On the West Kamchatka continental shelf, many female king crabs, Paralithodes camtschatica (TILESIUS), which were in the period of releasing prezoea larvae were caught even in areas over 15 miles away from the coast (Fig. 2). However, zoea larvae and juveniles less than 52.4mm in carapace width were scarcely caught in this area (Fig. 4). Conclusions of this study indicate that in the area over 15 miles away from the coast, south of about 57°30N, female king crabs do not take part in the reproduction of the available stock and the effective intensity of their reproduction is none.
