波纹巴非蛤生物学性状及生态习性的初步观察

引进福建增殖海区采捕的波纹巴非蛤,共取样271颗个体,对其壳长、壳宽、壳高、体重、软组织湿重等进行了测定分析。同时在人控环境条件下,对其生态习性进行了初步观察。结果表明:波纹巴非蛤外型为平扁椭圆形,长度约为高度的2.9倍,长度约为宽度的1.7倍,其壳长、壳宽、壳高、体重、鲜肉重间都存在着线性相关;波纹巴非蛤适栖养于泥砂介质,其干露、湿露状态下的半致死时间分别出现在36～40 h和52～58 h,该蛤对酸碱度的变化不敏感,其盐度适应范围是24～36,其中以30～32为最适。

A Preliminary Observation on Biological and Ecological Characteristics of Paphia undulate (Born)

271 individuals of Paphia undulate were choosed from coastal area of Fujian Province,and their shell length,width,height,body and soft weight were measured.Meanwhile,ecology of the species also was preliminary investigated under artificially controlled culture condiotion.Results showed that the shape of Paphia undulate was flat oval and its shell longth was about 2.9 times of height and about 1.7 times of width.There were line correlations among data of shell length,width,height,weight and soft weight;The best sediment for Paphia undulate culture was arenaceous;The semi-lethal time was 36~40 h in air exposure and 52~58 h in wet exposure.It was less susceptive to acid alkalinity and the scope of living salinity was 24~36,and the best living salinity was 30~32.
