Although little negative influence of environmental factors was detected, Email: [email protected] high temperatures during the reproduction period can be the most negative influen- tial trait. The highest tissue mass (6 g), which occurred at the 10th month of cultiva- tion, as well as a high availability of spat by artificial collectors in the coastal waters, showed that the species can be considered a good candidate for aquaculture in the tropical eastern Pacific.

An Environmental History of Nacre and Pearls: Fisheries, Cultivation and Commerce Micheline Cariño and Mario Monteforte he world history of nacre and pearl i sheries, cultivation, and trade is a vast topic. From an- tiquity to the present, it takes us on a journey from myths about the origins of the pearls and their dif erent traditional uses, to complex in- teractions between societies, economies, cul- tures, and environmental issues. Such a history T needs the support of dif erent disciplinary ap- proaches. Biological and ecological studies tell us how oysters develop and form a pearl. Socioeconomic studies of pearls i sheries show several historical constants, such as excessive i shing, a specii c organization of labor, and an unequal distribution of benei ts. Studies on the trade of nacre and pearls highlight the cultural characteristics of dif erent markets in the world. History of science emphasizes the link between the depletion of this natural resource and the scientii c investigations that led to the development of pearl oyster and pearl culture technologies. Nevertheless, the most interesting way to look at the exploitation of pearls is from the perspective of environmental history, to high- light their important role in humanity’s evolving relationship with natural resources.

  • Akoya Pearl Production from Hainan Province Is Less Than One Tonne (A
    1.2 Overview of the cultured marine pearl industry 13 Xuwen, harvest approximately 9-10 tonnes of pearls annually; Akoya pearl production from Hainan Province is less than one tonne (A. Wang, pers. comm., 2007). China produced 5-6 tonnes of marketable cultured marine pearls in 1993 and this stimulated Japanese investment in Chinese pearl farms and pearl factories. Pearl processing is done either in Japan or in Japanese- supported pearl factories in China. The majority of the higher quality Chinese Akoya pearls are exported to Japan. Additionally, MOP from pearl shells is used in handicrafts and as an ingredient Pearl farm workers clean and sort nets used for pearl oyster culture on a floating pontoon in Li’an Bay, Hainan Island, China. in cosmetics, while oyster meat is sold at local markets. India and other countries India began Akoya pearl culture research at the Central Marine Fisheries Research Institute (CMFRI) at Tuticorin in 1972 and the first experimental round pearl production occurred in 1973. Although a number of farms have been established, particularly along the southeastern coast, commercial pearl farming has not become established on a large scale (Upare, 2001). Akoya pearls from India generally have a diameter of less than 5-6 mm (Mohamed et al., 2006; Kripa et al., 2007). Halong Bay in the Gulf of Tonking in Viet Nam has been famous for its natural pearls for many centuries (Strack, 2006). Since 1990, more than twenty companies have established Akoya pearl farms in Viet Nam and production exceeded 1 000 kg in 2001. Akoya pearl culture has also been investigated on the Atlantic coast of South America (Urban, 2000; Lodeiros et al., 2002), in Australia (O’Connor et al., 2003), Korea (Choi and Chang, 2003) and in the Arabian Gulf (Behzadi, Parivak and Roustaian, 1997).

Thirty juveniles (20.0 ± 1.2 mm shell height), collected from a winter spatfall, were marked with the fluorochrome calcein and kept in the field in culture containers. After day 16, the juveniles were cleaned and their shells cut along the sagittal axis to determine periodicity of micro growth bands formed in the inner shell layers and to estimate age. During this trial, fluorescent calcein marking succeeded in individuals larger than 20 mm shell height; these formed an average of 15 micro growth bands over the 16 days, representing 1 band per day. The marker created a wide fluorescent band containing three micro growth marks, suggesting that calcein was incorporated into the shell over the first three days.

Abstract: Growht and mortality of the mollusk Pteria sterna in wild banks of Southern Baja California, Mexico. The Gulf of California nacre shell Pteria sterna is an important marine resource in Mexico, and the main species for “half” and round pearl production in the American continent. Wild spat can only be extracted legally for research or culture activities. This study calculates growth and mortality parameters for wild stocks in the eastern coast of Southern Baja California. Height’s data (353 dorso-ventral measurements) were taken from 1997 to 1999 at Santa Rosalía, Mulegé and Loreto Bay coast. The maximum length was estimated at 130.35 mm (124.22-136.48 mm, p>0.95). The length frequency data were set in a “virtual year”. Seasonal von Bertalanffy -1 growth parameters were calculated in the ELEFAN I routine, the values are: L∞ = 156.02 mm, k = 0.48 year , t0 = -0.216 years, C = 0.43, WP = 0.73. and ts = 0.5. The growth performance index was Φ’ = 4.068. The total mortality was calculated from length-converted catch curve Z = 3.34 year-1.

Admar Gonzaga, 1346, Itacorubi, CEP 88034-001, Florianópolis, SC, Brazil *e-mail: [email protected] Received December 6, 2010 – Accepted January 12, 2011 – Distributed February 29, 2012 (With 2 figures) Abstract There are no records in Brazil for the culture of Pteridae family oysters, genus Pteria and Pinctada. The intermediate culture can be considered one of the critical stages during the oyster farming. The changes in life conditions from a semi-closed environment provided by the collector to the structures utilized for the growth represents a considerable stress factor to which the animals are subjected. The goal of the present study was to evaluate the growth and survival of the pearl oyster Pteria hirundo (Linnaeus, 1758) kept in intermediate lanterns. Seeds of P. hirundo, obtained through larviculture carried out at the Marine Molluscs Laboratory (UFSC), southern Brazil were detached from the collectors, transferred and kept in an intermediate culture system (oyster lantern). During 6 months, growth (dorso- ventral height – DVH in mm) and survival (%) were evaluated. Two size classes were tested: medium (M), between 3.4 and 4.4 mm, and large (L), bigger than 4.5 mm.

  • Sustainability and Traceability in Marine Cultured Pearl Production
    Sustainability and traceability in marine cultured pearl production Inauguraldissertation zur Erlangung der Würde eines Doktors der Philosophie vorgelegt der Philosophisch- Naturwissenschaftlichen Fakultät der Universität Basel von Laurent Emmanuel Henri Cartier aus Frankreich Basel, 2014 Genehmigt von der Philosophisch-Naturwissenschaftlichen Fakultät auf Antrag von Prof. Dr. Christine Alewell: Fakultätsverantwortliche Dr. Michael S. Krzemnicki: Dissertationsleiter Prof. Dr. Henry A. Hänni: Korreferent Basel, den 22. April 2014 Prof. Dr. Jörg Schibler Dekan SUMMARY For centuries, wild pearl oysters and mussels were fished in the quest for natural pearls and shell material. This eventually led to the drastic overexploitation of oyster stocks in many areas of the globe. Scientific in- novation and entrepreneurship eventually unearthed a solution: Researchers discovered a way for humans to farm pearl oysters and induce the formation of a cultured pearl. Pearl cultivation can be one of the most prof- itable forms of aquaculture and may be carried out in isolated islands where there are otherwise very limited economic opportunities. Pearl farming is also one of the most ecologically sound forms of aquaculture, and if managed accordingly has very little impact on the natural environment. The potential for sustainable devel- opment in island economies through pearl farming is large. There is a positive link between environmental management and the long-term quality of pearls produced, and therefore an incentive for pearl farmers to operate in sustainable ways if they are to profit over time. The interdisciplinary approach of this dissertation has sought to produce research findings and linkages that can support the emergence of sustainable pearl production. Our main objective was to examine select sustain- ability questions in the context of pearl farming and investigate methods potentially useful in tracing pearls from farm to consumer.
