The species composition of epibiotic communities on red king crab was investigated in Sayda Bay, Russia, during November of 2015 and 2016. The community consisted of 12 species in total. Among epibionts, the barnacle was most prevalent (67.0%), while the amphipod was the most frequent symbiont (77.3%). Infestation levels in May-June 2005 and September 2004 were higher, as a larger proportion of small crabs without fouling species were present during those seasons. The lower infestation intensities recorded for other common associated organisms during winter can be attributed to their increased mortality due to unfavorable temperature conditions. The localization of epibionts and symbionts were related to larval settlement patterns of attached species and feeding behavior of mobile species. Monthly growth increments for and were estimated at 2 mm in body length and 1.35 mm in basal diameter, respectively. Size-at-age data for epibionts can aid in the age determination of large male crabs that may skip an annual molt.
2015年11月和2016年11月，在俄罗斯的赛达湾对红帝王蟹体表生物群落的物种组成进行了调查。该群落共有12个物种。在体表生物中，藤壶最为常见（67.0%），而端足类动物是最常见的共生生物（77.3%）。2005年5 - 6月和2004年9月的附着水平较高，因为在这些季节存在较大比例没有附着生物的小螃蟹。冬季其他常见伴生生物的附着强度较低，这可能是由于不利的温度条件导致它们死亡率增加。体表生物和共生生物的分布位置与附着物种的幼体附着模式以及活动物种的摄食行为有关。估计藤壶和[此处原文缺失一种生物名称]的体长每月增长分别为2毫米，基部直径每月增长1.35毫米。体表生物的年龄 - 大小数据有助于确定可能跳过年度蜕壳的大型雄蟹的年龄。
