Fish oil does not reduce the risk of heart disease.

I thought it did for a long time, but I have now put away my fish-oil supplements. Not only do they not reduce the risk of heart disease, they are likely contaminated with various toxins (DDT, dioxin, PCBs, mercury, etc.) because humans have been using the oceans as a dumping ground for more than a century. There are serious warnings to reduce the frequency with which you eat tuna, for example.

From an article by Gina Kolata in the NY Times:

At one point, the notion that fish fats prevented heart trouble did seem logical. People whose diets contain a lot of fatty fish seem to have a lower incidence of heart disease. Fatty fish contains omega-3 fatty acids. Omega-3 supplements lower levels of triglycerides, and high levels of triglycerides are linked to an increased risk of heart disease. Not to mention that omega-3 fatty acids seem to reduce inflammation, a key feature of heart attacks.

But in a trial involving 12,500 people at risk for heart trouble, daily omega-3 supplements did not protect against heart disease.

Live and learn and—most especially—don’t deny reality as you learn it.

I now grind up 2 tablespoons of flaxseed (high in omega-3) every morning and have that with my breakfast.
