Abstract
In isolated scale melanophores ofLabeo rohita the melanosome aggregating effect of K+ was inhibited in Ca2+ deprived medium. Moreover, the Ca2+-antagonists, verapamil and lanthanum inhibited the action of K+ in concentration dependent manner. The elevation of extracellular Ca2+ could compromise the verapamil induced inhibition in a concentration dependent manner. The cation Ca2+ appeared to be required only for K+ -induced aggregation and not melanosome aggregationper se, as in this fish adrenaline and melanin concentrating hormone effectively caused aggregation of melanosomes in Ca2+ free medium
