Abstract
The results of a study of the cultivated yesso scallop Mizuhopecten yessoensis (Jay, 1857) in Primorsky Krai in 2014–2021 are presented. The death of molluscs in mariculture farms was noted, the symptoms of the “dermo” disease were studied: high mortality of scallops that have reached 2 years of age, observed during autumn displacement into new cages in September, the presence of protozoa of the genus Perkinsus Levine, 1978 in the tissues of organs, foci of damage of the adductor muscle, nonclosure of the shell valves, black discoloration, necrotizing of soft tissues. The minimum level of the parasitic load was established as 10–15 parasitic hypnospores per mollusc. However, considering the danger of a disease that causes mass death of molluscs for several years, the rapid spread of the pathogen, and significant economic losses, it is recommended to create a specialized laboratory in the region for diagnosing and constantly monitoring the state of mariculture farms.
期刊介绍:
The Russian Journal of Marine Biology was founded in 1975 by Alexey V. Zhirmunsky, member of the Russian Academy of Sciences. The Russian Journal of Marine Biology covers a wide range of research and some applied aspects of marine biology as a synthetic science related to various fields of study on marine biota and environment. It presents fundamental research on biological processes at molecular, cellular, organismal, and populational levels in marine organisms. Consideration is given to marine objects as models in life sciences. The journal also publishes papers dedicated to events in Russian and international marine biological science and the history of biology.
