The lionfish, Pterois miles, is one of the most recent Lessepsian immigrants into the Mediterranean Sea and it poses a serious threat to marine ecosystems in the region. This study assesses the basic biology and ecology of lionfish in the Mediterranean, examining morphometrics, reproduction and diet as well as population structure and distribution. The population density of lionfish increased dramatically in Cyprus since the first sighting in late 2012; by 2018 aggregations of up to 70 lionfish are found on rocky grounds with complex relief and artificial reefs in depths of 0-50 m. Lionfish in Cyprus become mature within a year and adults are spawning capable year-round, with peak spawning in summer when the sea surface temperature reaches 28.4 °C. The Cypriot lionfish grow faster and bigger than in their native range, and females are more common than males. Lionfish are generalist predators in these waters, as also found in their native range, consuming a range of teleost and crustacean prey, some of which are of high economic value (e.g. Spicara smaris and Sparisoma cretense) or have an important role in local trophic webs (e.g. Chromis chromis). Overall, the reproductive patterns, the presence of juveniles and adults throughout the year, the rapid growth rates and the generalist diet indicate that lionfish are thriving and are now already well established in the region and could potentially become the serious nuisance that they are in their temperate and tropical western Atlantic invasive range.

他们留在这里:地中海狮子鱼(Pteroismiles)的生物学和生态学

狮子鱼,Pterois miles,是最近进入地中海的莱塞普斯移民之一,它对该地区的海洋生态系统构成了严重威胁。这项研究评估了地中海狮子鱼的基本生物学和生态学,检查了形态测量学、繁殖和饮食以及种群结构和分布。自 2012 年底首次发现狮子鱼以来,塞浦路斯的狮子鱼种群密度急剧增加;到 2018 年,在 0-50 m 深度具有复杂地形和人工鱼礁的岩石地面上发现了多达 70 条狮子鱼。塞浦路斯的狮子鱼在一年内成熟,成年狮子鱼全年都能产卵,夏季海面温度达到 28.4 °C 时产卵高峰期。塞浦路斯狮子​​鱼比它们的原生地生长得更快更大,女性比男性更常见。狮子鱼是这些水域中的多面手捕食者,在它们的原生范围内也有发现,捕食一系列硬骨和甲壳类猎物,其中一些具有很高的经济价值(例如 Spicara smaris 和 Sparisoma cretense)或在当地的营养网中发挥重要作用(例如 Chromis chromis)。总体而言,繁殖模式、全年幼鱼和成鱼的存在、快速的增长率和多面手的饮食表明狮子鱼正在蓬勃发展,现在已经在该地区成熟,并有可能成为它们生活中的严重滋扰。温带和热带西大西洋入侵范围。本文受版权保护。版权所有。食用一系列硬骨和甲壳类猎物,其中一些具有很高的经济价值(例如 Spicara smaris 和 Sparisoma cretense)或在当地的营养网中具有重要作用(例如 Chromis chromis)。总体而言,繁殖模式、全年幼鱼和成鱼的存在、快速的增长率和多面手的饮食表明狮子鱼正在蓬勃发展,现在已经在该地区成熟,并有可能成为它们生活中的严重滋扰。温带和热带西大西洋入侵范围。本文受版权保护。版权所有。食用一系列硬骨和甲壳类猎物,其中一些具有很高的经济价值(例如 Spicara smaris 和 Sparisoma cretense)或在当地的营养网中具有重要作用(例如 Chromis chromis)。总体而言,繁殖模式、全年幼鱼和成鱼的存在、快速的增长率和多面手的饮食表明狮子鱼正在蓬勃发展,现在已经在该地区成熟,并有可能成为它们生活中的严重滋扰。温带和热带西大西洋入侵范围。本文受版权保护。版权所有。繁殖模式、全年都有幼鱼和成鱼、快速的增长率和多面手的饮食表明狮子鱼正在茁壮成长,现在已经在该地区扎根,并有可能成为它们在温带和环境中的严重滋扰。热带西大西洋入侵范围。本文受版权保护。版权所有。繁殖模式、全年都有幼鱼和成鱼、快速的增长率和多面手的饮食表明狮子鱼正在茁壮成长,现在已经在该地区扎根,并有可能成为它们在温带和环境中的严重滋扰。热带西大西洋入侵范围。本文受版权保护。版权所有。
