What's faster to bring in a steelhead a center pin or spinning or level wind reel? R you using strong enough fishing line or fighting them for a while? Im sure many have read this before but still seems important
HOW MANY WILD STEELHEAD DID YOU KILL THIS YEAR?
By Jeff Mishler
Let’s just say for the purpose of this piece that you’re a catch and release angler. You release all wild steelhead, salmon and trout because, well, it’s the law on most rivers here in the pacific northwest and more importantly, an angler concerned about the future of the sport, mostly likely, has come to realize that the future of any fishery lies in the preservation of genetic diversity which can only be ensured through abundant wild adult escapement. Releasing wild fish keeps the gene pool rolling along its natural way. And while some anglers are good at catching fish and others are not, it’s very probable that some anglers catch a lot of wild fish because they target them specifically; for whatever reason, they ignore the put and take fishery available to sport fishermen in most states and choose to pursue wild fish presumably using tackle and techniques that minimize mortality of the resource.
No angler of good intentions wants to admit that their catch and release routine, routinely kills wild fish. But these routines are often old habits passed down the family line and they can be hard to break, even if they negatively impact the resource we think we are protecting.
Consider the following scenario:
It’s early March. You and a buddy are drift fishing for winter steelhead on one of Oregon’s many coastal rivers. You hook six steelhead, land four and released all of them because most of the fish in the system at this time of year are in fact wild. Three of the steelhead you landed, you hooked drifting a pearl/pink corkie with a single hook and one of the steelhead was hooked after you threaded a sandshrimp under the corkie rig. Let’s say you are fishing from a drift boat. The water is high and off-color making it difficult to find a place to step to shore. So, for every fish hooked, you had to fight them longer than usual because the swift current made it difficult to bring the fish alongside the boat. Each fish hung in the current downstream from the bow until it was exhausted---In fact, that is when you lost the other two. You were certain they were ready, but they made one last turn away from the boat, towards the shore and the direction of pull on the line changed. The hook pulled free and those two got away---But not the other four. After three attempts, your buddy slides a net under the steelhead and hauls it into the boat. It flops around a bit but you eventually unhooked the size 1 bait hook from the corner of its mouth. You hold the steelhead up for a picture or two and then slide the fish over the side. You hold it upright for a moment because that’s what they say you should do to revive a tired fish, but it kicks out of your hand and swims off. Let’s just say the four steelhead you landed responded similarly. From your perspective, it would be reasonable to assume that all of the steelhead survived after release because they did in fact swim off on their own.
Could you believe that the opposite might be true? More than likely, all four steelhead died from a long-term, delayed mortality, a truth difficult for the angler to confirm because in most instances, death occurs hours, if not days later.
In the previous scenario, you, the angler, made specific choices that directly affected the overall mortality of catch and release fishing. What we do once the hook is set has more bearing on a wild fish’s survival than the gear we choose. Whether we fly fish only or pinch the barbs on our favorite plugs, equipment has little statistical impact on the overall percentage of mortality associated with catch and release---It is widely promoted that a fish hooked in the corner of the mouth or outside the mouth experiences a 3% chance of mortality if it is landed promptly, kept in the water and released quickly. The use of barbed or barbless hooks doesn’t seem to change that percentage significantly. Mortality is determined greatly by our behavior, or habits.
Dr. Bruce Tufts is a professor of biology at Queens University in Kingston, Ontario, Canada. He has studied the physiological effects of catch and release fishing since the late 1980’s. The findings from his research have helped shape catch and release regulations throughout North America.
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.
Tufts concluded, “…the brief period of air exposure which occurs in many “catch and release” fisheries is a significant additional stress which may ultimately influence whether a released fish survives”. According to Tufts’ study, any exposure to air significantly decreases a salmon, trout, or steelhead’s chance for survival.
In the above fishing scenario, how long would it take you to clear the net, unhook the fish, take the pictures and then put the fish back into the river? It is very, very difficult do it in less than a minute. I’ve timed numerous anglers trying to do exactly what I have described and in most instances, it takes two minutes or more once the fish is brought on board. So one might conclude that if 7 out of 10 rainbow trout die after an air exposure of 60 seconds, then 3 of the 4 steelhead netted and brought into the drift boat, died within 12 hrs after release.
Tufts states in a 2004, In-Fisherman, article, “When you remove a fish from water the secondary lamellae in the gills collapse, inhibiting gas exchange”. Tufts and I use similar analogies when trying to explain how detrimental it is to hold a fish out of water for long periods of time after landing it. Imagine running 100 meters as fast as you can and when you cross the finish line someone grabs you my the back of the head and forces it underwater for a minute. What’s your chance of mortality? Salmon, trout and steelhead breathe air about as well as we breath water.
Tufts states in an article published in, Atlantic Salmon Journal, Spring 2001, “There’s No Excuse Not to Stop Killing Salmon” that, “the studies have documented (delayed mortality) in salmon and other species…it is not something that occurs immediately after the period of exhaustive exercise…therefore not something that would be apparent to an angler releasing a fish. Delayed mortality can occur in fish that appear absolutely normal at the start of the recovery period.”
60 seconds out of the water and you’ve killed 7 out of 10 fish. This is somber news.
Additionally, Tufts does not take into account the cumulative affects of removing a fish’s protective slime by netting and bringing the fish on board, increasing the chance of bacterial growth on the skin after release and the accompanying increased stress levels. Nor does he address the mortality impacts of hook placement and the increased blood loss from the most vital organ, the gills, when a fish is hooked inside the mouth on a delicate gill rake. Some states have made laws requiring anglers to use single barbless hooks and to keep fish in the water at all times if it is to be released to reduce the chance for post release mortality.
The whether the capture of wild salmon and steelhead is intentional or accidental, catch and release fishing causes mortality at a rate higher than most well intended anglers could ever imagine. It is possible that the angler who chooses to target wild fish, kills more wild steelhead, salmon or trout than the equally effective angler who chooses his angling opportunities according to the run timing of specific hatchery returns and kills every legal hatchery fish he or she catches; the determinant being the combination of variables the angler has no control over, and a few that one does. If I catch 20 wild steelhead in four days of fishing and handle them carelessly, it is possible that I might have killed 14 of them, six more than the eight fish, four day limit of the angler whacking and stacking hatchery fish. One has to ask, whose behavior is better for the resource?
