The use of video surveillance, digital monitoring and sensor technologies is expanding across an increasing number of economic sectors in the United Kingdom. These innovations are
becoming particularly important in industries where transparency, regulatory oversight and environmental protection are essential. Fisheries are one such sector, having traditionally played an important role in the UK government's food security and sustainability policies.
The British government is now taking further steps to modernise fisheries management by introducing mandatory electronic monitoring systems for large fishing vessels operating in English waters. The initiative is designed to improve the protection of fish stocks and marine wildlife while ensuring that fishing activities comply with environmental regulations.
According to an announcement by the Department for Environment, Food and Rural Affairs (Defra) on 9 November 2026, large pelagic fishing vessels will be legally required to carry Remote Electronic Monitoring (REM) equipment from November 2028, subject to parliamentary approval and legislative timetables.
The technology combines cameras, sensors and GPS systems to provide a continuous record of fishing activities at sea. It allows authorities to establish where vessels operate, what species they catch and whether protected marine animals, including dolphins, seabirds and sharks, are accidentally caught during fishing operations.
The new requirements will primarily affect large pelagic trawlers, which specialise in catching shoaling fish such as mackerel and herring in open waters. These vessels operate on an industrial scale and can handle substantial catches, making effective monitoring particularly important for maintaining sustainable fishing practices.
Fisheries Minister Stephen Morgan described the initiative as a significant development in the government's efforts to protect marine ecosystems. He noted that many fishing vessels have already voluntarily installed REM systems, demonstrating growing acceptance of technological solutions within the industry.
The new legislation will therefore bring the remaining large pelagic trawlers into the same regulatory framework, creating more consistent standards across the sector. It is also intended to establish fairer competition by ensuring that all major operators are subject to comparable monitoring requirements.
Beyond enforcement, the government expects the technology to provide valuable scientific information. Data collected through cameras and sensors will help researchers develop a more accurate understanding of fish populations, monitor changes in marine ecosystems and identify fishing practices that could threaten biodiversity.
For regulators, continuous electronic monitoring should make it easier to identify potential violations and respond proportionately to harmful or illegal activities. This could also improve the quality of decisions concerning fishing quotas, conservation measures and the long-term management of marine resources.
The policy follows a successful trial conducted by Defra in cooperation with a volunteer pelagic trawler. The project tested the practical application of REM technology at sea, and the experience gained during the trial helped shape the government's decision to introduce the mandatory requirement.
The initiative reflects a broader transformation in the UK's approach to economic regulation, with digital technologies increasingly being used to improve accountability and the sustainable management of natural resources. In fisheries, the introduction of electronic monitoring is expected to strengthen environmental protection while supporting the long-term viability of an industry that remains important to Britain's food supply.
Ultimately, the government's objective is to combine technological innovation with responsible fisheries management, ensuring that the exploitation of marine resources does not undermine the health of the country's seas or the future of the fishing industry.
