Does she long, or is she dreadful? She is probably just staring straight ahead like all her conspecifics, the little yellow rubber duck, on a landing in the small Saarland town of Völklingen. In her case, the view would be quite remarkable: a hall large enough for two dozen trucks, filled with eight rectangular water basins. Inside: sea bass, sea bream, yellowtail mackerel – so many that every second new fins appear on the surface of the water and then disappear again. “This is the only functioning fish farm with salt water without access to the sea in Europe,” says René Schneider, head of the Fresh Corporation and thus also the master of the gray hall on an industrial wasteland south of Völklingen.
