摘要
舟山水域的三角藤壶Balanus trigonus Darwin对基物无明显的选择性。它主要分布在远岸盐度大于30的水域,风浪作用较小的湾(天山)处数量最大。在垂向上,以15～20m水层数量最大。种群结构因时间、地点而异。枸杞的三角藤壶在污损生物群落中占有重要地位,夏季沿岸区的生物量占污损生物生物总量的98.2％。本季,特别是7、8月份是三角藤壶防除的关键时期。本文还讨论了三角藤壶种群的生长参数和死亡率及其与环境因素的关系。
Balanus trigonus Darwin in Zhoushan waters doesn' t show obvious selectivity to its base substance. It mainly distributes in waters off coast with salinity more than 30 and the largest amount appears in estuaries less affected by wave function. In 0-20 m water layer, the largest amount appears in 15-20 m water layer. The population structures vary with time and site.B. trigonus occupies an important place in fouling organisms community in Gouqi water, and the biomass along the coast in summer accounts for 98.2% of the total biomass of fouling organisms. Summer, especially July and August, is a key period to prevent B. trigonus. In this paper, the growth parameter and the death rate of B. trigonus population and their relation to environment factors are also discussed.
