Many species of fish lived in the Sea of Galilee and the Jordan. They were sometimes caught with a hook (Matt. 17: 27) but more often by letting a net into the water in a semicircle and gradually drawing it ashore (Matt. 13: 47–50). There was an industry of fish‐curing at Taricheae. Pickled fish were sent up to Jerusalem.
Early Christians used a fish as a cryptogram or symbol for Christ, especially in the Eucharist on account of the fish mentioned at the Feeding of the Multitude (Mark 6: 38). Moreover, additionally, the initial letters in Greek of Jesus Christ, Son of God, Saviour, spelt out the word ichthus (fish).
