they did something similar like this in British Columbia with Salmon migration, due to the dams the salmons couldn't get far upstream for spawning so they made "salmon steps" lol

There is an increasing awareness of the problem of fish passage in New Zealand. These ropes are a cool idea for the species that are excellent climbers but not for inanga which comprise the bulk of the whitebait catch in many areas. The following report gives some good background on the abilities of New Zealand native fish to get past in-stream obstacles:

I thought inanga were able to climb these, which is one of the reasons they were so excited about them

I was talking to Bruno about them last November, and I remember he was encouraging a master's student to do something with them for her inanga/fishpass topic.

I know inanga are useless climbers, but I am mostly sure he said they could climb them (though probably not to great heights).

So exciting, as this makes a really easy way to improve bad culverts. I just hope it won't be seen as a way of avoiding putting in proper culverts. There are many other migratory fish that would be unable to climb them, but then again, if they were in a ramp, rather than hanging, it might work for most.
