"Omega Protein", a sign for which can be seen in the last photo, is the world's largest producer of Omega-3 Fish Oil AND North America's largest manufacture of "Fishmeal" and "Organic Fish Solubles". According to their web site their products are used in nutritional supplements for animals, humans and plants all thanks to the little Menhaden fish.
It's one of those Catch 22 propositions as this type of commercial fishing obviously depletes the population of Menhaden but the Omega Protein PR people would say that we (and our animals, both agricultural and house pets) may live longer healthier lives because of their products and also that their natural organic fertilizer (made from Menhaden) might make our food safer and healthier.
Who knows for sure????????????????
