Picture: Louis Cahill
Louis Cahill, over at Gink & Gasoline, simply wrote up an interesting story about steelhead mortality. Now, his story is anecdotal (the knowledge he shares was shared to him by a pal) but it surely passes the scent check.
It goes like this—is it doable to kill a steelhead with out realizing you had been the one who dealt the fish its last blow?
To know how that’s doable, it’s essential hear the story Louis’s pal advised him
Some scientists needed to tag steelhead to trace their actions, in order that they set out with fly rods to catch a couple of, insert the tags, and allow them to free. Nevertheless, as soon as they seemed up the tag information, they observed one thing alarming.
“Inside two hours lots of the fish they’d tagged, and launched in good well being, had been useless,” Cahill wrote. “They collected the fish and carried out autopsies to find out what had gone fallacious. In each case the reason for loss of life was head trauma. It seems that ‘steelhead’ is a misnomer. The fish’s head is, in reality, its most weak spot.”
Head trauma, as Louis factors out afterward within the story, is feasible if the steelhead is landed in shallow water, the place it has the possibility to thrash round and knock its head on rocks. With out the depth and rush of water to comprise the actions, even when the steelhead is in a internet, it will possibly nonetheless knock its head on rocks and probably trigger mind harm.
There’s a bit extra to it than I’ve described right here, so it’s value studying all of Louis’s story, which you are able to do here.
