Leopoldina Aguirre-Macedo & Edgar F. Mendoza-Franco Received: 13 April 2007 /Accepted: 15 August 2007 # Springer-Verlag 2007 Abstract An extensive survey of helminth parasites in fish Introduction species from Tres Palos Lagoon, in Guerrero, Mexico, resulted in identification of 39 metazoan parasite species Tres Palos Lagoon (99°47′W; 16°48′N) is one of the most (37 helminth and 2 crustaceans) in 13 fish species (n= important aquatic resources in the state of Guerrero, 1,498). Specimen collection in this coastal lagoon was done Mexico because of its size (55 km2) and fishery production between April 2000 and November 2003. Digenean species (approximately 900 tons/year; Sagarpa 2000). Located on (18, 8 adult and 10 metacercariae) dominated the parasite the coast, it is predominantly oligohaline (1.5 to 5 ppm) fauna. The most widespread species of parasite were: during most of the year but experiences marine influence Contracaecum sp. (Nematoda), Pseudoacanthostomum during the rainy season when seasonal breaches open panamense, Austrodiplostomum compactum, Ascocotye between the lagoon and the sea. Marine species enter the (Phagicola) longa (Digenea), Neoechinorhynchus golvani lagoon during this season and have a strong influence on its (Acanthocephala), Ergasilus sp. (Copepoda), and Argulus ichthyofauna (Violante-González 2006). Its high productiv- sp. (Branchiura). Parasite fauna species composition ity and the wide variety of fish species from different origin exhibited a clear freshwater influence as 56.4% (22 of 39) (i.e., freshwater, brackish water, and marine water) make of the identified species have a freshwater distribution in the lagoon an ideal habitat to support a rich local parasite Mexico. For 32 of the parasite species, this report fauna. However, published research on the parasite fauna in constitutes the first geographical host record for Tres Palos the fish species of Tres Palos Lagoon is still limited, Lagoon, Guerrero, Mexico. consisting of studies of two nematode species (García- Prieto et al. 2003; Gopar-Merino et al. 2005), the parasite community of one fish species (Garrido-Olvera et al. 2004), and more recently some monogeneans species of one J.
