The two scientific research vessels "Blue Ocean 101" and "Blue Ocean 201" independently built by my country have recently returned to their home ports of Qingdao and Shanghai after completing a comprehensive survey of Indian Ocean fishery resources.
At the Qingdao home port terminal, the reporter saw that the tuna and other fish specimens caught by the "Blue Ocean 101" research ship were being lifted to the shore by the ship's crane. It is understood that my country’s competent authorities have notified relevant regional fishery management organizations in advance of this entry into the high seas of the Indian Ocean to conduct a professional survey of fishery resources in accordance with international contract compliance requirements. More than one hundred scientific researchers in our country have achieved fruitful scientific research results after more than three months of maritime scientific surveys.
Li Lingzhi, chief scientist of the "Blue Ocean 201" voyage: This survey of fishery resources in the high seas of the northwest Indian Ocean lasted 110 days, with a total voyage of about 20,000 nautical miles. A total of 103 stations were surveyed and sampled, and a total of tuna, swordfish, and swordfish were collected. 112 species of fishery organisms.
Through the survey, the researchers obtained resource data on pelagic fish, cephalopods, and crustaceans in the surveyed sea area. At the same time, data and samples such as plankton, fish eggs, larvae, and hydrological environment in the surveyed sea area were also collected.
Zhao Xianyong, a researcher at the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences: This survey has filled the gaps in China’s previous scientific surveys of distant-water fishery resources in the high seas. It is of great significance to the sustainable development of distant-water fisheries and the protection of marine biological resources.
It is understood that "Lan Hai 101" and "Lan Hai 201" are my country's largest tonnage and most advanced comprehensive survey ships of distant-water fishery resources. The ships have a total length of 84.5 meters, a width of 15 meters, and a endurance of 10,000 nautical miles, which can meet the global unlimited navigation zone. Navigation requirements in sea areas (except ice areas).
Jin Yue, chief scientist of the "Blue Sea 101" voyage: The "Blue Sea 101" scientific research ship is a 3,000-ton survey ship equipped with advanced nets, instruments and equipment. The ship has strong wind and wave resistance, a self-sustaining capacity of 60 days, and can accommodate 60 people for scientific surveys. It also has mid- and upper-level trawls, as well as longline fishing, squid fishing and other operating methods for surveys.
Important samples will be transferred to the Fishery Biological Germplasm Resource Bank
It is understood that the "Blue Ocean 101" and "Blue Ocean 201" comprehensive survey ships simultaneously went to multiple sea areas of the Indian Ocean to carry out comprehensive scientific surveys and obtained a large number of marine biological specimens. This provides a rare sample resource for Chinese researchers to conduct research, development and utilization of ocean biological samples.
During the collection process, the staff captured the largest fish in the Indian Ocean - sunfish, weighing up to 500 kilograms. In addition, during the investigation, rare protected creatures such as turtles were occasionally captured, and the staff released them immediately.
Jin Yue, chief scientist of the "Blue Sea 101" voyage: Some of these species are highly migratory species and are distributed in temperate and tropical waters around the world. After harvesting these species, they can provide a very important support for our future preservation of germplasm resources and the cultivation of new varieties.
It is understood that the large number of marine animal specimens obtained during this survey have filled my country's gaps in the collection and preservation of fishery organisms in the Indian Ocean. In addition to conducting biological measurement studies on these samples, important representative samples will also be transferred to the National Fishery Biological Germplasm Resource Bank for standardized long-term storage for scientific research and the development of new breeding species.
Shao Changwei, a researcher at the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences: The samples taken from the high seas this time can evaluate the genetic diversity of samples taken from different geographical areas. The genetic diversity can be used to evaluate the quality of its germplasm. bad. (CCTV News Client)
