How to conduct a rested harvest

Rested harvesting can be applied to all types of operations. One system, commonly used in sea cages, pond or raceway operations employs a sedation bag with an internal net divider to separate the bag into three zones. In this way a continual flow operation is achieved with fish continually moving through the sedation bag having been exposed to AQUI‑S^® for the necessary time to achieve the desired sedation level. If fish are in a land-based tank, the water volume can be gradually drained to a suitable level before sedating fish with AQUI‑S^®.

Continual Flow System 

The most effective method to achieve a continual flow of fish to the handling table is to divide the treatment tarpaulin into 3 zones using a net. Fish remain in zone 1 for approximately five minutes. Then the net lining between zone 1 and 2 is lowered to allow fish to be moved to zone 2. The net lining between zone 1 and 2 is then raised and the gusset opening lowered to allow entry of more fish to zone 1. After 5 minutes continue the cycle of introducing new fish every 5 minutes while continually removing fish from zone 3.
