Bream are a very common and widespread species of fish found in most rivers in Central and Northern Europe. It has a down-turned, protractile mouth making it ideally suited to bottom feeding. Young Bream can superficially look like other similar silver fish like Roach and Dace, but from their side profile they appear to have more of a diamond shape compared to most other freshwater fish species. As they mature they adopt a more bronze colour and grow deeper to appear more disk shaped.
As omnivorous bottom feeders, bream will eat a wide variety of food found in the mud and silt in the riverbed. They ’dig’ into the substrate to pick out any morsels like Mosquito Larvae, Caddisfly Larvae and Freshwater Shrimp, as well as plant-based food like pondweed and fallen berries. When larger food is in short supply they are able to and filter fine sediment through their gill rakers to pick out microscopic prey. Young bream are numerous and slower than similar silver fish so they are easy prey for birds like Heron and Cormorant. Because of the shape and size of mature fish they become less edible for birds, but are a more appealing and substantial meal for mammals like Otters.
