“…It is therefore a plausible explanation that the big fish provides a good ground for the parasites to multiply over time. Vankara et al 2011 found that parasite richness and diversity are poorly correlated with the host size. Blackburn and Lawton (1994) and Blackburn and Gatson (1997) documented relationship between parasite abundance and body size.…”

A parasitological investigation was done on 175 specimens. Infections of A. brama orientalis were analyzed according to the age and sex. The fish also were examined for evaluation changes of haematological parameters in relation to parasitic infection. Four parasites were found, including-Caryophyllaeus laticeps and Ligula intestinalis (Cestoda), Diplostomum spathaceum (Platyhelminthes) and Trichodina sp. (Ciliophora). Among identified parasites maximum prevalence and mean intensity were related to Ligula intestinalis and Caryophyllaeus laticeps respectively. The values of prevalence and mean intensity showed significant differences among ages. Our results revealed prevalence, mean intensity and abundance had not significant difference between males and females. Parasite infection provoked reduction (P \ 0.05) in haematocrit, mean cell volume and lymphocyte. On the other hand, significant increase (P \ 0.05) in white blood cell (WBC), mean cell haemoglobin concentration and neutrophil in blood of infected fish was observed. Significant differences were detected for the WBC, lymphocyte and neutrophil (infected versus uninfected by Trichodina sp., Diplostomum spathaceum and Caryophyllaeus laticeps). In addition to WBC and lymphocytes, significant change was observed for the haemoglobin (Hb) (infected versus uninfected by Ligula intestinalis).

“…Ecological studies on parasites provide information about interrelationships between parasites, and their hosts about biodiversity of parasites and their distribution in a particular water system (Marcogliese, 2004;Vankara et al, 2011). The epidemiological data are particularly important when fi sh parasites are considered as the potential risks for aquaculture candidate species.…”

SummaryThis study provides information on seasonal occurrence of developmental stages of endoparasites infecting three cyprinids in the Nwanedi-Luphephe dams, Limpopo River System. Labeobarbus marequensis (Smith, 1841), Barbus trimaculatus Peters, 1852 and Barbus radiatus Peters, 1853 were investigated seasonally from January 2008 to October 2008. The following larvae of metazoan parasites were collected: Diplostomum sp. from the eyes of L. marequensis and B. trimaculatus; Ornithodiplostomum sp. from the gills of B. trimaculatus; Posthodiplostomum sp. from muscle, skin and fi ns of B. trimaculatus and B. radiatus; third-stage Contracaecum larvae (L3) from the mesentery fats and on the liver lobes of L. marequensis and B. trimaculatus and gryporynchid cestode larvae from the outer intestinal wall of B. radiatus. All the fl ukes encountered were metacercariae. Diplostomum sp. and Contracaecum sp. dominated the parasite communities. Their prevalence exhibited seasonal fl uctuations with maxima in summer. Factors likely to infl uence fi sh infection such as the body size of fi sh and their condition factors were also briefl y considered in this study.

“…In addition, Valtonen et al (1990) and Roubal (1990) found higher levels of parasitism in hosts with intermediate lengths. Furthermore, Vankara et al (2011) Some factors affecting metacercarial infections in T. zilli from Lake Timsah, Ismailia, Egypt 25 prevalence of infection in Mugil armatus is low in small fish, high in medium size and decreasing in larger fish. Apparently, fish acquire the parasite in their youth phase which is then eliminated in the fish in adult phase which might be due to aging of the parasites or immunological resistance of fish (Takemoto and Pavanelli, 2000).…”

The objective of this work is to study some environmental and biological factors affecting metacercarial infections in Tilapia zilli from two sites at Lake Timsah, Ismailia, Egypt. Fish were collected monthly from two sites during a period from March 2009 to February 2010. Fish length and sex were determined. Five different trematode metacercariae were recovered from T. zilli fish, namely, Euclinostomum sp., Pygidiopsis sp, Phagicola sp., and Stictodora sp. and some were undifferentiated. Infection was higher in site 2 (42.4%) than site 1 (32.59%). The highest infection was recorded in winter (79.76%), and the lowest in spring (9.52%). It was the highest (40.51%) in medium-sized fish. Males were more infected (38.93%) as compared to females (30.04%). Prevalence, intensity and abundance of each metacercaria species showed different responses to the considered factors as discussed in this work.
