Abstract
A rheotactic shrimp harvester wherein an inclined ramp having a slot extends between adjacent water tanks and water is caused to flow down the ramp from one tank to another. The shrimp reacting to the current of water flowing down the ramp move upstream on the ramp; the smaller shrimp pass through the slot in the ramp and return to the original tank while the larger shrimp go over the slot and into the next tank.
