Abstract: Serotonin (5-HT) and dopamine (DA) as neurotransmitters are important for many physiological functions by combining with different types of receptors. Both of them are widely distributed in different tissues of many animals, which play important role in agonistic behavior. There are five major 5-HT receptors (including 5-HT1A, 5-HT1B, 5HT2A, 5HT2B and 5-HT7) and four receptors of dopamine (DA1A, DA1B, DA2 and DA4) in crustaceans. The distributions of 5-HT, DA and their receptors are species and tissuespecific. In addition, 5-HT and DA participate in the regulation of agonistic behavior of decapods crustaceans by different regulation mechanisms. 5-HT can regulate the release of cyclic adenosine monophosphate (cAMP) or hyperglycemic hormone (CHH), which can promote or inhibit the agonistic behavior in crustaceans. In contrast, dopamine could affect the agonistic behavior by mediating the release of cAMP and COMT.
