As far as I know, fishermen are not afraid of red snapper. Red snapper is a common marine fish. Its meat is garlic petal-shaped, tough and affordable, and it is a favorite seafood ingredient for many people.

Of course, different places and people may have different cultural customs and taboos. Perhaps in some places or some fishermen's groups, there will be special taboos on certain fish or fishing behavior. But as far as red snapper is concerned, there is no clear evidence that fishermen generally avoid this kind of fish.
