If we can make a robot fish which convinces real ones to form a shoal around it, then today’s invention is one such cyber creature which can support the fishing industry.
A number of robot fish would be cast overboard and swim until they had attracted a sizeable number of fellow pisceans.
Each robot fish would then locate the nets of its home fleet and swim inside.
It would then exit, by homing in on a fish flap in the net -allowing the process to be repeated.
