P-values (statistically significant in bold) for within group Chi-squared tests for uniform distribution of individual numbers of dash sequences, and Spearman correlation of the number of dash sequences and number of captures. Results are shown for the 2, 3 or 4 groups estimated to occur in 2018 and 2019. N refers to the number of individual marlin in each subgroup. For subgroups with sufficiently large sample size (n ≥ 9), there is good evidence that the number of dash sequences is not uniformly distributed and that the number of dash sequences correlates with the number of captures.
