“…Factors regulating parasite life cycles are both abiotic (temperature, salinity, oxygen, ammonia, pH, etc.) and biotic (host immunological response, diet and feeding behaviour, and availability of infected intermediate hosts as food (Williams and Jones 1994)).…”

Populations of Lamproglena pulchella von Nordmann 1832 (Copepoda: Eudactylinidae) in cyprinid fish in rivers with different pollution levels

et al. 2001

A total of 512 chub (Leuciscus cephalus L.) individuals sampled from four rivers with different pollution levels were examined for Lamproglena pulchella (von Nordmann 1832) prevalence and mean intensity. As a result of the L. pulchella mode of reproduction, the parasite populations showed a significant degree of aggregation. The results, excluding the effect of fish health conditions on the parasite infection, provide evidence of the influence of water quality on parasite prevalence. Parasite density increase in relation to fish length and age suggests a dependence of infection intensity to the exposure time on the fish.

“…Marine fish constitute about 90% of total world fish production (approximately 80 million tons) but the availability of fish supplies can be affected by parasites and diseases, which could ultimately affect nutrition and hence economics of populations (Rohde, 1993 andHadfield, 2007). The total number of described fish helminthes exceeds far more than 30.000 species (Williams and Jones, 1994). The Neodermata or parasitic Platyhelminthes comprise an enormous diversity of species that occur in all seas, rivers and lakes and on all continental land masses.…”

A total of 85 fish specimens of the great barracuda, Sphyraena barracuda (Edwards, 1771) from the Red Sea, Yemeni coastal waters were examined for infection with the polyopisthocotylean monogeneans during the period from October 2009 till May 2010. The results showed the occurrence of two species of these parasites; Vallisiopsis contorta Subhapradha, 1951 and Pentatres sphyraenae Euzet and Razarihelisoa, 1959. The occurrence of these monogeneans represents their first record from the Yemeni fishes of the Red Sea.

“…The development of cestode eggs and coracidia is affected by a variety of environmental factors, the most important of which is water temperature (Williams & Jones, 1994). Thus, the aim of this study was to determine seasonal variation of infection in Cyclops vicinus Uljanin, 1875 infected with cestode procercoids, and interactions between the infection and some physical characteristics of the water in Lake Hazar.…”

In this study, the seasonal variation of natural levels of infection in Cyclops vicinus Uljanin, 1875 with procercoids of cestodes was examined in Lake Hazar, Turkey from November 2005 to October 2006. The prevalence of infected C. vicinus was found to increase with water temperature (p < 0.01); a peak occurred in September, while relatively low levels were recorded between November and March. No statistically significant relation was determined between infection and pH values (p > 0.05). However, a statistically significant, negative correlation was found between infection and dissolved O 2 level (p < 0.05). Each infected Cyclops carried only one procercoid. RÉSUMÉDans cette étude, la variation saisonnière des niveaux naturels d'infection chez Cyclops vicinus Uljanin, 1875 par les procercoïdes de cestodes a été examinée au lac Hazar, Turquie, de novembre 2005 à octobre 2006. La prévalence de C. vicinus infectés augmentait avec la température de l'eau (p < 0.01); un pic s'est produit en septembre, alors que des taux relativement bas ont été relevés entre novembre et mars. Aucune relation statistiquement significative n'a été déterminée entre l'infection et les valeurs du pH (p > 0.05). Cependant, une corrélation négative statistiquement significative a été constatée entre l'infection et le niveau d'O 2 dissous (p < 0.05). Chaque Cyclops infecté portait un seul procercoïde. 1 )
