| dynamics of population of five parasitic monogeneans of oreochromis niloticus linné, 1757 in the dam of loumbila and possible interest in intensive pisciculture. | the study of the gill fishes of 176 oreochromis niloticus (l.) was undertaken in the dam of loumbila (burkina faso), in order to obtain the first information on the dynamics of population of the monogeneans parasites in a population of wild hosts. these data are essential in the search for means to avoid the enormous losses that often occur in intensive pisciculture. this analysis revealed the presence of five species of monogeneans (cichlidogyrus tilapiae, cichlidogyrus halli, cichlidogyrus thu ... | 2008 | 18817262 |
| diversity of metazoan parasites of the mozambique tilapia, oreochromis mossambicus (peters, 1852), as indicators of pollution in the limpopo and olifants river systems. | aquatic systems are affected by a variety of anthropogenic activities that decrease water quality through the introduction of organic and inorganic pollutants. to investigate the relationship between fish parasite communities and water quality, metazoan parasites were examined in 140 specimens of the mozambique tilapia (oreochromis mossambicus) sampled in three lakes in the limpopo province, namely the luphephe-nwanedi dams (regarded as unpolluted), the flag boshielo dam (regarded as moderately ... | 2012 | 23327305 |
| gill monogeneans of oreochromis niloticus (linnaeus, 1758) and oreochromis leucostictus (trewavas, 1933) in lake naivasha, kenya. | an investigation of gill monogeneans from the nile tilapia oreochromis niloticus and the blue spotted tilapia oreochromis leucostictus (50 individuals per species) was done between the months of november 2014 to february 2015 in lake naivasha, kenya. standard parasitological procedures were used to examine fish gills for the presence of monogeneans. the observed monogeneans were collected, preliminarily identified using identification keys, quantified and fixed in 4 % formalin for morphological ... | 2016 | 26691859 |
| parasites of native cichlidae populations and invasive oreochromis niloticus (linnaeus, 1758) in tributary of amazonas river (brazil). | this study provides the first investigation on acquisition of parasites in invasive o. niloticus by parasite species of native cichlidae from the igarapé fortaleza basin, northern brazil. there were examined 576 specimens of 16 species of native cichlids and invasive o. niloticus collected in the main channel and the floodplain area of this tributary of amazon river. the invasive o. niloticus was poorly parasitized having only ichthyophthirius multifiliis, trichodina centrostrigeata, paratrichod ... | 2014 | 24728360 |
| infection dynamics of cichlidogyrus tilapiae and c. sclerosus (monogenea, ancyrocephalinae) in nile tilapia (oreochromis niloticus l.) from uganda. | the infection dynamics of the gill monogeneans cichlidogyrus tilapiae and c. sclerosus on oreochromis niloticus with respect to habitat type (reservoir, stream, ponds and cages), host sex, size and seasons was determined between january and november 2008. during the study period, 45.2% of the 650 fish examined were infected with cichlidogyrus spp. the infected hosts harboured an average of 8.6 ± 3.4 parasites/fish. across habitat types, the proportion of infected fish was not statistically diffe ... | 2012 | 21791155 |
| phylogenetic relationships among monogenean gill parasites (dactylogyridea, ancyrocephalidae) infesting tilapiine hosts (cichlidae): systematic and evolutionary implications. | we studied the systematics of 14 species of monogenean (ancyrocephalidae) gill parasites from west african tilapiine hosts (cichlidae) using both morphological and genetic data. with these tools, we were able to: (i) confirm the validity of the previously described morphological parasite species and of the genus scutogyrus; (ii) propose that some stenoxenous species (i.e., parasite species with more than one host) may be composed of sister species (e.g., cichlidogyrus tilapiae); (iii) state that ... | 2006 | 16214376 |
