. Dolphins<br />
Delphinus delphis - the common or saddleback dolphin<br />
The estimated minimum number of common (or saddleback) dolphins<br />
found in the study area during the period of highest abundance was<br />
17,606 (± 26,749, 95% CI) . The highest relative density of this<br />
species was in sampling Block G .during January and February, 1979 .<br />
Block G contains a portion of Lease Sale Area 59 . This species is<br />
not considered to be endangered . More than 30,000 common dolphins<br />
are thought to comprise the North Atlantic stock(s) of this species .<br />
Gram us riseus - Risso's dolphin or Grampus<br />
The estimated minimum number of Risso's dolphins (or Gray<br />
grampus) found in the study area during the survey period of highest<br />
abundance was 10,220 (± 10,194, 95% CI) . The highest relative<br />
density of this species was in sampling Block G during October,<br />
1979 . Block G contains a portion of Lease Sale Area 59 . This<br />
species is not considered to be endangered . No estimates of the<br />
western North Atlantic stock(s) of Risso's dolphins are available .<br />
Globicephala spp . - the pilot whale<br />
The estimated minimum number of pilot whales (both G . melaena<br />
and G) macrorhynchus ) found in the study area during the survey<br />
period of highest abundance was 11,448 (± 18,202, 95% CI) . The<br />
highest relative density of these species was in sampling Block C<br />
during July, 1979 . Block C contains a portion of Lease Sale Area 52 .<br />
Th.is genus is not considered endangered . The 1947 stock of long-<br />
finned pilot whales (G . melaena ) available to the Newfoundland<br />
fishery was estimated to consist of fewer than 60,000 individuals . No<br />
estimates of the stock size of short-finned pilot whales (G . macror -<br />
h ny chus ) in the western North Atlantic are available .<br />
Lagenorhynchus acutus - the Atlantic white-sided dolphin<br />
The estimated minimum number of Atlantic white-sided dolphins<br />
found in the study area during the survey period of highest abundance<br />
is 24,287 (± 15,146, 95% CI) . The highest relative density of this<br />
species was in sampling Block A during July, 1979 . Block A contains<br />
a portion of Lease Sale Area 52 . This species is not considered<br />
