Figure 3: Chemical analysis conducted on cod muscle, liver and gill from the control, (nylon nets with Flexgard™ paint) and the treatment (copper Seawire pens). Unpaired t-tests, with Welch corrections, were used to compare the two, and there was no significant difference (P > 0.05) in ppm copper between fish from the 2 cage types in muscle (P = 0.68), gills (P = 0.47) or livers (P = 0.52).
