Downgrading of catch quality due to gear influence
and operation, fish pumping and
gear hauling, cutting and
bleeding, gutting and further
on-board processing including
storage are central challenges
within catch handling. Effective
catch handling systems on board
including transfer from fishing
gear to vessel, live fish
handling and slaughtering
(stunning and bleeding) will be
focused. Furthermore, automation
of processes to obtain effective
flexible processing, increased
product quality and HSE for the
fishermen is a central topic
within this area.
The ultimate goal is to bring the fish on board alive
and keep it alive until bled and
gutted. However, a prerequisite
for more alive fish on board are
gentle and efficient capture and
first handling. Stunning of
alive catch will allow more
rapid bleeding, gutting and
rinsing of the fish. Electrical
stunning has been identified as
a fast and efficient method to
render fish unconscious and
insensible.
SINTEF Fisheries and Aquaculture are involved in
several projects focusing on
developing novel on board catch
handling systems safeguarding
the initial fish quality as well
as the fishermen’s HSE. Results
from these projects will be
presented. |
