| Summary: | No abstracts are to be cited without prior reference to the author.Data on spiny dogfish caught by salmon driftnets in the Pacific off the Kuril Islands and Kamchatka are summarized. The highest occurrence of this shark was observed off the southeastern Kamchatkan coast and opposite the First Kuril Strait where it occurred in July–November but most frequently in October–November during northward feeding migrations. Largest specimens (over 90 cm) occurred within the upper 100-m layer only. Catches were represented by individuals of 54–121 cm total length with mean 81.79 cm. Sharks 76–90 cm long were most numerous (62.3%). Latitudinal changes of spiny dogfish length were detected. In southernmost area (44°–45°N), total length varied from 75 to 112 cm (mean 83.8 cm) while in the northernmost one (52°–53°N) it was 91–63 cm with mean 71.7 cm. Catches were represented mostly by immature individuals (97.6% of females and 83.7% of males). Maximum total length of immature females was 109 cm, whereas minimum mature ... |
