Webanistic understanding of how vaterite affects hearing. Lychakov and Rebane 17 developed a model for predicting the effect of otolith mass-asymmetry on fish hearing. Based on the physics of otolith movement, it can be eas-ily adapted to model sensitivity differences between vateritic and aragonitic otoliths. Models can also predict Webfish has broad significance to aquaculture and conservation. As >50% of farmed fish have ∼50% loss in hearing sensitivity due to vaterite (Reimer et al., 2016), pinpointing the cause of this deformity could drive measures to improve the welfare of billions of farmed fish worldwide.
