“…In this study, lernaeosis affected fish showed swollen hyperemic nodules and open wounds at the site of attachment of macroscopic lernaea parasitic females on the body and fins (Figure 2). Similar clinical abnormalities of affected cyprinids were reported by Abd El-Rahman (2000); Abd El-Galil ( 2002); Mancini et al (2006);Abd El-Galil et al (2012);Noor El-Deen et al (2013) and Korni (2014). Also, in this investigation the safety and effectiveness of trichlorfon in lernaeosis control in C. idella fingerlings was compared with carvacrol and cymene mixture and thyme which are the major components of thyme extract (Rattanachaikunsopon and Phumkhachorn, 2010) as safe natural by-products.…”

This study was carried out to evaluate the safety and effectiveness of trichlorfon in prevention of lernaeosis among hatchery-reared cyprinids. Also, it compared with plant extracts (carvacrol and cymene mixture and thyme) in lernaeosis control. At the Abo-Saleh fish hatchery in BeniSuef, Egypt, the trichlorfon bioconcentrations of cyprinids fries and fingerlings, as well as soil, water and plant samples were examined for 2 years. Trichlorfon was detected in fingerlings, water and plant samples, except soil sampled 1 hr after trichlorfon was applied to the fish pond. The highest concentration of trichlorfon was in fish, followed by water and plant samples. No trichlorfon was detected in fingerlings, water, plant and soil sampled after 5 days and 5 months. Fingerlings and brooders of cyprinids were examined in situ for clinical abnormalities and prevalence of lernaeosis. In addition, the intensity of the lernaea infestation was determined. Macroscopic Lernaea cyprinacea females were seen attached to the skin and fins associated with swollen hyperemic nodules and open wounds. Lernaeosis appeared sporadically during examination seasons with a high intensity. Under experimental condition, trichlorfon succeeded in controlling lernaeosis among Ctenophyrngedon idella fingerlings, as it eliminated 100% of Lernaea cyprinacea in comparison with 74.28% and 50.2% in carvacrol and cymene mixture and thyme treated fish respectively.

The pejerrey Odontesthes bonariensis is the most important freshwater fish of Argentina central region. The present study was conducted to describe the seasonal variation of parasitism in O. bonariensis from La Viña reservoir (31 degrees 17'S, 65 degrees 01'W), located in the province of Córdoba, Argentina. Between years 1999 and 2002, 573 fishes were caught, and their parasite infection and relative weight (Wr) were assesed. Three parasites were found, Lernaea cyprinacea (Crustacea), Contracaecum spp. larvae (Nematoda) and Cangatiella macdonaghi (Cestoda). Overall, Contracaecum spp. prevalence and intensity were very low. Lernaea cyprinacea and Cangatiella macdonaghi prevalences increased during summer and spring (P < 0.01), respectively. Lernaea cyprinacea infection showed also seasonal differences in intensity (P < 0.05), as well as C. macdonaghi regarding parasites density (P < 0.01). Cangatiella macdonaghi average parasites density was 32.0 (+/-22.5) cestodes per cm(3)of digestive content. No association between parasitism and fish relative weight was found. Besides the seasonality variations observed, the parasite burden found did not compromise fish body condition.

A few studies were focused on helminth populations of silverside (mancini et al, 2008), however, no previous studies have focused on the parasite communities of this fish species.…”

ABSTRACT. The helminth communities of silverside, Odontesthes bonariensis (Valenciennes, 1835), from two Argentinean lagoons were studied and compared at component community and infracommunity levels. Nine helminth species were found: five digeneans (Austrodiplostomum cf. mordax, Ascocotyle (Phagicola) cf. diminuta, Ascocotyle sp., Thometrema bonariensis and Saccocoelioides sp.); two nematodes (Contracaecum sp. and Hysterothylacium sp.); one acanthocephalan (Wolffhugelia matercula) and one cestode (Cangatiella macdonaghi). Odontesthes bonariensis is a new host record for five parasite species. Richness, diversity and number of helminths in silversides from Salada Grande lagoon were higher than in those from Lacombe lagoon. This could be related with lagoon size, abundance of mollusks and fish-eating birds, and size and diet of silversides captured in each lagoon. In Salada Grande lagoon the helminth community of silversides was dominated by the allogenic and generalist species A. cf. mordax; while the autogenic and intermediate specialist species C. macdonaghi was dominant in Lacombe lagoon. Host sex did not affect richness, diversity or total abundance, whereas host size was positively correlated with these attributes, except diversity in Salada Grande lagoon. KEYWORDS.Helminth community, infracommunity, Platyhelminthes, Nematoda, Acanthocephala. RESUMEN. Estructura de la comunidad de metazoarios parazitos del pejerrey, Odontesthes bonariensis (Pisces, Atherinopsidae) from Argentina. Las comunidades de helmintos del pejerrey, Odontesthes bonariensis (Valenciennes, 1835), procedentes de dos lagunas argentinas fueron estudiadas y comparadas a nivel de comunidad componente e infracomunidad. Se hallaron nueve especies de helmintos, cinco digeneos (Austrodiplostomum cf. mordax, Ascocotyle (Phagicola) cf. diminuta, Ascocotyle sp., Thometrema bonariensis y Saccocoelioides sp.); dos nematodes (Hysterothylacium sp. y Contracaecum sp.); un acantocéfalo (Wolffhugelia matercula) y un cestode (Cangatiella macdonaghi). Odontesthes bonariensis es reportado como un nuevo hospedador para cinco de estas especies. La riqueza específica, la diversidad y la carga parasitaria fueron mas elevadas en la laguna Salada Grande que en la Laguna Lacombe. Esto podría estar relacionado con atributos del cuerpo de agua (tamaño, abundancia de moluscos y aves ictiófagas) y del hospedador (talla y dieta de los pejerreyes capturados en cada laguna). En la laguna Salada Grande, la comunidad de helmintos fue dominada por una especie alogénica y generalista, A. cf. mordax; mientras que en la laguna Lacombe fue dominada por un a especie autogénica y especialista intermedia, C. macdonaghi. El sexo del hospedador no estuvo correlacionado con la riqueza específica, diversidad y carga parasitaria, mientras que la talla del hospedador presentó correlación positiva con estos atributos, excepto la diversidad en la laguna Salda Grande.
