Food web
ecology: I am
interested in how major ecological processes such as competition, and
predation, structure aquatic communities and in turn how these findings can
be used to improve aquaculture management and increase fish production.
Relationships between productivity and nutrient supply, zooplankton grazing
and algal abundance, and fish predation and zooplankton abundance are the
focus in this area. I aim to explore trophic interactions along the food
chain including primary producers (algae), primary consumers (rotifers,
cladocerans, copepods and oysters) and secondary consumers (fish and
crustacean). My research scales include microcosm (i.e., flasks, aquaria),
mesocosm (tanks, enclosures, cages and ponds) and field experiments in
lakes, reservoirs and costal waters.

Feeding
ecology and larval fish biology:
Research efforts are toward understanding the functional mechanisms of
growth and feeding in aquatic organisms (finfish, crustacean and oysters)
with a focus on fish larval and juveniles. Research activities involve the
studies of feeding behaviour, feeding efficiency, filtering rate, diet
selection, food preference, and ontogenetic diet shifts in fish larvae and
juveniles. In aquaculture scenarios, my interests extend to the exploration
of diel feeding rhythm, feeding frequency and growth pattern, compensatory
growth, fish cannibalism, and energy bioenergetics.

Aquaculture: Aquaculture is a field of applied science which integrates
multidisciplinary research efforts and aims to increase production
efficiency and optimise economic returns. With general interest in ecology,
I am interested in applying the basic principles of ecology and feeding
biology into aquaculture production of a variety of organisms that are
suitable for aquaculture. My research includes the following disciplines:

Fish
nutrition: Fish
growth and survival depend on the supply of adequate amount of energy to the
fish through formulated diets with an appropriate composition of protein,
lipid, minerals and micronutrients. I am interested in digestive physiology
on how fish respond to diet with a known nutritional composition. My
approach to fish nutrition is to combine feeding ecology and digestive
physiology. |

Greenwater and live food culture:
Greenwater culture involves the
culture of algae through nutrient fertilisation and the feeding of algae to
zooplankton including rotifers, cladocerans and copepods, which in turn, are
feed to fish larvae. The nutritional value of live food is a key
factor to the success of larval fish culture. I am interested in
studying the environmental and biological requirements of zooplankton
growth and the methodology to produce live food with adequate nutrition
to support the growth and survival of fish larvae.

Environmental stress:
The growth and
survival of aquatic animals are adversely affected by the stress from
the environment including temperature, light, salinity, pH, ammonia,
oxygen and pathogens. I am interested in examining the
physiological, immunological and biochemical responses of the animals to
the environmental stress of various kinds, in attempt to understand the
adaptive mechanisms involved in animals facing environmental changes. |

Ploidy
manipulation: Triploidy induction can be a useful means to improve fish growth in
aquaculture. Triploids are sterile and often lack gonadal development, which
can result in improved growth and food conversion, particularly when sexual
maturity normally occurs before fish reach market size. In this regard, I
am interested in exploring the use of ploidy manipulation to improve the
growth performance of animals that reach maturity early (e.g., yabby) or
show differential growth between sexes (e.g., catfish). |
-
Biofuel
from algae: My
interest in algal culture has gone beyond the production as a basal food to
primary consumers in aquaculture. The reliance of petroleum sourced fuels is
now widely recognized as unsustainable because of depleting supplies and the
contribution of these fuels to the accumulation of carbon dioxide in the
environment. Renewable, carbon neutral, transport fuels are necessary for
environmental and economic sustainability. Algae
have
considered one of the most promising sources especially for biofuel
production for three main reasons (1) the yields of oil from algae are
orders of magnitude higher than those for traditional oilseeds, (2) algae
can grow in places away from the farmlands and this will not
compromise production of food,
fodder and other products derived from crops,
and (3) algae can be grown in sewages and next to power-plant smokestacks
where they digest the pollutants and give us oil. My research in this area
includes the study of the environmental requirements and genetic
manipulation of oleaginous algae.
