Otolith samples had been accumulated within fishery separate surveys from inside the 1999–2002 off around three close coast reefs for the eastern coast out-of Tasmania, Australia: Point Bailey (PB, n = 134), Eaglehawk Shoulder (EHN, n = 132) and Hen and Poultry Rocks (HCR, n = 134 fish (Contour 1a,b). Fish was in fact cpled whenever overall length are >130 mm (look for Ewing ainsi que al., 2003 for further testing facts). The formation of yearly progress increments within the red-colored wrasse otoliths keeps been verified (Ewing ainsi que al., 2003 ), and age reliability (computed playing with mediocre commission error (APE), Beamish & Fournier, 1981 ) is actually higher (0.8% inside readers, dos.6% one of customers; Ewing et al., 2003 ).
Sex wasn’t felt due to suspicion up to whenever fish sex-changed to people and research from von Bertalanffy increases designs appearing restricted intercourse-certain variations in increases (Ewing et al
Sagittal otolith sections were viewed under 100x magnification, images taken using a Leica camera (MZ16FA) and increment measurements made using Leica Application Suite (version 4, Leica Microsystems Ltd) along an axis from the primordium to the other edge of the ventral lobe.
