According to the author of the project, head of the Centre for aquaculture and coastal bioresources of the National research center of marine biology Feb RAS Sergey Maslennikov, Russia this project is the first of its kind. It opens great prospects for the development of a new direction in aquaculture – reproduction of the crab, which is feasible in any fish and even the rice farm. You need to know, “RG”.
Sergei Ivanovich, it is still no one tried to raise the young of the crab?
Sergey Maslennikov: we Have two crab project. First, the research concerns the study of the mechanisms of reproduction, development of juvenile red king crab. Until we have a complete picture, it is impossible to give accurate predictions, and in the end crab fishery is very unstable. In 2020, we received 30 thousand copies of fry and now examine the factors of their survival. Projects with Kamchatka crab, we started back in 1996, and later worked together with VNIRO. Not long ago, one Japanese newspaper wrote that in Hokkaido with the support of prefectural government scientists have received 14 thousand fry of crab. It was presented as a great event. For us, our 30 thousand – working time, with us financial support only DVO ran.
the Experience gained in this and other mariculture projects, helped with the Japanese magnetoroton crab. Now on the Russian market is missing a key production technology of planting material monitoracao crab. This makes it difficult to start a new branch of aquaculture – the farming of freshwater arthropod.
Our project will teach you how to control all the processes, including the formation of pairs of parents, feeding of breeding stock. It is known that if the parent individuals are properly fed, they have produced fry will be more tenacious.
Monetarye – the crab grown in the world, which breeds in the sea but live in fresh water. Within two years it reaches marketable size, such as oyster, scallop, trout, or… lamb. It is absolutely standard agricultural cycle. Plus this crab is fairly undemanding, and all the farm animals. It can contain different climate and heat, and cold. Viable hatchlings will grow to marketable size in any point of Russia, as in separate reservoirs, and in fish farms – where the crabs can live on the bottom and eat the remnants of food for fish. It can be diluted even in the rice checks – crab-eating pests and weeds, but not touching the rice.
Not often heard, including from manufacturers of mariculture that to grow crab unprofitable.
Sergey Maslennikov: Profitable to catch all of the crab today, to put money in your pocket and not traitsI restore the population? Yes. But we deprive posterity of a natural resource, disturb the ecological balance.
the Population of Kamchatka crab ten times fell compared with the catches in the USSR. But when we proposed measures to restore, then heard the reply from the Agency that crab have a lot.
on the other hand, the state contains the factories involved in the reproduction of whitefish and sturgeon, though it is unprofitable by plants, because the direct of no return. But to restore this fish need: to sell caviar, you need to have the opportunity to show the resource. Of course, it is a national treasure, Russia is the only funding the reproduction of sturgeon in the Caspian sea. So, it is also profitable, but differently.
the crab the same as a salmon, a very clear migration paths: he returns to the shore, where they had been released during reproduction. By the way, the world’s first ringing of the crab, particularly Kamchatka, took place in the settlement of the southern Sea under the Discovery early last century. The crab is tagged and returned, so it has been proven that it makes sense to cultivate. But then, it allowed the level of development of science.
the Fact that the crab brings considerable profit, proven trading systems. If even five percent of the amount for the sale of the quotas went to the stock recovery would be great. Now, the government organized a small return on investment in the industry in the form of “quotas under the keel”, and partially funded the construction of the fishermen, the necessary next step.
Sergey Maslennikov: is a paradox: aquaculture is administered by the Ministry of agriculture, oversees her Agency and themselves maritimelaw referred to the fishermen… But all the characteristics of the industry: working with plantations, land reclamation, climate risks, production of planting material is a real agriculture.
If you buy a car for work in the field, I don’t pay him tax.
If you buy a boat for work on the sea garden, then no benefits you are not supposed to. Now in Russia the government is providing unprecedented support to agriculture (which gives the result), but not mariculture, although it has enormous potential. Land without exception, the ocean is unlimited. Almost all of the sea of Japan and southern Okhotsk seas is located in the favorable climatic conditions for the cultivation of aquatic organisms – scallop, mussels, sea urchins, crabs and others.
Despite the crisis phenomena in the economy, the industry is showing global growth to 20 percent a year. There is investment interest, and the need for quality products. From all areas of aquaculture production of marine aquatic organisms – the most profitable business. Studies show that profit generated by Marik��the culture can compete with microelectronics.
