  • 가리비류 4종 - 큰가리비(Patinopecten yessoenensis), 주문진가리비(Chlamys swifti), 비단가리비(Chlamys ferreri ferreri), 해가리비(Amusium japonicum japonicum) -을 한국 5개 지역에서 채집하였고 중국산 비단가리비를 시장에서 구입하여 실험에 사용하였다. 총 7개 동위요소에 대한 starch gel 전기영동을 실시한 결과, 8개 유전자가 관찰되었다. 유전적 유사도는 비단가리비 3집단이 가장 가까운 관계를 보였고, 주문진가리비와 큰가리바가 유전적으로 서로 가까운 그룹으로 분류되었다. 이 그룹과 비단가리비가 0.595의 유사도를 보였으며 해가리비가 나머지 3종과는 유사도가 0.541로 가장 멀었다.

  • Sequences of partial 18S rDNA have been analyzed to elucidate genetic diversity of scallops collected around Korean sea, The scallops used in genetic comparison are Argopecten irradians concentricus, Amusium japonicum japonicum, Chlamys farreri farreri, Chlamys (Swiftopecten) swifti and Patinopecten yessoensis. The 18S rDNA sequences were aligned by Clustalx program. Phylogenetic tree was drawn by Treecon program, The scallops were divided into two groups-the Family Pectinidae containing A. japonicum japonicum and the Family Propeamussiidae containing Argopecten, Chlamys and Patinopecten genera. The Family Propeamussiidae was also divided into the Supergenera Aequipecten containing A. irradians concentricus and Supergenera Chlamys containing C. farreri farreri, C. swifti and P. yessoensis. The species of C. swifti was closer to the P. yessoensis rather than C. farreri farreri in respect to nuclear 18S rDNA sequence.

  • The author performed PCR-based genetic platform to measure the hierarchical dendrogram of Euclidean genetic distances of Korean scallop populations (KSP), particularly for Chlamys farreri, which was further compared with those of the Chinese scallop populations (CSP), by employing the with specifically designed oligonucleotide primer sets. The scallop is economically and ecologically very important bivalves in South Korea. Relatively, individuals of KSP population were fairly distantly related to that of CSP population, as shown in the hierarchical dendrogram of Euclidean genetic distances. Comparatively, individuals of KSP population were fairly distantly related to that of CSP population. Thus analysis of genetic difference between scallop populations could provide important statistics for fishery and aquaculture. Overall the results showed specific and/or conserved genetic loci between scallop populations. Information on the genetic distance of the bivalve would be helpful to understand scallop expansion or conservation in the coastal regions of South Korea. Specific markers developed by the author will be useful for the analysis of scallop population genetics and distribution in coastal region.

  • 비단가리비 (Korean scallop, Chlamys farreri)는 가리비과 (Family Pectinidae)에 속하는 부채모양의 패류로서, 1970년대 상반기부터 다량 어획되어 어민들의 소득증대에 크게 기여하였다. 그러나, 1980년대 중반부터는 자원의 감소로 인해 생산량이 급격히 감소하여 최근에는 소량 어획되고 있다 (국립수산진흥원, 1996). 비단가리비에 관한 연구로는 국립수산진흥원에 의하여 수행되었던 흑산도 근해 비단가리비의 분포생태에 관한 연구 (1973)와 비단가리비 자원조사(1995,1996) 결과만이 있을 뿐 생물학적 기초연구는 매우 부족한 실정이다.

  • Gonadosomatic index, reproductive cycle, spermatogenesis and first sexual maturity of Chlamys farreri were investigated by cytological and histological observations, from January 1998 to December 1999. The gonadosomatic index (GSI) rapidly increased in April and reached a maximum in May when seawater temperature rapidly increase. Then the GSI gradually decreased from June to August when spawning occur. Accordingly, monthly changes in the GSI in males coincide with the reproductive cycle. The spermatozoon of Chlamys farreri is the primitive type found in external fertilization species. The head of the spermatozoon is approximately $2.75{\mu}m$ in length including the acrosome measuring about $0.50{\mu}m$ in length, and its tail was approximately $20{\mu}m$, the axoneme of the tail flagellum consists of nine pairs of microtubules at the periphery and a pair at the center. Five spherical mitochondria around the centriole (the satellite body) appear in the middle piece of the sperm. The spawning period was from June to August and the main spawning occurs from July to August when seawater temperatures are greater than $20^{\circ}C$ The reproductive cycle of this species can be categorized into five successive stages; early active stage (January to March), late active stage (March to April), ripe stage (April to August), partially spawned stage (June to August), and spent/inactive stage (August to January). Over 50% of male scallops attained first sexual maturity between 50.0 and 60.0 mm in shell height, and 100% of those over 60.0 mm in shell height achieved maturity. Accordingly, we assume that male individuals begin reproduction at three years of age.

  • PCR-RAPD 표지인자를 이용하여 비단가리비와 큰가리비 그리고 해만가리비의 유전적 유연관계를 조사하였다. 60개의 random primer중 6개의 primer를 선택하여 시료들의 RAPD 양상을 비교하였다. 모든 primer들은 서로 다른 속의 가리비 종류에 대하여 특이적 RAPD band 형태를 나타내었다. 비단가리비에서는 패각 크기와 색깔의 특성이 두 집단간의 현저한 차이를 나타내었다. 그러나 RAPD 양상은 두 지리적 집단간에 유전적 차이를 보이지 않았다. 다형성 RAPD 대립인자들이 각 가리비종의 동일 집단에서 관찰되었다. 그러므로 RAPD 표지인자는 가리비를 동정하고 가리비 집단 구조를 연구하는데 유용하다고 사료된다.
