Scientists have developed tools to extract anadara in the Sea of Azov

Scientists of the All-Russian Research Institute of Fisheries and Oceanography (VNIRO) have developed tools for the extraction of a new biological object of fishing in the Sea of Azov. This was reported on Friday, November 22, by the press service of the Federal Agency for Fisheries.

The water body is filled with the mollusk Anadara (scapharka), which is found in the seas of the Far East. This is the only bivalve mollusk that has a blood system. It is highly prized around the world, especially in Japan, and is considered a delicacy.

Conventional bottom dredges (a type of fishing vessel that drags a net through the water to catch fish. - Ed.) have proven to be ineffective for catching anadara. The clams have a knack for burrowing into silt, making them difficult to catch. This obstacle motivated the staff of the Azov-Black Sea branch of VNIRO to develop new experimental fishing gear.

In the summer and fall of 2024, the new devices were successfully tested in the Kerch Strait and the Sea of Azov. During the tests, the catches were dominated by anadara with shell length from 30 to 55 mm. This size fully meets the fishing standards.

Also scientists of AzNIIRH are actively working on technologies of processing of anadara, writes IA KrasnodarMedia. It is proposed to use methods of low-temperature cooking under vacuum (sous-vide technology) and production of products with high nutritional value - hydrolysates, sauces and pastes.

In addition, experts are studying the possibilities of enzymatic hydrolysis of anadara muscle tissue to produce antioxidant products. This will open prospects for the wide application of mollusks in the food industry.

Earlier "Izvestia" wrote that in the sea near Vladivostok recorded the appearance of microalgae psevodnitshii, which release a harmful toxin - domoic acid. It can get into the human body through eating sea delicacies. No dangerous concentrations have been detected in Russian waters, but there is a tendency to increase their density due to the increase in ocean temperature.
