My name is Tim Pickering at the University of the South Pacific in
Fiji, and I have just begun supervising an MSc student Dilpreet
Kaur on a "live rock aquaculture" topic in collaboration with Walt
Smith International Inc, with the aim of getting artificial substrate to
encrust with corallines in the quickest possible time. We have
considered three approaches;
(1) a "site selection" approach, through monitoring of natural
recruitment and growth between reef zones and seasons using
ceramic tiles, to identify any site-related or seasonal "hotspots" for
(2) vegetative propagation, in which we super-glue coralline-algae
fragments onto the artificial substrata before placement on the reef;
(3) induction of spore release from "mother rocks" onto substrata in
the laboratory by manipulating light intensity, daylength and/or
temperature, as you would for any red seaweed.
Currently we are focussing on (1) and (2), and are only a couple of
months into the study at this stage.
I hope this assists. Why are you doing this? Is it a scientific
study, or a commercial project?
