Three species of snappers from artisanal, small-scale fisheries were examined for the presence of parasites. A total of 139 lutjanid fish were collected: 69 specimens of Lutjanus analis, 47 specimens of Lutjanus vivanus, and 23 specimens of Lutjanus synagris. Encysted plerocercoid of trypanorhynch cestodes found at necropsy in the viscera of snappers were sampled for parasitological analysis. These plerocercoid larvae belong to the genera Floriceps, Pseudogrillotia , and Oncomegas. Although these parasites do not have any zoonotic potential, fish with heavy loads of plerocercoids are rejected during inspection as they compromise meat hygiene. Our findings suggest that light larval cestode infections in lutjanids would not lead to consumer rejection of the food product. The occurrence of Floriceps sp. in L. analis and in L. synagris, of Pseudogrillotia sp. in L. vivanus and in L. synagris , and of Oncomegas sp. in L. synagris are new findings in these fish species. These parasites are new to these fish species and have not been reported in snappers from the northeast coast of Brazil. The results contribute to the existing body of knowledge about the parasitic fauna of fish and its distribution along the coastline of Brazil.
对来自个体小规模渔业的三种笛鲷进行了寄生虫检查。共采集了139条笛鲷科鱼类:69条臀斑笛鲷标本、47条黄尾笛鲷标本和23条合齿笛鲷标本。在笛鲷内脏尸检时发现的三锥吻绦虫的包囊裂头蚴被取样进行寄生虫学分析。这些裂头蚴幼虫属于弗洛里裂头绦虫属、拟裸头绦虫属和巨头绦虫属。虽然这些寄生虫没有任何人畜共患病的潜在风险,但带有大量裂头蚴的鱼在检查时会被拒收,因为它们会影响肉类卫生。我们的研究结果表明,笛鲷科鱼类中轻度的绦虫幼虫感染不会导致食品被消费者拒收。弗洛里裂头绦虫属在臀斑笛鲷和合齿笛鲷中的出现、拟裸头绦虫属在黄尾笛鲷和合齿笛鲷中的出现以及巨头绦虫属在合齿笛鲷中的出现,在这些鱼类物种中都是新发现。这些寄生虫对于这些鱼类物种来说是新的,在巴西东北海岸的笛鲷中尚未有报道。这些结果有助于丰富关于鱼类寄生动物群及其在巴西海岸线分布的现有知识体系。
