25-30 KShs (US$ 0.35-0.40) per coral fragment (on racks). However, further studies have to be performed before transplantation of corals by these methods can be considered a feasible rehabilitative technique for degraded reefs. Different transplant methodologies such as the use of cement will also be considered for evaluating the strengths and weaknesses of specific methods under different contexts, including economic.
