去年八月,买进七万尾红鳍东方纯幼鱼,除死亡剩余三万尾。因为买的季节晚了,加之鱼体又小,五至七克,虽然价格便宜,但刚刚放进筑堤内不久,到处都漂着死鱼,清楚的知道这批幼鱼质量有问题。但是以后担心的同类残食,几乎没有发现,而且养殖的非常顺利,成活率也维持在近90％,能有这样高成活率的秘密,就在于筑堤式养殖。筑堤渔场长120米,宽90米,有11,160平方米广阔;水深浅处4.5米,深处达12米;因为底质是砂地,环境无可挑剔。渔场内蟹虾等甲壳类及海藻类丰富,象在天然条件内 In August last year, the 70,000-tailed Redfin Oriental purefishes were bought, except for the remaining 30,000.

However, the same type of residual food that was later worried about was scarcely discovered and the breeding was very smooth with a survival rate of nearly 90%. The secret to such a high survival rate lies in the dike farming. The embankment fishery is 120 meters long and 90 meters wide and has a vast area of ​​11,160 square meters. The water depth is 4.5 meters and the depth is 12 meters. Because the sediment is sandy, the environment is impeccable.
