| 摘要: |
| 于2002年秋季在广西海洋研究所古城育苗基地和海滨公园育苗场进行大獭蛤(Lutraria(Psammophila)maxima Jonas)工厂化育苗研究。在育苗过程中采用成串的塑料片作为稚贝附着基立体附苗,使单位水体出苗量得到极大的提高。大獭蛤壳顶后期浮游苗至稚贝平均变态率为23.5%,小苗(大于8×104粒/500g)的平均单位面积出苗量为5.16×104粒/米2,大苗(小于或等于8×104粒/500g)的平均单位面积出苗量为1.42×104粒/米2,平均单位面积出苗量为3.29×104粒/米2。 |

| Abstract: |
| To improve the quantity of output, we studied factory breeding technique for Lutraria (Psammophila) maxima Jonas in Gucheng culture base of Guangxi Institute of Oceanography, during autumn 2002.Our results indicated that the larvae number per unit water body increase significantly profited from bunchy plastic slice as adhering substance for solid spat fall.The average metamorphism rate of larvae is 23.5% during seed-rearing period from the late apex of shell to the young shellfish.The average production of little seeds (>8×104 grain/500g) and great seeds (≤ 8×104 grain/500g) are 5.16×104 grain/m2 and 1.42×104 grain/m2 per unit area respectively.The average production was 3.29×104 grain/m2. |
