North Atlantic mackerel has a reputation for being one of the hardest species to track, but GreenFish’s new artificial intelligence prediction tool is showing that even the most irregular stocks can be predicted with great accuracy.
GreenFish’s AI model draws on decades of satellite and fishing data, driven by one of the world’s most powerful supercomputers. The result is an eight-day forecast of the most promising fishing locations that automatically adjusts as ocean conditions change.
The company started with mackerel as it’s one of the most difficult species to predict. It was confident that if its technology could work in that sector, it could work anywhere.
“GreenFish technology is now being used by fishing companies across the globe, delivering predictions for a variety of species in oceans worldwide,” said GreenFish CEO Sveinn Sigurður Jóhannesson.
Building on this success, GreenFish is preparing to launch its commercial product for herring, followed by blue whiting and capelin for the North Atlantic fleet. Meanwhile, the company’s most popular offering continues to be GreenFish Tailored, a customised service that delivers exclusive predictions for clients in their specific fishing zones, whether targeting tuna, pelagic or demersal species. These forecasts not only identify catch locations but also predict fish size, quality and potential bycatch.
“With GreenFish Tailored, companies gain exclusive predictions for their fishing zones; insights that give them a competitive advantage,” Jóhannesson said.
According to Greenfish, by leveraging these predictions, operators can reduce search time, fuel use, and carbon emissions while improving quota fulfilment and catch quality. The result, it said, is greater value creation at a lower overall cost.
“Artificial intelligence is coming to the fishing industry, just as it has in many other sectors, bringing great value. AI is not a passing trend; it will only continue to advance. Companies in the fishing industry that recognise this shift and adapt will gain a competitive edge,” Jóhannesson said.
With its headquarters in Iceland and an office in Copenhagen, the company comprises a diverse team of experts, ranging from AI to space engineering specialists – all focused on helping meet the rising demands of the fishing sector.
