摘要

硬头鲶(Ariopsis felis)是墨西哥湾北部两种鲶科鱼类之一,也是该地区沿海水域最常见的鱼类之一。作为一种具有独特繁殖生活史的普通消费者,墨西哥湾西部的长期种群动态信息有限,本研究的目标是利用独立于渔业的长期数据集和从属数据集评估得克萨斯州河口的趋势,并对这些河口的幼年硬头鲶和成年硬头鲶的栖息地适宜性进行分析。从 20 世纪 90 年代中期和 21 世纪初开始,一些河口的硬头鲶成鱼单位渔获量(CPUE)呈下降趋势,此外,在中部和下海岸河口还观察到成鱼平均长度普遍下降的趋势。与大型群落中的鳍鱼 CPUE 相比,硬头鲶成鱼在德克萨斯州大多数河口的相对贡献(以 CPUE 百分比表示)呈下降趋势。如果将硬头鲶与较大的鲷科鱼种群结合起来,并与普通鲷科鱼种群的相对贡献率进行比较,通常会发现在许多河口,这两个鱼种群的贡献率正在趋同。这主要表现为胭脂鱼科的增加趋势。鉴于鲶科鱼类的营养作用,它们显然有可能对河口食物网产生重大营养影响。我们的研究强调了长期监测和研究非鲶鱼物种在更大范围内评估群落随时间变化的价值。

Trends and distribution of hardhead catfish in Texas estuaries—shifting relative abundance of a highly ubiquitous generalist predator

Trends and distribution of hardhead catfish in Texas estuaries—shifting relative abundance of a highly ubiquitous generalist predator

Hardhead catfish (Ariopsis felis) are one of two Ariidae catfishes in the northern Gulf of Mexico and are one of the most common fishes found in the coastal waters in this region. As a generalist consumer with a unique reproductive life history and limited information on long-term population dynamics in the Western Gulf of Mexico, the objectives of this study were to assess trends in Texas estuaries using long-term fishery independent and dependent data sets and to conduct habitat suitability analyses in these same estuaries for both young-of-the-year and adult hardhead catfish. Some estuaries have experienced decreasing trends in catch-per-unit-effort (CPUE) of adult hardhead catfish beginning in the mid-1990s and early 2000s, and widespread decreasing trends in adult mean length were additionally observed for central and lower coast estuaries. Compared to the CPUE of finfish in the larger community, adult hardhead catfish largely exhibited decreasing trends in their relative contribution (expressed as percentage of CPUE) across most Texas estuaries. When combined with the larger Ariidae species grouping, and compared to the relative contribution of common Sciaenids, it was generally observed that the contributions of these two species groupings were converging for many estuaries. This was primarily characterized by increasing Ariidae trends. Given the trophic role of Ariidae catfishes, they clearly have the potential to exert major trophic influence on estuarine food webs. Our study highlights the value of long-term monitoring and the study of non-gamefish species in the larger assessment of community change across time.

期刊介绍: Environmental Biology of Fishes is an international journal that publishes original studies on the ecology, life history, epigenetics, behavior, physiology, morphology, systematics and evolution of marine and freshwater fishes. Empirical and theoretical papers are published that deal with the relationship between fishes and their external and internal environment, whether natural or unnatural. The journal concentrates on papers that advance the scholarly understanding of life and draw on a variety of disciplines in reaching this understanding. Environmental Biology of Fishes publishes original papers, review papers, brief communications, editorials, book reviews and special issues. Descriptions and submission requirements of these article types can be found in the Instructions for Authors.
