ルアーのリアルさを科学する

Ever wonder how your fishing lure actually compares to a real minnow? For the first time ever, we use SCIENCE to compare the motions of a swimming fish to lures. The field of science called BIOMECHANICS explains how possible it is to mimic nature. Lure designers everywhere pay attention: This video will tell you how to design a lure with the most realistic swimming movements!

now watching your bait being worked back to the boat you could think man that looks really fish oh,whaｔ that looks awesome! but how do we really know, if our lures are matching exactly how a real fish is swimming. we want to know how bait fish look,as well as move. so wouldn’t it be nice to know if the motions or swim baits match that of a real fish swimming. well there’s a field of science called biomechanics that does exactly that. it measures precisely the motions of how animals move. now scientists do this because nature’s inspirations are often far better than anything we can engineer or design ourselves. my scientific expertise is in fishes and i study how they swim. now one of the key questions for swim bait designers is how do you mimic exactly how a real fish swims and we all have swim baits in our tackle box they range from one segment to two segments to ten segments. but are more segments actually better not necessarily. fish are flexible in certain parts along their bodies but not others. how might we go about studying this. first we need to look at a real fish swimming then. perform a computer analysis of their swimming motions. treating their body as a series of segments. now starting with one segment in pink, you can see it doesn’t match the actual shape of the fish in blue. one segment will look like this, two segments would look like this, and three would look like this. now what this approach allows me to do is determine how many segments does it take to get to a real fish. the graph you see shows accuracy on the horizontal or x-axis and the number of segments of the swim bait on the vertical or y-axis. here’s our one segment swim bait and you can see that it’s only five percent accurate. two segments you get to sixty percent and three segments you can get to eighty percent five segments would get you to 90. we can finally measure and quantify the behavior of a swimming fish and a swimming swim bait. now you can go up to 10 segments and that would make it really accurate, or would it some parts of the fish aren’t that flexible so you don’t need 10 segments. now the kicker is that to mimic steady swimming which is the preferred retrieve for swim bait anglers slow and steady, five segments is pretty good. but for turning it might take fewer segments nature’s designs are so much more sophisticated than anything we humans can engineer today. so a real fish can use its body as a five segment robot or a two segment robot depending on its behavior it all boils down to how the fish is behaving. so glide baits for example they could have one or two segments and turn just fine. but if you retrieve it steadily it’s just not gonna mimic a real fish swimming for swim baits think bang for buck. think of protein ingested versus energy expended and in this case bigger isn’t always better. a swim bait might not need to act exactly like a real fish it just needs to seem like it’s swimming inefficiently or unaware. jimmy leo signing off from fish code studios until we meet again stay safe and stay curious. so if you like what you see please subscribe as scientists we’re in the lab kind of measuring things all the time but it’s really you guys as the anglers in the field that are seeing interesting fish behaviors. so if you got a tip on swimbait fishing or an observation of a cool fish behavior please leave a comment below.
