Benthic-pelagic coupling are processes that connect the benthic zone and the pelagic zone through the exchange of energy, mass, or nutrients. These processes play a prominent role in both freshwater and marine ecosystems and are influenced by a number of chemical, biological, and physical forces that are crucial to functions from nutrient cycling to energy transfer in food webs.
The feeds, in the form of granules or pellets, give nutrition in a stable and concentrated form, enabling the fish to feed efficiently and grow to their full potential. Many of the fish farmed more intensively around the world today are carnivorous, such as Atlantic salmon , trout , sea bass, and turbot .
