Sardines are an important part of the food chain. Jupiterimages/Photos.com/Getty Images. Sardines live in large schools that may contain thousands of fish. They typically feed on plankton and are close to the bottom of the food chain; many different kinds of predators eat sardines, including humans.
Finding fresh sardines is a good reason to drop everything and call all your friends. Sardines rot faster than almost any other fish -- its all those omega-3s -- so buy a bunch and eat them the day you find them, because you never know when you'll see fresh sardines at the market again.y advice: Never freeze fresh sardines. Look for sardines that are clean-smelling and whole. Try to avoid bruised fish, and definitely avoid any fish with belly burn, a condition where the belly is broken and the guts are starting to come out.
