Cassandra has worked as a marine fisheries and conservation scientist in shark fisheries, management, and research across government, academia and NGOs over the past 20 years. First delving into the shark world through shark finning issues in the late 1990s, Cassandra has since been involved with Australian shark fisheries sustainability, deep water sharks’ life history (PhD), CITES capacity building for sharks and rays, and efficacy of marine protected areas for shark and ray conservation. More recently, Cassandra contributed to ecological risk assessments of southern Oceans deepwater sharks, risk summaries of all Australian sharks, and developed WWF tools to improve shark management and conservation in developing countries.

Southern Indian Ocean Fisheries Agreement (SIOFA/APSOI) - Contract Research

Ecological Risk Assessment for Deepwater Chondrichthyans

Indicative Funding
$10,012 over 1 year
Australia is obliged to fulfil elements of the Southern Indian Ocean Fisheries Agreement (SIOFA) Scientific Committee work plan to provide advice o the impacts of fishing on associated species. James Cook University undertook preliminary work to develop an ecological risk assessment (ERA) for deepwater sharks by compiling input values of species productivity attributes from the scientific literature and other sources. The ERA was then progressed at a workshop with SIOFA Contracting Parties. JCU will now provide expert review of SIOFA ecological risk assessment data, outputs and reports and assist with the preparation of a scientific paper for publication.

Fisheries Research & Development Corporation - Annual Competitive Round

Putting potential environmental risk of Australia's trawl fisheries landscape perspective: exposure of seabed assemblages to trawling, and inclusion in closures and reserves

Indicative Funding
$2,286 over 2 years (administered by CSIRO)
Australian trawl fisheries need to ensure they meet legislative requirements to ensure they have no unacceptable impacts on ecosystems. This project aims to qualitatively describe the potential risk implications for habitat forming biota in assemblages with high exposure to fisheries. The planned outcomes include an Australia-wide collaboration providing regionally relevant clarification of the landscape-scale footprints of trawling, and exposure and protection of demersal assemblages with respect to trawling. The outputs are expected to contribute to environmental assessments that are more comprehensive yet more rapid with lower cost; and ultimately to reduced ecological risk, improved sustainability, social licence and market perception.

Life history attributes data for deepwater sharks ecological risk assessment

Indicative Funding
$25,454 over 1 year
This project will gather information on the life history of deepwater shaks from the Pacific and Indian Oceans for use in developing a qulaitative isk assessment for deepwater fisheries.
