Public
The experimental krill research program is focussed on obtaining life history information of use in managing the krill fishery - the largest Antarctic fishery. In particular, the program will concentrate on studies into schooling, growth, aging, behaviour and reproduction of krill as well as into the operation, behaviour and trends of the krill fishery.

Project objectives:
To investigate key aspects of the biology of Antarctic krill and its management utilising the facilities at the Australian Antarctic Division.

Taken from the 2008-2009 Progress Report:
Progress against objectives:
We succeeded to take krill larvae reproduced in-house last year up to adult stage (external maturity) for the first time in our research laboratory (the second facility ever outside Antarctica), which means that last year's larvae reached maturity within a year in our aquarium, compared to 2-3 years in the wild, however spawning from this population is yet to be recorded. We also had successful reproduction this year and currently these animals are at late larval stage. We have now succeeded in reproduction two years in a row and have established the technique. This is a major step forward in closing Antarctic krill's life cycle in our aquarium. This achievement makes us the only research facility outside Antarctica to be able to conduct live krill experiments for the entire life stage and contribute information on biological parameters important for krill management.

Taken from the 2009-2010 Progress Report:
Progress against objectives:
This year for the first time we have succeeded in closing the entire krill life cycle in our research laboratory (the second facility ever outside Antarctica. We also achieved successful reproduction this year and currently these animals are at the late larval stage. We have now succeeded in krill reproduction for three years in a row and have firmly established the technique. This achievement makes us the only research facility outside Antarctica to be able to conduct live krill experiments for the entire life stage and contribute information on biological parameters important for krill management.

Taken from the 2010-2011 Progress Report:
Public summary of the season progress:
Understanding how krill may respond to various environments is the fundamental information to predict the future of krill centric ecosystem under the climate change. The project's current focus is to study impacts of ocean acidification on krill. The AAD aquarium facility for ocean acidification study is continuing to be upgraded to increase its capacity and stability to undertake its experiments at larger scale. Negative impacts of ocean acidification on krill has been investigated and the range of CO2 level fatal to krill embryonic development was broadly identified, and was published for the first time.

Taken from the 2008-2009 Progress Report:

Variations to work plan or objectives:
We started conducting experiments to evaluate effects of rising CO2 concentration to krill larval development. This year we also conducted long-term CO2 exposure experiments using post larval krill. This was pursued in collaboration with our Japanese counterparts (Prof. Ishimatsu and Dr Kurihara).

Field work:
No field work was undertaken this year but a population of live krill (~25,000 individuals) were captured on return from V3 and the aquarium is currently full at the time of writing.

Laboratory activity/analysis:
Study on effect of CO2 on larval and post larval Krill.

Evaluation of effect of persistent organic pollutant on krill biology.
Analysis of krill fishery behaviour.
Analysis of flow fields using schooling krill (Contribution to analysis and writeup of experiments conducted in previous years).
Our project is a continuous multi-disciplinary study focussing on various aspects of krill. Our results are continuously being published in peer-reviewed scientific journals every year as new results are obtained.

Taken from the 2009-2010 Progress Report:
Field work:
No field work was undertaken this year but populations of live krill (~5,000 individuals in total) were captured on return from V2 and V4 and transferred to the aquarium. Many of these females were gravid and spawned once back in the aquarium, resulting with many larvae, which are currently used for ocean acidification studies on larval krill.

Laboratory activity/analysis:
Study on effect of CO2 on larval and post larval Krill.
Analysis of krill fishery behaviour.
Experimental study on over-wintering strategy of krill.
Analysis of underwater footage of krill aggregations.
Krill fishery data analysis.
Experiments on the effects of environmental condition in seasonal maturity cycle of krill.

Our project is a continuous multi-disciplinary study focussing on various aspects of krill. Our results are continuously being published in peer-reviewed scientific journals every year as new results are obtained.
