Hello #FreshwaterPearlMussel friends! This Microscope Monday 🔬 we have some fascinating photos of glochidia encystment on a brown trout.

An observation from the FBA Ark is that the growth of encysted glochidia is highly correlated to water temperature.

What's to be done about the River Wensum? It is sadly degraded from the biodiverse Chalk River habitat which my Gt Uncle Oliver (the Weston Fishery) knew 80 years ago. Even though it is a SSSI and a SAC. Strong words

💧 Toxic water at the EU Parliament today wasn’t just a stunt - it was a warning

As trilogue talks draw to an end, EU lawmakers must stand firm:
⚠️ No more loopholes
⏰ No more delay
🌍 Protect our rivers, our health, and our future

Pollution is real. Action must be too.

Let us know what you think⬇️

For Microscope Monday 🔬 please allow us to share with you some cosmic diatoms! These magical marvels feature in #Freshwater #Algae: Their microscopic world explored.

We're thrilled to have a limited number of this rare book still available in our shop:

Tabellaria. Eight-celled stellate planktonic colony.

Asterionella. If the cell at 7 o'clock reproduced, it would start a second ring of cells at a higher level than the first.
