First record of Lamproglena pulchella Nordmann 1832 in the Pielach and Melk rivers, Austria

Abstract

Summary Between April and November 2003, parasitological examinations of the nase Chondrostoma nasus L. and the chub Leuciscus cephalus L. from the neighbouring Melk and Pielach rivers in Lower Austria were conducted. Amongst various gill parasites, Lamproglena pulchella Nordmann 1832 was detected on both fish species, which was the first record of this parasitic crustacean in Austria. Physico‐chemical examinations of water samples of the two rivers were carried out during the same period. The results indicate that general water parameters in the Melk were subjected to more vigorous changes than in the Pielach. Critical temperature levels and ammonia concentration as well as drastic changes in the ionic composition occurred more frequently in the Melk River. The observed distribution of L. pulchella indicates its sensitivity to such stress factors: there was no evidence of the parasite in the Melk River until late November and it only then occurred on the gills of L. cephalus with a prevalence of 20% and a mean intensity of 2. In the Pielach River, infestation on chub had already occurred in June with a prevalence of 40% and a mean intensity of 3, rising to 60% and 7 in November; 45% of the nase was also infested in November at a mean intensity of 3.

“…Dactylogyrus vastator, brought to Europe with the grass carp Ctenopharyngodon idella, causes losses in carp cultures (Schäperclaus, 1990). On the other hand possible consequences of the newly invaded crustacean gill parasite Lamproglena pulchella are unknown yet (Jirsa et al, 2006). Therefore also the influence of the newly introduced B. polymorphus is not known yet.…”

“…It was also tried to determine the effect of water quality on the L. pulchella frequency of presence in Leuciscus cephalus (Galli et al 2001b). L. pulchella was detected in the C. nasus (Jirsa et al 2011;Jirsa et al 2006) and L. cephalus (Jirsa et al 2006) fish species caught in rivers in Austria. The parasite mentioned above was also determined in the gills of L. cephalus in Serbia (Cakic et al 1998) and Scardinius erythrophthalmus in Turkey (Kus and Soylu 2013;Soylu 2012).…”
