In The Field

The Migration of Invasive species into the Mediterranean is by now a fact, not a fear.
While it was important to understand migration patterns, how the distribution works exactly, by now it would appear the time to observe has passed. Numbers of the invasive Lionfish are exploding and we keep seeing more than 30 individuals in a single dive of 45 minutes. They are pushing local species out of their niches and feed on local fish stocks at a rate that does wear them down. Need to find out more about invasive species? Here is the explanation video!

Expedition Background

We hope to document and better understand the way new invaders in the marine environment impact the population dynamics under water. Keeping a close eye on the development of the fish stocks in certain key locations will be the main task of the expeditions along the way.
While lion fish do increase in abundance it is uncertain how strongly the negative impact on local fish stocks is, we hope to clear the mystery up a bit

Awesome project! I don't have invasive fish in my areas (yet).
Thanks for the comment @Robin G. where is your area at this moment?
Hi Manuel, I'm struck by the fact that there are lionfish in the waters around Crete. Do you know since when? I grew up on Crete, but live in the Caribbean now where lionfish are a huge problem and we try to control their populations by hunting them. Didnt realize they have invaded Crete too. Looking forward to hear more about the numbers you find. Good luck!
Hello @Michelle Achlatis!First sightings were made 2 years ago, last year seen on a regular basis but no more than 2 a dive. This years record is 32 lionfish in one single dive! Also in groups of up to 15 so far! Populations are certainly on a radical growth here
