“…Pearl production is a well-established and profitable industry that provides jobs and income to entire families and communities (Taylor and Strack 2008). Pearling activities have played a major role in the socioeconomic and cultural development of several countries in Asia and the South Pacific (Fong 2005). In Mexico, the presence of pearl oysters and pearls motivated the colonization of the Baja California Peninsula in the 16th century and contributed to the region's subsequent social and economic development Arizmendi-Castillo 2002, Cariño andMonteforte 1995).…”

“…La perlicultura (cultivo de perlas) es una industria bien establecida y redituable que proporciona trabajo e ingreso a familias y comunidades enteras (Taylor y Strack 2008). Esta actividad ha contribuido de forma significativa al desarrollo socioeconómico y cultural de numerosos países de Asia y en el Pacífico Sur (Fong 2005). En México, la presencia de ostras perleras y perlas motivó la colonización de la península de Baja California en el siglo XVI y promovió su posterior desarrollo social y económico (McLaurin-Moreno y Arizmendi-Castillo 2002, Cariño y Monteforte 1995.…”

The winged pearl oyster, Pteria sterna, sustains a growing pearl industry in northwestern Mexico, where a subtropical climate prevails. In tropical areas of Mexico, pearl cultivation may be profitable, but insufficient information on the biology and ecology of the species limits the definition of protocols for creating pearl farms. We measured absolute growth, growth rate, reproductive stages, changes in oocyte size, and size at first maturity of juvenile P. sterna cultivated in Bahía de Acapulco over one annual cycle (2009-2010), and compared their response in this tropical area with reports from subtropical areas of Mexico. We also compared the von Bertalanffy growth model with one proposed in this study for aquaculture purposes. The growth rate was higher during the first six months (5.3 mm month-1) and then decreased to 3 mm month-1 until juveniles reached a size of 60 mm in one year. Growth rates were higher in February and lower in July through September. Both models described well the growth of P. sterna, but the adjustment and the estimation of parameters was better with the proposed model. Gametogenesis started in December 2009 at 50.9 mm (males) and 59.5 mm (females); gonad development occurred continuously throughout the year with a peak in February-March (~25-26 ºC; 2.8 g L-1 chlorophyll a concentration), when the gonad index was highest and oocytes were larger. When compared to other studies conducted in subtropical areas, the species uses different strategies to channel available energy into growth and reproduction in tropical regions; P. sterna grows quickly in Bahía de Acapulco and may obtain the size necessary for grafting (70-80 mm shell height) in 15-17 months.

“…Standard financial performance of aquaculture fisheries production was used (Adams et al, 2001;Brown et al, 2002;Goode et al, 2002;Fong et al, 2005;Liu & Sumaila, 2007;Sathiadhas & Najmudeen, 2004). Data was collected for both inshore and offshore production, income and cost were calculated annually, and then the net present value (NPV) was calculated for a ten year production period.…”

“…Three years later, financial irregularities were reported at Nukuoro (Sehpin, 2005). That same year saw the development of a bioeconomic model for small-scale pearl farms that was based on production and financial data from the Nukuoro farm, along with another farm in the Marshall Islands (Fong et al, 2005). However, pearl cultivation ceased in 2009.…”

I n Micronesia, a group of more than 2,000 small islands in the western tropical Pacific Ocean, P. margaritifera oyster shells have been used by local populations and sold to itinerant traders since the 18th century (Clarke et al., 1996). Martin (1996) noted that in the 1800s, German divers gathered 50 tonnes of oysters from Chuuk Lagoon. The Japanese occupation of Micronesia (1914-1944) prompted further interest in pearl oyster resources, and shells were fished and a trial cultured pearl farm established in nearby Palau. In 1986, the FSM gained sovereignty after nearly 40 years as a U.S.-administered trusteeship. That year, 8,595 kg of black-lipped oysters were harvested in Chuuk Lagoon (Smith, 1992). Until 1987, however, there were no serious efforts to develop a cultured pearl farming industry in the area (Clarke et al., 1996). In the past 25 years there have been numerous attempts to establish commercial and community-based pearling operations. Current efforts are promising, and a variety of cultured pearl colors, including "Micronesian Blue," are beginning to reach the international market (figures 1 and 2). Black cultured pearl production from the P. margaritifera mollusk was valued at more than US$100
