Abstract

Abstract The rare in the German North and Baltic Sea waters and strictly protected sea star Crossaster papposus was found in 2019 and 2021 during monitoring activities in a marine protected area. This unique observation was achieved by using towed camera platform imagery along a transect in the Fehmarn Belt, which allows monitoring of a much larger area of the seafloor compared to traditional invasive grab and dredge sampling. The last time C. papposus was documented in this area was in 1871, indicating the rarity of this species in the Baltic Sea. Possible explanations for such rare records of the occurrence of this presumably native species in the study region are briefly discussed, including uncommon survival due to salinity conditions caused by prior inflows of saline water from the North Sea.

100多年来在波罗的海首次记录到共同的太阳星帕波索斯十字星（L.，1767）

摘要2019年和2021年，在一个海洋保护区的监测活动中，在德国北海和波罗的海水域发现了这种罕见的、受到严格保护的海星帕波斯十字星。这一独特的观测是通过使用沿费曼带横断面的拖曳式摄像机平台图像实现的，与传统的侵入式抓斗和挖泥船采样相比，这可以监测更大的海底区域。上一次在该地区记录到C.papposus是在1871年，这表明该物种在波罗的海很罕见。简要讨论了这种可能是本地物种在研究区域出现的罕见记录的可能解释，包括由于之前北海盐水流入造成的盐度条件而导致的罕见存活。
