“Batman has returned — the Batman River loach, that is.
For nearly five decades, ichthyologists — zoologists focused on fish — have been searching for the loach.
They’ve scoured shallow, rocky and fast-flowing parts of rivers, the fishes’ favorite climate, using tightly woven nets meant to catch tiny critters, according to Shoal, a London-based conservation initiative involved in these efforts. The Batman River loach was one of Shaol’s “10 Most Wanted Lost Species” of fish that its partners prioritized trying to find.
And then — they did.
On a recent expedition, 23 fish turned up in the nets of Cüneyt Kaya, a fish taxonomist, and Münevver Oral, a geneticist, who had been working to narrow down possible streams where the fish could still be.
“I’ve been researching this area for 12 years and this fish was always on my wish list,” Kaya, an associate professor at Recep Tayyip Erdogan University, told the Guardian. “It’s taken a long time. When I saw the distinctive bands on the fish, I felt so happy. It was a perfect moment.”
Kaya and Oral told the Guardian that more work needed to be done to analyze the existing loach communities and what threats they face.
Loach, due to their size, were never commercially fished by humans, whose heavy consumption of other fish species has contributed to their depletion.
But the scientists do suspect that the construction of the Batman Dam in the 1980s and ’90s, along with pollution, drought and invasive species, probably led to the fishes’ decades-long disappearance….”
