Impact of low water temperature on the development of Anguillicola crassus in the final host Anguilla anguilla.
The effect of low water temperatures on the development and viability of larval and adult Anguillicola crassus (Nematoda) in the final host Anguilla anguilla was studied. European eels were experimentally infected with A. crassus and then maintained for 4 mo at 4, 9, 10, and 19 degrees C. Larval development showed a temperature-dependent pattern and was significantly retarded at low temperature...
متن کاملMercury Content in Anguillicola crassus (Nematoda) and its Host Anguilla anguilla
Palíková M., V. Baru‰: Mercury Content in Anguillicola crassus (Nematoda) and its Host Anguilla anguilla. Acta Vet. Brno 2003, 72: 289-294. Mercury content in parasite-host system (Anguillicola crassus and Anguilla anguilla) was studied in the Koryãany Reservoir (Czech Republic). The swimbladder nematode contained the lowest mercury levels (0.050 0.183mg kg-1 wet weight), (p<0.05), compared to ...
متن کاملDistribution and prevalence of Anguillicola crassus (Nematoda) in eels Anguilla anguilla of the rivers Rhine and Naab, Germany.
Over a period of 2 yr eels were collected at several sites along the river Rhine as well as from adjacent waters and examined for Anguillicola crassus in the swimbladder. Additionally eels were collected once from a site on the river Naab (Danube system). All eels were searched for both juvenile and adult stages of A. crassus, revealing prevalences of 80% in eels from the river Rhine and 39% in...
متن کاملBiased sex ratio in the European eel (Anguilla anguilla) swim-bladder parasite Anguillicola crassus, experimentally induced by 11-ketotestosterone.
Parasites are intimately connected to the host in which they live, and some may be affected by the polluted environment of their host. The present study describes the effect of a steroid hormone (11-ketotestosterone) on the sex ratio of the invasive hematophagous nematode Anguillicola crassus Kuwahara, Niimi & Itagaki, 1974, when experimentally injected to European eels, Anguilla anguilla. Our ...
متن کاملThe effect of foraging and ontogeny on the prevalence and intensity of the invasive parasite Anguillicola crassus in the European eel Anguilla anguilla.
Infection patterns of the invasive Anguillicola crassus nematode were investigated in a population of the European eel Anguilla anguilla where parasite invasion is very recent, Loch Lomond, Scotland. Intensity levels of the parasite were associated with differences in fish ontogeny and trophic ecology. Although eels foraged on both fish and invertebrates, individuals which were smaller and fed ...
