Here are three air extractors for fishing floats. Compared to commercially available products, the cost performance is significantly better. ◎ Comes with a string to prevent loss. ◎ Also includes a stainless steel rod for cleaning the needle hole. Without this, it clogs quickly. Even if you blow air into it, the blockage is difficult to clear. ◎ Needle length: approximately 30mm, needle tip inner diameter: 0.9mm, needle tip outer diameter: 1.2mm. (Air won't escape with a thinner needle. A thicker needle will damage small fish. This is the optimal thickness for small fish.) ★ For small filefish and female fish during spawning season, release them after air extraction. If you don't extract the air, they can't dive on their own and become food for kites. Small scorpionfish are the same. ★ On boats equipped with circulating seawater tanks, fish that have had air extracted swim vigorously and in good condition until the end of the trip. Watching filefish swimming energetically is enjoyable. If you keep them alive for a long time, you become attached to them, and you often release them at the end of the trip ^_^. ◎ See the photos for how to extract air. Insert the needle about 5mm, and the air will hiss out. It's easier to extract air if you gently press on the inflated part of the swim bladder while inserting the needle. Be careful not to press too hard, or the internal organs will come out of the anus. Remove about half the air; removing all of it is apparently not good. Air is said to re-accumulate in the swim bladders of released fish. ★ 【Caution】 Sharpen the needle tip with a file or similar tool from time to time. If the needle tip becomes dull, it won't penetrate the soft, elastic swim bladder even if it pierces the skin. #FishingTackle #AirExtractor #AirRelease #Needle #SwimBladderAirExtractor #SwimBladderAirRelease
