|As you know, menhaden, locally known as "bunker" is a bait fish collected in purse seines by the millions by Omega Protein Corporation and turned into omega-3 fish oil. Further, the bunker plays an important role in our ecosystem as both a forage fish for striped bass, weakfish, bluefish, and predatory birds such as osprey and eagles as well as serving as a filter feeder because they feed on phytoplankton and zooplankton at various life stages.|
Even such entities as NOAA have claimed that omega-3 fatty acids have been shown to cut risks of heart disease and possibly other diseases, such as Alzheimer's.
New studies, however, have shown this may be a crock; for example;
“Eating baked or broiled fish once a week is good for the brain, regardless of how much omega-3 fatty acid it contains, according to researchers at the University of Pittsburgh School of Medicine.
”The findings, published online recently in the American Journal of Preventive Medicine, add to growing evidence that lifestyle factors contribute to brain health later in life….
”…study shows that people who ate a diet that included baked or broiled, but not fried, fish have larger brain volumes in regions associated with memory and cognition…. "We did not find a relationship between omega-3 levels and these brain changes….'” 
And, "A review of 20 studies covering nearly 70,000 participants finds no statistically significant evidence that supplementation with omega-3 polyunsaturated fatty acids (PUFAs), commonly referred to as fish oil supplements, is linked to a lower risk of heart attack, stroke, or premature death."
