摘要
对初步建成的《养殖水域温盐信息系统》进行试验开发,分析了海湾扇贝南移至万山水域养成的可行性。根据万山湾18a每日的温盐信息,通过平均值、距平值、极限值等多项统计特性的分析,认为珠江口水域只有10月至翌年4月基本具备养成海湾扇贝的温盐自然条件,盐度20~35;温度18~28℃。而每年6~8月该水域都会受高温、低盐的袭击,盐度极端低值曾出现2.39、3.06、4.80等,在这样的盐度条件下,会导致海湾扇贝养殖成体全部死亡。因此,本着因地制宜的方针,作者认为该水域不宜发展海湾扇贝养殖。
For a feasibility study for bay scallop farming in Wanshan Bay waters, 18 a data of temperature and salinity from the marine observing stations around Wanshan Islands have beenanalyzed. The characteristics of temperature and salinity in the waters were obtained by thestatistical analyses of the means, the mean anomalies as well as the minimums. The resultsshow that the conditions of temperature and salinity needed by the bay scallop growth onlyappears in the period from October to April in the waters of Zhujiang Mouth. When watertemperature is 18~ 28℃ and salinities 20~35. The period from June to October has hightemperature and low salinity when salinity used to drop to as low as 2. 39, 3. 06 and 4. 80.Under this salinity, scallops may not survive. It is concluded that the Wanshan waters is notsuitable for the development of bay scallop culture.
