—ABSTRACT: To better record and characterize mortality in the declining population of dugong (Dugong dugon) in southeast Queensland, Australia, animals were collected and brought to the University of Queensland for postmortem examination. Fifty-five animals were examined over a 14-yr period. Human activities commonly caused the animal death. Several deaths were attributed to primary or secondary infections and idiopathic and degenerative diseases. A significant proportion of animals were found to have nonspecific signs of chronic debility, but the causes of disease and mortality in these cases remains to be identified.

2017Impacts of marine debris and fisheries on sirenians. Chap. 18 in: Andy Butterworth (ed.), Marine mammal welfare: human induced change in the marine environment and its impacts on marine mammal welfare.

—ABSTRACT: Harmful marine debris includes land and ship-sourced waste and abandoned fishing gear from recreational and commercial fisheries; these forms of debris are making their way into waterways and oceans with increasing frequency. For sirenians, marine debris and fisheries pose a significant risk to their well-being through entanglement, ingestion and hunting, both legal and illegal, as well as through more indirect ways, such as changing social structures and creating orphans through loss of cohorts. This chapter addresses the welfare impacts of marine debris and fisheries on sirenians. It also explores the changes in attitude that are occurring in many of the stakeholders involved and how these are translating into positive outcomes.
