Fish farms are local super polluters

Fish farms


Aquaculture is a farming method whereby fish, shellfish and molluscs are kept artificially in ponds or pools. People use closed or open cages. Almost all fish and shellfish that are eaten currently come from these artificial breeding farms. Halibut in open cages in North Europe, carp in closed systems in central Europe, catfish in closed systems in the Netherlands, eels in the Netherlands among others, trout in Italy, Scandinavia and France, sturgeon in France, Germany and Belgium, turbot a lot in Spain, tilapia in almost all countries in the world, salmon in Norway, Scotland and Chile, sea bass in Greece, Turkey and Israel, oysters in Zeeland and Brittany, lobster in the Netherlands and mussels in Zeeland and the Waddenzee.

In tropical countries a lot of prawns are farmed. In many of these countries mangrove forests have to be destroyed in order to make room for the enormous tanks. Fish farms cause enormous damage and pollute the local sea floors. The surrounding coasts and river deltas are often surrounded by enormous sea lice that come from the farms.

Farmed salmon have changed in just a few generations into fat, listless great lumps that mainly excel at getting fat. They no longer swim upstream in fast-flowing rivers. Rivers in Norway are treated/poisoned with the insecticide Rotenone in order to eliminate the parasite “gyrodactylus salaris”. Cause: salmon farms.
