Mortality trends
of stranded marine mammals on Cape Cod and southeastern Massachusetts, USA, 2000
to 2006. Diseases of Aquatic Organisms 88: 143-155.
ABSTRACT: To
understand the cause of death of 405 marine mammals stranded on Cape Cod and
southeastern Massachusetts between 2000 and 2006, a system for coding final
diagnosis was developed and categorized as (1) disease, (2) human interaction,
(3) mass stranded with no significant findings,(4) single-stranded with no
significant findings, (5) rock and/or sand ingestion, (6) predatory attack, (7)
failure to thrive or dependent calf or pup, or (8) other. The cause of death for
91 animals could not be determined. For the 314 animals that could be assigned a
cause of death, gross and histological pathology results and ancillary testing
indicated that disease was the leading cause of mortality in the region,
affecting 116/314 (37%) of cases. Human interaction, including harassment,
entanglement, and vessel collision, fatally affected 31/314 (10%) of all
animals. Human interaction accounted for 13/29 (45%) of all determined gray seal
Halichoerus grypus mortalities. Mass strandings were most likely to occur in
northeastern Cape Cod Bay; 97/106 (92%) of mass stranded animals necropsied
presented with no significant pathological findings. Mass strandings were the
leading cause of death in 3 of the 4 small cetacean species: 46/67 (69%) of
Atlantic white-sided dolphin Lagenorhynchus acutus, 15/21 (71%) of long-finned
pilot whale Globicephala melas, and 33/54(61%) of short-beaked common dolphin
Delphinus delphis. These baseline data are critical for understanding marine
mammal population health and mortality trends, which in turn have significant
conservation and management implications. They not only afford a better
retrospective analysis of strandings, but ultimately have application for
improving current and future response to live animal stranding.
