秦皇岛潮间带巴西沙蠋生殖期特征研究

Reproductive Characteristics of Arenicola Brasiliensis in the Intertidal Zone of Qinhuangdao

巴西沙蠋是潮间带生态学领域的一种重要研究对象,根据2019和2020年对秦皇岛近岸海域潮间带底栖生物调查结果显示,7月底至8月中旬是巴西沙蠋生殖盛期,分布于秦皇岛的海港和北戴河沿海潮间带。虫体横道深浅与虫体生物学特性、底质沙粒大小、底质中食物含量、底质含水率、底质温度和底质气体状况等有关。这是首次对秦皇岛近岸海域潮间带巴西沙蠋进行全面调查研究,研究结果为探讨该海域巴西沙蠋生活史和综合开发利用研究提供了参考资料。

Arenicola brasiliensis is an important research object in the field of intertidal ecology.The results of the survey of benthic organisms in the intertidal zone of Qinhuangdao in 2019 and 2020 showed that the period from the end of July to the middle of August is the peak reproductive stage of Arenicola brasiliensis,which is distributed in the harbour of Qinhuangdao and intertidal zones of Beidaihe.The depth of living worms is related to the biological characteristics of the worms,the size of the sediment particles,the food and water content of the sediments,the temperature of the sediments and the gas condition of the sediments.This is the first comprehensive investigation and study of Arenicola brasiliensis in the intertidal zone of Qinhuangdao.The results provide references for research of the life history and comprehensive development and utilization of Arenicola brasiliensis in the sea area.
