团鱼,又名甲鱼或又称鳖。当前,农村养鳖户增多,有的赚钱,有的赔本。总结经验,笔者认为广大农户养鳖应注意把握以下九个环节: 1、建池:鳖喜静怕惊,喜暖畏冷,池要建在环境安静、避风向阳的地方,大小根据养殖规模而定。池底最好掺些细沙,四周要砌1米高的围墙,墙脚要入土20～40厘米。池内搭若干个晒台和摄食台。 2、选种:从外购苗必须注意质量,伤鳖、病鳖或用钩、药、电捕的鳖都不能作种。此外,冬眠受冻的和恒温室养的鳖也不能作种。最好是从可靠的养殖场或可信的专业户购买种苗。 3、分级饲养:大小鳖不能混养,否则易造成大鳖咬伤甚至吞食小鳖,而小鳖难以抢到食物,生长发育不良。有条件的,最好是将稚鳖、幼稚鳖、成鳖及亲鳖分池饲养。 4、亲鳖搭配比例:一般雌雄比例以3:1或4:1为佳,雄鳖过多、过少或混养小规格的鳖,都会影响亲鳖的交配和受精繁衍。 5、控制密度:一般每亩水体放同一规格的苗种100～200公斤,具体投放量应视养鳖者的管理水平而定。
Tuna, also known as turtle or turtle. At present, raising turtles in rural areas increased, some make money, and some lose money. Summarizing the experience, I believe that the majority of farmers raise turtles should pay attention to grasp the following nine aspects: 1, build the pool: soft-shelled turtle scared, warm and cold, the pool to be built in a quiet environment, sheltered sunny place, according to the scale of breeding size set. The bottom of the pool is best mixed with fine sand, surrounded by a 1-meter-long wall to be built, foot wall to soil 20 ~ 40 cm. Pool take a number of terrace and feeding Taiwan. 2, selection: Miao Miao from outsourcing must pay attention to quality, injury turtle, sick turtle or hook, medicine, electric capture of turtle can not be used as seed. In addition, hibernation frozen and thermostat-fed turtle can not be used as seed. It is best to buy seedlings from a dependable farm or credible specialist. 3, grading feeding: the size of turtle can not polyculture, otherwise easy to cause big bites or even swallow small soft-shelled turtle, and turtle difficult to grab the food, poor growth and development. Conditional, it is best to juvenile soft-shelled turtle, soft-shelled turtle and soft-shelled turtle breeding. 4, pro-turtle with the ratio: the general ratio of male and female to 3: 1 or 4: 1 is better, male turtle too much, too little or polyculture small turtle, will affect the pro-turtle mating and fertilization. 5, control density: General per mu of water to put the same specifications of the seed 100 to 200 kg, the specific amount should be depending on the level of management of turtles.
