Figure 5.
Boxplot of mass (mg) estimated by different methods for (a) Campula oblonga, (b) Bolbosoma capitatum and (c) Caligus elongatus. Continuous line indicates the median value for each method. Fill point represents the mean individual mass for each method. Dashed line represents the mean mass value of a single individual obtained by direct method. Method 1: clay model; Method 2: image analysis; Method 3: geometric approximation, 3a ellipsoid, 3b cylinder.
