Pacific halibut

Pacific halibut is common near western Kamchatka, but is not numerous in general. It is more often met near eastern Kamchatka and western part of the Bering Sea. Pacific halibut is one of the biggest fish species. Official registers mention several specimens 239-267 cm long, weighing 230-345 kg. Such unique specimens are caught rarely, but halibuts 100-180 cm long with the weight of 50-80 kg are a usual catch, especially in the western part of the Bering Sea. Commercial catch shows predominance of 40-90-cm-long specimens with the weight of up to 6-8 kg. The maximum age of life is 35 years; the schools are dominated 5-12-year-old specimens.
Halibut reproduces in autumn and winter; in the Bering Sea – from October till November. The species lives at the depth of 10-700 meters. Seasonal migrations mean that halibut abandons depths less than 50 meters in winter seasons and concentrates at the depth of 300-500 meters. In summertime, halibut shifts towards the shelf; however, the depths of 50-100 meters serve as a habitat for small and immature specimens, while larger ones demonstrate only occasional appearance and live mainly on the continental slope.
