The Socio-Economic Relevance of Jellyfish – A Study by the Janus Project
Jellyfish populations have exploded in many Norwegian fjords in recent years. For more than ten years the inner Trondheimsfjord ecosystem has been dominated by the big jellyfish Periphylla periphylla. Fishing nets are filled with this species that currently has little economic value. Furthermore, removing jellyfish from fishing nets adds hours of work to the fisherman’s day.
