1. A fish processing device arranged to receive a fish, said fish processing device comprising:
a transport mechanism with a surface arranged to transport the fish along a transport direction, said fish being oriented with a head end towards or opposite the transport direction and the abdominal cavity of the fish oriented opposite to the surface of the transport mechanism,
a first suction device comprising:
a first vacuum nozzle arranged to suck at least liquid and blood vessels from the fish,
a first actuator mechanism for moving the first vacuum nozzle,
at least a first jet nozzle arranged to spray a pressurized liquid into the abdominal cavity of the fish, so as to loosen blood and blood vessels along the spine of said fish,
a controller arranged to control the first actuator mechanism and the at least first jet nozzle, so as:
to cause the first jet nozzle to spray pressurized liquid along the spine of said fish,
to cause the first vacuum nozzle to enter the abdominal cavity of the fish in a first angle relative to a longitudinal axis of said fish, to move the first vacuum nozzle in a first direction relative to the transport direction, until the first vacuum nozzle reaches an end of the abdominal cavity of said fish while sucking blood and blood vessels from the abdominal cavity along the spine of said fish, and
to cause the first vacuum nozzle to be oriented towards the abdominal cavity of the fish at a second angle relative to the longitudinal axis of said fish, and to move the first vacuum nozzle in a second direction being opposite the first direction while sucking blood and blood vessels from the abdominal cavity along the spine of said fish, until reaching an opposite end of the abdominal cavity of said fish, where the first vacuum nozzle is moved to exit the abdominal cavity of said fish.
