TEACHING INTERESTS
My
current teaching focuses on first year Crustacean Culture and
Professional Development, and I co-teach units including Zoology,
Physiology and Nutrition. I enjoy working with new aquaculture students
as the First year coordinator, and involvement with the Honours and
Masters, and Teaching Committees.

First
year coordinator for Bachelor of Aquaculture and Bachelor of Administration in
Marine and Coastal Conservation. Member of the NCMCRS and AMC Board of Studies
Teaching and Learning committees. Currently enrolled in the Graduate
Certificate in University Teaching and Learning, where I am interested in
problem based learning and developing authentic learning experiences for
students.
UNITS
RESEARCH INTERESTS
Aquaculture nutrition research for new aquaculture species requires effective
nutrient delivery, improving feed intake and nutrient utilisation. My research
interests involve the improvement of feed delivery and digestibility, the effects
of changing formulations on growth performance, digestive function and energy
storage in finfish and crustaceans. Recent projects have investigated fishmeal
replacement in crustacean feeds, gut physiology, digestive enzyme analysis,
protein digestibility and understanding energy metabolism in southern rock
lobster, Jasus edwardsii.
Sustainable aquaculture
A major focus in aquaculture feed development is to reduce current reliance
on fish products in aquafeeds. My research investigates the effects on animal
health and growth when fed alternative protein sources. This research includes
a focus on improving the digestibility of ingredients, and understanding
their impact on nutrient utilisation and energy storage. Recent studies have
explored feed development options for new aquaculture species, and the various
life stages during culture e.g. rock lobster phyllosoma, juvenile and adults
nutrition. Research has included investigations of nutrient requirements
[link to 2003 paper], ingredient digestibility and growth performance on
a range of protein sources. Recent student research projects have included
investigating lipid requirements for lobsters and nutrient digestion in barramundi.
Digestive physiology
Making modifications to aquafeed composition and formulations require an understanding
of the consequential changes to digestive efficiency. My research investigates
the effects of feed and ingredient composition on several processes directly
affecting digestion. This research is particularly important to gauge the
effect of fish meal replacement on the digestive health and growth performance
of aquaculture species.
Crustacean biology
Several recent studies have been undertaken to improve our understanding of
the biology of crustaceans with potential for culture and fisheries. Approaches
have a collaborative project with [Chris Bolch] to study the genetic and
morphological diversity among southern Australian Balmain bug Ibacus
peronii populations. Recent studies with [Barbara Nowak] have also investigated
relationships between health and stress parameters in wild southern rock
lobster Jasus edwardsii with those measured in aquaculture situations.
