Mainly salmon and tuna products as well as Alaska pollack fillets were imported, and in 2016 half of all imports (49%) originated from the EU. Poland was the most important single supplier of fish and fisheries products in 2016, ahead of the People’s Republic of China (hereafter “China”), and was instrumental in ensuring that the German market was supplied with adequate quantities of canned herring, deep-frozen breaded fish fillets and salmon products. In most federal states people are required to hold an angling licence if they wish to engage in independent pole-and-line fishing, which requires knowledge in the subjects of fish biology, hydrology, water management, animal welfare and water conservation.
