Intestinalparasites of Oreochromisniloticus in Ebonyi River, Southeastern Nigeria: Implication for fish health policy and management
Journal Title: IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) - Year 2018, Vol 11, Issue 10
Abstract
The prevalence of intestinal parasites in Oreochromisniloticuswas investigated at Ebonyi River flood system from October 2015 to November 2015. Using standard parasitological analysis the incidence of intestinal parasites of O. niloticus was studied. Procamallanus (Nematoda) had the highest prevalence (9.32%) while Opisthochuspedicellantus and Monobothroideswoodlandii (cestoda) have the lowest prevalence of (0.62%) and (0.62%) respectively. Other parasites include Enterogyruscichlidarum(Nematoda), (3.1 I %),Acanthostomumspiniceps(Acanthocephalan),(4.97%)Clinostomumarthracanthus(3.73%), Clinostomumtilapiae (2.48%),Clinostomumpillariazederi (Trematoda) (1.86%), Unidentified Cestode larva (3.11%).The fish within the length range of 11.00-12.50 (TLcm) were most infected while those within the range of 9.00-10.50 and 15.00-16. 50 (TLcm) were less prone to infection. Samples with body weight with the range of 41-50.00(g) were most susceptible to infection. The distribution of parasites in relation to the various region of the body of wild Nile tilapia shows that most parasites that infect this species are mostly found in the stomach with (40%) followed by small intestine (35%) gills, (21%) and muscles (7%) but only (2%) of these parasites were found in the gall bladder. The prevalence of intestinal parasites of O. niloticusin Ebonyi River is as a result of anthropogenic activities, discharge of waste waters and products into the river due to poor sewage disposal. Therefore, the presence of helminthparasite might elicit some pathological effects on the wild Nile Tilapia retarding their growth, even causing death.
