Effects of ethanol preservation on otolith microchemistry
Abstract:Solution‐based inductively coupled plasma‐mass spectrometry was used to examine the effects of exposure time to ethanol (0, 1, 3, 9, 27 and 81 days) and ethanol quality (ACS‐v. HPLC‐grade) on strontium (Sr) and barium (Ba) concentrations in sagittal otoliths of hatchery‐raised and wild‐caught young‐of‐the‐year walleye Stizostedion vitreum. No effect of either attribute on Sr and Ba concentrations were detected, indicating that metabolically inert elements that replace calcium in the calcium carbonate matrix (e.g. Sr and Ba) are not influenced by storage in 95% ethanol.
