ABSTRACT
Synchronous spawning as mass reproduction is well known to occur in many hermatypic corals, which is one of the mysterious life birth events. However, its contributing mechanism has not yet been clarified. This study placed focus on elucidating a neurotransmitter as endocrine signals that contribute to the synchronous spawning. First, the determination method of the neurotransmitters in coral was established by LC/MS in the selective ion mode together with a solid phase extraction method. As a result, the similar contents of the neurotransmitters for dopamine (DA), adrenaline (AD) and noradrenaline (NR) were detected in both the hermatypic corals of Acropora intermedia and Acropora digitifera. More interestingly, these neurotransmitters increased through the reproductive event during the synchronous spawning of A. intermedia, particularly, remarkable changes in the NR and DA were observed. In addition, hydrogen peroxide is known as the spawning stimulant and the metabolic by-product of the neurotransmitters, which was exposed to A. digitifera, then the neurotransmitters increased as well as those of the synchronization of spawning. All of the results suggested that the neurotransmitters contribute to the synchronous spawning in the hermatypic corals.
