2.成蟹养殖。扣蟹投放后,水温达到摄氏10C以上就要开始投饵。5月底以前投喂些营养高的饲料,如:鱼、虾、螺蛳、蚌肉。6至8月底主要是红薯、土豆、南瓜(刀切煮六成熟便于下沉)和水草。9月以后到起捕前,随着水温的不断下降,食量逐渐减少,应以高营养饲料为主,12月份基本停食越冬。 饲料定时投放:每天上午10:00和下午6:00两次。注意观察,控制食量,以吃完、吃饱为原则,投放的饵料以下沉到池底为标准,不必定点,全池遍洒。这样既可避免争食,又能让它们就近觅食,为刚蜕壳蟹提供方便,也为蜕壳后的蟹子尽快“康复”减少活动量,及时补充必需的营养。这是定位无法比拟的效果。
2. crab farming. Crabs put release, the water temperature reached above 10C Celsius will begin to feed. By the end of May fed some nutritionally high feed, such as: fish, shrimp, snail, clam meat. 6 to the end of August mainly sweet potatoes, potatoes, pumpkin (knife cooking six mature easy to sink) and aquatic plants. After September, before the start of fishing, with the continuous decline of water temperature, the food intake gradually decreased, and should be based mainly on high-nutrition feed, basically stopped eating in winter in December. Feed timing: every day at 10:00 am and 6:00 pm twice. Pay attention to observation, control food intake, to eat, eat for the principle of feeding the sink to the bottom of the sink to the standard, do not have fixed-point, all over the pool sprinkle. This will not only be able to avoid fighting for food but also allow them to feed nearby and provide convenience for molting crab just as soon as possible after recovery. This will reduce the amount of activity as soon as possible and provide necessary nutrition in a timely manner. This is an incomparable positioning effect.
