Gullmar Fjord’s 2027 Trawling Ban: How Scientists Will Watch the Seabed
A fjord is about to change one rule. Scientists are already getting their muddy buckets ready, so they can see what the seabed does next.
Bottom trawling will be banned in protected Gullmar Fjord from July 2027, the University of Gothenburg reported on 4 June 2026. Before that date, its researchers are collecting seabed samples, so they can compare marine life before and after the change.
So the story is not “the fjord has recovered”. The watching is only beginning, and that is the interesting part.
What is a seabed sample?
Researchers lower a grab sampler to the bottom. It closes around a small area of sediment and brings it up. They sieve the mud and identify the animals inside, such as worms, snails and brittle stars.
It is a tiny piece of a huge underwater landscape. So the team repeats it across many sites and many years, and the record grows longer.
In 2026 the team planned 40 extra samples in Gullmar Fjord, as part of the preparation for the ban.
Why does a baseline matter before the trawling ban?
To know whether a rule changes seabed life, you need a picture of “before”. Scientists call this a baseline.
The annual marine monitoring programme has sampled some sites since the 1970s. The researchers say the long-term trend in seabed species richness has generally gone down. They also say natural variation matters, because the sea changes from year to year on its own.
A fair comparison needs repeated measurements. One muddy bucket cannot tell us the future of a whole fjord.
How to read the news
Be gentle with big headlines. No recovery has been shown yet. The ban is planned for July 2027, and the real answers will take years of sampling.
Dates and rules can change, so check the latest official news before you rely on any date.
What visitors can do
Gullmar is a protected fjord with a rich underwater landscape. Follow local boating and nature rules, and avoid disturbing wildlife or seabed habitat. Rules can change, so check locally.
The Eye of the Fjord live cameras at Kristineberg are a very low-impact way to watch some of the life below the surface. Our Sweden ocean guide has more places and stories.
In July 2027 the rule changes. The best part may be the slow, careful years of watching what the seabed does next.
Questions people ask
When will bottom trawling be banned in Gullmar Fjord?
The University of Gothenburg reports that bottom trawling will be banned in protected Gullmar Fjord from July 2027. Check local sources for the latest rules.
What are researchers measuring?
They collect seabed samples with a grab sampler, sieve the mud and identify animals such as worms, snails and brittle stars. They plan to compare marine life before and after the ban.
Has the seabed already recovered?
No. The monitoring is just beginning. Scientists hope sensitive species such as sea pens may return, but that is a prediction, not a result yet.
How can I enjoy the fjord without harming it?
Follow local boating and nature rules, and avoid disturbing wildlife or seabed habitat. The Eye of the Fjord live cameras at Kristineberg are a very low-impact way to watch.
Wildlife encounters are never guaranteed and never forced. Ocean Calling works only with vetted, ethical local operators, and every animal is free to approach, or not, entirely on its own terms.
