There’s a really simple answer, if you go look at his study. He did it by tagging fish in the estuary, and collecting them at points where the salinity was known. He repeated the study in 2012 the same way.
She kept a few fish and put them into tanks with controlled salinity.
Exactly my point!
I think the difference here is that - she proved that they can survive in low levels of salinity, if they have no choice. He, on the other hand, showed that they will CHOOSE to go into areas with such low salinity, which IMO is a bit of an important distinction. And the only way to determine that is to do a long term study in the wild.
That’s not the only problem here. On her poster, she claims his original study only resulted in finding that the fish could live in 15 ppm, but in 2011 he originally found they could live in 8 ppm in a wild estuary.
Her study was for 6 ppm, and was in a tank.
It was completed in 2014 - after Jud’s second 2012 estuary study that examined fish at 6 ppm, 5 ppm, and 1 ppm. Her father, who was Jud’s former supervisor, probably knew about the second study - which wasn’t referenced by Arrington at all. So she didn’t just observe them a different way, she also excluded the fact that he had already found the results she was publishing as original.
