Helminths from Dormitator maculatus (Pisces: Eleotridae) in Alvarado Lagoon, Veracruz, Mexico, and Supplemental Data for Clinostomum complanatum Rudolphi, 1814 from Egretta caerulea (Aves: Ardeidae)

Abstract

Fishes are important hosts of helminths with aquatic life stages, yet little information is available on host-parasite relationships in tropical low salinity ecosystems. In this paper we report helminth parasites of the fat sleeper, Dormitator maculatus, in the Alvarado lagoon system, Veracruz. Mexico. Four parasite species were recorded from D. maculatus, including trematode metacercariae of Clinostomum complanatum, as well as nematode larvae of Spyroxis sp. and Camallanus sp. and adults of Neochinorhynchus golvani. In addition, we obtained adult C. complanatum from the esophagus of the little blue heron, Egretta caerulea. Dormitator maculatus is a new host for all helminth species reported, and the Alvarado lagoonal system is a new location for these parasite relationships. The prevelance of the 2 most commonly occurring parasites, C. complanatum and N. golvani, was high throughout the year (> 60% and > 43%, respectively). Intensity of infection was highest for C. complanatum in May (92 worms/host) and for N. golvani in October 1993 (33.8 worms/host). The trophic position and habits of D. maculatus contributes to recruitment of trematode and nematode larval stages.

A checklist of metazoan parasites of fish from Tres Palos Lagoon, Guerrero, Mexico

“…Most of the species of parasite identified in this paper (32 species), have been previously reported in the same or different host species from other geographical areas in Mexico (Salgado-Maldonado 1976;Pineda-López et al 1985Pineda-López 1994;Lamothe-Argumedo et al 1997;Moravec 1998;Pérez-Ponce de León et al 1999;Scholz et al 1999Salgado-Maldonado 2000, 2001;Salgado-Maldonado et al 2001a, b, 2004a, b, 2005aVidal-Martinez et al 2001;Montoya-Mendoza et al 2004;Caspeta-Mandujano 2005;SalgadoMaldonado 2006). Thirty-two of the 39 species of parasite are first geographical host records for Tres Palos Lagoon, Guerrero, Mexico (Table 1).…”

Metazoan parasite communities of three endemic cichlid fish species from the upper Grijalva River, Chiapas, Mexico

“…The parasite fauna of the three species of cichlids from the upper GRB is composed of 18 taxa, all of them have been previously reported in other cichlids from Southeastern Mexico (Campeche, Chiapas, Oaxaca, Quintana Roo, Tabasco, Veracruz and Yucatan) (Salgado-Maldonado et al, 1997Vidal-Martínez et al, 2001;Violante-González & Aguirre-Macedo, 2007;Violante-González et al, 2008a;Salgado-Maldonado, 2008, 2011, 2016 and in other fish families (Atherinidae, Clupleidae, Eleotridae, Goodeidae, Mugilidae, Pimelodidae and Profundulidae) (Montoya-Mendoza et al, 2004;Salgado-Maldonado et al, 2005;Martínez-Aquino et al, 2014;Pinacho-Pinacho, 2015). Despite this fact, almost all parasites reported herein represent new host and geographical records probably due to hosts have been poorly parasitologically studied or not studied at all (e.g.…”
