Pup counts using a UAS for Steller Sea Lions (Eumetopias jubatus), California Sea Lions (Zalophus
californianus), and Northern Fur Seals (Callorhinus ursinus) increased accuracy of the counts while minimizing disturbance to pinnipeds as well as numerous species of nesting sea birds.

Additional factors that make Dungeness crab a good candidate for comparing discard mortality in situ and in the laboratory include evidence that they 1) are agonistic and cannibalistic (Jacoby, 1983; Fernandez, 1999; Barber and Cobb, 2007), 2) are often preyed upon by seabirds and California sea lions (Zalophus
californianus) upon their return to the water, and 3) like many crustaceans, can be difficult to maintain in captivity owing to stress, disease, and sensitivity to temperature and water quality (Burton, 2001; Barrento et al., 2008).
Although Shane (1994) felt that the shooting was mainly directed at California sea lions (Zalophus
californianus), it must be assumed that this shooting caused some additional level of mortality for pilot whales, and because the interactions typically occurred at night, they may have easily gone un-noticed.
A single California sea lion, Zalophus
californianus, was also captured and released alive and alert following a brief (15 min) period on the line.
