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.

[Temporal dynamics of genetic diversity of Japanese scallop Mizuhopecten yessoensis (Jay, 1856)].
Izvestiia Akademii nauk. Seriia biologicheskaia, 2010The season and age-related dependence of the distribution of the frequency of alleles and of five polymorphous loci have been studied for eight cultivated samples of the Japanese scallop M. yessoensis (Jay) from Alexeev Bay (Popov Island, Sea of Japan) using polyacrylamide gel electrophoresis.

To examine the genetic structure of Japanese scallop populations (Mizuhopecten yessoensis) in Hokkaido prefecture, Japan, and compare it with those in the Aomori prefecture, we applied a method for lineage analysis based on sequence variation in a mitochondrial DNA segment (NcR2).

Russian Journal of Marine Biology, 2005
Behavioral experiments were conducted on two bivalve species—the Japanese scallop Mizuhopecten yessoensis and the Swift scallop Chlamys swifti—to elucidate the role of their abdominal sense organ (ASO) in directional sensitivity to water-borne vibrations. The thresholds were determined at 140 Hz.

Biology Bulletin, 2011
The temporal diversity of 11 morphological features of both shell valves in eight cultivated samples of the Japanese scallop M. yessoensis from Alexeev Bay (Popov Island, Sea of Japan) at different ages and from different generations was analyzed. The sample diversity with respect to each investigated feature was observed. The sample differences in the

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 (

There was a negative relationship between the number of parasitic copepods (Pectenophilus ornatus) and the dry weight condition index of the infected Japanese scallop (Patinopecten yessoensis) cultured in the Tsugaru Strait of northern Japan. The parasite is considered a serious pest of the commercial bivalve in cases of heavy infection.

Two novel elements (CFG1 and PYG1) of Mag lineage of Ty3/Gypsy retrotransposons were cloned from Zhikong scallop (Chlamys farreri) and Japanese scallop (Patinopecten yessoensis). The total length of the CFG1 element is 4826 bp, including 5'-LTR (192 bp), the entire ORF (4047 bp) and 3'-LTR (189 bp).

Twenty polymorphic microsatellite loci were isolated from the Japanese scallop (Patinopecten yessoensis) using a method of hybridizing twice. The genetic diversity was analyzed by these microsatellite markers in field specimens from Zhangzidao Island in Liaoning Province, China.

To study the paralytic shellfish toxins (PSTs) depuration in Japanese scallop Patinopecten yessoensis in natural environment, Japanese scallops naturally contaminated with paralytic shellfish poisoning (PSP) toxins in the Dayao Bay in the northern Huanghai Sea are transited to Qipanmo waters in the Bohai Sea of no reported PSTs incidents.
