Cathy Hair, Principal Research Scientist – based in Australia and Papua New Guinea

A stronger future for mariculture industries

Cathy's research focuses on the development of the commercial sea cucumber, Holothuria scabra (known as sandfish), in New Ireland, PNG. This species has been over-exploited due to its high value as bêche-de-mer. Her work is highlighting that H. scabra is an ideal candidate for aquaculture development. Production and release of cultured juveniles into traditional marine tenure areas holds great promise as a livelihood opportunity for rural, coastal and island communities. These communities can harvest and sell sea cucumbers commercially when they attain a suitable size. Cathy works with locals to develop appropriate community-based farming methods and identify the best release habitat for optimal sandfish survival and growth. She also investigates how traditional fishing communities who fished the wild sea cucumber resource will respond to this new mariculture activity.

Research areas: mariculture; sea cucumbers; community-based farming methods; and sustainable mariculture development.

Pranesh Kishore, Post-Doctoral Research Scientist – based in Fiji

Development of high-quality pearl production

Pranesh researches pearl oyster culture with particular emphasis on improving culture methods for high-quality round pearl production. He leads the development of a national spat collection program in Fiji which involved local coastal communities collecting pearl-oyster spat and selling them to pearl farmers to generate income. One of his priorities is to gradually convert some of these spat collection communities into high-quality mabѐ farms. He develops and runs community half-pearl (mabѐ) production and business skills training and leads a team which sets up community-based mabѐ farms. He is also researching the optimum conditions needed for pearl oyster growth and quality pearl production. His oversight of the team’s research activities in Fiji requires strong partnership with government, industry and community partners.

Research areas: pearl-oyster culture and biology; round and half-pearl (mabѐ) production; pearl-oyster spat collection; and sustainable community livelihood development.
