Length and weight of Ligula intestinalis plerocercoids (Cestoda) parasitizing adult cyprinid fishes (Cyprinidae): a comparative analysis.

Popis výsledku v původním jazyce

Assessed comparatively were the parameters of length and weight of Ligula intestinalis plerocercoids parasitizing as single and multiple infections in three adult (3+ and more) fish species (roach, silver bream, bream). The hypothesis that the body sizeof an endoparasitic species can be related to the host body size and longevity, and for tapeworm larval stage (plerocercoid) and intermediate host (fish) was confirmed. At single parasite infection intensity, the niche spatial volume (fish body cavity) is not occupied fully, and therefore conditions for growth and parasite reinfection are maintained. At multiple infections, intraspecies competition for the niche space on different levels are observed. These conclusions are documented by significant differences in length and weight of plerocercoids and parasite index values. The presence and intraspecies competition level were tested effectively from plerocercoid condition, expressed by the parasite length-weight relationship.
