Ever since Jesus called the fisherman Peter and his companions and later re-called them in his post-resurrection appearances, the fish has become an important Christian symbol. In particular, during the first few centuries of the Christian era when Roman persecutions broke out, the fish became a sign whereby harassed believers communicated with one another. It was not uncommon when strangers met for one of them to draw a fish in the sand thus indicating his allegiance to Christ the Lord.
