Abstract

The yellowfin, Thunnus albacares (Bonaterre), is one of the most important resources for commercial fisheries along the Mexican Pacific coast. The parasite fauna of this important marine resource has been documented in different regions across its global distributional range. However, few studies have been conducted on parasites of tuna populations in the Cortezian Marine Ecoregion (CME) in northwestern Mexico, despite the development of the fresh and frozen sushi/sashimi-grade tuna market in recent decades. Our study aimed at identifying the metazoan parasite fauna of T. albacares in the CME. Between 2023 and 2024, 17 individuals were studied for parasites before being processed. Parasites were collected and identified using morphological and molecular data. One hundred twenty-five metazoan parasites were collected, representing 10 species, including the monogeneans Hexostoma thynni (Delaroche, 1811) Rafinesque, 1815, Neobenedenia girellae (Hargis, 1955) Yamaguti, 1963, and Capsala sp., the digenean Hirudinella ahi (Pallas, 1774) Baird, 1853, the larval cestode Heterosphyriocephalus tergestinus (Pintner, 1913) Dallarés, Carrassón and Schaeffner, 2016, larval forms of the nematode Anisakis typica (Diesing, 1860) Baylis, 1920, the acanthocephalan Rhadinorhynchus laterospinosus Amin, Heckmann, and Ha, 2011, and three species of copepods, Euryphorus brachypterus (Gerstaecker, 1853), Pseudocycnus appendiculatus Heller, 1865 and Brachiella thynni Cuvier, 1830. Anisakis typica reached the highest prevalence of infection in our samples, and along with R. laterospinosus, it reached the highest mean intensity values. This study reports a species that represents a zoonotic risk (A. typica) and contributes to the understanding of the parasite diversity of commercially important fish in the CME.

墨西哥西北部锡那罗亚海岸黄鳍金枪鱼,Thunnus albacares (Bonnaterre, 1788) (Scombridae)的后生寄生虫区系鉴定。
黄鳍金枪鱼(Thunnus albacares, Bonaterre)是墨西哥太平洋沿岸商业渔业最重要的资源之一。这一重要海洋资源的寄生动物群已在其全球分布范围的不同地区得到记录。然而,尽管近几十年来新鲜和冷冻寿司/生鱼片级金枪鱼市场的发展,但对墨西哥西北部Cortezian海洋生态区(CME)金枪鱼种群寄生虫的研究很少。本研究的目的是鉴定白背绦虫在CME中的后生寄生虫区系。在2023年至2024年期间,在处理之前对17个人进行了寄生虫研究。收集寄生虫并利用形态和分子资料进行鉴定。共收集到10种后生动物寄生虫125种,包括单系Hexostoma thynni (Delaroche, 1811) Rafinesque (1815), neobenenia girellae (Hargis, 1955) Yamaguti(1963)和Capsala sp., digenean Hirudinella ahi (Pallas, 1774) Baird(1853),寄生蜂Heterosphyriocephalus tergestinus (Pintner, 1913) dallars (Carrassón)和Schaeffner(2016),寄生蜂Anisakis typica (Diesing, 1860),寄生蜂Baylis(1920),寄生蜂和寄生蜂等。棘头动物Rhadinorhynchus laterospinosus Amin, Heckmann, and Ha, 2011,桡足动物Euryphorus brachypterus (Gerstaecker, 1853)、pseudoycnus appendiculatus Heller, 1865和Brachiella thynni Cuvier, 1830。典型异尖基斯虫感染率最高,与后棘棘鼠一起达到最高的平均强度值。本研究报告了一种具有人畜共患风险的物种(典型亚种),并有助于了解CME商业重要鱼类的寄生虫多样性。

期刊介绍: Journal of Helminthology publishes original papers and review articles on all aspects of pure and applied helminthology, particularly those helminth parasites of environmental health, medical or veterinary importance. Research papers on helminths in wildlife hosts, including plant and insect parasites, are also published along with taxonomic papers contributing to the systematics of a group. The journal will be of interest to academics and researchers involved in the fields of human and veterinary parasitology, public health, microbiology, ecology and biochemistry.
