I just ran across a video by accident thatís pretty interesting, and the first time Iíve seen biologists talk about it. I donít remember how long ago I learned that itís easy to calm most relatively ďgreenĒ saltwater fish so that they donít hurt themselves or you.
I donít remember who told me about it either, but it was somebody much older than me a long time ago. It is not just sharks that this technique seems to work on.
Incidentally, the fish below was caught on a heavily weighted fly at the insistence of my buddy. We were sailfishing, drifting a live ballyhoo teaser and not having any luck raising sails. He'd been marking kinfish on sonar every drift, and insisted I sent a fly down to them weighted down with big split shot on an 8 wt. he keeps aboard.
He claimed that the commotion of a kingfish fight would stirr up the sails. That was the start of out 4th drift along the same line, and five minutes after the below pic, I hooked a sail he reised on the teaser. Coincidence? Maybe, but I doubt it. He knew I was not keen on wasting time when sailfishing. Early and late have always been the most productive times near the reef edge.
The video below will start at a pertinent place Ė though the entire video is very interesting.
It might be worth a try on freshwater fish that have to be handled in order to be de-hooked.
