Are sardines a white fish? How about roe?

[Guest guest]

So I'm reading about babyfood and it says when you start fish to start with

" white " fish like cod, flounder and haddock. Do sardines count as white

fish?

Does roe fall under the same guideline/does it matter if roe comes from a

red fish (like salmon)?

Anyone know the logic in sticking to white fish? I'd far rather feed

sardines and salmon roe than bottom feeding flounder.
