通过测定不同水温下的采食率 ,间接确定澳洲鳗 (Anguillaaustrulis)的适宜养殖温度 ,并观察高温下的死亡状况和极限生存温度。发现澳洲鳗的适宜养殖温度接近于 2 4℃ ,略高于欧洲鳗 ,略低于日本鳗。在 18℃和35℃水温下 ,澳洲鳗仍有较强的采食率 ,致死上限温度为 37℃ ;鱼苗比隔年老鳗有更好的耐热能力
The suitable culture temperature of Anguilla australis was determined indirectly by measuring the feed intake at different water temperatures and the mortality and the survival temperature under high temperature were observed. It was found that the suitable cultivation temperature of Australian eel is close to 24 ℃, slightly higher than that of European eel, slightly lower than that of Japanese eel. At 18 ℃ and 35 ℃ water temperature, the Australian eel still has a strong feed intake, lethal upper temperature is 37 ℃; fry than the older eel has better heat resistance
