|Results of haddock age-reader precision test
against randomly selected Gulf of Maine samples from the second quarter of the 2003 NEFSC commercial samples.
(A) Agreement plot, showing both the production and test ages. A small amount of noise was added to the data to improve visibility of overlapping data points.
(B) Age-frequency table, showing the test ages across the top and the production ages on the
left. Numbers in the shaded boxes indicate agreement between the two
ages. Numbers above this diagonal indicate fish which were under-aged during the test; those below the shaded boxes were over-aged. Total age
frequencies are given by age for both the test and
production ages. (C) Results summary, indicating results of the test
for each production age.
