Adsorption of minerals on the isolated mantle of Patinopecten yessoensis
Fisheries Science, 2002: The isolated mantle of scallop (Patinopecten yessoensis) was shown to adsorb minerals (Zn, Ca, Mg, Fe, Cu, Ni and Co) to more than 1% upon treatment with mineral solution. The amounts of adsorbed Zn, Ca and Mg were 44.3, 47.4 and 15.5 mg/g dry weight, when the mantle was treated with 5% ZnSO4, CaCl2 and MgSO4 solutions at room temperature ...

In the present study, two polysaccharides, SVP2-1 and SVP2-2, were isolated from Patinopecten yessoensis viscera and purified by using DEAE-52 cellulose and Sepharose CL-6B. Both SVP2-1 and SVP2-2 could extend activated partial thromboplastin time (APTT) and thrombin time (TT) and inhibit the transformation of fibrinogen into fibrin (FIB) concentration-

Some glycolytic metabolites in the adductor muscle were measured after transfer of scallops from aerobic to anaerobic saltwater for 12 h. The level of octopine increased gradually during the initial 3 h incubation, and thereafter the level increased rapidly up to 12 h. The ATP level also did not show any significant change for the initial 3 h, and then

Inbreeding often causes a decline in biological fitness, known as inbreeding depression. In genetics study, inbreeding coefficient f gives the proportion by which the heterozygosity of an individual is reduced by inbreeding. With the development of high-throughput sequencing, researchers were able to perform deep approaches to investigate which genes ...

Development of EST-SSRs in scallop (Patinopecten yessoensis) from sequence database
Conservation Genetics, 2008Patinopecten yessoensis is a kind of cold water shellfish, and is an important economic species in China. In our study, we developed and evaluated simple sequence repeat (SSR) markers of P. yessoensis. Characteristics of 11 EST-SSR loci were investigated using 40 P. yessoensis individuals. The number of alleles per locus ranged from two to five.

Involvement of prostaglandins in the spawning of the scallop, Patinopecten yessoensis
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1989Abstract 1. A high performance liquid chromatography (HPLC) using 9-anthryldiazomethane (ADAM) as a fluorescent reagent was employed to detemine the levels of endogenous prostaglandins (PGs) in the central nervous system, gonad, gill and hemolymph of the scallop, and the authors have also verified the involvement of PGs during spawning induced by u.v.

Stock enhancement of the Japanese scallop Patinopecten yessoensis in Hokkaido
Fisheries Research, 2006Prior to the early 1940s, harvests of scallops from Japan fluctuated from ∼10 to 80,000 tonnes per anum. However, the fishery collapsed in 1945 and production remained at chronically low levels (

Diseases of cultured Japanese scallops (Patinopecten yessoensis) in British Columbia, Canada
Aquaculture, 1992Abstract Preliminary grow-out studies with Patinopecten yessoensis in British Columbia, Canada, revealed the presence of at least three pathogens. At one location, the shell boring polychaete, Polydora websteri , was responsible for 84% mortality. Most surviving scallops were stunted and regrowth of the shell was often abnormal.

Structure of Patinopecten Yessoensis Shell is a Biomimetic Example of Composite
Advanced Materials Research, 2012Shell is a natural composite material with excellent mechanical property. it is a model of biomimetic composites. In the paper, the morphology of the scallop (patinopecten yessoensis) shell was observed by SEM. The results are shown that the shell is composed by the tertiary structure.

Isolation and characterization of melanin pigment from yesso scallop Patinopecten yessoensis
Journal of Ocean University of China, 2017Melanin is one of the essential compounds in the pigments of molluscan shells. However, the effects of melanin on color variations in molluscs are largely unknown. Our previous study suggests that Yesso scallop Patinopecten yessoensis might contain melanin pigment in the dark brown shell.
