Parasites of the sprats of some zones of the Caspian Sea in the water area of Azerbaijan
Seyidli YM and Nasirov ÐÐœ
During the period of research, 6 species of parasites were detected in the sprat. From the selected parasites 1 species refers to ciliates (Trichodina caspioloza),1 species to monogeneans (Mazokraes alosae), two species to trematodes (Pronoprymna ventricosa and Bunocotyle cingulata), 1 species to acanthocephalans (Corynosoma caspicum) and 1 species to the nematodes (Anisakis schupakovi).Of these, Trichodina caspialosae and Mazocraes alosae develop without a change of hosts. Among the parasites of sprats, predominantly, Pronoprymna ventricosa trematode, a specific parasite of herrings. More species of parasites were identified in ordinary sprat than in anchovy sprat. This is due to the habitat of ordinary sprat in the coastal waters, the environment of which favorably affects the development of the intermediate host of some parasites. Anchovy sprat inhabits far from the coastal zones of the sea, where the species diversity is lower than the coastal thickening. All the parasites found in the sprats are typical marine species.
