    Most fish die the same way — slow suffocation in the open air. It’s easy for fishers, but it causes fish tons of stress, and floods their bodies with chemicals like cortisol, adrenaline, and lactic acid. Those chemicals make the fish taste bad, smell “fishy,” and rot quickly. 

    But there's a better way: a four-step Japanese method called ikejime. It involves sharp knives. And a brain spike. 

    We adapted this video from Vox’s Future Perfect podcast, which goes much more in depth on ikejime:

                I don't blame commercial fishers to allow fish to suffocate, I mean it isn't like they can catch a hundred fish and then individually spike their brains and spinal chord.

                                                    Actually sometimes it doesn't, they fall on the floor and roll and get injured on the stairs therefore the accident happened on the floor but the real accident occurred on the stairs
