Asteroids rely on chemosensation of semiochemicals (chemical signals) throughout their life-history to modulate behaviours including foraging, spawning, settlement, metamorphosis, defence, dispersal and predator avoidance (Motti et al. 2018). Research has confirmed chemosensation is pivotal to many of these behaviours in CoTS, and semiochemicals have the potential to modify CoTS behaviour and regulate CoTS populations. Despite this knowledge, application of semiochemicals to reduce the occurrence of population outbreaks has to-date been unrealised (Høj et al. 2020). While the nature of these semiochemicals is under investigation, their implementation, which requires release strategies and devices have proven efficacy towards CoTS and are effective, environmentally safe, deployable at reef scale and economical, has not yet been considered. Addressing this is critical to the development of innovative control technologies to enhance the CoTS Integrated Pest Management program. Here, we apply the Relocatable Coastal Ocean Model to develop hydrodynamic models to understand the spatial and temporal footprint of semiochemical delivery around reefs. Using this information, existing delivery strategies and devices employed to control other pest species in the aquatic environment are reviewed and their applicability to semiochemical-based control of CoTS considered. Recommendations are offered to support the discovery of semiochemicals and design of new release technologies.
