“…The 2 types of S. pleuronectis observed in the present study have been reported, in the same microhabitats, in other cetaceans from the Western Mediterranean (Aznar et al 1994, Agustí et al 2000a. Following a seminal paper by Skrjabin (1972), several authors (Aznar et al 1994, Agustí et al 2000a Skrjabin 1972, Aznar et al 1994, McAlpine et al 1997, Agustí et al 2000a. In Risso's dolphin, the only previous report is that of Stossich (1898) in the rectum of 1 individual.…”

“…Investigation of strandings may also be an effective means of monitoring measures implemented to reduce threats to species (e.g., to monitor changes in the incidence of vessel strikes in areas after shipping lanes have been moved). Samples from strandings also provide valuable information on anatomy and taxonomy, as well as on parasites, dietary habits, toxicology, and reproduction (Hooker et al 1997;McAlpine et al 1997; Norman et al 2004).Although some significant individual stranding events in the Maritimes have been recorded in the literature (Piers 1923;Mitchell and Kozicki 1975;McAlpine 1985;McAlpine et al 1997;Lawson and Eddington 1998;McAlpine and Rae 1999), little comprehensive information on cetacean strandings in the region has been published. Hooker et al (1997) provided a summary of the cetacean strandings in Nova Scotia covering the period , and Lucas and Hooker (2000 reviewed stranding events on Sable Island, Nova Scotia, for around the same period.…”

inclusive) from across the region. During this period, a total of 640 stranding events involving 19 species and 881individuals of both sexes and varying age groups were reported. Stranding events primarily involved single animals, although several mass strandings were recorded, the largest involving 60 Long-finned Pilot Whales (Globicephala melas). The number of strandings was found to vary substantially over time and among the three provinces. In part, this is likely a reflection of differences in local network effort among regions. Most animals were found dead ashore. Entanglement in fishing gear occurred in over 10% of the incidents. Relatively more mysticetes were found dead ashore or at sea and entangled in fishing gear than expected by chance, while more odontocetes were found stranded alive than expected. Harbour Porpoises (Phocoena phocoena) appear to be especially vulnerable to entanglement in fishing gear. Necropsies, performed on a subsample of the stranded animals, suggest that Harbour Porpoises die significantly more often from disease than mishap, while Long-finned Pilot Whales and Atlantic White-sided Dolphins (Lagenorhynchus acutus) suffer equally from mishap and disease. Refloating was attempted for 23% of animals, with an apparent success rate of 83%, although there are no data on long-term survival. Neither sex nor age of the refloated animals was found to be an indicator of subsequent short-term survival.Key Words: cetaceans, Atlantic White-sided Dolphin, Lagenorhynchus acutus, Harbour Porpoise, Phocoena phocoena, Longfinned Pilot Whale, Globicephala melas, incidental catch, stranding, Maritimes, Canada. NEMIROFF, WIMMER, DAOUST, AND MCALPINE: CETACEAN STRANDINGS 33and Lounsbury 2005). For some rare cetaceans, most of what is known about the biology of these species has been gleaned from stranded animals (e.g., Kenyon 1961). Ideally, volunteers and paid personnel are trained to respond quickly and effectively to strandings, to coordinate refloating efforts when possible, to collect information, and to provide liaison with the public. Systematic efforts are made to collect, compile, and analyze data from all stranding events. There are four principal organizations that collect stranding information and participate in refloating attempts in the three Canadian Maritime provinces (Nova Scotia, New Brunswick, and Prince Edward Island):(1) the Marine Animal Response Society (MARS) in Nova Scotia, (2) the New Brunswick Museum, (3) the Grand Manan Whale and Seabird Research Station (GMWSRS) in New Brunswick; and (4) the Atlantic Veterinary College, University of Prince Edward Island. The Marine Animal Response Network of Atlantic Canada (MARNAC) is a cooperative effort among these groups and others.Data collected by stranding networks may be useful in monitoring the status, distribution, and seasonal abundance of species (e.g., Osborne and Ransom 1988;Ferrero et al. 1994; Evans and Hammond 2004; Norman et al. 2004;Maldini et al. 2005). For instance, in an analysis of 65 years of data collected from b...

“…Seven, probably eight, Pygmy Sperm Whale strandings have been reported prior to the present report (Piers 1923;Sergeant et al 1970;Nelson et al 1991;McAlpine et al 1997;Lucas and Hooker 2000) west coast of Newfoundland. The present report is the northern-most stranding of this species in the western Atlantic and the first within the Gulf of St. Lawrence.…”
