The evening was falling over the dark rocks of the north when the shoreline fishermen approached. A thick fishing line wound around a piece of cork, with a sizable hook, was the system used to try to catch moray eels and conger eels—sea predators that, in those years of scarcity, served to make fish soup.
To increase the chances of catching something, besides casting the baited hook in a suitable place and tying the line firmly to the ground, they also poured into the sea a liquid filled with blood and fish remains. Species that live by preying on others have keen senses to detect where there may be potential food—such as a wounded prey.
