Figure 2. Illustration of cutting lines for Atlantic halibut. The fish were cut along the red, dotted line to give a sample including the head of the fish and two different sections of the fillet behind the head, the more lean part of the fillet (B-cut) and the more oily part of the fillet (I-cut). In some cases, the head was not included in the sample, but was cut off along the black dotted line. The sample was frozen before delivery to HI.
