The whole city. Hai Phong currently has 1,028 fishing vessels registered on the VNFishbase system, including 1,007 fishing vessels engaged in fishing activities.
With boats fishing far from the shore, a long tradition, fishermen often work in teams and when fishing at sea, they will often inform each other about the fishing ground to catch, improve fishing efficiency. extraction, reducing costs.
In recent years, due to a decrease in aquatic resources and an increase in the cost of going to sea, the traditional experiences of fishermen are no longer effective as expected.
Facing this situation, in addition to investing in increasing production capacity such as equipping new machinery and equipment with new technology and improving labor skills, fisherman's forecast information has received more attention.
Fisherman Dinh Van Ngoc, whose ship is anchored at Ngoc Hai fishing port, said that he has been at sea for more than 10 years, previously relying entirely on heirloom experience, but now has to rely partly on machinery and equipment due to natural resources. fishery profits decreased.
Therefore, when accessing information on fishing grounds, it has partly helped fishermen to be more convenient in fishing, contributing to reducing input costs, improving fishing efficiency in sea areas, and at the same time. is the basis for more effective fisheries management.
According to research, the forecasting of fishing grounds to exploit seafood resources has been carried out by the Fisheries Research Institute since 1996 until now, forecasting models have been increasingly improved and improved in quality.

Recently, many newly built seine and gillnet fishing vessels equipped with large capacity machines and modern fishing equipment such as motorized seine nets, using LED lights and fish detectors have increased the catches. . However, there are still many small floating fishing vessels that have not been equipped with equipment, so they mainly rely on experience, leading to unstable catches and not really effective.
Master Nguyen Hoang Minh from the Institute of Seafood Research affirmed that in order to bring about high efficiency in fishing, in addition to investing in modern technical equipment, a suitable workforce and management capacity, but also It is very necessary to contribute to fisheries science, in which forecasting fishing grounds is an urgent requirement.
Stemming from that practice, as well as to improve efficiency in fishing, in the period 2018 - 2021, a state-level project, research and forecast fishing ground for exploiting small pelagic fish resources in Vietnam has been completed. deployed.
After 3 years of implementation, the project has fully implemented the research contents, built, developed, perfected and updated the information system of the database for forecasting fishing grounds to exploit natural resources. Small floating fish in the sea of Vietnam.
“This study has helped to determine the relationship between the structure of hydrodynamic fields and the marine environment with the fluctuations of fishing ground for small pelagic fish in the sea of Vietnam and obtain an experimental model to predict the fishing ground. small floating fish in the sea of Vietnam", Mr. Minh informed.
In Vietnam, after more than 20 years of research, the scientific basis for forecasting fishing grounds has made significant progress. , because it reflects the relationship of fishing grounds, biology, and environment.
On the other hand, forecast bulletins are built on solid scientific bases, with oceanographic data and resources being updated continuously, ensuring practicality for fishing activities. of fishermen.
Forecasting the distribution of seafood resources and fishing grounds for marine fish and seafood species in order to improve economic efficiency, reduce fuel costs and time to detect fish channels is a priority research direction of many countries. , especially countries with offshore fishing fleets such as the US, Japan, Russia, France...
