Results of butterfish precision test using randomly selected samples from the 2006 NEFSC autumn survey. (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.
