Trawling in the Koster Sea - Sustainable fishing from Lagunen & Koster

Explore the unique world of sustainable fishing in Kosterhavet


In the heart of Kosterhavet, you’ll discover not only the beauty of nature but also the dedicated work of fishermen striving to preserve the prawn stocks and create a sustainable future. Over the decades, they have developed innovative and selective gear to ensure a fishery that respects the sea’s resources.

Join us on an archipelago experience that is as educational as it is magical—an encounter with a living tradition where only the amount of prawns that can be sold are brought up. Here, sustainability is a way of life and every detail is carefully considered.


An exclusive archipelago tour few can offer

We set sail towards the Kosterfjord, where we meet a local trawler in the middle of a classic “haul,” as it’s called in Northern Bohuslän. We follow the fishermen’s work up close, from the moment the trawl is pulled up until the catch comes aboard.


When the trawl lands on the fishing boat, we get the unique opportunity to board and share the catch—you’ll be served the freshest prawn you have ever tasted, straight from the sea! Together with delicious accompaniments, we enjoy a culinary experience that enhances this already unforgettable day.

Tailor-made experiences outside the schedule

On this journey, we cooperate with local prawn fishermen who share their stories and passion for sustainable fishing. For an even more personal touch, this tour can be booked as a private charter all year round, outside of our regular schedule.
