在全埋式无地沟无法吸污的育苗条件下,利用鲜活生物活饵料进行中华绒螯蟹(Eriocheur Sinensis)俗称河蟹的大棚育苗,配套生物饵料培养池50,000m2, 育苗水体1,680m3,平均每m3育苗水体培育出河蟹大眼幼体0.289kg。共育河蟹大眼幼体486kg,其中试验池为1,520m3水体;单位水体出苗量为0.314kg,对照池为160m3水体;单位水体出苗量为0.190kg。试验池比对照池每m3水体出苗量增产39.5%。
Under the condition of nurturing seedlings which can not absorb sewage completely in the whole buried land, Eriocheur sinensis, commonly known as crab nursery, is equipped with live bio-food bait, supporting 50,000m2 of biological feeding ponds and 1,680m3 of nursery water body, m3 nursery water to cultivate crab Euglena 0.289kg. A total of 486kg of crab-adult eyed juveniles were trained, of which 1,520m3 water was used as experimental pond; the amount of emergent water per unit of water was 0.314kg and that of control pond was 160m3; the amount of emergent water per unit was 0.190kg. Compared with the control pond, the test pond increased the yield by 39.5% per m3 of water.
