Results of winter flounder age-reader precision test
against randomly selected samples from the first and third quarters of the 2004 NEFSC commercial samples.
(A) Age-bias plot, showing the average age attained during the test
for fish of each production age. Error bars indicate
95% confidence intervals. (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 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
production ages. (C) Results summary, indicating results of the test
for each production age.
