1.供给优质饲料饲料须以动物性为主,稚鳖饲料必须含蛋白质50%,日投料为其体重的1.5~2.0%。鳖料配制比例为:鱼粉35%、麸皮30%、大豆粉20%、面粉7%、谷芽3%、骨粉1%、食盐1%、植物油1%,加适量水搅拌,压成条状或颗粒状。2.提高产卵量提供蛋白质饲料,配合饲料与活鱼、虾、蚌、螺等各半投喂;在水温保持30℃条件下,每天保持14小时的光照,母鳖可常年产卵。3.人工孵化自制若干个边长10厘米的盒子,盒内铺设含水量7~10%的细沙,厚3厘米,用食指在铺平的沙土上划出2厘米深的小槽,把鳖卵置于小槽内。卵上放2厘米厚的细沙,再放第二层,将盛卵盒放入温箱内孵化,温度控制在30℃,相对湿度为80~90%。4.加温饲养鳖在常温28~30℃寸,生长最快,若水温低于20℃,其生长明显减慢,进入冬眠。因此,冬季加温饲养可促进幼鳖生长,缩短养殖周期,使商品鳖的饲养期缩短为1年左右。特别是有地热资源以及终年气温较高的地区,更应大力发展养鳖业。
1. The supply of high-quality feed should be animal-based feed, juvenile turtle feed must contain 50% of protein, daily feed for its weight of 1.5 to 2.0%. The preparation proportion of turtle material is as follows: 35% of fish meal, 30% of bran, 20% of soybean meal, 7% of flour, 3% of grain buds, 1% of bone meal, 1% of salt and 1% of vegetable oil. Or granular. 2. To improve the amount of eggs to provide protein feed, feed and live fish, shrimp, mussels, snails and other semi-fed; kept at 30 ℃ water temperature for 14 hours a day to keep the mother turtle eggs can be perennial. 3. Artificial hatching a number of homemade side 10 cm box, the box laying sand with water content of 7 to 10%, 3 cm thick, with the index finger in the flat sand to draw 2 cm deep small groove, the turtle Eggs in the small tank. Put eggs on the 2 cm thick sand, and then put the second layer, the egg box will be placed in the incubation incubator, temperature control at 30 ℃, relative humidity of 80 to 90%. 4. Heating turtle at room temperature 28 ~ 30 ℃ inch, the fastest growing, if the water temperature is below 20 ℃, the growth slowed down significantly, into the hibernation. Therefore, heating in winter can promote the growth of juvenile soft-shelled turtles, shorten the breeding cycle, shorten the breeding of commercial turtle for about 1 year. In particular, geothermal resources and high temperatures throughout the year, more should be vigorously develop turtle breeding industry.
