Sardines are a great choice for Omega 3! Because they are small, they do not accumulate many toxins including mercury, PCB's and lead; this incorporates, also, the Pink salmon and Chinook salmon, herring, and Hoki, which could be higher in Omega 3. You should not only consider the Omega 3 in fish but if the fish contains toxins.
