Comparative Effects of Microalgal Species on Growth, Feeding, and Metabolism of Pearl Oysters, Pinctada fucata martensii and Pinctada maxima

Frontiers in Marine Science, 2022
Pinctada fucata martensii and P. maxima are two main traditional pearl oyster species that can produce seawater pearls. Our previous study showed a higher clearance rate (CR) and growth performance in P. f. martensii than in P. maxima fed with Isochrysis galbana. In this study, the P. f. martensii and P.

Determination of Gender in the Pearl OysterPinctada margaritifera [PDF]

Journal of Shellfish Research, 2011
The pearl industry in French Polynesia is based on exploitation of natural stocks of the blacklip pearl oyster (Pinctada margaritifera). It generates an annual turnover of €90 million. Improvements in pearl quality need genetic studies to improve the populations.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Integrated histopathological, physiological, biochemical, and molecular analysis of gill responses to acute salinity stress in red tilapia (Oreochromis spp.)

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Growing freshwater scarcity in China is driving aquaculture interests toward saline‐tolerant fish species. Red tilapia (Oreochromis spp.) is a euryhaline species with strong osmoregulatory capacity, making it an ideal model for investigating stress‐induced physiological changes.

Biochemical Studies on the Pearl-Oyster (Pinctada martensi)

Journal of the agricultural chemical society of Japan, 1949
The fresh meat was divided into 6 parts adductor muscle, internal organs, mantle, gill, pedestal and mucilage, and the glycogen contents were determined according to the season. Among the fresh meat, the glycogen content is largest in the adductor muscles. The glycogen content of the mantle, gill and pedestal remajns to be about the same throughout the

Altered by Gold: A Comparative Zooarchaeological Analysis of 19th to 20th Century Chinese and British Migrants in Ravenswood, a Northern Queensland Gold Mining Town

Archaeology in Oceania, Volume 61, Issue 2, Page 312-333, July 2026.
ABSTRACT Gold discoveries transformed the 19th century British colony of Queensland, Australia, driving migration, a second wave of pastoral expansion northwards, and an increasingly diverse population. This study presents a comparative and contextual zooarchaeological analysis of British and southern Chinese food waste—globally significant migrant ...

Genetic Control of Tissue Remodeling by a Non‐Coding SNP in ITGA8 Explains Carotenoid‐Based Color Polymorphism in Marine Mollusks

Advanced Science, Volume 13, Issue 27, 13 May 2026.
In this study, the orange‐muscle giant abalone (Haliotis gigantea) is used as a model to identify a non‐coding SNP that disrupts the interaction between ITGA8 pre‐mRNA and the splicing factor ILF2, leading to altered ITGA8 splicing. These splicing changes promote carotenoid accumulation in abalone muscle through the regulation of tissue remodeling ...
