A feeding experiment was conducted to determine the effect of dietary distillers dried grain (DDG) on the growth and body composition of juvenile abalone, Haliotis discus hannai. Three diets were formulated to contain 0% (DDG0), 30% DDG (DDG1) replacing wheat flour and 30% DDG (DDG2) replacing fish meal and wheat flour. A commercial feed (CF) was also compared with experimental diets. Three replicate groups of abalone averaging $0.6{\pm}0.01g$ were fed one of the four diets for 14 weeks. The highest survival rate was observed in the abalone fed the DDG2 diet, which was higher than that of abalone fed the DDG0 diet. Weight gain, shell length, shell width and soft body weight of the abalone were not affected by dietary DDG and CF diet (P > 0.05). Proximate and amino acid composition of the soft whole body were not affected by dietary DDG and CF diet (P > 0.05). The result of this experiment suggests that DDG is a good ingredient to replace fish meal and wheat flour in the diet and could be used up to 30% in the diet without negative effects on the growth performance of juvenile abalone Haliotis discus hannai.

This study describes biological environmental characteristics in natural habitats of Haliotis diversicolor in the coastal area of Sungsanpo located in the eastern coast of Jeju-do, Korea. The field survey was monthly conducted from May 2006 to February 2007. H. diversicolor, sea urchin, turban shell and marine algae were collected by two divers using SCUBA. The species composition of demersal fishes were seasonally investigated by fish traps in 2007. During the study period, more than 67% of H. diversicolor and sea urchin were found in the depth shallower than 5 m, and more than 64% of turban shell were found in the depth deeper than 3 m. The dominant algal species in May were generally Undaria pinnatifida, Ecklonia cava, Sargassum. spp. and coralline algae. Most of demersal fishes collected by the fish traps were wrasses which have been reported as a major predator of young abalone.

This study was designed to elucidate the lipid contents, neutral lipids components and fatty acid composition in fresh shellfishes, produced in Korea. Four kinds of shellfishes including sea mussel, short-necked clam, corb shell and and ark shell were selected according to the higher sales order and cheaper retail price at fish markets in Seoul in July 1985. The results abtained were as follows; 1. The average total lipid contents in four shellfishes were 2.3% by wet weight basis. The ratios of neutrial lipid, glycolipid and phospholipid in the total lipid were 51.1 : 4.9 : 44.0 in sea mussel, 66.0 : 3.2 : 30.8 in ark shell, 37.8 : 2.2 : 60.0 in short-necked clam and 54.5 : 2.0 : 53.5 in corb shell, 2. The average value of acid value, iodine value and unsaponifiables contents of total lipids were 1.3, 217.8, 92.0 and 20.3%, respectively. 3. The composition of the neutral lipids were triglycerides, esterified fatty acids, sterylesters, free sterols and monoglycerides in four shellfishes. 4. The major fatty acid composition of total lipids were palmitic, eicosapentaenoic, docosahexaenoic and palmitoleic acids in four shellfishes. The average total unsaturated fatty acids of total lipid were 64.5%, and $\omega$-3 highly unsaturated fatty acids were 27.0%. The average p/s Ratiio were 1.3.

우리나라는 삼면이 바다로 둘러싸여 있기 때문에 수산물의 공급처인 연안에서 다양한 품목들을 양식하고 있다. 최근 연안 및 바다의 넓은 지역에 위치한 김, 전복, 어류 양식장의 정확한 위치와 시설량 파악을 위해 많은 연구들이 진행 중이며, 효율적인 어장관리를 위하여 지리정보시스템(Geographic Information System)과 원격탐사(Remote Sensing)를 이용한 양식장 시설량 판독이 필요하다. 본 연구는 보다 정밀하게 양식장 시설량을 판독하기 위하여 기존에 사용하던 해상도가 2~2.5m인 위성영상보다 고해상도인 항공영상(25cm)을 이용하였다. 김, 전복, 어류의 양식장이 모두 갖춰져 있는 완도군을 대상으로 항공영상 촬영 및 영상 보정, 어장 공간DB 구축, 시설량 판독을 수행하였다. 면허지 내/외의 시설량 분석 결과, 김, 전복 양식장의 면허지 외 시설량이 증가하였으며, 어류 양식장 시설량은 전복양식으로 전환했기 때문에 면허시설, 영상을 이용한 판독 시설량, 면허지 외 시설 모두 감소하였다. 김, 전복 양식장의 면허지 내/외 시설량 증가에 대해서는 이탈시설 및 무면허 시설에 대한 지속적인 단속과 관리가 필요할 것이다. 이처럼 양식장 시설량은 넓은 지역에 분포해 있기 때문에 고해상 항공영상을 이용하여 판독하는 것이 직접 현장조사를 통해 시설량을 산출하는 것보다 효과적이다. 본 연구는 어류 양식장의 효과적인 관리를 위하여 양식장의 정확한 위치와 시설량 산출에 항공영상을 이용하는 방안을 제시하였다.

Bokam-ri site was excavated from July 1996 to September 1998 and archaeologically assumed to be grouped with tombs of Mahan period. Among these groups, Tomb No. 3 had built up with stone chamber and found one pair of gilted footware near the jar coffin. This footware was severely corroded and cracked so transfered it gently with soil. Radiography film of this footware showed spike decorations on the bottom and fish-shapped ornament. Gilted footware was consolidated with soil using Paraloid B72 10%~15%solution and cleaned using small tools and microscope. SV427 and HV427 as epoxy resin and Araldite(rapid type) used for joining and restoring. The fore part of gilted footware was connected with nails and folded “L” shape to introduce the bottom material. Tortoise-shell design and flower ornaments appeared on the surface and fish-shaped ornaments, spikes and spangles on the bottom. It was found that 7 spikes and 5 fish-shaped ornaments remained well. Especially, Fish-shaped ornaments were firstly found in the gilted footware and appraised archaeologically important materials.

A rapid processing method for fermented sauce of favorable flavor was investigated with low-usefulness marine resources. Hydrolyzed at optimal conditions for 6 hours usuing alcalase, and separated by molecularporous membrane. It's very effective for remove bitter taste at below M.W. 100 dalton, and effective at below M.W.500 dalton. Added 2% invert sugar in fermented sauce at below M.W.500 dalton, and thermal treatment at 100$^{\circ}C$ for 30 minutes were improved flavor. Chemical composition of fermented sauce using hair tail were 80.7% of moisture, 2.2% of carbohydrate, 1.8% of total nitrogen, 1.6% of amino nitrogen and pH was 6.5. The ratio of amino nitrogen in total nitrogen was 77.8%. And chemical composition of fermented sauce used gizzard shad, kangdale, pen shell and oyster were similar to fermented sauce used hair tail. Total nitrogen were above 1.8% and the ratio of amino nitrogen in total nitrogen was 77.7∼84.2% in all fermented sauce. Amino acid contents in fermented sauce used hair tail, gizzard shad, kangdale, pen shell and oyster were 4,318.1mg%, 4,681.3mg%, 3,156.2mg% and 4,175.0mg%, respectively. And the predominant free amino acid were glutamic acid, lysine and glycine in all fermented sauce.

Corbicula fluminea, one of the 2 species in the family Corbiculidae living in the Lake Uiam, was used as an experimental material and the embryonic development and the structure of glochidia of this species were investigated. This freshwater mussels was oviparous, but some ovoviviparous: incubated their youngs in the inner-demibranchs or outer-demibranchs, however, chiefly used the inner-demibranchs as brood-pouch. The average time required from a fertilized egg to two-cell stage, veliger stage, and glochidium was 76 minutes, 3 hours, and 17 hours, respectively, The mean size of glochidium was $168{\mu}m$ in shell height, $195{\mu}m$ in shell lengh, $114{\mu}m$ in hinge legth and the form of glochidium was D-type and had no hooks or hooklets for attaching to fish like Unioidae.

Hatchery waste including infertile eggs, dead embryos in shell, dead or low grade chicks was cooked at $100^{\circ}C$ for 15 minutes and then oven dried and ground. Hatchery waste meal (HWM) thus prepared contained 44.25% protein, 4,573 kcal/kg gross energy, 3,600 kcal/kg metabolizable energy, 30% ether extract, 1.9% fibre, 14% ash, 9.8% nitrogen free extract, 7.26% Ca, 0.84%P, 1.86% lysine and 0.66% methionine with no Salmonella and E. coli. In biological evaluation trial, significantly higher weight gain was observed in ration containing 12% HWM compared with that containing similar amount of fish meal. Protein efficiency ratio on the two rations was 3.96 vs 2.85; protein digestibility, 86.02 vs 71.9; net protein utilization, 64.9 vs 42.37 and biological value, 75.37 vs 58.84, respectively, indicating better balance of amino acids in HWM compared with fish meal. Growth performance trial on broiler chicks also revealed better weight gain and feed efficiency on ration containing 12% HWM than that containing similar level of fish meal.
