We have uploaded an English subtitled version of the stream fishing trip video that we filmed last summer on YouTube.
The fishing trip was short due to unfortunate rain, but Field Staff member Shinjiro Kinoshita explains about single asssit hooks for minnowing in mountain streams in an easy-to-understand manner.
[Trout Native] Standard Single Hook Selection for Mountain Stream
Shinjiro Kinoshita mainly uses the looped-eye hook he made himself using DRB-46F.
This is a very informative explanation of hook size selection in relation to lure size, and the approach that only the single assist hook can provide.
Enjoy the video!
