오늘날 해안의 인구 증가와 산업화로 인하여 해안의 수질오염이 날로 증가하고 있으며, 이로 인한 생태계가 파괴됨으로써 수산물 양식업에 많은 문제를 발생시키고 있다. 이러한 문제를 해결하기 위해 해상 양식장이 육상 양식장으로 이동하고 있다. 본 논문은 육상 양식장에서의 자동 먹이 공급 시스템에 관하여 설명하고자 한다. 현재의 자동 먹이 공급 장치는 먹이양의 정확도가 떨어지고 먹이 공급 모터에 의해 먹이가 부서지는 단점을 지닌다. 그러나 제안하는 시스템은 현재의 시스템과 비교했을 때 로드 셀과 밸브의 조합을 사용하여 제어함으로써 높은 정확도를 가지고 먹이를 공급할 수 있으며, 먹이를 육상 양식 수조에 안전하게 공급할 수 있다. 실제 시스템을 통한 실험을 수행함으로써 모든 상황에서 육상 양식장 수조에 먹이를 공급할 수 있음을 입증한다.

Feasibility of simultaneous removal of organic materials and nitrogen in the wastewater from fisheries processing plant was evaluated using entrapped mixed microbial cell (EMMC) process. The experiment was performed using activated sludge from municipal sewage treatment plant which was immobilized with gel matrix by cellulose triacetate. It was found the stable operation at the treatment system which is composed of anoxic and oxic tank, was possible when the organic and nitrogen loading rates were increased stepwise. The organic and nitrogen loading rates were conducted from 0.65 to $1.72kgCOD/m^3/d$ and from 0.119 to $0.317kg\;T-N/m^3/d$ with four steps, respectively. The maximum nitrogen loading rate which could satisfy the regulated effluent standard of nitrogen concentration, was $0.3kg\;T-N/m^3/d$. The removal efficiency of total nitrogen was decreased apparently as increasing nitrogen loading rates, whereas the removal efficiency of ammonium nitrogen was effective at the all tested nitrogen loading rates. Therefore, it was concluded that nitrification was efficient at the system. Nitrate was removed efficiently at the anoxic tank. whereas the nitrification efficiency at the oxic tank ranged 94.0% to 96.9% at the tested loading rates. The removal efficiencies of chemical oxygen demand (COD) and those of total nitrogen at the entire system ranged from 94.2% to 96.6% and 73.4% to 83.4%, respectively.

We conducted this study to compare the awareness and attitude of Busan housewives about consuming marine products. The survey was conducted from April 10 to May 31, 2019 by using a questionnaire. The degree of preference of seafood was higher among individuals in their 40s than those in the other age groups. Among the women in their 30s, 40s, 50s and 70s, the reason for liking seafood was 'taste', and for those in their 60s it was 'nutrition'. Overall the most common reason for disliking seafood was the 'fishy smell (37.4%)'. Conception degree of nutritive value of seafood was higher among individuals in their 30s and 40s than that for those individuals in their 50s, 60s and 70s. As for the price of seafood, the wives over 40s thought seafood was more expensive than did those wives in their 30s. The younger the individuals were, the lower was the perceived degree of safety was 49.8% of the subjects reported that the main concern for purchase was 'freshness'. The perceived degree of safety for imported seafood was better for the wives in their 60s and 70s than that for those wives in their 30s, 40s and 50s. The confidence level for local Korean seafood was higher for the wives in their 60s than that for the wives in their 50s. The degree of preference for seafood was moderate overall, except for Jellyfish. Age was positively correlated with conception for safety and dietary attitude (P<0.01), whereas age was negatively correlated with monthly food expenditure, nutrition knowledge and intake requirements (P<0.01). Preference for seafood was positively correlated with conception for safety (P<0.05), nutrition knowledge (P<0.05), dietary attitude (P<0.01), awareness for nutritive value (P<0.01) and intake requirements (P<0.01). Laws and regulations should be reinforced in order to promote eating more seafood and periodic research to determine the actual amount of consumed seafood and people's preferences should be conducted.

Fetal bovine serum (FBS) is an essential element of cell growth and can also affect the viral replication. In this study, we tried to find out whether FBS concentration affects the viral infectivity titer of IHNV and IPNV. EPC cells were suspended with MEM supplemented with various concentrations of FBS (MEM0, MEM2, MEM5 and MEM10) and cultured in 96-well plate. Each virus was 10-fold diluted virus and inoculated in 96-well plate. The highest infectivity titer of IHNV was $10^{7.88}\;TCID_{50}/mL$ in 96-well plate using MEM5 and the lowest one was $10^{7.30}\;TCID_{50}/mL$ in 96-well plate using MEM10. The highest infectivity titer of IPNV was $10^{7.47}\;TCID_{50}/mL$ in 96-well plate using MEM5 and the lowest one was $10^{6.97}\;TCID_{50}/mL$ in 96-well plate using MEM10. This study showed that not only 0% FBS but 10% FBS leads low infectivity titer of IHNV and IPNV. Therefore, it is considered that the desirable concentration of FBS is 2% or 5% for measurement of infectivity titer of IHNV and IPNV.

This study aims to determine problems of the damage investigation system of aquaculture products resulting from natural disaster and to deduce improvement plans for such problems. The main problems revealed from this study were as follows: 1) detailed damage investigation is carried out only by one particular organization, 2) for aquaculture insurance subscribers another detailed damage investigation is conducted to reveal the causes of natural disaster by a joint investigator team formed according to a different legislation with a different purpose, 3) damage investigation is usually suffered from lack of labor, budget and time due to the restriction of natural damage to a certain period of season leading to the absence of quick reaction capability for irresistible natural disasters, and 4) there are no specified procedures and protocols for deciphering causes of a natural demage. The improvement plans to find solutions for such problems are as follows: 1) for the investigation, the object, method and role of the investigation organization should be clarified by improving the present legislation, 2) investigation methods for determining the demage causes should be systematized by making a manual to minimize disputes, and 3) supports for the investigation organization should be institutionalized to guarantee sufficient budget and manpower. Under the present circumstance with continuous natural damages, smooth procedures of damage compensation would lead to the management stability of aquaculture farms.

In this study, the content of water-soluble vitamins such as vitamin B₁ (thiamin), B₂ (riboflavin), B₃ (niacin), B₅ (pantothenic acid), B₆ (pyridoxine), B₇ (biotin), B₁₂ (cyanocobalamin), and C (ascorbic acid) in dishes containing meat and seafood consumed in Korea were determined by high-performance liquid chromatography (HPLC) with ultraviolet and fluorescence detection. All analyses were performed under strict quality control of vitamins B₁, B₂, B₃, B₅, B₆, B₇, B₁₂, and C. The highest content of vitamin B₁ was observed in Bugeo-gangjeong (1.373 mg/100 g) and the highest level of vitamin B₂ (5.162 mg/100 g) was found in pig liver. Bugeo-gangjeong showed the highest content of vitamin B₃ (21.676 mg/100 g), and kkomak-muchim contained considerable amounts (43.310 mg/100 g) of vitamin B₅. Vitamin B₆ was not detected in most seafood dishes except for yangnyeom myeongran-jeot (0.274 mg/100 g) and was present at low levels or not present at all in meat dishes. The highest content of vitamin B₇ was 6.506 ㎍/100 g in saeu-jeon and kkomak-muchim showed the highest content (21.132 ㎍/100 g) of vitamin B₁₂. The highest content of vitamin C was in yangnyeom myeongran-jeot (84.508 mg/100 g). In addition, the analysis methods of each water-soluble vitamin were verified. These results showed that seafood-based ingredients in several dishes could be a good source of water-soluble vitamins.

Han In-jin (Artemisia iwayomogi Kitamura) and Cham Dang-gwi (Angelica gigas Nakai) exhibit antibacterial, antiparasitic, antifungal, and antiviral properties in vitro. In this study, mixture of the extracts of these two medicinal plants was absorbed on pellets. Thereafter, these pellets were fed to olive flounder Paralichthys olivaceus for 12 weeks at laboratory (1^st experiment) and 24 weeks at field test (2^nd experiment), and the immune activity and disease resistance properties of the extracts were examined. It was observed that lysozyme activities of plasma, spleen, and kidney improved after 12 weeks. Furthermore, when the olive flounders were artificially infected with bacterial pathogens, their cumulative mortality decreased in the group that was fed the extracts for 12 weeks compared to that in control group, and the relative percent survival also improved. This study concluded that mixture of Han In-jin and Cham Dang-gwi extracts provides disease resistance in vivo.
