| 摘要: |
| 本文对泉州湾和围头湾翡翠贻贝的生殖腺性状、繁殖期、幼虫数量分布、附苗期及海区半人工采苗技术进行了研究。两湾翡翠贻贝繁殖期为5-9月,5月中旬至6月中旬为繁殖盛期,主要的附苗季节在6月中旬和7月上旬。选用胶胎绳和棕绳为采苗器,附苗效果较好;并讨论了投挂采苗器的适宜时间。 |

| Abstract: |
| Perna viridis (green mussel )is a warm-water bivalve mollusk with attributes of rapid growth, high production, great reproductive capacity, as excellent prospects for marine aquaculture.
This paper presents the results of a study on the spawning period, larval ecology, settling period, semi-artificial spat collection and determination of optimum sea areas enviromental factors (temperature, salinty PH, transparency clarity and phytoplankton).
The spawning season of green mussel in the Quanzhou area is in May to September, when seawater temperature is 23-26 C. Observations showed the spawning peaks from middle of May to June; settling stage starts from early and middle June to early July.
Rubber rope and palm rope were selected as settling material as they gave better results.In addition, the time to lower the setting rope and the substrata required for the settling of spats are discussed. |
