Even speaking of freshwater fish in general, they are undoubtedly among the fastest growers.
The type II taste bud cells make up about another third of the cells in the taste bud and express G-protein coupled receptors that are associated with chemoreception. They usually express either type 1 or type 2 taste receptors, but one cell might detect different stimuli, such as umami and sweetness. [5]
