为充分利用水体 ,提高九孔鲍育苗池的利用率 ,进行了以立体高密度笼养模式培育九孔鲍苗的试验。池岸上架设竹架 ,竹架上悬挂圆形聚乙烯塑料筛绢育苗笼 ,笼内用筛绢分隔成 4层 ,每层放置一块玻璃钢瓦。对照池采用传统的底养法育苗。试验结果表明 ,在池子面积、换水量和充气量基本相同的情况下 ,笼养法放苗量多 ,生长速度快 ,成活率高 ,还可节省水面 ,提高经济效益
In order to make full use of the water body and improve the utilization rate of the nine hole Baoying Miao pool, the experiment of cultivating the abalone with nine holes in three-dimensional high-density cage mode was carried out. On the shore of the pond, a bamboo frame is erected. A circular polyethylene plastic screen silk nursery cage is hung on the bamboo frame. The cage is divided into 4 layers by a silk screen and each layer is placed with a glass steel tile. Control pool using the traditional method of law nursery. The results showed that under the condition of the same pond area, water exchange capacity and aeration volume, the cage method has the advantages of more seedlings, faster growth rate, higher survival rate, water saving and economic benefits
