All the Stronsay alevins have hatched by now! This morning, only a few eggs were left on the mesh frame so it was decided to remove it altogether. Underneath, it was crawling with bright orange tadpole-like little alevins, similar to the one on the picture. They’re all very healthy and we will now keep an eye on their yolk-sacs. Another piece of good news: this morning, I found in my pigeon-hole the four Single Introduction Consents from Marine Scotland which allow us to release our alevins into the various lochs and burns!
The mesh has been removed and the alevins that were trapped are now free to move about. There has been no alevin mortalitys so far!
unfortunately, we found 25 dead alevins. hopefully now the water has been changed it will be ok.
