PARASITOFAUNA OF TILAPIA CAUSE MORTALITIES IN FINGERLINGS IN TWO FISHFARMS, LIMA, PERU

Descripción del Articulo

The parasitofauna in tilapia Oreochromis spp., causing mortality in fingerlings in two cultivation centers, Lima, Peru, was evaluated. We analyzed 50 specimens of 4.0 to 7.0 cm in total length of tilapia grown in greenhouse-like systems and ponds. The gills of each sample were tested and the prepara...

We analyzed 50 specimens of 4.0 to 7.0 cm in total length of tilapia grown in greenhouse-like systems and ponds. The gills of each sample were tested and the preparations were observed microscopically. The presence of the monogenean Gyrodactylus sp. (70% of prevalence) and two ciliate protozoa, Trichodina sp. (70%) and Ambiphrya (syn. Scyphidia) sp. (83.3%) was recorded. Histological changes in infected gills were observed and some cases, the presence of many aneurysms. 20 mL was applied in 100 L of diluted formaldehyde for one h per day for one week to eliminate or minimize the parasitic mortality.El objetivo del presente estudio fue evaluar la parasitofauna en tilapia Oreochromis spp., causante de mortalidad en alevinos en dos Centros de Cultivos, Lima, Perú. Se analizaron 50 ejemplares de 4,0 a 7,0 cm de longitud total de tilapia cultivadas en sistemas tipo invernadero y en pozas. Las branquias de cada ejemplar fueron analizadas y las preparaciones fueron observadas con ayuda del microscopio. Se registra la presencia del monogeneo Gyrodactylus sp. (70%) y de dos protozoarios ciliados, Trichodina sp. (70%) y Ambiphrya (sin. Scyphidia) sp. (83,3%). Se observaron alteraciones histológicas producidas por estos parásitos en los filamentos branquiales y en algunos casos presencia de numerosas aneurismas. Se aplicó 20 mLen 100 Ldel formaldehido diluido durante una h por día y durante una sem para eliminar o minimizar la mortalidad parasitaria.Asociación Peruana de Helmintología e Invertebrados Afines (APHIA) | Universidad Nacional Federico Villarreal2012-12-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.unfv.edu.pe/NH/article/view/1011Neotropical Helminthology; Vol. 6 Núm. 2 (2012): Neotropical Helminthology; 219-2291995-10432218-6425reponame:Revistas - Universidad Nacional Federico Villarrealinstname:Universidad Nacional Federico Villarrealinstacron:UNFVspahttps://revistas.unfv.edu.pe/NH/article/view/1011/895https://revistas.unfv.edu.pe/NH/article/view/1011/2717Derechos de autor 2012 Neotropical Helminthologyhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessoai:ojs2.revistas.unfv.edu.pe:article/10112022-01-11T16:26:48Z
