Figure 18 . Scatterplots showing the level of agreement (linear model fit and Pearson correlation coefficient with p-value) between two subsamples of 30 fish assessed using the standardised manual method. The subsamples were generated by selecting fish 1-30 (Subsample 1) and 31-60 (Subsample 2) from the full sample of 60 (large scale trial) or 100 (small scale trial) fish.
