In recent times, fishermen in Hau Loc, Hoang Hoa, Quang Xuong districts, Nghi Son town and Sam Son city have invested in applying Sonar horizontal detectors, journey monitoring equipment, PU foam storage tanks, and fish-attracting LED lights on fishing vessels... According to the captain of the TH 9354 TS ship Le Van Tri in Hoang Truong commune (Hoang Hoa), using a horizontal detector is an advanced device with a detection radius of 2,000m, helping to control the water around the ship and detect schools of fish far away from the ship. Thanks to modern fishing equipment, fishermen no longer have to grope around to find fish streams like before. Therefore, applying Sonar horizontal detectors in fishing has improved productivity, with output increasing from 1.5 to 2 times compared to before use.
In addition to being used in seafood exploitation to increase productivity, the Sonar horizontal detector also integrates many functions to support fishermen, such as positioning, determining depth, obstacles under the sea...
Previously, when going out to sea to fish, many vehicles often lost signal and could not contact their families and the shore stations of the fisheries industry. However, since fishing boats of 15m or longer have been equipped with voyage monitoring equipment, the signal is updated to the mainland 24/7. All fishing logs are updated on the system and fishermen can easily check them in the phone application, thereby having an effective fishing route. In addition, when encountering adverse weather or fishing boats in distress at sea, the positioning device will quickly send out support signals, and rescue forces will easily find the exact location of the fishing boat.
Mr. Pham Van Hoa, owner of fishing boat TH 90195TS, capacity 370 CV in Quang Tien ward (Sam Son city) said: Since installing the journey monitoring device, there is no need to follow the fishing boat out to sea. With just a smartphone with Internet connection, the boat owner at home can still know the exact location of his boat at sea. Once the fishing boat comes to exploit in an unauthorized area, the fishing boat positioning device will send a warning signal so that we can control the fishing area.
With the benefits of installing voyage monitoring devices on fishing vessels 15m or longer, to date, fishermen in localities in the province have installed voyage monitoring devices on 1,121/1,144 fishing vessels, reaching a rate of 98%. In the management of fishing vessels, by June 15, the whole province had updated registration data, inspection, and issuance of fishing licenses for 2,493 vessels into the National Fisheries Database System (Vn - fishbase). Of which, 598 fishing vessels have a length of 6m to less than 12m, 1,895 fishing vessels have a length of 12m or longer.
Mr. Le Van Han, an officer of Lach Hoi Fishing Port Management Board, said: The Vn - fishbase system is an online and synchronous database for managing information on fishing vessel registration, inspection, fishing quotas, fishing licenses; data on fishing ports, storm shelters; data on logs, fishing reports; confirmation of exploited aquatic materials; certification of the origin of exploited aquatic products... This is a fairly comprehensive database and has become a useful tool in fisheries management and seafood exploitation capacity. Every time a ship docks at port, fishermen carry out procedures to certify the origin of exploited aquatic products, just need to enter the fishing vessel number into the Vn - fishbase system to know the journey of the fishing vessel at sea, to serve as a basis for confirming the origin of aquatic products. Through the Vn - fishbase system, the goal is to monitor and manage 100% of the digital information of fishing vessels' activities from exporting fish to fishing, docking at ports to unload products, to registration as well as the fishing and trading data system of fishermen. The application of the Vn - fishbase system also helps people to conveniently monitor information and save costs in seafood exploitation activities.
Currently, along with the application of digital transformation in seafood exploitation, many fishing vessel owners have invested in product preservation technology. Most offshore fishing vessels in coastal localities of the province have invested in the application of product preservation cellar technology using stainless steel and polyurethane (PU), especially logistics fishing vessels, bringing good efficiency. Many offshore fishing vessels use ice technology made from seawater to preserve seafood and are equipped with machines to filter seawater into fresh water.
