Transcriptomic analysis of differentially expressed genes in the larval settlement and metamorphosis of peanut worm Sipunculus nudus

Aquaculture Reports, 2020
Larval development, especially settlement and metamorphosis, has a vital influence on commercial culture during the life cycle of marine invertebrates. Sipunculus nudus, a peanut worm, is an important economic aquaculture species.

A History of the Cultured Pearl Industry [PDF]

Zoological Science, 2013
During the 18th and 19th centuries, studies of how pearls are formed were conducted mainly in Europe. The subsequent pearl culturing experiments conducted worldwide in the early 20th century, however, failed to develop into a pearl industry. In Japan, however, Kokichi Mikimoto succeeded in culturing blister pearls in 1893 under the guidance of Kakichi ...

Studies on Culture of Pearl

NIPPON SUISAN GAKKAISHI, 1949
The shell-movements of the pearl-oysters were recorded by using a weekly kymograph at the natural habitat in winter. When the water-temperature is below 7°C., the valves are completely closed; in the case of 7°-13°C., usually almost closed though often may be recognized very slight movements; in the case of 13°-15°C., the shell-movements become ...

Spatio-Temporal Variation in Growth Performance and Condition of the Winged Pearl Oyster Pteria penguin

Frontiers in Marine Science, 2021
Environmental conditions can strongly influence the growth performance of pearl oysters and affect pearl farm production schedules. Growth and condition index (CI) of two age cohorts of Pteria penguin were measured for 13 months to investigate ...

MBD4 from the pearl oyster Pinctada fucata martensii involved in immune response by binding to methylated DNA sequences

Aquaculture Reports
DNA methylation is a conserved epigenetic modification with a critical role in regulating gene expression and maintaining genomic stability. Methyl-CpG-binding protein 4 (MBD4) binds to the methylated sequences and regulates gene expression.

Comprehensive whole transcriptome analysis reveals specific lncRNA, circRNA and miRNA-mRNA networks of pearl oyster (Pinctada fucata martensii) in response to hypoxia stress

Aquaculture Reports
Hypoxia is a prevalent environmental stressor in both natural and aquaculture environments. Pinctada fucata martensii, a commercially valuable pearl oyster species, is particularly susceptible to hypoxic stress in aquaculture.

Growth and survival of Pinctada martensii (Dunker) postlarvae under concurrent variation in temperature, algal ration and stocking density

Aquaculture Reports, 2021
The growth and survival of pearl oyster postlarvae (Pinctada martensii) were studied under laboratory conditions. A face-centered central composite experimental design was used with 3 factors, temperature (18―34 °C), algal ration (5―100 cells μL―1) and ...

Different food particle sources in the pearl oyster Pinctada margaritifera and its epibionts

Aquaculture Reports, 2021
Suspended bivalve culture (e.g. longlines) transfers benthic biomass - including bivalves and various epibionts - toward the water column, creating strong trophic interactions with the planktonic compartment.
