“…Season-related host feeding patterns, availability of infected intermediate hosts, immunological and hormonal changes, are the most frequently suggested causes for seasonal fluctuation in prevalence and abundance of parasitic infections (Kim et al, 2001). We found a significant negative correlation between rain fall and infection rate for B. tanapelagius, but not for B. humilis.…”

Pseudophyllidean cestodes as Ligula have a complex life cycle with cyclopoid copepods as first intermediate host, zooplanktivorous fish as second, and piscivorous birds as final host. We studied the effects of diet, season and habitat occupation on the prevalence of plerocercoid larvae of the tapeworm Ligula intestinalis in two closely related small barbs and the effects of the parasites on the barbs life histories in Lake Tana (Ethiopia) during 1 year. In all affected barbs L. intestinalis caused retardation in gonad development, maturation at reduced size and lower absolute fecundity. Infection rate, averaged over all habitats was significantly higher in B. tanapelagius (10%) than in B. humilis (6%). Below a threshold of 48 mm the infection rate was zero for both barbs, this coincided with a very low proportion of copepods in their diets, increasing up to 90 and 55%, respectively, for their largest size class (81-90 mm). The relatively high infection rate in B. tanapelagius is explained by its obligatory zooplanktivorous feeding behaviour, ingesting a relatively high proportion of infected cyclopoid copepods. This is in contrast with B. humilis, which is a polyphagous species, feeding both on zooplankton and benthic invertebrates. Significant seasonal effects in infection rates were observed. In both barb species infection rates were lower during the breeding season. Only for B. tanapelagius a significant negative correlation was observed between rain fall and infection rate, probably caused by an increased turbidity that decreases feeding efficiency on zooplankton. Habitat type had also a significant effect on infection rate. Barbus humilis showed a much higher infection rate in shallow clear water (10%) than in shallow turbid water (3%), whereas B. tanapelagius showed much higher infection rates in the shallow sublittoral (13%) than in the deeper pelagic (7%). Most likely, birds predate more efficiently on barbs in shallow clear waters than in shallow turbid and deep waters.

“…Many studies conducted on the behaviour of parasites in culture conditions have shown that water temperature is the major abiotic factor affecting reproduction and population growth (Oliver, 1987). Generally, high water temperature levels promote faster hatching of eggs and parasites propagate rapidly (Gannicott & Tinsley, 1998;Kim et al, 2001;Silan & Maillard, 1989). Cyclic peaks of many parasites species have been mainly registered in sea cages during summer months (Andersen and Buchmann, 1998;Cecchini et al, 1998;Gelnar, 1987).…”

“…They also explained that this might be the result of the higher food consumption of females; thus, females are more likely to become infected by copepods. Kim et al (2001) also reported that the period of peak abundances of Prosomicrocotyla gotoi and Opecoelus sphaericus infections corresponded well to the spawning season (from October to January) of the greenling Hexagrammos atakii. Moharram (1980) studied the parasitic fauna of Merluccius merluccius from Alexandria and found that female fish were more susceptible to infections with cestode, nematode, and copepod parasites than males.…”

IntroductionThicklip grey mullets, Chelon labrosus (family Mugilidae), are commonly found from the coastal regions of the eastern Atlantic, Scandinavia, and Iceland to southern Senegal and the Mediterranean Sea and southwestern Black Sea. They live inshore, in brackish lagoons and fresh water, and they tend to move northward in the summer as the temperature rises. Little is known about the parasitic fauna of C. labrosus. To our knowledge,
