Материалом для данного исследования служили собственные сборы личинок (метацеркарий) трематод от 283 экз. брюхоногих моллюсков Hydrobia acuta, сделанные в марте 2012 г. в эстуарии р. Черная (г. Севастополь, Черное море, 44°27′49″ с. ш. 33°51′37″ в. д.). Моллюсков исследовали компрессорным методом на наличие гельминтов. Часть особей найденных трематод исследовали живыми, других – фиксировали в 70%-ном этиловом спирте, затем окрашивали ацетокармином по стандартной методике. Морфологические особенности метацеркарий изучали на живых личинках.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение.

The material for this study was trematode larvae (metacercariae) from 283 specimens of gastropods Hydrobia acuta that we collected in March 2012 at the estuary of the River Chernaya (Sevastopol, the Black Sea, 44°27′49″ N 33°51′37″ E). The gastropods were studied for helminths using the compression method. Some of specimens of the found trematodes were studied alive and others were fixed in 70% ethyl alcohol and then stained with acetocarmine according to the standard method. The morphological features of metacercaria were studied on live larvae.</p></sec><sec><title>Results and discussion</title><p>Results and discussion.
