冬眠过后,鳖即由鳃呼吸转变为肺呼吸。平时在水外觅食,晒甲;遇有惊吓,则潜入水中,每三五分钟便将吻端伸出水面呼吸换气。此时,如强行将鳖滞留水中(如网捕、笼捕),鳖即会因肺充水窒息,死亡。民间将此现象称之谓“水鳖”。 目前工厂化养鳖,鳖种的重要来源之一是依靠网捕和笼捕。网捕和笼捕一般从下网下笼至起网起笼约2—6小时,鳖被捕后,由于惊慌挣扎,肺活量增大,需加大气体交换,而在水中呼吸,便会呛入大量的水进入肺中。起网起笼时,鳖呈水肿状,体重约增加12
After hibernation, turtle that is converted from breathing gills to lungs. Usually foraging outside the water, the sun; in case of scared, then dive into the water, every thirty-five minutes it will kiss the end of the water out of the water breathing. At this point, such as forcibly staying turtle in the water (such as net catching, cage capture), the turtle will suffocate due to lung water and die. The phenomenon of civil society called “water turtle.” At present, one of the most important sources of turtle breeding and turtle breeding depends on net catching and cage catching. Net catching and cage catching are generally from the cage under the net to the net cage about 2-6 hours after the turtle was arrested, due to panic struggle, lung capacity increased, the need to increase gas exchange, and breathing in the water, it will choke into A lot of water into the lungs. When the net cage, the turtle was edema, weight increased by about 12
