Abstract

Bryozoans are major fouling organisms and include some of the most invasive marine species globally. Hull fouling of transoceanic vessels is a major vector of non-indigenous bryozoans. One genus known to be important in this regard is Conopeum, but its occurrence in the coastal waters of South Korea has yet to be established. We sorted bryozoan samples from the collection of Park et al. (2017) and carried out surveys for marine organisms in 2013 and 2019–2020 in coastal waters of South Korea. We found two non-indigenous bryozoans: Conopeum reticulum (Linnaeus, 1767) and C. seurati (Canu, 1928). These two species and a third in the genus, C. hexagonum Seo, 1996, have distinctive morphologies and distributions along environmental gradients of the sampling sites. Gymnocyst and cryptocyst development and spine presence were used to identify each species morphologically. According to the salinity and turbidity of the sites, the inhabiting species appeared differently. The two nonindigenous species occurred in association with other sessile organisms such as oysters, mussels, and serpulid polychaetes. In particular, C. reticulum was associated with an invasive species of the Mediterranean mussel (Mytilus galloprovincialis Lamarck, 1819) and C. seurati was associated with the serpulid polychaetes Hydroides ezoensis Okuda, 1934 and Ficopomatus enigmaticus (Fauvel, 1923), as well as with the mytilid bivalve Xenostrobus securis (Lamarck, 1819), and the Pacific oyster Crassostrea gigas (Thunberg, 1793). Conopeum seurati and H. ezoensis completely encrusted all surfaces in artificial canal docks seemingly negatively affecting richness of native species.
韩国沿海水域两种非本地Conopeum(苔藓虫纲:Cheilostomata)的发生
苔藓虫是主要的污染生物,包括一些全球最具侵略性的海洋物种。越洋船舶的船体污垢是非本地苔藓虫的主要载体。已知在这方面很重要的一个属是Conopeum,但它在韩国沿海水域的分布情况尚未确定。我们对Park等人(2017)收集的苔藓虫样本进行了分类,并于2013年和2019-2020年在韩国沿海水域对海洋生物进行了调查。我们发现了两种非本地苔藓虫:Conopeum reticulum (Linnaeus, 1767)和C. seurati (Canu, 1928)。这两个种和第三个属(C. hexonum Seo, 1996)在采样点的环境梯度上有不同的形态和分布。裸子囊肿和隐囊肿的发育和脊柱的存在被用来识别每个物种的形态。根据测点的盐度和浊度不同,栖息物种的形态也不同。这两种非本地物种与其他无根生物如牡蛎、贻贝和绢壳多毛类一起出现。特别是,C. reticulum与地中海贻贝的一种入侵物种(Mytilus galloprovincialis Lamarck, 1819)有关,C. seurati与serpulid polychaetes hydrozoensis Okuda, 1934, Ficopomatus enigmaticus (Fauvel, 1923),以及myliid bivalve Xenostrobus securis (Lamarck, 1819)和Pacific oyster Crassostrea gigas (Thunberg, 1793)有关。人工运河码头的所有表面都被康柏(conopum seurati)和埃佐马(H. ezoensis)完全包裹,似乎对本地物种的丰富度产生了负面影响。

期刊介绍: Aquatic Invasions is an open access, peer-reviewed international journal focusing on academic research of biological invasions in both inland and coastal water ecosystems from around the world. It was established in 2006 as initiative of the International Society of Limnology (SIL) Working Group on Aquatic Invasive Species (WGAIS) with start-up funding from the European Commission Sixth Framework Programme for Research and Technological Development Integrated Project ALARM. Aquatic Invasions is an official journal of International Association for Open Knowledge on Invasive Alien Species (INVASIVESNET). Aquatic Invasions provides a forum for professionals involved in research of aquatic non-native species, including a focus on the following: • Patterns of non-native species dispersal, including range extensions with global change • Trends in new introductions and establishment of non-native species • Population dynamics of non-native species • Ecological and evolutionary impacts of non-native species • Behaviour of invasive and associated native species in invaded areas • Prediction of new invasions • Advances in non-native species identification and taxonomy
