Specialists of Transneft Kozmino Port have released 10 thousand specimens of Japanese scallop into the water area of Nakhodka Bay. The release was held under the supervision of representatives of the Primorsk Territorial Directorate of the Russian Federal Agency for Fishery and the Department of Ecology and Nature Management of Nakhodka Urban District.
The scallop juveniles with an average weight of 2-10 g with a total weight of about 100 kg were released into their natural habitat near Krylova Cape in the Sea of Japan. The valuable mollusk was grown at the mariculture area of a specialised organisation by the order of Transneft Kozmino Port.
The environmental event was organised in accordance with the Biodiversity Conservation in the Areas near Transneft’s Facilities Programme for 2019-2021.
In total, since 2017, the oil port has released 40,000 mollusks into Nakhodka Bay as part of the environmental activities.
Similar work was carried out at the mariculture area of the Kozmino oil port. More than 13 thousand scallop juveniles of the 2019 generation, having been gown in nurseries, were released to the bottom of the sea farm. Reproduction of biological resources is performed by the company as part of its comprehensive environmental monitoring.
“Scallops are an indicator of the quality and purity of a marine environment. With the help of scallops, we receive reliable information about the state of the water body near the oil terminal. This allows to control the impact of operational factors and therefore, prevent and reduce their impact on the natural environment. The result of the measures is the growth rate of scallop populations, which testifies to a favorable ecological situation in the Kozmino Bay water area,” noted Natalya Vykhodtseva, Head of the Environmental Safety and Rational Nature Management Section of Transneft Kozmino Port.
Japanese scallops belong to the scallop family; the species is one of the most commercially valuable invertebrates. It is a mollusk that grows in a bivalve shell. In Russia, the largest populations live in the seas of the Far East. Those include the coastal shallow waters of the Sea of Japan (down to 50 m) from Korea to Sakhalin and the Southern Kuril Islands.
The marine hydrobionts test ground area in Kozmino Bay was established by Transneft Kozmino Port in 2010. This is the mariculture area used for the implementation of a comprehensive environmental monitoring programme in Kozmino Bay using scallops and other valuable species of hydrobionts that live in the Far Eastern seas, including bay mussels, Japan sea tangles, sea urchins and Kamchatka crabs; experiments with algae castaria and ascidium purpurea are also conducted.
