In the years since Kokanee University was written, many wonderful developments have happened. The tackle designs, for example, are way different now as technology has made available vast improvements in action and color. What has not changed are the concepts outlined in previous articles. Let’s take a look at fishing strategies to catch more kokanee!
Color Fish Finder
No doubt, the very best piece of electronic equipment is the color fish finder–sonar. Color is better because of the unique biology of the kokanee, which have an unusually large air sac, and sonar cannot penetrate air. Because of this, kokanee can be seen on the fish finder, usually as bright orange (the default color on many systems). No other freshwater fish has this distinct detectable characteristic, so you can easily tell the depth of kokanee by this method.
The fish finder will let you know the current depth. Knowing the depth of the bottom is essential, especially if your lake has varying contours. On more than one occasion, I have raised downrigger balls “just in time” to avoid getting hung up on a bottom that suddenly came up, seemingly out of nowhere. Your fish finder will track your downrigger ball, and you can use this to verify the accuracy of the counter on the downrigger.
One factor to consider is how large a viewing area there is. The larger the viewing area, the higher the cost. Screen resolution is another factor to consider – will your viewer be viewable in sunlight and with polarized sunglasses? Another critical factor is the location of the fish finder in relation to where you are sitting while fishing. You need to be able to see the details on the screen.
GPS
GPS serves many useful functions. One of the best is showing accurate boat speed. (The little paddle wheel on the fish finder is unreliable and next to useless.) If you are targeting a speed of 1.4 MPH, you will be able to know when you are going 1.4 MPH. You will also be able to know when you are NOT going 1.4 MPH.
GPS will display a track of where you have been, and the memory will store those tracks until you erase them. I have had these tracks for years on the same device, showing both where I have been and also where my favorite and most successful areas have been.
Another fabulous feature is the cartography, which shows the contour depths of the lake you are on. You can either purchase the SD card, or many now come with the cartography pre-installed. My SD card covers all the lakes in the western US. You can get these cards to cover your region as well. Knowing the depth contours is a tremendous help. For example, it will allow you to stay on course within a former river channel. It will show points of land that are underwater and which could be a problem in navigation when the downriggers are out.
Temperature At Depth
One of the very best recent developments in technology is the ability to accurately measure the temperature of the water at depth. While the temperature function on your fish finder only tells you the surface temperature, the simplest device for measuring water temperature at depth is from FishHawk Electronics.
This little device is called the FishHawk TD. It is easy to use by simply attaching the device to your fishing line, pressing START, waiting for READY, then lowering it into the water. I send it down deep, then retrieve it, then press view, and it shows the water temperature in 5-foot increments down the water column as far as you have lowered the probe. This is extremely useful, particularly when looking for that 54-degree temperature depth in kokanee season.
I have also used the device to understand what was going on underwater. During one early September outing on a high mountain lake, I could see on the fish finder a few scattered kokanee at 40 feet, and a whole bunch of kokanee at 60 feet. Try as I could, no kokanee could be enticed from the 60-foot depth. The kokanee at the 40-foot depth were the only ones that would bite. I set out the FishHawk TD to determine if temperature had anything to do with it. Sure enough, it did.
The fish at 40 feet enjoyed a temperature of 54 degrees. The fish at 60 feet were at 44 degrees. The deeper fish were already starting to settle in for the winter. Since it was September, I could tell these were the two-year-olds (next year’s fish). Most of the kokanee I had caught at the 40-foot level were either turned or were turning color. By combining what I learned from the temperature measurements with what I saw on the fish finder, I was able to figure out why I was not getting bit at the deeper depths.
Electric Trolling Motors
The single best advantage of the electric trolling bow-mounted motor is the ability to steer the boat by wireless remote control from wherever you are in the boat. I simply strap the small control on my wrist, and that lets me easily control the boat’s direction and speed, even when I am fighting a fish or setting the downrigger.
Scouting A New Lake
Once you have enjoyed some success fishing for kokanee, you can have confidence in fishing any lake with a kokanee population. Kokanee are kokanee regardless of whether they are in Oregon, Idaho, Montana, North Carolina, British Columbia, Washington, Colorado, New Mexico, Utah, Wyoming, or California. When I know I am going to fish a new lake, the very first thing I do is to find the lake using Google Earth. I need to know the shape of the lake, where the deep water is, and where the shallow water is. I need to know what feeder streams come into it and where the outlet(s) are. I need to know the structure of the surrounding terrain, such as whether one side coming into the lake is steep and the other side is gentle.
I also check out the lake using my GPS cartography. I can sit in my boat in Central Oregon and study lakes in any other location simply by moving the cursor on my GPS.
Generally, what I am looking for is where the current might be and where feeder streams come into the lake. Those are two locators of what I call “active” water. This is where water mixes with the regular lake water, adding oxygen to the water. Fish need oxygen. This is also where trace nutrients come into the lake from feeder streams. These nutrients act like fertilizer to the plankton (phytoplankton) that the zooplankton, kokanee, and other baitfish feed on.
I look for drop-offs, where the lake suddenly gets deeper. Recall that as you go deeper down the water column, the water gets colder. It cannot get colder unless it gives up heat that rises to the surface. This process causes mixing – water movement up and down. This process is also good for the plankton and, hence, good for the kokanee.
If I am fishing early in the season, I look for structures, such as points of land coming into the water. I have found that in the early season, kokanee relate to structure.
Finally, using the internet allows you to research in ways we never could years ago. Don’t limit yourself to fishing forums. Searching and finding hidden gems can give you inside information that many anglers have overlooked.
The whole idea is to learn as much reliable information about the new lake as you can from the available sources. Be assured, what has worked for you on your local lake will also work on the new lake.
The Science Of “Scent”
All fish have nares, which are scent-detecting tubes on the snout of the fish. A fish’s ability to detect scent is flat out amazing, often measured in parts per million. And salmonids are probably near the best in scent detection. For thousands of years, fishermen have used bait on hooks to persuade fish to bite.
Some awesome kokanee fisherman or fisherwoman discovered a long time ago that kokanee will bite a lure baited with white shoepeg corn. And that discovery has been passed down for many years to the present time. What has not been passed down is why white shoepeg corn works so well.
It turns out that white shoepeg corn has an amino acid that is a bite stimulant for kokanee, something that yellow corn does not have. White shoepeg corn also manages to stay on the hook fairly well at kokanee trolling speeds. My research has revealed another interesting characteristic of white shoepeg corn: it stays white down the entire water column without any fade. As such, it presents a clearly defined target for the fish to attack. (For doubters, take a kernel of white shoepeg corn into a dark closet and shine a black light on it.)
Over the years, it has become popular to add additional scent to the corn by brining it first. Such scents have included anise, garlic, vanilla, and a host of others. Savvy kokanee fishermen would have more than one type of scented corn to entice the kokanee; in case the first one didn’t seem to work, they would have a backup. I know that making up different scent combinations is part of the wonderful pre-fishing ritual. Some even dye the corn different colors. More ritual.
In the past, I endorsed using two kernels of corn on each of the tandem hooks in the lure. I have changed my philosophy a bit over the years. I found out that putting corn only on the leading hook helped prevent that dreaded “short” bite. A “short” bite is where the fish targets the trailing hook, hits it, and does not get hooked. The same concept is where the fish will take a bite out of a worm that extends beyond the hook. Either way, the fish wins, and you get that wonderful, frustrated feeling.
Placing the corn on the leading hook takes advantage of a fish’s biology. Since a fish cannot see directly in front of its snout a distance of about two inches, placing the target scent corn on the leading hook will make the trailing hook invisible to the fish. The result is a higher percentage of hook-ups and deeper penetration of the hooks.
I have also studied the hydrodynamics of putting two kernels of corn on the leading and trailing hooks. At kokanee trolling speeds, using two kernels on each hook significantly dampens the action of the lure. This poses an issue. I want maximum action on my lure, and I also want to maximize the scent on my lure. Can I have both action and scent without compromising the action of the lure? And I also want to prevent the “short” bite.
The best solution finally emerges as being obvious all along. Many scents now come available with a sticky gel. In my opinion, these scents are more powerful bite stimulants than anything that corn can produce by itself. I now use only a single kernel of undyed, and otherwise unscented, white corn on the leading hook only, and place some gel on the beads of my beaded spinners. This gives maximum scent to my lure without interfering with its action. If I am using a squid or a hoochie, I place some of the gel inside the squid or hoochie body, again using but a single piece of white shoepeg corn on the leading hook. I believe my success rate has increased using this setup.
At the end of the day, do your best to rinse off the gel on your lures. Using generous amounts of hot water will help. I have now substituted my pre-fishing “brine the corn ritual” for a post-fishing “clean the lures ritual.” I have found the gel scents of anise, kokanee special, garlic, and especially bloody tuna to be excellent.
