摘要

当其他迁徙鲑鱼种群在人类世遭受痛苦时,粉红鲑鱼(Oncorhynchus gorbusca Salmonidae)正在蓬勃发展,它们的分布范围在自然范围内扩大,在20世纪50年代将该物种引入白海后,在大西洋和北极。粉红鲑鱼现在正在欧洲迅速蔓延,甚至越过大洋到达北美。自2017年以来,在整个北大西洋,大量粉红鲑鱼在挪威河流中繁殖,少量个体被捕获。尽管人们对粉红鲑鱼在其新分布地区的生物学和生态学知之甚少,但该物种的引入对本地物种和流域生产力的影响可能非常重要。在大西洋国家,粉红鲑鱼正在鱼类动物群中巩固自己的地位,对本地鱼类群落构成潜在威胁,在本地和扩展范围内的粉红鲑鱼的对比将是导航管理策略的关键。本文的一个关键结论是,物种的可遗传性状是快速选择的,并推动了局部适应和进化。在大西洋地区,这可能有助于进一步建立和传播。粉红鲑鱼在大西洋盆地的入侵最终是一个大规模的生态实验,也是北大西洋主要动物变化的第一个例子之一,由于其他人为压力因素,北大西洋已经在经历快速变化。迫切需要新的研究来了解粉红鲑鱼在大西洋生态系统中的作用和潜在的未来影响。

Prospects for the future of pink salmon in three oceans: From the native Pacific to the novel Arctic and Atlantic

While populations of other migratory salmonids suffer in the Anthropocene, pink salmon (Oncorhynchus gorbusca Salmonidae) are thriving, and their distribution is expanding both within their natural range and in the Atlantic and Arctic following introduction of the species to the White Sea in the 1950s. Pink salmon are now rapidly spreading in Europe and even across the ocean to North America. Large numbers of pink salmon breed in Norwegian rivers and small numbers of individuals have been captured throughout the North Atlantic since 2017. Although little is known about the biology and ecology of the pink salmon in its novel distribution, the impacts of the species' introduction are potentially highly significant for native species and watershed productivity. Contrasts between pink salmon in the native and extended ranges will be key to navigating management strategies for Atlantic nations where the pink salmon is entrenching itself among the fish fauna, posing potential threats to native fish communities. One key conclusion of this paper is that the species' heritable traits are rapidly selected and drive local adaptation and evolution. Within the Atlantic region, this may facilitate further establishment and spread. The invasion of pink salmon in the Atlantic basin is ultimately a massive ecological experiment and one of the first examples of a major faunal change in the North Atlantic Ocean that is already undergoing rapid changes due to other anthropogenic stressors. New research is urgently needed to understand the role and potential future impacts of pink salmon in Atlantic ecosystems.

期刊介绍: Fish and Fisheries adopts a broad, interdisciplinary approach to the subject of fish biology and fisheries. It draws contributions in the form of major synoptic papers and syntheses or meta-analyses that lay out new approaches, re-examine existing findings, methods or theory, and discuss papers and commentaries from diverse areas. Focal areas include fish palaeontology, molecular biology and ecology, genetics, biochemistry, physiology, ecology, behaviour, evolutionary studies, conservation, assessment, population dynamics, mathematical modelling, ecosystem analysis and the social, economic and policy aspects of fisheries where they are grounded in a scientific approach. A paper in Fish and Fisheries must draw upon all key elements of the existing literature on a topic, normally have a broad geographic and/or taxonomic scope, and provide general points which make it compelling to a wide range of readers whatever their geographical location. So, in short, we aim to publish articles that make syntheses of old or synoptic, long-term or spatially widespread data, introduce or consolidate fresh concepts or theory, or, in the Ghoti section, briefly justify preliminary, new synoptic ideas. Please note that authors of submissions not meeting this mandate will be directed to the appropriate primary literature.
