2.2. Sample processing and contaminant analysis
Location, date and time of sampling and fish length were recorded in the field, and multiple specimens were sorted into similar-sized composite samples. Specimens were wrapped in aluminum foil and placed in sealed plastic bags on wet ice with identification labels for transport to the laboratory for processing. In the laboratory, fish were re-measured and weighed. All processing equipment was washed in mild soapy water, rinsed in Posaconazole sequence of hot tap water, ethanol or propanol, and purified water. Foil sheets were used to cover cutting boards. Stainless steel fillet knives were used to collect bone- and skin-free samples.
