| 摘 要： | 为改进菲律宾蛤仔垦区育苗技术,设置一口池塘(A)培育高密度浮游植物并定期添加至育苗池(B),未添加藻类育苗池(C)作为对照,比较了A、B、C以及邻近自然海区(D)的水体、沉积物、浮游植物状况和池塘B、C中稚贝生长情况。结果显示,池塘A、B、C之间水质和沉积物各指标无显著性差异,但三者水体中盐度、pH、溶解氧、氨氮、硝酸盐氮、活性磷酸盐和沉积物中有机碳、硫化物与自然海区D差异显著;浮游植物密度ABCD,但仅A、D间差异显著;池塘B稚贝壳长和密度均显著大于池塘C。这表明垦区与自然海区环境差异大,而育苗期间通过外源补充藻类能提高稚贝的生长率和成活率,进而提高菲律宾蛤仔垦区育苗成功率。

| Abstract: | The Manila clam (Ruditapes philippinarum), with annual yield of 4 million tons in 2015, is a kind of important economic shellfish in China. The breeding technique in diked tidal flat which is the most productive technology, is not particularly reliable. In order to optimize it, a pond (A) was set up to induce phytoplanktonic blooms, which was regularly distributed to the nursery pond (B), and nursery pond (C) without algae superinduced as the control. The water, sediment quality and phytoplankton of A, B, C were compared with those of adjacent natural sea area (D). The growth of juveniles in B and C were also compared. The results showed that, there was no significant difference between A, B and C in water and sediment quality, but the water quality parameters(S, pH, DO, NH3-N, NO3-N, PO4-P) and the sediment quality (organic carbon, sulfide) of the three ponds were significantly different from D; the phytoplankton density followed the order of A > B > C > D, but only A had significant difference with D; the shell length and density of juveniles in B were significantly higher than those in C. This indicated that there was a great difference in the environment between the diked tidal flat ponds and the natural sea area, and phytoplankton supplement can increase the growth and survival of the juveniles, thus ensuring the success rate of the breeding of R. philippinarum in diked tidal flat ponds. |
