“…The omnivorous behaviour and resulting continuous intake of infected intermediate hosts led to accumulation of TTP species, culminating in high mean intensities (Esch and Fernändez 1993;Marcogliese 2002). In general, the present findings support previous reports on the parasite faunas, which show that O. niloticus is dominated by FTP species (BondadReantaso and Arthur 1990;Opara and Okon 2002;Musa et al 2007) and that C. gariepinus is dominated by TTP species Nkwengulila 2004, 2008).…”

Parasite fauna of farmed Nile tilapia (Oreochromis niloticus) and African catfish (Clarias gariepinus) in Uganda

et al. 2011

An intensive parasite survey was conducted in 2008 to better understand the parasite fauna occurrence, distribution and diversity in the commercial aquaculture fish species in Uganda. A total of 265 fish collected from hatcheries and grow-out systems were examined for parasites using routine parasitological techniques. The survey yielded 17 parasite species: 11 from Oreochromis niloticus and ten from Clarias gariepinus. Four parasites-Amirthalingamia macracantha, Monobothrioides sp., Zoogonoides sp. and a member of the family Amphilinidae-were recorded for the first time in the country. The parasite diversity was similar between hosts; however, O. niloticus was dominated by free-living stage-transmitted parasites in lower numbers, whereas both trophically and free-living stage-transmitted parasites were equally represented in C. gariepinus in relatively high intensities. The patterns in parasite numbers and composition in the two hosts reflect differences in fish habitat use and diet. A shift in parasite composition from monoxenous species-dominated communities in small-sized fish to heteroxenous in large fishes was recorded in both hosts. This was linked to ontogenetic feeding changes and prolonged exposure to parasites. Polyculture systems showed no effect on parasite intensity and composition. The gills were highly parasitized, mainly by protozoans and monogeneans. Generally, the occurrence and diversity of parasites in these fish species highlight the likelihood of disease outbreak in the proposed intensive aquaculture systems. This calls for raising awareness in fish health management among potential farmers, service providers and researchers.

Reviews in Aquaculture

Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia. Capture fisheries account for a further 723,627 tonnes of tilapia, and >47% of this is landed from established invasive populations outside Africa. Tilapias host a rich fauna of parasites, many of which have been translocated with their hosts. This review summarises >2500 host–parasite records from 73+ countries and >820 recorded tilapia translocations (provided in the supplementary materials). This work focuses on the notable pathogens that threaten the health of cultured populations of tilapia, providing a description of their pathology and includes species that also have substantial impacts on wild tilapia populations, where relevant. For each major parasite taxonomic group, we highlight which parasites have been translocated or have been acquired from the new environments into which tilapia have been introduced, together with remarks on standard treatment approaches and research on them and their management and control. Regarding the theme ‘Tilapia health: quo vadis?’, Africa has enormous potential for aquaculture growth, but substantial knowledge gaps about tilapia parasites in many African states remain, which creates associated production and biosecurity risks. For each parasitic group, therefore, the risks of parasite translocation to new regions as tilapia aquaculture industries expand are highlighted.

“…Ce comportement omnivore résultant en une ingestion continue d'hôtes intermédiaires, entraîne l'accumulation des espèces TTP, avec des intensités moyennes élevées (Esch et Fernandez, 1993 ;Marcogliese, 2002). En général, les présents résultats sont en accord avec de précédentes études sur la faune parasitaire de O. niloticus dominée par les espèces à transmission par stage libre (FTP) (Bondad-Reantaso et Arthur, 1990 ;Opara et Okon, 2002 ;Musa et al, 2007) et de C. gariepinus plutôt dominé par les espèces de parasites à transmission trophique.…”

Tél: (00229)97645885). RESUMEUn relevé parasitaire a été réalisé en 2016 afin de mieux comprendre la présence, la répartition et la diversité de la faune parasitaire chez les espèces piscicoles commerciales, Clarias gariepinus et Oreochromis niloticus provenant des whédos du delta supérieur de l'Ouémé au sud du Bénin. L'échantillonnage a été réalisé dans les trois communes du haut delta de l'Ouémé (Bonou, Ouinhi, Zagnanado). Trente whédos artificiels ont été sélectionnés à raison de dix par commune. Un total de 757 poissons (417 C. gariepinus et 340 Oreochromis niloticus) ont été collectés durant les deux périodes de crue et de décrue du fleuve Ouémé et ont été examinés pour des parasites en utilisant des techniques parasitologiques de routine. Onze (11) taxons parasites ont été observés chez les deux espèces hôtes : 6 taxons sont présents chez Oreochromis niloticus et 7 chez Clarias gariepinus. Deux taxons, Clinostomum sp. et Gryporhynchidae, sont observés chez les deux espèces hôtes. La parasitofaune de O. niloticus est dominée par des taxons à transmission par stade libre, tandis que les parasites à transmission par stade libre et les parasites à transmission trophique sont également représentés chez C. gariepinus. Les branchies sont très faiblement parasitées, mais fortement par des monogènes. L'intestin est fortement parasité, principalement par les nématodes et les trématodes. En général, l'occurrence et la diversité des parasites chez ces espèces de poissons mettent en évidence la probabilité d'une résurgence de pathologies dans les systèmes aquacoles étudiés. Ceci appelle à une sensibilisation des agriculteurs, des pisciculteurs, des fournisseurs de services et des chercheurs pour une meilleure gestion de la santé des poissons. © 2019 International Formulae Group.
