Every year, there are usually isolated reports of barrel jellyfish sightings on the Swedish west coast, but this year there have been significantly more sightings than usual. `There’s no doubt it’s a huge number,´ says marine biologist Martin Stjernstedt at Havets hus in Lysekil.
He has been seen in several places along the Swedish coast in recent days, but suddenly the alleged spy whale Hvaldimir appeard in the middle of Gothenburg's harbor.
In part two, we delve into the threats facing the small-toothed whales that inhabit Sweden's waters. Why are these porpoises becoming increasingly rare, and what steps can we take to address the issue?
SLU Aqua in Lysekil has for several years filmed bottoms in three different marine protection areas. Bratten is a Natura 2000 area far out to sea towards the Norwegian border. It is located in an area that is one of Europe's most fished places. Here it is possible to trawl right through the protection area, except in certain specific zones. Watch in the feature what it looks like on the bottom after a trawl has pulled out.
