Spawning behaviour and chemical communication of tropical donkey's-ear abalone (haliotis asinina linnaeus 1758)

Abstract

This study aims to reveal spawning behaviors and chemical communication of the tropical donkey's ear abalone, Haliotis asinina Linnaeus 1758. H. asinina is a broadcast spawner, they would aggregate before the mass-spawning. Chemical communication plays an important role in the spawning of this mollusc. Results showed that sexually matured females H. asinina were strongly attracted to the matured males abalone.
