Results of haddock age-reader accuracy test
against randomly selected samples from the NEFSC reference collection,
conducted after production ageing.
(A) Age-bias plot, showing the average age attained during the test
for fish of each age from the reference collection. Error bars indicate
95% confidence intervals. (B) Age-frequency table, showing the test ages
across the top and the reference ages on the
left. Numbers in the shaded boxes indicate agreement between the two
ages. Numbers above this diagonal indicate fish which were over-aged during
the test; those below the shaded boxes were under-aged. Total age frequencies
are given by age for both the test and reference ages. (C) Results summary,
indicating results of the test for each reference age.
