Abstract

The ide Leuciscus idus is a large-bodied cyprinid native to freshwaters around the Baltic, Black, Caspian, White, Barents, Kara, Laptev and North seas as well as the Aral Sea region. Historically an important commercial species, the ide is used in recreational fisheries and as an ornamental fish, and is subject to translocation and stocking events. The ide is less well-studied than many European cyprinids and relatively little is known of the risks it poses to native species and ecosystems where introduced. The present review and meta-analysis examine available data on the ide’s environmental biology to provide an assessment of its potential invasiveness. A long-lived, omnivorous species, the ide is a habitat generalist that inhabits lowland rivers and nutrient-rich lakes, but also some brackish waters where it is facultatively anadromous. The ide displays variable age and length at maturity and asymptotic growth in body length, can be highly productive and migratory, and can withstand variable environmental conditions. Despite several attributes that should facilitate acclimation to novel environments, the ide has established relatively few self-sustaining populations outside its native range, and is therefore not currently considered to be invasive. However, as introductions are likely to continue, increased propagule pressure could lead to the development of invasive non-native populations in some locations.

摘要

IDE的雅罗鱼是大型的塞浦路斯鲤鱼，原产于波罗的海，黑海，里海，白海，巴伦支，卡拉，拉普捷夫和北海以及咸海地区附近的淡水。在历史上是重要的商业物种，该ide用于休闲渔业和观赏鱼，易受易位和放养事件的影响。与许多欧洲鲤科鱼类相比，该思想的研究程度较低，而且对引入该物种对当地物种和生态系统构成的风险知之甚少。本综述和荟萃分析检查了有关ide的环境生物学的可用数据，以评估其潜在的侵袭性。ide是一种长寿的杂食性物种，是栖息地的通才，居住在低地河流和营养丰富的湖泊，以及一些咸淡的水域中，这些水是兼性的。该ide在成熟时显示出可变的年龄和长度，并且在体长上渐近生长，可以高产和迁徙，并且可以承受各种环境条件。尽管有几个属性应该有助于适应新的环境，但该想法在其自然范围之外建立了相对较少的自我维持种群，因此目前不被认为是侵入性的。但是，由于可能会继续进行引进，因此繁殖压力的增加可能导致某些地方的非本地侵入性种群的发展。这个想法已经在其自然范围之外建立了相对较少的自我维持群体，因此目前不被认为是侵入性的。但是，由于可能继续进行引进，因此繁殖压力的增加可能导致某些地方的非本地侵入性种群的发展。这个想法已经在其自然范围之外建立了相对较少的自我维持群体，因此目前不被认为是侵入性的。但是，由于可能会继续进行引进，因此繁殖压力的增加可能导致某些地方的非本地侵入性种群的发展。
