Geographic distribution of samples of <i>P. kamoharai</i>, with the network of haplotypes analyzed and compiled from the sequences of the mitochondrial DNA control region.

<p>Intermediate points in the network of haplotypes represent hypothetical haplotypes not sampled. All haplotypes differ by only a single mutation in the network, and the sizes of the circles are proportional to their frequencies.</p

Differentiation (<i>F</i>_ST) between pairs of sampled regions in the Atlantic and Indian Oceans.

<p>Un-weighted (dashed line) and weighted (continuous line) models for the Eastern (top panel) and Western (bottom panel) Atlantic bluefin tuna.</p

Comparison of quantile regression median and least squares of weight at size.

<p>Quantile median non-linear fit (continuous line) and least squares weighted non-linear fit (line with circles) by Eastern (top panel) and Western (bottom panel) bluefin tuna stocks. Outer lines represent the 25%, 75% (thin lines) and the 2.5% and 97.5% (dashed lines) of the quantile regression estimated percentiles.</p

Estimated coefficients alpha and beta for the monthly weight-length relationship for Atlantic bluefin tuna (RWT_stdM=alpha× SFL_std(betalsMonth)).

<p>All functions correspond to straight fork length (SFL) in centimeters and round weight (RWT) in kilograms.</p

Present study results for the weight-length (RWT-SFL) relationship by stock compared with equations currently used for bluefin tuna.

<p>West = West Atlantic, East = East Atlantic, including the Mediterranean.</p
