Relationship between swimbladder internal tube length and body size in male Ophidion rochei. There was a high correlation (r2 = 0.83 (N = 68), p < 0.0001) between the internal tube length and the total length of the fish. Black dots: observations for the 68 males Ophidion rochei from Costa Brava. Grey line: regression line (y = 0.1944x – 31.14) calculated for the 68 male swimbladders.
