For the past month or two I've been fishing on and off in the Wetlands (Baradin Bay) for about, on average, an hour a night. My goal has been to catch a Steelscale Crushfish and come up with an approximate catch-rate. Well...after quite a long while, my goal was finally realized.
As you can see, I unfortunately was not using Fishing Buddy. However, I can confidently say that catch-rate for me was approximately .001%. Hopefully this helps the fishing community a little. I urge others to attempt to catch this fish themselves, even though it can be terribly boring, and record their own catch-rates so we can finally know the exact catch-rate of this fish.
I also must say...holding the crushfish and old ironjaw while in my fishing outfit looks quite nice. =)
