Abstract

We report two new records of the Atlantic bigeye, Priacanthus arenatus Cuvier, 1829, from Italian waters (Ionian Sea and Strait of Sicily), confirmed through morphological and molecular analyses. The species has previously been reported in the Mediterranean only twice, in the Gulf of Cagliari and the Strait of Messina. Morphometric and meristic data were compared with literature values, and phylogenetic analyses based on COI sequences confirmed species identity and suggested affinity with an eastern Atlantic haplotype. Ecological implications and taxonomic considerations are discussed.

地中海沙棘鱼新记录：具有生物地理学见解的形态学和分子证据

本文报道了意大利爱奥尼亚海和西西里岛海峡大西洋大眼鱼（Priacanthus arenatus Cuvier, 1829）的两个新记录，并通过形态学和分子分析加以证实。该物种以前在地中海只被报道过两次，在卡利亚里湾和墨西拿海峡。形态计量学和分分体分析数据比较了文献值，基于COI序列的系统发育分析证实了物种身份，并表明与东大西洋单倍型有亲缘关系。讨论了生态学意义和分类学考虑。

期刊介绍： Frontiers in Marine Science publishes rigorously peer-reviewed research that advances our understanding of all aspects of the environment, biology, ecosystem functioning and human interactions with the oceans. Field Chief Editor Carlos M. Duarte at King Abdullah University of Science and Technology Thuwal is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, policy makers and the public worldwide. With the human population predicted to reach 9 billion people by 2050, it is clear that traditional land resources will not suffice to meet the demand for food or energy, required to support high-quality livelihoods. As a result, the oceans are emerging as a source of untapped assets, with new innovative industries, such as aquaculture, marine biotechnology, marine energy and deep-sea mining growing rapidly under a new era characterized by rapid growth of a blue, ocean-based economy. The sustainability of the blue economy is closely dependent on our knowledge about how to mitigate the impacts of the multiple pressures on the ocean ecosystem associated with the increased scale and diversification of industry operations in the ocean and global human pressures on the environment. Therefore, Frontiers in Marine Science particularly welcomes the communication of research outcomes addressing ocean-based solutions for the emerging challenges, including improved forecasting and observational capacities, understanding biodiversity and ecosystem problems, locally and globally, effective management strategies to maintain ocean health, and an improved capacity to sustainably derive resources from the oceans.
