Abstract

Pearl culture is a process of cultivating pearl oysters to produce pearls. It consists of collecting animals from their natural habitat, their relocation into hatcheries, the ongrowing of spat and pearl production. This paper presents the commercially most valuable pearl oyster species (Pinctada maxima, P. margaritifera and P. fucata) and the methods that are being used to cultivate them. The methods are being chosen according to specific species and environmental factors. Although bred pearl oysters eventually end up dead and their parts get sold, the development of pearl culture has significantly reduced fishing from their natural habitat and saved pearl oysters from extinction. Pearl culture also presents a significant potential for economic development of small coastal villages.
