blowfish, globefish, tetraodon
鮐 centers on a type of fish: specifically blowfish, globefish, or tetraodon. These are all names for the same puffer-like fish.
鮐 combines 魚 (fish) with 台, which likely contributes the sound. The character is used for blowfish and related species.
The left side is a fish 魚, and the right side 台 looks like a platform. Imagine a blowfish puffing up on a platform, ready to be identified as a globefish.
For タイ, picture a blowfish wearing a tie: tie -> タイ, and the fish looks dapper on its platform.
