It is foolish to apply Tufts study to Steelhead for the following reasons.http://forum.skagitmaster.com/index.php?topic=330.0
Here's the take away quote:
"According to Tufts, factors such as time out of water and length of fight combine to determine a released fish’s chance of survival. In his study, “Physiological Effect of Brief Air Exposure in Exhaustively Exercised Rainbow Trout: Implications for “Catch and Release” Fisheries”, Tufts studied the effect of time out of water periods of zero, 30 and 60 seconds for rainbow trout after exhaustive exercise. In 57-degree water, after 12 hours of recovery time, the control group-- fish that were held in captivity but not exercised--experienced no mortality. The group not exposed to air immediately after exercise experienced 12% mortality. The group exposed to air for 30 seconds after exercise experienced 38% mortality, and the group exposed to air for 60 seconds after exercise experience 72% mortality. 7 out of 10 trout died after 12 hours when exposed to air for 60 seconds."
Published this back in 2010. Bruce Tufts studies were not exclusively focused on Atlantic Salmon and I believe it is foolish to assume the steelhead are somehow unaffected by time out of water.
Rick for starters my reply was to the post that referred to Tufts study of the effects of air exposure of exhaustively exercised resident Oncorhynchus mykiss in context of the anadromous form and not Salmo salar. Second in response to your question, I will instead ask more to start. What makes you believe that as a human my tolerance for low available oxygen environments is the same as a fish? Second why did you neglect to add exhaustive exercise to your question?clarkii
the original link had nothing to do with the Tufts study but one that was related to atlantic salmon
but I will pose this - If I had held your head under water as a baby for a minute or held your head under water now for a minute - I expect your stress level might be the same!!!:razz:
