“…Measurements of the total length of the first pair of hamuli in the present investigation coincided with those reported by Charles et al (1997), while they were smaller than those reported by Paperna (1969) and El-Naggar (1987). Measurements of the total length of the second pair of hamuli (present study) were larger than those reported by Paperna (1969), El-Naggar (1987) and Charles et al (1997). Also, the penis length was coinciding with that reported by El-Naggar (1987), but it was smaller than that reported by Charles et al (1997).…”

“…Table (2) shows intraspecific variations between the measurements of P. malapteruri in the present work and those previously described. The total body length in the present study was larger than those reported by Paperna (1969) and Charles et al (1997), while it coincided with that reported by El-Naggar (1987). Moreover, the maximum body width was smaller than those reported by El-Naggar (1987) and Charles et al (1997).…”

“…Protoancylodiscoides malapteruri Charles et al 1997 : In the present study, P. malapteruri was obtained from the gills of M. electricus and interestingly the same species was reported from the same host by Charles et al (1997) from Cameron. There were other two species of Protoancylodiscoides; P. mansourensis obtained from the Nile catfish Chrysichthysauratus from Damietta Branch of the River Nile by El-Naggar (1987) and P. chrysichthes from Ch. nigrodigitatus (Paperna, 1969).…”

Parasitic diseases are responsible for important economic losses in aquaculture (Osman et al., 2010) and however, Fish are a good source of quality protein, various diseases including parasitic infections pose a threat to fish cultivation, which is a valuable source of food and employment in developing countries Yooyen et al. (2006). No doubt, that fishes harbor a wide range of ecto-and endoparasites infecting the alimentary canal, liver, kidney, reproductive organs, muscles as well as gills and skin (El-Naggar & Khidr, 1988 and Yang et al., 2005). Ecto-parasites are the most dangerous group that causes severe mortalities (Shalaby and Ibrahim, 1988). In Egypt,

Gill monogeneans of Nile tilapia (Oreochromis niloticus) and red hybrid tilapia (Oreochromis spp.) from the wild and fish farms in Perak, Malaysia: infection dynamics and spatial distribution

Tilapia is one of the commercially important fish in Malaysia as well as in other parts of the world. An understanding of monogenean infection dynamics in tilapia fish may assist us in searching for some intervention measures in reducing the loss of fish caused by parasitic diseases. The present study aimed (1) to compare infection level of monogeneans between the wild and cultured Oreochromis niloticus, and between the cultured O. niloticus and cultured red hybrid tilapia, and (2) to examine the spatial distribution of monogenean species over the gills of the different host species. From a total of 75 fish specimens, six species of monogeneans from two genera: Cichlidogyrus (C. halli, C. mbirizei, C. sclerosus, C. thurstonae, C. tilapiae) and Scutogyrus (S. longicornis) were identified. Data showed that the infection level of cultured O. niloticus was higher than that of the wild O. niloticus, however, the former was lower than that of the cultured red hybrid tilapia. Higher species richness of monogeneans was observed in the cultured red hybrid tilapia as compared to the others. Results for spatial distribution showed that the monogeneans have no preference on the left or right sides of the gills. However, C. halli, C. mbirizei, and C. tilapiae showed preferences on specific gill arches in the cultured O. niloticus and red hybrid tilapia. In general, the gill arch IV harboured the least number of monogeneans. The susceptibility of monogenean infection between the different types of tilapia is discussed.
