무늬오징어가 에기를 잡았다가 놓는 이유, 과학적으로 밝혀졌습니다

I felt a heavy pull and set the hook, but it was a missed strike. That wasn't because the hook was set too late. The spotted squid was "testing the waters" after grabbing the jig. There is a saying in the fishing world that "spotted squids can spot an jig even 30 meters away." However, when I looked up research papers, that 30 meters figure was calculated, not measured. There is also a study that recalculated the distance by incorporating actual seawater attenuation, but it comes with conditions (different forms of the same species, depth of 40–50m, and spawning reefs rather than jigs). So, what you can take away from that isn't the "number of meters," but simply the direction: if the water is murky, they have to come that close to spot it. Then, if they don't decide everything by eye, what do they use to determine it? The answer was the suckers. If an octopus's suckers are like "taste-testing hands," a squid's suckers are closer to a "tongue." They check the lure after catching it, and then release it based on that confirmation. Those few seconds we called a "weak bite" were actually a time for the spotted squid to keep tasting the lure. And no matter how well you make an Egi, it won't taste like actual bait. Once the squid finishes its inspection, the answer is always the same: "This is not bait." So, what we can do is not try to make the Egi taste good, but to snatch it before that judgment is made. ⚠️ The experiment discussed in this video was not conducted directly with adult spotted squid. The research conducted on spotted squid larvae and squid of the same family is factual, and I have attached the conditions exactly as they are on the screen to avoid claiming something that doesn't exist. 00:00 Opening — Why couldn't I set the hook when I caught one? 01:00 Dragging or Floating (The point where the field diverges) 01:30 "30 meters" wasn't measured, it was calculated 02:40 If water gets in, the jig doesn't look like a jig 03:14 Octopus Sucker = The tasting hand 03:34 Squid Sucker = The tongue 04:05 Jelly Experiment — The bitter taste wasn't the bait, it was a mark 04:24 Pass or Fail 05:39 That time we used to call a "bite" 06:24 Baby Striped Mackerel Experiment — The seawater is the baseline 07:04 Today's Twist — It's biting with its tongue 07:54 Then what should I put on the jig? 08:36 Trivia for New Fishing Tips (Tentacle Speed ​​· Tagged Release Distance) 09:14 Three-Line Summary 📚 Sources · Kang et al. 2023, Nature 616:378 (Squid sucker chemorecepts) · van Giesen et al. 2020, Cell 183(3):594 (Octopus sucker chemorecepts) · Kiguchi · Iida · Akiyama 2019, Fisheries & Aquaculture 67(3):225 (Striped squid larva suckers) · Ueda Yukio · Shiro Taihiko 1990, Fisheries & Aquaculture 38(3):221 (Tagged Release) #StripedSquid #Eging #StripedSquidBite
