1.Friday’s 🧵is all about Eels. The species we have in 🇮🇪 is Anguilla anguilla, the #EuropeanEel, not to be confused with other Anguilla species (such as the American eel), or indeed the mighty Congor eel (Congor congor). The photo is a bit blurred because....😱 
2.European eel can be found in almost every stream and river in Europe, from the top of Norway, to the bottom of Spain, and also along the coast of North Africa
3. Eels are catadromous which means that they spawn in the sea, and then travel back to freshwater. (Anadromous species like salmon and trout spawn in freshwater before migrating to the sea) Thanks to Filipe Romão for this informative infographic
1. Good morning ☀️ Thursdays 🧵is about #Trout
For clarity, we are talking about Salmo trutta, the native trout to Ireland, which can be either resident (brown trout) or migratory (sea trout) or many things in between 📸 G. Rogan

@TheFSBI 2. Trout display phenotypic plasticity. A phenotype is a set of observable characteristics or traits of an organism ➡️what does it look like and how does it function? Here’s various L. Melvin trout, thanks to A. Ferguson & P. Prodöhl @QUBelfast

@TheFSBI @QUBelfast 3. For trout, the decision to stay put in freshwater, or migrate to sea is complex, governed by genetics, the condition of the fish, and environmental conditions. This is an excellent infographic also from Andy and Paulo @QUBelfast , + Tom Cross, @TomEReed & @mcginnity_p @uccBEES
1. Hi everyone, I’m Elvira de Eyto @edeeyto , and this week I’ll be talking about long term monitoring, freshwater ecosystems, migratory fish and a bit about freshwater pearl mussels. I work at the research station in the Burrishoole catchment run by the @MarineInst
@edeeyto @MarineInst 2. I grew up near Navan, Co. Meath, spent a good bit of time in @TCDZoology doing a degree in natural sciences followed by a PhD and subsequent research work on the ecological assessment of lakes
How can we tell what condition a lake is in ?💦
This is the beautiful #LoughCarra

3. I did my PhD with 3 partners-in-crime @gnfree_gf @J0naf1n and Rossana Caroni, and we spent 2 years driving around 🇮🇪 with a little inflatable boat sampling many many many lakes. No camera phones in those days! 📸These are literally the only 3 photos I have of those 2 years
