When nausea makes you cut fat, it is easy to cut the good fat too. Omega-3 fatty acids (EPA, DHA, ALA) are the exception to the low-fat rule: fish, sardines, mackerel, flaxseed, chia and walnuts deliver anti-inflammatory fat that is worth fitting in — typically in modest, well-tolerated portions. This list ranks foods by omega-3 content (ALA + EPA + DHA per 100 g).

Yes — salmon, sardines and mackerel are protein-rich and well tolerated by most people in normal portions. They are actually a smart choice: protein plus omega-3 in one food, without the heaviness of fried or fatty dishes.
Dietary guidelines generally suggest two servings of fatty fish per week (the AHA recommendation), which covers EPA and DHA needs. Plant sources like flaxseed and chia provide ALA. Supplements are a separate question to discuss with a healthcare provider.
Fatty fish in a normal serving size is usually fine; the nausea risk comes from heavy frying and large portions, not from the fish itself. If you are mid dose-increase, keep the portion modest and skip any heavy sauce.
