The size and spatial distribution of the blue shark, Prionace glauca, were described
based on 5,897 specimens, that were collected by scientific observers on-board the
Taiwanese large-scale tuna longline vessels in the North Pacific between June 2004 and
December 2020. Size segregation was found, and the mean size of blue sharks in area B
(0-25°N) was significantly smaller than that in area A (north of 25°N). No significant
sex segregation was found. Males predominated in the size range of 170-280 cm and
170-200 cm TL in area A and B, respectively.
