Today's Green Tip: Farmed Fish - Better or for Worse?
However, large scale fish farms plunder huge amounts of wild fish for meal feed (about 30 lbs to produce a 6 lb. farmed salmon), which also denies seals and sea birds their natural food source.
Also, fish kept in high-density pens are vulnerable to disease, so they are pumped with high levels of antibiotics, which can seep into the natural landscape and enter the food chain, compromising the natural immunities of the wild populations.
How do we change?
Buy organic! Look for fish from low-density organic farms that respect the local ecoystem.
