Canned food with fish as a secondary ingredient

How often do you feed foods that have fish, say, 3rd or 4th on the ingredient list? Like Friskies pates with a little fish or 4Health chicken and whitefish pate?

It would be ok to feed something like that once or twice a week. Some people may limit all foods that contain some fish / seafood to treats or the occasional meal.

I'm not that hardcore about the "no fish" thing, but I don't feed lower quality foods with fish. Sometimes I'll feed something with fish in it several times a week. For example I feed the Ziwipeak air dried Venison and Fish and the canned venison and fish, but I know Ziwipeak has high standards for their foods so I don't really worry about the fish issue. I wouldn't feed lower quality foods with fish in them very often.
