In summary, it’s possible to replace at least some of a marine fish’s diet with high quality, specifically selected vegetable oils, but it’s not a perfect replacement in every way.

For example, growth seems unaffected, but flavor, odor and other important factors are affected.

Some, but not all, affected factors can be reformed by a “finishing diet” consisting of normal food containing fish oil.
