In 2020, Baden-Württemberg's aquaculture farms saw a 7.5% decrease in fish production, totaling 2.7 million kilograms, due to fish diseases, particularly affecting rainbow trout. Despite this decline, the demand for Alsatian char has increased, making it the second most produced fish after rainbow trout. There were 105 aquaculture farms in the region, with most using flow systems and marketing through wholesalers. Direct sales to consumers were 14% of the total.
