s in the Sea of Okhotsk. In 1854 alone some 160 whaleships visited the region; the following year more than 130 ships. The next year, 1856, nearly 150 ships sailed to the Okhotsk. By 1857, the number of ships had declined to a little over 100. With declining catches from 1858 to 1860 the fleet shifted its focus back to the Bering Strait region. Many of the ships converged on the Shantar Islands, anchoring within the archipelago's many sheltered bays. On July 28, 1854 the New Bedford ship Isabella reported ninety-four ships in sight from her deck. A few days later the Lexington, of Nantucket, reported one hundred whaleboats were about chasing whales. Ships continued to hunt whales in the Sea of Okhotsk until the early 20th century.
Oil reserves
Twenty-nine zones of possible oil and gas accumulation have been identified on the Sea of Okhotsk shelf which runs along the coast. Total reserves are estimated at 3.5 billion tons of equivalent fuel, including 1.2 billion tons of oil and 1.5 billion cubic meters of gas.Notable seaports
