“…The absence of acanthocephalan in this research could probably be due to the fact that it was carried out during the rainy season. The earlier work of Goselle et al (2008) and few others showed that helminths have preference for region of attachment in the alimentary canal of fish. In this study, the distribution of gastrointestinal helminth parasites in the fishes showed a clear preference for the intestine and stomach as sites of attachment which could be attributed to the availability of food in these regions.…”

This study was conducted to determine the prevalence of gastrointestinal helminth parasites in Clarias gariepinus with the view of quantifying its helminthic burden in Abuja. The study was carried out in three area Councils of Abuja, Nigeria, between the months of April and August 2015. A total of 83 live fishes (Clarias gariepinus) which includes 28 males and 55 females were randomly purchased from local fishermen and were subjected to examination for gastrointestinal helminth parasites. The lengths and weights of the fishes were measured prior to dissection and the parasites recovered were identified. Results indicated that 56 of the examined fishes were infected with various species of helminth parasites, giving a prevalence of 67.5%. Parasites were identified as Procamallanus laevionchus (32.5%), Rhabdochona congolensis (18.1%), Polyonchobothrium clariae (10.8%), Allocraedium species. (3.6%) and Heterophyid flukes (2.4%). The highest prevalence was recorded for nematodes (50.6%) followed by cestodes (10.8%) and trematodes (6.0%). Worthy of note, was the recovery of Heterophid flukes in this study which have not been previously reported in Nigeria and pose a great zoonotic threat. It was observed that fishes of standard length range of 20-30cm (82.4%) were more infected than those of 30-40cm (65.0%) and 40-50cm (61.5%). The highest prevalence of infection (78.6%) was recorded in fishes with body weight of 500-600g while the lowest (58.8%) was recorded in fishes with body weight of 600-700g. The males had higher percentage prevalence (67.9%) than the females (67.3%). The result of the study indicated that the association (P˂0.05) between the prevalence of infection, sex, length and weight of the host was not statistically significant (χ 2 = 0.00289, 2.24 and 1.55; degree of freedom= 1, 2 and 5 respectively). The helminths recovered were found to parasitize the stomach and intestinal lumen, the latter being more affected.

A cross-sectional study was conducted from November 2015 to June 2016 to determine the occurrence of internal and external parasites in wild fish population of Lake Hashenge and identify the causes of the trends in reduction of fish population. A total of 125 randomly selected fish samples comprising 122 (97.6%) Nile tilapia (Oreochromis niloticus) and 3(2.4%) T. zilli were examined for internal helminthes and external parasites. Overall, 37.6% (47/125) of fish were infested by internal parasites (adults or eggs/larva) while none of them were infested with external parasites. The internal parasites recovered were Clinostomum, Acanthocephalues and Capillaria accounting for 15.2%, 11.2%, and 7.2% of the total infection respectively, while 4% had mixed infection. Moreover, the distribution of parasitic genera were found to be significantly different (p<0.05) with respect to sex, weight, and lengths of the sampled fish, in that females (n=48, 24.8%), fish with body weight 500-1000g (n=89, 30.4%), and length 20-40cm (n=68, 22.4%) were found to be more infected. Most of the respondents (92%) indicated a great reduction in the water and the fish population of the lack from its previous state. All of the respondents have stated that residents of the area wash their clothes in the Lake using synthetic and/or natural detergents and 86% of the respondents believed that Lake Hashenge receives flooding water from nearby uphills and the people use the water from the Lake for small scale irrigation purposes. These findings demand a future focus and stretch of intervention programs for alleviation of the problems facing the Lake before its exhaustion. 76Abreha Tesfaye et al., Ethiop. Vet.

“…The feeding habit of this class of fish exposes them to sources of infection by fish parasites (Biu and Nkechi, 2013). Previous researches have reported that 50 to 90% of Tilapia species harbor at least one species of gastrointestinal parasites (Goselle et al, 2008). Parasitism is much more common and diversified in the wild compared to the farms, ponds and hatcheries.…”

“…Infections occur not only due to overcrowding but also due to environmental stress. A research finding has shown that parasitic infections of Tilapia tend to decrease the growth rate (Goselle et al, 2008).…”

“…Some Tilapia parasites are important diseases causing agents to man. Among the trematodes, Apophallus and other Heterophyids probably develop in the intestine of man, and their ova is trapped in the villi, move into the circulatory system and is filtered out in various organs, including vital organs in the human body (Goselle et al, 2008). Therefore, accurate identification of parasites is important so that a build-up of parasite numbers can be prevented (Goselle et al, 2008).…”

In order to determine the prevalence of gastrointestinal helminths infestation in tilapia species sold in major markets in Gombe, three hundred (300) tilapia fish samples of both sexes and of different age groups were randomly examined. The sample population included 183 adults and 117 juveniles fishes, 157 females and 143 male fishes. Out of the total fishes sampled from three local fish markets, 128 (42.70%) were found to be infested by gastrointestinal helminthes. The prevalence of gastrointestinal helminths in tilapia fishes sampled from Gombe main market (17.0%), Kwadom market (15.0%) and Gombe old market (10.70%) respectively. Three genera of gastrointestinal parasites were encountered at prevalence rates of nematodes (17.70%), trematodes (13.70%) and cestodes (11.30%). The prevalent rates of these gastrointestinal helminths in accordance to sexes of fish shows higher prevalence in female fishes (24.0%) compared to the male fishes (18.70%). There was no statistical significant difference (P= 0.52) in the prevalent rates among the two sexes of fish. However, considering the prevalent rates of gastrointestinal helminths in accordance to ages of fishes, higher frequency was found in adult tilapia fishes (31.00%) than in the juvenile fishes (11.70%). There was statistical significant difference (P= 0.03) prevalent rates among the two ages of fish. Out of the 128 infected fishes examined, nematodes, cestodes and trematodes were all found in the intestines of 71 (23.70%) infected fishes and also in the stomach of 44 (14.70%) infected fishes but only cestodes was found in the gut of 13 (4.30%) infected fishes, while no helminths was recovered in the gills of all infected fishes. The prevalence of gastrointestinal helminths in tilapia species may be one of the significant constraints to the maximum productivity of the fish in the study area. It is therefore recommended that tilapia culturists should be enlighten on the need to routinely treat their fishes using appropriate antehelminthics for maximum production. Moreover, fishes meant for human consumption should be well cooked to prevent human health hazard of acquiring fish-borne helminthes infections.
