| 摘 要： | 本文报道了中华乌塘鳢对有关环境因子的耐受性及其生物学特性。中华乌塘鳢耐干露能力强,20h干露不死亡,耐温范为60.～35.0℃,耐盐范围为0～35‰,耐pH范围为6.5～9.0。中华乌鳢营穴居生活,体表能分泌很多粘液,繁殖季节雌雄配对,并具护卵行为。中华乌塘鳢是喜食鱼、虾、蟹、贝的肉食性鱼类,其体长与体重的关系为W=0.0000098L~(3.136082)。

| Abstract: | The tolerance to several environmental factors and biological characteristics of Bostrichthys sinensis were reported in this paper. The capacity of drily exposing to the light of day of Bostrichthys sinensis is great. It can survive 20 hours in drily exposing conditions. -The range of tolerant temperature, salinity and pH value are 6. 0 - 35. 0℃, 0- 35‰ and 6. 5 - 9.0, respectively. Bostrichthys sinensis lives in caves. Its skin secretes mucus. The female and male become to pair and have the behaviour of protecting eggs in the spawning season. Bistrichthys sinensis, a carnivorous fish, like to prey small fish, shrimp, crab and shellfish. The relationship between its body length and body weight is as follow; W = 0.0000098L3.136082. |
