China has successfully wrapped up an extensive fishery resource survey in the Indian Ocean, marking a significant milestone in the nation's understanding of offshore marine ecosystems.
The research vessels, Lanhai (Blue Ocean) 101 and Lanhai 201, completed their 110-day journey covering approximately 20,000 nautical miles and 103 sampling stations in the northwestern part of the Indian Ocean. This ambitious mission has filled a crucial gap in China's knowledge of regional fishery resources.
During the survey, the vessels cataloged and collected 112 species of fishery organisms, including notable species such as tuna and marlin. The research team gathered valuable data on upper-layer fish, cephalopods, crustaceans, plankton, fish eggs and larvae, as well as various water parameters. One of the standout achievements was the capture of an Indian Ocean sunfish weighing up to 500 kilograms, a testament to the survey's comprehensive scope.
Jin Yue, the chief scientist aboard Lanhai 101, highlighted the importance of these findings, stating, \"The collection of these species will provide vital support for the preservation of genetic resources and the cultivation of new varieties in the future.\"
Zhao Xianyong, a researcher at the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences, emphasized that the expedition not only bridged the existing knowledge gap but also plays a pivotal role in the sustainable development of offshore fisheries and the protection of marine biological resources.
Key samples from the survey will be transferred to the National Fishery Biological Germplasm Resource Bank for standardized long-term preservation, facilitating ongoing scientific research and the development of new aquaculture species.
The vessels involved are currently the largest and most advanced ocean fishery research vessels in China, boasting a length of 84.5 meters, a width of 15 meters, and a range of 10,000 nautical miles. Designed for durability, they are capable of withstanding harsh weather conditions and can sustain scientific missions for up to 60 days with a crew of 60.
Equipped with mid-upper trawl nets, as well as longline and squid fishing operations, these vessels are well-prepared to conduct comprehensive marine surveys, ensuring the collection of high-quality data and specimens.
