The internal shell morphology of the blue mussel, which were collected from Korea and Japan were studied. The range of the mean ratio between anterior adductor muscle scars to shell height in each locality were between 62.47 in Yongdok to 54.17 in Uichang. These values were very similar to that of M galloprouincialis in Mediterranean than that of M edulis in Europe. And the range of the mean ratio between hinge plate length to shell height were between 61.31 in Jukbyon to 56.15 in Otuschi. Also these values were similar to that of M. galloprovincialis in Mediterranean. Based on the mean ratio between anterior adductor muscle scars and hinge plate length to shell height, it was suggested that the Korean and Japanese blue mussel is certainly identical to the Mediterranean species, Mytilus galloprovincialis.

Mussels are stubborn organism attached to solid substrate by byssus threads and caused operational problems in utility of power generating stations. Sole and combined usage of ultrasonic (28 kHz- and 42 kHz- frequencies) and hydrogen peroxide ($H_2O_2$) has studied for control of blue mussel larvae and adult stage in seawater condition. A theoretical wo rking model using disinfection (Chick and Watson type) approaches is presented based on helpful results of experiments. This study also demonstrate that the combined treatment (ultra-sonication with $H_2O_2$) is overall highly efficient than individual treatment would, but on the basis of exposure time, the ultra-sonication was the most efficient among them. Therefore the development of sole and combined technique might be effective practical mitigation strategy against mussel attachment for water handling facilities.

The levels of heavy metals (total-mercury, cadmium, lead and chromium) in shellfishes, such as oyster (Carassostrea gigas), blue mussel (Mytilus edulis), arkshll (Scapharca broughtonii) and little neck clam (Ruditapes philippinarum), were determined. The samples were collected from 11 stations for oyster and 12 stations for blue mussel in the South Coast of Korea, and little neck clam and arkshell were collected from Koheung and the Kangjin Bay, respectively, during 1999 to 2000. The average concentrations of heavy metal in 4 different species of shellfishes analyzed were ranged from 0.007 to 0.009 ${\mu}g/g$ for total-mercury; 0.232 to 0.559 ${\mu}g/g$ for cadmium; 0.107 to 0.220 ${\mu}g/g$ for lead; and 0.116 to 0.364 ${\mu}g/g$ for chromium on wet basis. The highest level of total-mercury, lead, cadmium, and chromium in the samples analyzed were all below the quarantine limit of the Korean regulation and guideline established by the U.S.Food and Drug Administration for human consumption. The levels of heavy metals in the samples were negligible, which could be endogenous. It was elucidated that oyster was able to accumulate 2-times more cadmium than blu mussel in this study.

We report on the seasonal fluctuation of a Poecilostomatoida copepod, Pseudomyicola spinosus associated with the blue mussel, Mytilus galloprovincialis in the Yongsan River estuary (34$^{\circ}$47N, 126$^{\circ}$27'E). P. spinosus has four generations a year, seasonally succeeding each other. The generation that occurs during summer has the highest number of individuals. From June to October with the exception f September, males dominated while female outnumbered from November to May with the exception of January. It is possible to find ovigerous females all year with the exception of February. The largest number of ovigerous females occurs a month earlier than copepodids do. The percentage of C1 to C3 is approximately 4% of the total number of copepodids, indicating that in situ infestation by copepodids mainly occurs in C4 stage.

Mitochondrial DNA (mtDNA) from 54 specimens of the blue mussel (Mytilus edulis) species complex sampled from the southern coast of Korea was assayed for polymorphism with a portion of the COIII gene (336 bp). Fifteen haplotypes were found. PAUP, one-step networks, and PHYLIP analyses revealed the presence of two clearly differentiated mitochondrial clades (termed clades B and E), separated by 3.6% of minimum sequence divergence. The distribution pattern of the species appears to be consistent with category II of the phylogeographic pattern sensu (Avise et al., 1987): the presence of two discontinuous and distinct mtDNA genotypes in the same geographic region. This unusual mitochondrial polymorphism was explained by the presence of the Mediterranean species, M. galloprovincialis, possessing mtDNA of both M. galloprovincialis and M. edulis.

Blue mussels (Mytilus edulis) are widely distributed among the world's oceans in various habitats. The purpose of this study was to investigate the effects of freeze-drying on the antioxidant and antigenotoxic activities of blue mussels collected in the Gyeongnam coast area of Korea. Raw (RM) and freeze-dried blue mussel flesh (FRM) were extracted with ethanol, methanol, and water. Antioxidant activities were evaluated on the basis of DPPH radical scavenging activity, oxygen radical absorbance capacity (ORAC), cellular antioxidant capacity (CAC), and antigenotoxic activity (comet assay). Except for the water extract, RM and FRM showed DPPH radical scavenging activities, which increased upon freeze-drying in MeOH extract. The highest ORAC value was observed in water extract of RM and MeOH extract of FRM. CAC was protected against AAPH-induced oxidative stress in HepG2 cells by both RM and FRM extracts. Freeze-drying lowered ORAC value of water extract, whereas it increased CAC activity, suggesting that antioxidant activities varied according to the generated radicals. All extracts from RM and FRM showed antigenotoxic activities by reducing $H_2O_2$-induced DNA damage in human leukocytes. Freeze-drying had no effect on antigenotoxicity of blue mussels. Taken together, these results indicate that blue mussels possess antioxidant and antigenotoxic properties, and freeze-drying might be a useful processing method for blue mussels to retain their maximum physiological potential as a functional food.

This study was performed to describe the influence of temperature on the clearance rate and ingestion rate of the blue mussel, Mytilus galloprovincialis with three food organisms and habitat location (shell size) of mussel. Food organisms used in this experiments were Isochrysis galbana, Chaetoceros didymus and Prorocentrum dentatum. The size of mussels inhabiting higher midlittoral zone was smaller than those of lower midlittoral zone. Regardless of the kind of food organisms, filtration rates and ingestion rates of higher midlittoral mussels were higher than those of lower midlittoral mussels in experiment temperature conditions. The variation of filtration rate and ingestion rate showed same tendency with temperature. Filtration rates and ingestion rates increased with temperature, and recorded maximum values at $20-25^{\circ}C$ of temperature, and thereafter decreased gradually. Theoretical optimum temperatures showing maximum filtration rates and ingestion rates estimated from polynomial regression curves were also in the range of $20-25^{\circ}C$. Blue mussels showed different variation of filtration rate and ingestion rate with the kind of food organisms. Filtration rates and ingestion rate based on cell number were similar regardless of habitat location(tidal elevation) and food organisms. Ingestion rates based on carbon content showed very high values in case of P. dentatum beside I. galbana and C. didymus as food organism.
