲡玻璃鳗为试验材料,研究其对温度耐受性,并在10、20、30℃条件下,研究对盐度和pH值的耐受能力。双色鳗鲡玻璃鳗耐受极限温度为3℃和39℃,适宜温度为13～35℃。水温20℃条件下,适宜盐度和耐受极限盐度分别为0～1.9%和2.1%,适宜pH和耐受极限pH分别为4.0～9.0和3.0、10.0。水温30℃条件下,适宜盐度和耐受极限盐度分别为0～1.7%和2.0%,适宜pH和耐受极限pH分别为4.5～8.5和3.5、10.5。在非适宜10℃条件下,适宜盐度和耐受极限盐度分别为0～1.6%和1.9%,适宜pH和耐受极限pH分别为5.0～7.5和4.0、10.0,对盐度和pH耐受能力低于适宜温度条件。The tolerance range of the glass eels of Anguilla bicolor to water temperature were tested to be 3--39℃, and the most suitable temperature ranged from 13℃ to 35℃. The tolerance to salinity and pH were studied at water temperature of 10℃, 20℃ and 30℃. At 20℃, the suitable salinity range was 0--1.9%and the limit salinity was 2.1%l the suitable pH range was 4.0--9.0, and limit pH was 3.0 and 10.0. At 30℃, the suitable salinity range and limit salinity were 0--1.7% and 2.0%, the suitable pH range was 4.5--8.5, and the limit pH were 3.5 and 10.5, Under the unsuitable water temperature condition of 10℃, the suitable salinity range and limit salinity were 0 --1.6% and 1.9%, the suitable pH range and limit pH were 5.0--7.5 and 4.0, 10.0, all of which were lower than those under suitable water temperature.
