Currently, there is little comparative data on ‘efficiency’ of different engineering species, i.e. species richness, density and biomass of the associated organisms that have been supported by engineering species. The use of fouling communities makes it possible to compare the efficiency of different engineering species under the same conditions, which is necessary to obtain correct estimates and difficult to do when studying natural bottom communities. In this study, we have analysed the fouling communities in four different mussel culture farms in the White Sea to test the following hypotheses. (1) Different engineering species (mussel Mytilus edulis, solitary ascidian Styela rustica, sponge Halichondria panicea) have different assemblages of the associated vagile fauna. (2) Mytilus edulis is the most efficient engineering species, i.e. species richness, species diversity, density and biomass of the associated vagile fauna is higher in the mussel communities than in those dominated by Styela rustica or Halichondria panicea. The first hypothesis was confirmed, while the second was rejected. In all the culture farms studied, all parameters of the mussel-associated vagile fauna were not higher and in most cases were even lower than those of the fauna associated with ascidians or sponges. The reason for this seems to be the very dense packing of mussels in patches. Therefore, Mytilus edulis is not the most efficient engineering species among fouling organisms, at least in the conditions of the subarctic White Sea. The data obtained are particularly important in view of the ever-increasing volume of anthropogenic substrate and fouling communities in coastal marine ecosystems.

贻贝作为工程物种在白海人工结构上的浅水污染群落的比较效率

目前，关于不同工程物种的“效率”的比较数据很少，即工程物种支持的相关生物的物种丰富度、密度和生物量。污染群落的使用使得在相同条件下比较不同工程物种的效率成为可能，这是获得正确估计所必需的，在研究自然底层群落时很难做到。在这项研究中，我们分析了白海四个不同贻贝养殖场的污染群落，以检验以下假设。(1) 不同的工程物种（贻贝贻贝, 孤独的海鞘黄花鱼， 海绵苦瓜) 具有相关的可变动物群的不同组合。(2)贻贝是最有效的工程物种，即相关的可变动物群的物种丰富度、物种多样性、密度和生物量在贻贝群落中高于以贻贝为主的群落。黄花鱼要么苦瓜. 第一个假设被证实，而第二个假设被拒绝。在所研究的所有养殖场中，与贻贝相关的可变动物群的所有参数并不高，在大多数情况下甚至低于与海鞘或海绵相关的动物群的参数。造成这种情况的原因似乎是贻贝非常密集地堆积成片。所以，贻贝至少在亚北极白海的条件下，它不是污染生物中最有效的工程物种。鉴于沿海海洋生态系统中人为基质和污染群落的数量不断增加，所获得的数据尤其重要。
