In addition, a permanent artel (hunting

camp) was established in 1812 on the Farallon Islands for hunting fur seals and sea lions, and harvesting sea gull feathers, meat, and eggs. The southward expansion of the RAC into northern California took a tremendous toll on the area’s marine fauna. For example, Ogden (1933:36) cited the voyage of the American ship, the Albatross, from which Russian and Native Alaskan workers harvested more than 30,000 fur seals from the Farallon Islands in 1810–11, in addition to the PLX4032 manufacturer sea otter yields listed in Table 1. RAC documents noted that thousands of fur seal pelts were harvested in California waters after the founding of the Ross Colony, including 3276 from Bodega Bay alone in 1823 ( Ogden, 1933:42). Khlebnikov (1976:123) detailed the wholesale slaughter that took place on the Farallon artel where during the first six years an average of 1200–1500 fur seals were killed (for a total of 8427), which gradually decreased in number selleck chemicals llc until only 200–300 were obtained per year. About 200 sea lions were taken each year for their hides, meats, and intestines used for manufacturing baidarkas, waterproof garments, and for food. Anywhere from 5000 to 10,000 sea gulls were dispatched in a typical year, although in 1828 more than 50,000 were killed, primarily for their feathers and meat ( Khlebnikov,

1976:123). RAC documents showed that the joint contract hunting system with American merchants yielded more than 24,000 sea otter pelts from 1803 to 1812 (Table 1). Independent Russian expeditions from 1808 to 1823 harvested, at a minimum, another 6300 sea otter pelts, the majority from northern California waters (i.e., Trinidad Bay to Drake’s Bay) (Table 2). These numbers include only those sea otters hunted by the RAC and their partners. They do not include the thousands of otters obtained as part of the Spanish commercial trade that began in 1786, as well as by independent American skippers and companies (Ogden, 1941:15–44,

66–94, Appendix 1). Market hunting had a devastating outcome for local sea otter populations. Mephenoxalone It did not help matters that both yearlings and pups were harvested in large numbers (see Table 1 and Table 2). As early as 1817–1818, RAC records indicated that sea otters had been purged from the waters immediately north and south of the Ross Colony (Gibson, 1976:16; Tikhmenev, 1978:135). While the RAC continued sea otter hunting in the 1820s and 1830s, it was undertaken in partnership with the newly formed Mexican government (1823), in which the harvests were split equally between the RAC and Mexican agents. Furthermore, these hunts took place some distance from the Ross Colony using Russian ships to transport hunters from San Francisco Bay southward to southern Alta California and Baja California waters (Khlebnikov, 1976:110–113; Ogden, 1933:46–51). By all accounts sea otters had been extirpated from northern Alta California waters (Trinidad Bay to the Marin Headlands) by 1820.
