“…(Cyprinidae) from India revealed that abundance of monogeneans showed an increasing or decreasing trend with the rise and fall in temperature in general, although some monogenean species were more abundant during the monsoon and winter seasons (Shrivastava et al, 2012). Similarly, a previous study conducted within our study area revealed that the abundance of these loricariid species was higher from June to September and was positively correlated with the gonadosomatic index of these fish (Wakida-Kusunoki & Amador-del Ángel, 2011). Therefore, it could be possible that the season of higher abundance of parasites is also related to the reproductive stage of the host, since it is well known that some fish species are more susceptible to parasite infection in periods of higher reproductive investment (Šimková et al, 2005).…”

Parasites of two coexisting invasive sailfin catfishes (Siluriformes: Loricariidae) in a tropical region of Mexico

et al. 2016

Currently many species of Amazon sailfin catfishes (Loricariidae) have been introduced to wild environments outside their native range. There is, however, little knowledge about their role as vectors of parasites that can infect native fish or even humans through its consumption. The aim of the present study was to determine the parasitic fauna of the invasive sailfin catfish species Pterygoplichthys pardalis (leopard pleco) and P. disjunctivus (vermiculated pleco) from freshwater systems in the southeast of Mexico. Four ectoparasite species were found in P. pardalis (1 protozoan: Ichthyophthirius multifiliis; 2 monogeneans: Urocleidoides vaginoclastrum and Heteropriapulus heterotylus; 1 digenean: Clinostomum sp.), and only one in Heteropriapulus disjunctivus (H. heterotylus). No endoparasites were found. Ichthyophthirius multifiliis, U. vaginoclaustrum and Clinostomum sp., were considered as rare species (prevalence <5%) since they were found in a single individual of P. pardalis. H. heterotylus was the only species shared among both host species and it occurs throughout the year. This monogenean species represents 96% of total parasites recorded in P. pardalis and 100% in P. disjunctivus. Monthly values of prevalence, intensity and abundance of H. heterotylus in both host species showed important intra-annual variations, but not differ significantly between both hosts. Actualmente muchas especies de peces conocidos como plecos o peces diablo (Loricariidae) han sido introducidas en ambientes silvestres fuera de su área de distribución natural. Sin embargo, hay poco conocimiento acerca de su papel como vectores de parásitos que puedan infectar a los peces nativos o incluso los seres humanos a través de su consumo. El objetivo del presente estudio fue determinar la fauna parasitaria de las especies de plecos Pterygoplichthys pardalis (pleco leopardo) y P. disjunctivus (pleco vermiculado) en sistemas de agua dulce del sureste de México. Fueron encontradas cuatro especies de ectoparásitos en P. pardalis (1 protozoario: Ichthyophthirius multifiliis; 2 monogeneos: Urocleidoides vaginoclastrum y Heteropriapulus heterotylus; 1 digeneo: Clinostomum sp.) y una en P. disjunctivus (H. heterotylus). No se encontraron endoparásitos. Ichthyophthirius multifiliis, U. vaginoclaustrum y Clinostomum sp. fueron consideradas como especies raras (prevalencia <5%), ya que estuvieron en un solo individuo de P. pardalis. Heteropriapulus heterotylus fue la única especie compartida entre ambas especies de peces y que estuvo presente durante todo el año, y representó el 96% del total de parásitos registrados en P. pardalis y el 100% en P. disjunctivus. La prevalencia, intensidad media y abundancia media de H. heterotylus mostraron importantes variaciones intra-anuales en ambas especies de peces, pero no difirió significativamente entre ambos hospederos.

“…This herbivorous/detritivorous species and its congeners are typical components of freshwater communities throughout much of South America (Armbruster & Page, 2006). Pterygoplichthys pardalis was introduced in Mexico through the commercial aquarium trade and is quickly spreading in southeastern Mexico (Wakida-Kusunoki et al, 2007). Since 2002, P. pardalis is very abundant in artisanal fisheries catches within CWBR (Mendoza-Carranza et al, 2008).…”

Aquatic food webs in mangrove and seagrass habitats of Centla Wetland, a Biosphere Reserve in Southeastern Mexico

et al. 2010

Mangrove and seagrass habitats are important components of tropical coastal zones worldwide, and are conspicuous habitats of Centla Wetland Biosphere Reserve (CWBR) in Tabasco, Mexico. In this study, we examine food webs in mangrove-and seagrass-dominated habitats of CWBR using stable isotope ratios of carbon and nitrogen. Our objective was to identify the importance of carbon derived from mangroves and seagrasses to secondary production of aquatic consumers in this poorly studied conservation area. Carbon and nitrogen isotope ratios of basal sources and aquatic consumers indicated that the species-rich food webs of both habitats are dependent on riparian production sources. The abundant Red mangrove Rhizophora mangle appears to be a primary source of carbon for the mangrove creek food web. Even though dense seagrass beds were ubiquitous, most consumers in the lagoon food web appeared to rely on carbon derived from riparian vegetation (e.g. Phragmites australis). The introduced Amazon sailfin catfish Pterygoplichthys pardalis had isotope signatures overlapping with native species (including high-value fisheries species), suggesting potential competition for resources. Future research should examine the role played by terrestrial insects in linking riparian and aquatic food webs, and impacts of the expanding P. pardalis population on ecosystem function and fisheries in CWBR. Our findings can be used as a baseline to reinforce the conservation and management of this important reserve in the face of diverse external and internal human impacts.Manguezais e pradarias de gramíneas são importantes componentes das zonas costeiras tropicais em todo o mundo, sendo habitats comuns nos "Pântanos de Centla", uma Reserva da Biosfera localizada em Tabasco, México. Nesse trabalho, são investigadas as teias alimentares de habitats dominados por manguezais e pradarias de gramíneas, através de isótopos estáveis de carbono e nitrogênio, tendo como objetivo identificar a importância do carbono derivado desses produtores para a produção aquática secundária nessa unidade de conservação tão pouco estudada. As razões isotópicas de carbono e nitrogênio das fontes basais e dos consumidores aquáticos indicam que as teias alimentares, ricas em espécies, de ambos os habitats, são dependentes da produção ripária. O abundante mangue-vermelho Rhizophora mangle parece ser a fonte primária de carbono no habitat dominado por manguezais. Em contraste, muito embora as pradarias de gramíneas sejam conspícuas no ambiente lagunar estudado, muitos dos consumidores da teia alimentar nessa região parecem depender do carbono oriundo da vegetação ripária (e.g. Phragmites australis). A espécie de bagre exótica Pterygoplichthys pardalis possui assinaturas isotópicas que se sobrepõem a das espécies nativas (incluindo algumas de elevado valor comercial na pesca), sugerindo competição potencial por recursos. Novas investigações deveriam avaliar o papel dos insetos terrestres como elo de conexão entre as teias alimentares da mata ripária e do ambiente aquático, b...

Palabras clave: cuenca Grijalva-Usumacinta, pez invasor, Monte Carlo, IEUBK RESUMEN El objetivo de este estudio fue cuantificar la concentración de metales pesados (Cd, Cr, Mn y Pb) en tejido muscular del pez invasor Pterygoplichthys spp. y estimar el riesgo por exposición oral a estos elementos en infantes usando modelación probabilística de escenarios por el método Monte Carlo en las subcuencas Grijalva y Usumacinta en los estados de Chiapas y Tabasco, México. Se obtuvieron las siguientes concentraciones promedio de metales en tejido muscular en µg/kg: Mn = 734.70, Cr = 315. 16, Pb = 204.62 y Cd = 38.04. Las dosis de exposición estimadas mostraron cocientes de riesgo bajos para ambas subcuencas. Se utilizó el modelo biocinético de exposición integral al plomo (IEUBK, por sus siglas en inglés) para estimar la concentración sanguínea de Pb en infantes de 36 a 60 meses de edad, se calculó el porcentaje de población con niveles > 5 µg Pb/dL en sangre el cual fue de: 2.792 y 7.254 para las subcuencas Grijalva y Usumacinta respectivamente. Ambos resultados muestran que existe un riesgo de exposición a plomo en infantes. Sin embargo, es necesario tener un estudio más detallado en el que se consideren factores como la edad y la talla de los peces capturados, así como evaluar la concentración en subproductos como la harina de pescado, la influencia en la concentración de los procesos de cocinado y la asociación con la exposición a xenobióticos.
