  • 이매패강 큰집가리비과(Propeamussiidae)에 속하는 참가리비(Patinoperten yessoensis)는 우리나라, 중국, 일본 등지에 분포하며 우리나라에서는 특히 동해안의 조하대 사니질에 서식한다. 지금은 환경변화로 동해안의 극히 일부지역에서만 출현하고 있는 실정이다. 이들 동물들의 생태조사, 연구의 일환으로 우선 본 종의 발생 생물학적 특성을 조사할 필요가 있게 되었다. (중략)

  • 참가리비는 세계적으로 성장과 품질 면에서 경제적 가치가 매우 우수한 종으로 1989년 이후 상업적인 양식이 우리나라 동해안에서 성공을 거둠에 따라 산업화 양식으로 정착되어가고 있다. 참가리비 양식과정에서 매우 중요한 자연채묘는 1980년 이전까지는 자연채묘에 관한 기술개발의 미흡으로 경제적 수준의 채묘가 이루어지지 못하였다. (중략)

  • Scallop, Patinopecten yessoensis (Jay), cultivated in the cold east coast of Kangwon region in Korea, is expected to be produced to about 50,000 tons in 2000 year. First of all, scallop should be exuviated to process for new goods. In this study, preservatives such s sorbate, lactate, benzoic acid, and lysozyme were to extend the shelf-life of exuviated scallop boiled with steam for 10 min. The addition of preservatives retarded the decrease in pH, and inhibited the productions of VBN, TMA, and TBA of exuviated scallop stored at $5^{\circ}C$ in the latter period of storage. They also inhibited the microbial growth, especially in the first period of storage. The estimated values of shelf-life of boiled and exuviated scallops for control, sorbate, lactate, benzoic acid, and lysozyme were about 22, 26, 29, 25, and 27 days, respectively.

  • Some of the scallops like Amesium balloti have an excellent level-swimming ability, i.e. they can swim about 20m by single level swimming with a maximum swimming velocity of about 1.6m/s in the sea. On the other hand, some species like Patinopecten yessoensis have longitudinal grooves on the upper and lower surfaces and others do not. Therefore, in the present study, we measure the lift and drag forces on a real scallop model (Patinopecten yessoensis) in a wind tunnel. Experiments are performed at the Reynolds number of 75,000 based on the maximum chord length, which is within the swimming condition of real scallop (Re = $30,000{\sim}300,000$). To see the effect of longitudinal grooves, we measure the aerodynamic forces on a scallop model by removing the grooves. With the grooves, the lift force increases at low angles of attack (${\alpha}<10^{\circ}$). The drag force increases slightly at all the attack angles considered. The lift-to-drag ratio is increased by about 10% at ${\alpha}<10^{\circ}$.

  • Identification of blood cells and their physological functions in the cultured scallop, Patinopecten yessoensis collected from Abashiri Bay, Hokkaido, Japan were studied by electron microscopic structure and histological observations. The physiological function of each blood cell type was studied on the basis of its cytological structure, the lysosome in the blood cell and its phagocytosis. The blood cells were classified as Type I, Type II and Type III. The morphological characteristics of each blood cell type are as follows ; Type I : The cell is oval shaped and its cytoplasm contains comparatively low electron dense materials. The oval nucleus is sometimes ramified into two nuclei. Lumps of tubular smooth endoplasmic reticula and vacuoles are distributed near the nucleus. Type II : The cell appears long and oval shaped, and its cytoplasm contains high electron dense materials. The oval nucleus does not ramify, and large numbers of sac-like smooth endoplasmic reticula and free ribosomes are developed around the nucleus. No vacuoles exist in the cytoplasm Type 1II : The cell is round in shape and the electron density of the cytoplasm is the highest among the three types of cells because of large quantities of rough­surfaced endoplasmic reticula and no vacuoles. Particularly, the nucleus reveals a wheel-like shape owing to lumps of tuberous chromatin. The cells of Type I and II seem to have the role of carrying out phagocytosis on either foreign materials such as bacteria or endogenous old cells and the transport of nutritive materials. The type III cell, which has not been found in any bivalve species of non Pectinidae, may be said to have the function of production and the secretion of protein related to some humoral defense materials.

  • The toxicity of bivalves in the Korean waters was investigated during 1987-1988. The toxicity of paralytic shellfish poison (PSP) was found in the sea mussels (Mytilus edulis galloprovincialis, M. corsucus), scallops (Patinopecten yessoensis, Chlamys farreri), tellin (Peronidia venulosa) and venus clam (Ruditapes philippinarum) among the 28 species screened. The toxicity in mussels, scallop (C. farreri) and venus clam was mainly confirmed from the samples collected around Jindong Bay in the southern coast of the peninsula, whereas the toxicities of tellin and scallop (P. yessoensis) were found in the vicinity of Pohang in the east coast. Samples from the west coast showed low levels of toxicity than those from the east arid south coasts. Although it varied with the regions, the toxicity was detected mainly during April to June, exceptionally during May to August in Pohang. The levels of toxicity were generally below the criteria of 4 mouse unit (MU)/g edible portion in foreign countries, with few exceptions.

  • The shells of Anadarac tegillarca granosa, Crassostrea gigas, Crassostrea nippona, and Patinopecten yessoensis were used for preparation of calcium carbonate with high purity. Calcium content in ash of shell was the highest $64.9\%$ in Anadarac tegillarca granosa ashed for 5 hr at $900^{\circ}C$, and followed as Patinopecten yessoensis $62.5\%$, Crassostrea gigas $62.4\%$, and Crassostrea nippona $61.5\%$. Whiteness of ash was the highest 81.6-85.8 in Patinopecten yessoensis shell. Calcium contents in calcium carbonates made with shells of Anadarac tegillarca granosa by using ammonium chloride process (ACP) and ammonium nitrate process (ANP) were higher $40.03-40.04\%$ than $39.92\%$ in Anadarac tegillarca granosa ash. Calcium content was the highest $40.04\%$ in pH adjusted calcium carbonate prepared by using ANP. Whiteness of calcium carbonate prepared by using ACP and ANP was the level of 101.0-101.5. Therefore, we estimated that the calcium carbonate made by using ACP and ANP could be used potentiality as a food additive for calcium supplement.
