Mussels - gkazan/ZAWA GitHub Wiki
Mussels are an item used to feed animals. They are obtained with the Seine Net. Currently, they cannot be cooked or eaten by the player.
When fed to an animal, mussels use the default food value, with one hunger point (1/2 shank) and 0.5 saturation.
Shellfish specialist and omnivore animals can eat mussels.
