In the current technology, fish feed extruders play a key role in production lines. Although the majority of the process of the fish feed production occurs in the extruder, grinding and mixing can highly affect the quality of the final product. [14] Water is added and the resulting paste is extruded through holes in a metal plate. The diameter ...
The feeding habits of a juvenile animal, and, as a consequence, its trophic level, can change as it grows up. The fisheries scientist Daniel Pauly sets the values of trophic levels to one in primary producers and detritus , two in herbivores and detritivores (primary consumers), three in secondary consumers, and so on.
