Economics of giant clam production in the South Pacific - Fiji as a case study.

This contribution examines the economics of giant clam mariculture in the South Pacific, with special attention to Fiji. Economic and biological data are used in order to determine the internal rate of return from a small clam-farming enterprise. Under certain conditions, it is found that clam mariculture could be commercially profitable. Important factors affecting profitability are found to be (1) postharvest drip loss, (2) prices of seed clams, (3) prices of output and (4) mortality rates of clams. It is unlikely that villagers will undertake clam farming as a subsistence activity. The main interest of villagers lies in finding new commercial activities to supplement their existing subsistence production.
