Abstract
The black-lip pearl oyster,Pinctada margaritifera, used for roundpearl production in Polynesia, is generally cultured using"ear-hanging"where they are attached to a rope to form"chaplets."In other coun-tries, pearl oysters are cultured using panel (pocket) nets that are moreexpensive than chaplets but afford more protection to cultured oys-ters. Prior research has shown panel nets produce pearls of higherquality and value, potentially generating higher profits. This studyused cost-benefit analysis to compare pearl production using chaplet-based and panel net-based culture methods. Whole farm data, includ-ing gross revenues and annual production costs, fixed and variable,were analyzed. Average production cost per pearl using panel net-based culture was USD 22.47 and for chaplet-based culture was USD21.55. However, use of panel nets saved around 3,430 hr (USD6,860) of labor a year, offsetting the greater capital investment. Achaplet-based pearl farm generated USD 65,738 in annual profitscompared to USD 88,774 for a panel net-based farm. Positive cashflow was achieved 1 year earlier (Year 7) for the panel net-based farm.This is the first economic analysis of different pearl culture methodsforP. margaritiferaand evidence of profitability will support furtherdevelopment of the black-lip pearl industry in the Indo-Pacific region.
