MSD Animal Health, a division of US-based Merck & Co, has signed a definitive agreement to acquire Norwegian fish health company Scan Aqua -- the operational affiliate of Scanvacc.

Specific terms of the agreement were not disclosed.

The acquisition of Scan Aqua includes its Rx product portfolio with the key products AQUI-S and Finquel.

AQUI-S is a sedative used during treatment, pumping, transportation, and handling of salmon and rainbow trout.

Finquel is a widely-used anesthetic mainly used in fish farming during the vaccination process and any handling events that require the fish to be fully anesthetized, such as lice counting.
