Nothing is ever so simple.
For Tantric practice, fish was one of the ritual items to consume. It was forbidden, hence the lack of references to fish eating.
Also, the ancient Greeks considered fish to be a delicacy, as would be expected considering the wonderful fish available in the Mediterranean.
As for Homer, this may provide a possible explanation:

Keeping to this particular point, it is worth noting that cognate names for fishes are almost lacking in the Indo-Germanic languages. It seems that "it is only after their separation that the Indo-Germanic peoples seem to have turned their attention to fishing, and to have acquired a taste for fish as food. In the hymns of the Rigveda, fishing is still wholly unknown (cf. Zimmer, Altindisches Lehen, p. 26) ; and so, too, in the Homeric period it is only in times of extremity that fish is used by the heroes as food (Od. xii. 330 ; iv. 368)" (Prehistoric antiquities of the Aryan peoples, p. 118) So fish seems to have been unknown as food in the primeval Indo-European period. "As a rule fishing appears in close conjunction with the beginnings of navigation, indeed often is the starting-point of it. It must, therefore, be once more insisted upon that in the vocabulary of the original Indo-European language there is neither a collective term for the general notion of fish, nor an individual name for any particular kind of fish." (ibid., p. 354)

In fact, it would seem they stuck mostly to eels (The history of the Anglo-Saxons from the earliest period to the Norman Conquest, Volume 2 , p. 198).
