Fast bescause you have to be fast when you are a trout and an ephemera is ther in front of you and food, because this is your lunch and you have to eat it! You have to slide in the water, to the exact point before the insects flies away, and sometimes you have to be quicker than the other trout around. Our friends from Bearnishfly did a great job filming this, they still are in the making of their new film, but since they’ve lost their camera, if you want to help them, join the kickstarter, so they can buy a new one and still feed us with those great films!
