Submersed Aquatic Vegetation Enhances Density and Diversity of Epifaunal Invertebrates Compared to Filamentous Mats in the Central Baltic Sea This study evaluates the relative importance of Submersed Aquatic Vegetation (SAV) and filamentous mats in shaping epifaunal invertebrate communities in the central Baltic Sea. Our results showed tha....

Submersed aquatic vegetation (SAV) enhances epifaunal diversity & abundance, esp. grazers. 🌱🐌🐚🌊Filamentous algal mats mainly increase gastropod populations. Protecting SAV & reducing eutrophication are vital for sustaining Baltic Sea invertebrate communities.

Sweden sets an example for EU countries with first steps to ban bottom trawling in marine protected areas Swedish government proposal to amend legislation, paving the way for a future ban on bottom trawling in Swedish marine protected areas.

Bottom trawling, dragging a heavy net across the seafloor, has been compared to burning down a forest to catch rabbits.

Sweden starting to ban this in sensitive habitats is my #EarthOptimism #OceanOptimism for today.

(I’m not anti-trawl but there are some places we shouldn’t do it)

Great Colin that a PhD position is coming out for pink salmon work. We need more of these around Europe!

Fantastic PhD opportunity to study invasive Pink salmon with a geniune multidisciplinary team - if you have skills in fish ecology, stats and/or social science then move quickly to apply. UK and non-UK students welcome. Please forward.

Great work by Karen Dunmall explaining our new paper on Pink salmon and range expansion, selected by ICES Journal of Marine Science as their Editor's Choice this week. Liking the video explainer that accompanies these papers.

Where the Rivers Run Pink Non-native pink salmon have swarmed Norway’s rivers, prompting a relentless—and potentially fruitless—fight to beat back the invaders.

A pink salmon with a Grinch face; the text says "December 13"

Pink salmon is the smallest Pacific salmon species (the genus Oncorhynchus) found in North America, often weighing <5 lb (2.2 kg).

“Oncorhynchus” comes from the Greek onkos ("hook") + rynchos ("nose"), in reference to the hooked jaws males typically develop in the spawning season #25DaysofFishmas

Sharing this photo of a native oyster bed in one of our survey sites here for the first time. This was my coelacanth moment, especially as many deny these oyster habitats even exist. Same as eels, Ostrea edulis (the species and the habitat) are threatened and yet we keep managing them as a fishery.

Can you add me in please? Cheers

European gudgeon (Gobio gobio)

Exotic European gudgeon is replacing Italian gudgeon in Italian streams and rivers. We tested interspecific differences in the lab. The smaller Italian gudgeon displayed lower maximum swimming speed and substantially higher sympatric mortality. Recent paper here: www.tandfonline.com/doi/full/10....

Salmon maps made by @lukefi.bsky.social are now online for wild salmon rivers in Finland! You can view distribution areas and monitoring sites in the Luonnonvaratieto website.

Time series of collected data is being made available too.

After 100 years, salmon have returned to the Klamath River – following a historic dam removal project in California After being absent for more than a century, salmon have been spotted in Oregon's Klamath River Basin, following a mammoth dam removal project in California.
