Progress Code: completed Statement: The values provided in temporal and spatial coverage are approximate only. 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 ...
