Squid die when they reproduce. We estimate that sinking squid carcasses locks away 11-12 Mt carbon/year in the deep oceans. Increasing squid fisheries interrupts this sequestration and sends it to our dinner plates - where it is respired to the atmosphere. www.sciencedirect.com/science/arti...

Sand is not just sand when you are a #sandeel.
Read about one of our studies that came out last year in JEMBE.

The sandeel's sense of sand
The sandeel plays an important role in the marine ecosystem as a key species in the food chain. Now research shows that sandeels are picky about the sandy bottom where they burrow – and this makes them vulnerable to potential changes to their habitats, which are sand and gravel banks.

We usually think of photosynthetic bacteria as the main N2 fixers in the world's oceans . Using a mechanistic model we estimate that heterotrophic bacteria are responsible for 10% of the global N2 fixation. And it also occurs temperate waters. www.science.org/doi/10.1126/...
Particle-associated N2 fixation by heterotrophic bacteria in the global ocean
Heterotrophic bacteria fix N2 in more diverse environments than previously thought, critical for the oceanic nitrogen cycle.

Jeg kan konstatere, at der er andre fagfolk i Sverige som er nået frem til samme konklusion som DTU Aqua.
HaV lukker fiskeriet efter stenbider (aka sjurygg) i alle svenske farvande fra 15. marts of frem.

HaV förbjuder fiske efter sjurygg
Från och med den 15 mars 2025 inte är tillåtet att fiska sjurygg i svenska havsområden. Beslutet innebär också att oavsiktliga bifångster omedelbart ska återutsättas och gäller tillsvidare.

Spændende artikel af Flora Juul Ørskov i Børsen om stenbiderens fremtid og fiskeriets udfordringer. Udover fiskeriet, så kommenterer jeg her lidt på, hvad jeg ser af forandringer, bl.a. klimaets betydning for stenbiderbestanden.
