Pearl oyster Pinctada fucata is widely cultured to produce seawater pearl in South China, and the quality of pearl is significantly affected by its shell color. Thus the Pearl Oyster Selective Breeding Program (POSBP) was carried out for the shell color and growth traits. The black (B), gold (G), red (R) and white (W) shell strains with fast growth trait were achieved after five successive gene...
This study examines the seasonal changes of marine birnavirus (MABV) in seawater and the Japanese pearl oyster Pinctada fucata reared at different depths (2 and 15 m). Oysters and seawater were collected in 1998, and a 2-step PCR was carried out to detect MABV. Virus isolation was performed on the PCR-positive samples in the oyster. The detection rate of the MABV genome in the oyster was low du...
Mohar pearl oyster Pinctada radiata is the dominant economic species of pearl oyster in the Persian Gulf, particularly along the Iranian coastal waters. As pearling has been banned since 2006, stocks of pearl oysters has not been investigated during these years. For this purpose, conditions of natural habitats and stocks of Mohar pearl oyster in its old catch sites were surveyed in the present ...
صدف مرواریدساز محارPinctada radiata از خانواده ی Pteriidae یکی از مهم‌ترین صدف‌های مرواریدساز خلیج فارس می باشد. این مطالعه به منظور تعیین مقدار بهینه ی شوری و بررسی اثرات آن بر میزان صافی خواری صدف مروارید ساز محار با استفاده از فیتوپلانکتون Isochrys:s aff galbana در 5 تیمار شوری(20، 25، 30، 35 و 40 قسمت در هزار) و 3 تکرار صورت پذیرفت. صدف‌ها با میانگین طول کل(پشتی –شکمی) 98/6 ± 67/49 میلی‌متر...
Greece exhibits the lowest seafood per capita consumption amongst European Mediterranean countries, and investigation of consumer attitudes to new products would bridge gap among producers consumers by promoting vertical integration supply chain. However, limited information exists about preferences for bivalves in wild particular. The present study aims investigate, first time, consumers’ towa...
Atmospheric carbon dioxide concentrations have greatly increased since the beginning of the industrial age. This has led to a decline in global ocean pH by 0.1 units, and continued decline of 0.3–0.5 units is predicted by the end of 2100. Acidification of the ocean has led to decreased calcification rates and dissolution of calcareous structures in a range of marine species. Shells of the pearl...
The pearl oyster Pinctada fucata is a commercially important marine shellfish. As a result, genetic improvement and selective-breeding program have been conducted for this species. Polymorphic microsatellites are effective molecular markers to investigate molecular marker-assisted selection and genetic variance. In this study, microsatellite DNAs were screened and characterized based on the par...
Nacre, the iridescent material found in pearls and shells of molluscs, is formed through an extraordinary process of matrix-assisted biomineralization. Despite recent advances, many aspects of the biomineralization process and its evolutionary origin remain unknown. The pearl oyster Pinctada fucata martensii is a well-known master of biomineralization, but the molecular mechanisms that underlie...
