Transferring the zebrafish larvae on an imaging platform has long been performed manually by the use of forceps or through mechanical pumping. These methods induce detrimental damages to the fragile bodies of zebrafish larvae during the transportation. To address this issue, in this work we are devising a light driven technique to transport zebrafish larvae within a microfluidic environment. In particular, an optomotor behavioral response of the zebrafish larvae was controlled through the computer animated moving gratings for their transportation within a microfluidics chamber. It was observed that with an optimum grating frequency of 1.5 Hz and a grating width ratio of 1:1, a 5 days-post fertilization zebrafish larva can be transported within minimum and maximum time periods of 0.63 and 2.49 s, respectively. This proposed technique can be utilized towards multi-automatic transportation of zebrafish larvae within the microfluidic environment as well as the zebrafish core facility.
