Next time youβre out and about, walking or driving, have a think about whether there might be fish under your feet.
If you live in a New Zealand town or city, chances are that many of the streams that once flowed down forested hills and along swampy valleys are now running through pipes under suburban footpaths and roads.
We think of these pipes as storm water drains, but to fish they are still a stream.
And in Wellington, freshwater ecologists are discovering that eels and fish are definitely living in, and travelling along, these piped streams, which can run underground for kilometres.
