Rangers Mirella Pomeroy and Myles Riki were out in Saltwater Forest on the West Coast last week completing the local annual mudfish (Neochanna apoda) survey.
Mudfish are under increasing threat from habitat loss, so to find them thriving in Saltwater Forest is a really positive sign.
Mirella found out what the bigger ones have been eating:
“We caught this one mudfish, which we thought was pregnant because it had a really big belly. Then we picked it up for a closer look… and it regurgitated (“blleeerrrgh”) a juvenile kokopu into Myles’s hand.”
You can find more information about mudfish and New Zealand’s other freshwater fish species on the DOC website.
Meet Teviot flathead galaxias, one of the five species of New Zealand native freshwater fish, whose threat of extinction has recently been listed as nationally critical—the highest threat category…
Gulp, gulp… I’m Teviot flathead galaxias, but you can call me Tev.
I live, with every other Teviot on the planet, in a small part of the Teviot River in Otago… gulp, gulp.
If you think that sounds crowded you’d be wrong. There aren’t that many of us. Probably less than 100. So, it’s actually kinda lonely.
I may not be as famous as Sirocco the kākāpō (…yet), but some of my family are quite well known. Unfortunately for them though, it’s for how they taste in a fritter… gulp, gulp.
I am every bit as threatened as my feathery friend though. We’re both classified in the New Zealand Threat Classification System as ‘nationally critical’—that’s just one step away from ‘extinct’… gulp, gulp.
It’s tough to be a small fish like me, as there are many threats to my home, including land use changes, gravel extraction, water abstraction, drain clearing and declining water quality… gulp, gulp.
On top of all this, introduced trout—who are a lot bigger than me—think I’m quite tasty… gulp, gulp—just like you humans with your whitebait fritters.
I think there’s room for us all—native fish, trout and humans, but we fish rely on you humans to talk to each other and work together to come up with ways to keep our rivers and lakes clean and beautiful and, importantly, to keep me off the ‘extinct’ list… gulp, gulp.
