“…Video tracking allows observation and analysis of the motion of larvae and thus insight into their pre-settlement behavior (Lagersson and Høeg 2002, Marechal, Hellio et al 2004, Prendergast, Zurn et al 2008, Aldred, Li et al 2010. Stereoscopic tracking adds the missing third dimension, required for calculation of parameters such as velocity and directedness, and enables a detailed analysis of cyprid distributions and swimming parameters as function of coating properties (Maleschlijski, Bauer et al 2014, Maleschlijski, Bauer et al 2015. Further, the surface exploratory behavior in direct contact with the substratum differs when different surface chemistries are applied .…”
