abstract = {Most species of baleen whales were subject to intensive overexploitation by commercial whaling in this and previous centuries, and many populations were reduced to small fractions of their original sizes. Here, we review the status of baleen whale stocks, with an emphasis on those that are known or thought to be critically endangered. Current data suggest that, of the various threats potentially affecting baleen whales, only entanglement in fishing gear and ship strikes may be significant at the population level, and then only in those populations which are already at critically low abundance. The impact of some problems (vessel harassment, and commercial or aboriginal whaling) is at present probably minor. For others (contaminants, habitat degradation, disease), existing data either indicate no immediate cause for concern, or are insufficient to permit an assessment. While the prospect for many baleen whales appears good, there are notable exceptions: populations that are of greatest concern are those suffering from low abundance and associated problems, including (in some cases) anthropogenic mortality. These include: all Northern Right N hales Eubalaena glacialis. Bowhead Whales Balaena mysticetus of the Okhotsk Sea and various eastern Arctic populations. western Gray Whales Eschrichtius robustus, and probably many Blue Whale Balaenoptera musculus populations. We review the status of these populations and. where known, the issues potentially affecting their recovery. Although Humpback Whales Megaptera novaeangliae and Southern Right Whales Eubalaena australis were also heavily exploited by whaling. existing data indicate strong recovery in most studied populations of these species.},

abstract = {INTRODUCTION During the 1982 and 1983 field seasons on Tulip, an effort was made to assess the status of small whale fisheries in Djibouti, Oman and Sri Lanka. In lieu of the fact that the World Wildlife Funds Indian Ocean Whale study still has one more year of field work, this preliminary report will only summarise our findings as of April, 1983. Officials and fisherman were contacted during port calls in 1982 to obtain information about local hunting and entrapment of cetaceans and members of the Tulip crew travelled to 9 harbours in Sri Lanka to interview fishermen. Dolphins seen in fish markets were measured, identified, stomach contents taken, and skulls collected for positive identification. In 1982 one fisherman on the west coast of Sri Lanka was asked to keep a daily log of all cetaceans entrapped or harpooned for a duration of one year. In 1983 we increased the number of harbours Monitored and four additional fishermen, three on the east coast and one on the west coast, were asked to keep these journals. A constant watch was kept at sea for all cetacean sightings. Species seen were identified using three identification guides: Whales, Dolphins and Porpoises of the Eastern North Pacific and Adjacent Arctic Waters (Leatherwood et al., 1982), Sea Guide to, Whales of the World (Watson, 1982), and A Field Guide to Whales and Dolphins (Captain Morzer Bruyns, 1971). When the identification was questionable, animals were photographed for confirmation of identity at a later date. },
