    Not sure where to post this?

    Have you seen any of these over there Matt? I’d think twice about swimming in this river!

    Not seen one yet Jim but I know they’ve had a massive effect on the native fish in the Ebro. Promised to take my Dad fishing there when he visits next so let’s see what we find.

    Hey

    Did you see ‘River Monsters’ on ITV this evening? Those Spanish Wels are certainly something special.

    I saw that program last night David, there are going to be some true monsters in the Ebro very soon at the rate they are growing /ohmy.gif” style=”vertical-align:middle” emoid=”:o” border=”0″ alt=”ohmy.gif” />

    I have been lucky enough to catch a Wells and even though it was only 50lb it still had a gob like a bucket and turned to bite my hand when released.

    Hey Mark

    It was very interesting how both of the Wels catfish that were caught tried to bite the angler upon release.

    I have seen large Wels in public aquaria, in Germany, but have never seen one caught on rod and line.

    Did the program mention the decimation of endemic species the release of this and other non-natives has caused in the Ebro guys?

    Hey Matt

    Yes it did mention the ecological implications.

    The programme on Thursday is all about Giant Gars in North America.

    Are you aware of any research covering this? It’d be good to have something to throw back at those who think it’s great having them there.

    Hey

    If I remember correctly it was a team of German researchers who released the original Wels into the Ebro. Because the dam water is hot these fish not only grew to mammoth size but have reproduced in large numbers.

    In Germany ‘Wels attacks’ on humans are usually in defence of fry. In this respect they attack the legs of swimmers.

    It’s not very well studied and having done a bit of research this morning it seems to be suspected rather than proven that the species is having a detrimental effect on native fish stocks, which just goes to show you can’t believe everything you’re told. here, here and here (scroll down past the Catalan in the last one).

    Having said that it’s still depressing how difficult it is to find a river or lake containing only native species here in Spain, see here and particularly here. Also this from 13 years ago in which recommendations were made but have not been followed, and this new one which shows the wels is still spreading.

    I also have a paper on decline of native fish species in Catalunya that isn’t available as open access if anyone wants it.

    Hey Matt

    Sadly similar stories emerge from all corners of the globe. As with the Killie group in Spain it is, mainly, small groups of dedicated people who fight to save endangered species of freshwater fish.

    I think I might have a baby in one of my tanks. Saw this strange cat with a big mouth in the local fish store and bought it. Was maybe 3 inches a month and a half ago and now is close to 10 inches.

    Have a more common baby giraffe cat I just got too:

    Best regards,

    The first one looks more like a Wallago?
