European researchers have created a new breed of European catfish, named after the SilGen project, which is expected to replace expensive fish like salmon, tuna, and cod. The new breed is not only tasty and healthy but also adaptable, quick-growing, and disease-resistant. The SilGen project has developed a system for mass producing high-quality freshwater catfish. The researchers have bred this new breed by isolating genes responsible for beneficial traits and plan to make it more affordable through partnerships with farmers and restaurants. The catfish is expected to provide essential nutrients and give reservoirs a 'rest' as a sustainable alternative to overfished seas, rivers, and oceans.
