Distribution of Polycyclic Aromatic Hydrocarbons in Farmed Oysters (Crassostrea gigas) around Tongyeong, Korea
Cho, Sang-Man ;
The Korean Journal of Malacology, volume 26, issue 2, 2010, Pages 107~114
To evaluate the culture conditions in oyster-farming waters, chemical and biological measurements were made in seawater and oysters from six bays around Tongyeong in November and December 2003. Nutrient levels in the seawater were higher in the western area than in the eastern area, in contrast to particulate organic matter and dissolved oxygen levels. The mean total polycyclic aromatic hydrocarbon (
PAH) content of the oysters was 194.5-375.9 ng/g dry weight, with four-ring compounds constituting 34.1%-79.6% of PAH. Despite wide temporal variations, a "western > eastern" spatial distribution of PAH was apparent. These low concentrations of PAHs indicate that Tongyeong waters are pristine in terms of PAH contamination. Among the hemocytic biomarkers, only lysosomal activity was significantly reduced in Hansan-Goje Bay, but did not correlate closely with PAH content. This finding indicates that the impact of PAH on cultured oysters is negligible around Tongyeong waters.

For industrialization of the hard clams, Meretrix petechiails (Lamarck), spawning was induced per spawning induction technique in the artificial maturation group administered of parent maturation control and the natural maturation group of which parents were transported for artificial spawning per time period. Then, fertilization rates, hatching rates and D-shaped larva development rates were investigated. In addition, growth and survival rates of larvae were investigated per larva breeding technique. The results of spawning induction by exposure in the artificial maturation group indicated that response rates were relatively higher at 23% and 32% respectively at the 4th hour and the 8th hour of exposure. In terms of water temperature increase, responses began only when the temperature reached
or higher. In the experiment group administered with both exposure and water temperature increase techniques, response rate was found to be 45% or higher at the 4th hour of exposure and the temperature of
. At the temperatures of 29, 30 and
, significant differences were not observed. Therefore, it was indicated that the response rates of parent hard clams were higher toward water temperature increase than exposure time. As for spawning induction per time period of the transported parent group, response rate and D-shaped larva development rate were the highest at 67.6% and 96% respectively on August 6, 2009. In terms of water temperatures during larva breeding experiment, growth was faster as water temperature was higher. In addition, growth and survival rates were relatively higher at the salinity of 25. In terms of stocking density, growth and survival rates were relatively higher at 5 inds./mL.

The location of the style sac and morphology of the crystalline style were described morphologically in three bivalve species (Tegillarca granosa, Mytilus galloprovincialis and Saxidomus purpuratus) which inhabited in different area. The style sac of them was connected to the posterior stomach. There was the crystalline style in the style sac. The crystalline style of three species was long circular cone of translucent gelatin form, which was hard and elastic. There was a red-yellow and spiral filament inside the crystalline style of Tegillarca granosa and Mytilus galloprovincialis. A white and long tube was located from basal portion to the end of crystalline style in Saxidomus purpuratus. RLC (relative length of crystalline style) of Tegillarca granosa, Mytilus galloprovincialis and Saxidomus purpuratus was 47.69, 48.97, 64.20% and RWC (relative weight of crystalline style) was 0.54, 0.54, 0.39%, respectively.

The structure of the ovary, ultrastructure of oocytes and morphological characteristics of vitellogenesis during oogenesis in female Gomphina veneriformis were investigated in clams collected from coastal waters of Samchok, Gangwon-do, Kore. In the previtellogenic oocytes, the Golgi complex was involved in the formation of a number of vacuoles. In the early vitellogenic oocytes, lipid droplets appeared among the Golgi complex, endoplasmic reticulum, and mitochondria in the cytoplasm of the oocyte were involved in the formation of lipid droplets. Coated vesicles, resulting from endocytosis appeared at the basal region of the early vitellogenic oocyte. The uptake of nutritive materials in the coated vesicles formed by receptor-mediated endocytosis appeared through the formation of coated endocytotic pits on the oolemma. In the late vitellogenic oocytes, large yolk granules were formed by a combination of small yolk granules. In the mature oocyte, a mature yolk granule in composed of three components: crystaline core, electron lucent cortex, and a limiting membrane. According to cytological and histological observations, vitellogenesis occurred by way of endogenous autosynthesis and exogenous heterosynthesis. Autosynthesis involved the conbined activities of the Golgi complex, mitochondria, rough endoplasmic reticulum, whereas heterosynthesis involved endocytotic incorporation of extraovarian precursors at the basal region of the early vitellogenic oocyte. The follicle cells which was attached to oocytes, were involved in the development of the previtellogenic and early vitellogenic oocytes as a kind of nutritive cells containing a number of glycogen particles and lipid droplets in the cytoplasm.

The Web-based the genus Haliotis SNP database was constructed on the basis of Intel Server Platform ZSS130 dual Xeon 3.2 GHz cpu and Linux-based (Cent OS) operating system. Haliotis related sequences (2,830 nucleotide sequences, 9,102 EST sequences) were downloaded through NCBI taxonomy browser. In order to eliminate vector sequences, we conducted vector masking step using cross match software with vector sequence database. In addition, poly-A tails were removed using Trimmest software from EMBOSS package. The processed sequences were clustered and assembled by TGICL package (TIGR tools) equipped with CAP3 software. A web-based interface (Haliotis SNP Database, http://www.haliotis.or.kr) was developed to enable optimal use of the clustered assemblies. The Clustering Res. menu shows the contig sequences from the clustering, the alignment results and sequences from each cluster. And also we can compare any sequences with Haliotis related sequences in BLAST menu. The search menu is equipped with its own search engine so that it is possible to search all of the information in the database using the name of a gene, accession number and/or species name. Taken together, the Web-based SNP database for Haliotis will be valuable to develop SNPs of Haliotis in the future.
