“…For example, Bilong and Tombi (2005) showed that two Monogeneans namely Dactylogyrus in solitus and D. bopeleti gills parasites from Barbus martorelli reached their highest prevalence and their maximum intensity during the rainy seasons. Blahoua et al (2009) also observed that C. acerbus, C. halli and Scutogyrus minus appeared to be more prevalent and more abundant in long rainy season. Our results can be explained by water temperature which is assumed to be an important factor in controlling the occurrence of Monogeneans Simkova et al, 2001).…”

“…Blahoua et al (2009) mentioned the presence in Sarotherodon melanotheron, the genus Scutogyrus and several species of Cichlidogyrus. Ibrahim (2012) showed that eight Monogenean species colonized the gills of Tilapia zillii.…”

“…Mean annual water surface temperature in the reservoir is 28°C (Ouattara et al, 2007). Water surface temperature varied from 25.9 to 26.2°C during the small rainy season and from 29.8 to 32.7°C in the long rainy season (Blahoua et al, 2009). The average dissolved oxygen and water transparency ranged between 2.8 to 15.4 mgl -1 and 550 to 1371 mm respectively (Nobah et al, 2008).…”

“…Studies concerning ecobiological aspects of these parasites are scarce (Nwani et al, 2008;Keremah andInko-Tariah, 2013, Tombi et al, 2014). To the best of our knowledge, there has only been two ichthyoparasitological studies (Blahoua et al, 2009(Blahoua et al, , 2015 on infection dynamics of gill Monogenean parasites of Ivoirian fish.…”

“…Quantitative data on population dynamics of these parasites remain scarce (Bilong Bilong and Tombi, 2005;Nwani et al, 2008). In Côte d'Ivoire, there is almost no information about the dynamics of Monogeneans parasites, the only existing data are from Blahoua et al (2009). In this respect, the composition of Tilapia zillii parasites and their prevalence and mean intensity in Ayame I Lake are of great scientific and applied interest.…”

The study of the gills of 359 Tilapia zillii, which were caught between August 2004 and July 2005, have been investigated in the Ayame man-made lake (Côte d'Ivoire), so as to collect first data on the population dynamics of the Monogeneans parasites in a wild population. Standard methods of parasitological examination were used for identification of Monogenean species. Four Cichlidogyrus species were identified on the gills of host fish: C. digitatus, C. aegypticus, C. vexus and C. yanni. Rates of parasites species were calculated. Prevalence and mean intensity of the Monogenean showed clear fluctuations throughout the year. The parasites were found to settle more on the larger host fish. However, no sex effect was observed on the infestation of T. zillii by the Monogeneans. Throughout the period of study, all parasite species were present, because the recruitment of these organisms, although relatively low, is continuous; this logically results in their accumulation in this fish species.

A new axinid monogenean species, Axinoides euzeti n. sp. from the gills of the Mediterranean needlefish Tylosurus acus imperialis (Rafinesque) off the Tunisian coast is described. The new species is most similar in general morphology to A. meservei Price, 1946 from Tylosurus crocodilus fodiator Jordan & Gilbert off the Atlantic Ocean and to A. kola Unnithan, 1957 from Ablennes hians (Valenciennes) off the Indian Ocean. It can be differentiated from A. meservei by the shape of anterior male genital complex armed with several rows of curved spines on the cirrus rather than 3 to 4 rows of slender spines, in having a fewer testes (87-94 vs more than 100 in the drawing of A. meservei) and a body size twice longer than wide. It differs also from A. kola which have a single row of small spines in the cirrus, in having fewer and wider clamps and fewer and smaller testes. A. euzeti represents the first record of a representative of this genus in the Mediterranean Sea. In addition, taxonomic keys and an updated list of hosts and geographic localities for Axinoides species is presented.
