Wold Fish Migration Day- 21st April 2018_Rafina River Results!

Results of World Fish Migration Day in Greece

April 21st 2018, Rafina, Attika Greece.

Our event was short but powerful. We had more than 35 participants including school kids and seniors and several more curious people dropping by throughout the two hour electrofishing and "wild aquarium" display.

After electrofishing just a 15 m. stretch of the stream, we set up two field aquariums to show-off the catch. And what a display it was!!!

Within minutes our team of experts set up some fantastic looking "wild aquariums" that hosted four fish species: two mugilids (mostly thick-lipped grey mullet Chelon labrosus), some huge eels and the river blennies. The last fish, Salaria fluviatilis, is a newly discovered species for Attika, a very important find for the Rafina River!

We also saw some fantastic birds and enjoyed unique urban river scenes. This river is a prime opportunity for restoration and conservation education.

Just some pics of the event...
