| 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 |
| molecular phylogeny of monogeneans parasitizing african freshwater cichlidae inferred from lsu rdna sequences. | the african freshwater fish of cichlidae are parasitized by five genera of monogeneans belonging to dactylogyridea. ectoparasitic scutogyrus, onchobdella, and the highly diversified cichlidogyrus represent three genera located on the gills, while the endoparasitic enterogyrus and urogyrus are located in the stomach and the urinary bladder, respectively. representatives of four dactylogyridean genera (except for urogyrus) were collected from seven cichlid species in west africa. the aim of this s ... | 2010 | 20697913 |
| seasonal variation on the ectoparasitic communities of nile tilapia cultured in three regions in southern brazil. | a total of 240 nile tilapia were examined between april 2007 and march 2008, gathered from three different fish farms, 20 fish in each fish farm, in the four seasons of the year. fish ponds were located in joinville, blumenau and ituporanga, santa catarina state, brazil and each pond had a different culture system. prevalence, mean intensity, mean abundance and mean relative dominance were compared among fish ponds and seasons. during this period, the water quality was kept in normal values. pis ... | 2011 | 21755153 |
| 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 |
| ectoparasites of nile tilapia (oreochromis niloticus) in cage farming in a hydroelectric reservoir in brazil. | for this study, we performed a parasitological analysis of cage-cultured nile tilapia (oreochromis niloticus) from the água vermelha reservoir, southeastern brazil, and verified relationships with limnological data, seasonality, and fish growth phase. from march 2010 to march 2011, sixty-three specimens of o. niloticus in three growth phases (i.e., initial, intermediate, and final) were collected. all fish specimens were infested with at least one ectoparasite species (prevalence = 100%). five s ... | 2014 | 25054495 |
| monogenean community structure of oreochromis niloticus in relation to heavy metal pollution and host reproductive cycle. | the community structure of monogenean parasites of oreochromis niloticus and its relation to the variations of heavy metal concentrations in water and the host reproductive cycle (gonadosomatic index, gsi) was studied. fish were collected from fishermen lake, ismailia. monogenea community consisted of seven species, cichlidogyrus halli typicus (57.8%), c. thurstonae (35.3%), c. ergensi (13.8 %), c. tiberianus (16.4%), c. arthracanthus (13.8%), scutogyrus longicornis (22.4%) and gyrodadtylus cicc ... | 2012 | 22662591 |
| first report of monogenean flatworms from lake tana, ethiopia: gill parasites of the commercially important clarias gariepinus (teleostei: clariidae) and oreochromis niloticus tana (teleostei: cichlidae). | lake tana is the largest lake in ethiopia and the source of the blue nile. the lake harbours unique endemic cyprinid fish species, as well as the commercially important endemic nile tilapia subspecies oreochromis niloticus tana and the north african catfish clarias gariepinus. its endemicity, especially within the labeobarbus radiation, its conservation importance and its economic indispensability attract scientific interest to the lake's ichthyofauna. fish parasites of lake tana, however, are h ... | 2016 | 27457488 |
| effect of dietary supplementation with propolis and aloe barbadensis extracts on hematological parameters and parasitism in nile tilapia. | this study evaluated the influence of diet supplementation with propolis and aloe barbadensis on hematological parameters and parasitism in tilapia. one hundred and eighty fish were distributed among 12 water tanks forming four treatments: fish supplemented with a 1:1 mixture of 0%, 0.5%, 1% and 2% propolis and aloe extracts. after the fish had been fed on the experimental diets for 15 and 21 days, blood samples were taken and parasites collected. the monogeneans cichlidogyrus sclerosus, c. hall ... | 2015 | 25909255 |
