Data Processing\/<\/strong> Reduction Methodology<\/strong><\/td>Stable isotope analysis (SIA) was conducted for all size classes of juvenile Weakfish. Weakfish muscle and liver tissues were both analyzed for stable isotopes due to the differential between turnover times. Stable isotope \u03b4 values were calculated using the formula: \u03b4HX [(Rsample\/Rstandard \u2013 1)]*1000. The superscript H is the heavy isotope of the element X and R is the ratio of heavy to light isotope (e.g., 13C\/12C) of the sample and the standard, respectively. All samples processed for SIA were dried to a constant weight in an oven for 48 hours at 60\u00b0C and ground to a fine powder using a mortar and pestle.<\/td><\/tr>
