What I am doing is measuring the arms and body length of the sea urchin larvae using the software Fiji ImageJ. Next step is to obtain the orientation angle data by examining the video using Matlab. It is interesting that the larvae did not seem to be dizzy when being flip over again and again!

This study is to test whether the different physical environments of deep sea (abundant with blue light) and coastal area (presence of blue and red light) would led to a different visual system of zooplanktons in coastal area than deep sea. Samplings with new designed light traps is holding in Hong Kong to test whether the blue light can attract more zooplankton than red light in coastal area. This project will be finished on late January 2016.

I am currently working on the effect of microplastics found in toothpaste on larval sea urchin H. crassispina. I am testing if human daily products would negatively impact the mortality rate, food ingestion rate and growth rate of the larvae. Hopefully, I can find the possible effect and reduce it in the marine environment.

I am working on the effects of micro-plastic on larval sea urchin, H. crassispina. Mortality rate, growth rate of larvae and clearance rate of food are measured to examine the effects. The capability of capturing and ingesting micro-plastic are observed under fluorescence microscopy, and the retention time of plastic is estimated.

It is a project about the long term effect of microplastic on Crepidula onyx. Growth rate, injection rate, and sex ratio are the major parameters for examining the effects. Apart from that, the reversibility of the effect was investigated by only exposing the organism to microplastic in particular life stage.

I am a final year student in ENVS program working on a Final Year Project in Dr. Chan’s lab. I am interested in how ocean acidification affects the marine planktonic organisms in terms of mortalities and performances. My project title is 'The effects of ocean acidification on mortality and performance of Tigriopus japonicus.
