Ichthyophagi (Gr. for "fish-eaters"), the name given by ancient geographers to several coast-dwelling peoples in different parts of the world and ethnically unrelated.
Nearchus mentions such a race as inhabiting the barren shores of the Mekran on the Arabian Sea
while Pliny relates the existence of such tribes on the islands in the Persian Gulf
Herodotus (book i. c. 200) mentions three tribes of the Babylonians who were solely fish-eaters, and in book iii. c. 19 refers to Ichthyophagi in Egypt.
The existence of such tribes was confirmed by Sir Richard F Burton (El-Medinah, p. 144).
