WebFish samples were washed with distilled water, dried, and homogenized before analysis. All samples were dried at 508C and stored wrapped in aluminum foil. Samples were analyzed at the University of Waterloo En-vironmental Isotope Lab on an isochrom continuous flow stable isotope mass spectrometer (Micromass) coupled to a WebMar 4, 2024 · For stable isotope analysis, a total of 241 individuals from 9 species were sampled (Supplementary Table 2). All individuals were frozen (−20°C) immediately after sampling. In the laboratory, samples were defrosted, and in fish, a small piece of dorsal-anterior muscle was dissected, and skin and bones removed.

WebDec 15, 2015 · Background Fish fin is a widely used, non-lethal sample material in studies using stable isotopes to assess the ecology of fishes. However, fish fin is composed of two distinct tissues (ray and membrane) which may have different stable isotope values and are not homogeneously distributed within a fin. As such, estimates of the stable isotope … WebSep 20, 2024 · SLU Stable Isotope Laboratory. Last changed: 20 September 2024. Provides analyses for stable isotopes of several light elements.

WebJun 6, 2005 · Stable isotope analysis can provide a useful tool for determining time-integrated measures of proportional food source contributions to fish diets. Ratios of stable (non-radioactive) isotopes of common elements (e.g., C,N,S) vary among food sources, and tissues of consumers (e.g., fish) reflect the isotopic ratios of their diet. For isotopic … WebThe stable isotope profiles were significantly different among years in 2 of 5 indicator species, but the relative differences were small, and patterns were not consistent among taxa analyzed.
