00:00why do crab farmers pour larvae onto a wooden board instead of directly into the water
00:04looks like wasting time actually it's saving the stock
00:06the real risk isn't in the water it's in that one second of entry
00:10sudden temperature change different dissolved oxygen levels density shock if the entire bag
00:14gets dumped directly into the pond weak larvae gets shocked into losing balance flipping over
00:18sinking to the bottom all the damage happens in that one moment so he doesn't the wooden board
00:23is a buffer zone crab larvae crawl around on the board first moving and slowly adapting to the
00:27environment strong ones naturally rush toward the water themselves slow ones get exposed immediately
00:32first round of selection happens right on the board still not done some farmers slowly push the board
00:37along the water surface letting larvae spread out gradually as they move no forcing no crowding
00:42each other one wooden board completes buffering screening and distribution in three steps
00:47people who truly understand rush farming don't just throw larvae in they eliminate the risk before
00:51anything enters the water
