迄今为止，将底栖无脊椎动物的群落结构与鱼类摄食联系起来的研究很少，而且这种摄食选择性背后的因素也鲜为人知。在这项研究中，我们将无脊椎动物物种组成、优势结构和鱼类生物学特征与波罗的海穆加湾本地比目鱼、鲈鱼和入侵圆虾虎鱼的摄食选择性和重叠联系起来。鱼类饮食中底栖无脊椎动物的物种组成和比例与现场现有的不同。除了圆形虾虎鱼外，所研究的鱼类更喜欢小型且活动的无脊椎动物，而不是大型双壳类。然而，所研究的物种，即圆虾虎鱼和比目鱼的饮食是重叠的。此外，鲈鱼捕食圆虾虎鱼的幼龄阶段，这表明圆虾虎鱼的引入可能会对比目鱼产生负面影响，但会对鲈鱼产生积极影响。
To date the studies that link community structure of benthic invertebrates with fish feeding are rare as well as factors that are behind this feeding selectivity are poorly known. In this study, we related invertebrate species composition, their dominance structure and fish biological characteristics to the feeding selectivity and overlap of the native flounder, perch and the invasive round goby in Muuga Bay, the Baltic Sea. Species composition and proportion of benthic invertebrates in the diet of fishes differed from what was available in the field. Except for the round goby, the studied fishes preferred small and mobile invertebrates over large bivalves. However, diet of the studied species, namely the round goby and flounder overlapped. Besides, perch preyed on young stages of the round goby indicating that the introduction of round goby may negatively affect flounder but positively perch.
