본 연구에서는 2018년 충남지역에서 생산, 출하되는 수산물에 대해 잔류동물용의약품 실태를 조사하였다. 수산물 115건을 대상으로 식품공전 수산물 중 동물용의약품 동시 다성분 시험법으로 분석이 가능한 29종의 잔류동물 용의약품을 분석하였다. 115건의 수산물 중 9건에서 6종의 잔류동물용의약품이 검출되었으며, 검출률은 7.8%이었다. 검출된 잔류동물용의약품은 옥소린산, 엔로플록사신이 가장 많이 검출되었으며 시프로플록사신, 설파디아진, 플루메퀸, 옥시테트라사이클린이 각각 검출되었다. 미꾸라지 검체 1건에서 엔로플록사신이 잔류기준을 초과하였으나 전체적으로 안전한 수준으로 평가되었다. 그렇지만 잔류 동물용의약품 검출률이 높아지는 추세이고 종류 또한 다양해지고 있어 지속적인 모니터링이 필요하다.

Jeongamsa Sumano Stupa(Korean National Treasure No. 332) is a brick like stone stupa and it is considered that this stupa was built in the Later Silla period or in the early part of the Koryo period, considering its structure and style. This Buddhist stupa is highly significant in Korean Buddhism since it was built to enshrine Buddhist sarira reliquaries that 'Jajang' brought from China in the 7th century, according to the 『Overlooked Historical Records of the Three Korean Kingdoms,『三國遺事』』. However, the stupa was positioned at the very unique location. It was positioned not at the center of Jeongamsa Temple, but at the separate edifice. The location of Jeongamsa Sumano Stupa indicates that this stupa embodies the nature of Mahaparinirvana treasure palaces and that this stupa was recognized as a solemn symbol, which reflected a sarira faith. Jeongamsa Sumano Stupa is the only brick stone stupa built in Gangwon province. It is worth noticing that this stupa was mostly made of dolostones, found around this region, and thereby regional characteristics were reflected in this stupa. The other interesting fact about Jeongamsa Sumano Stupa is that there are many records available which include information about stupa's reconstruction, considering that there aren't many records of other stupas. The most representative records are 5 pieces of memorial stones which include information about when and on what ground the stupa was reconstructed as well as information about originators of the stupa. In conclusion, Jeongamsa Sumano Stupar could be regarded as the academically valuable material since it is considered very important and helpful for understanding not only the history of Korean Buddhist stupas, but also so many other things such as construction techniques, styles of brick pagoda and brick stone stupa, and such.

The objective of this study is to develop education programs for cultivating smart aquaculture experts through a education demand survey of industries, high school students, university (graduate) students and field workers. The industry demand analysis was conducted as an in-depth interview on representives from seven companies. Education demand surveys were conducted on 96 students and field workers in the Jeonnam region. Results on the demand survey were analyzed using frequency analysis and cross-analysis. The company representatives responded that they want to participated in internship and retraining programs to proactively secure manpowers with convergence capabilities about smart aquaculture. Seven companies preferred manpowers with basic competencies on ICT (Information and Communications Technologies) or aquaculture. The most respondents in the demand survey want to participate in the education program for experience on advanced technology, self-development and enhancement of work capability. On the other hand, some respondents said that the education is time-consuming and that the education program does not fit their level. Thus, the education program should be developed in a way to minimize the spatial and temporal limitations of education targets and to improve understanding of non-majors by reflecting the demands of human resources in the industrial field.

We analyzed the cutting mechanism of laver harvesting machine in the sea area near Gooam Port in Goheung, Jeollanam-do, and investigated the change and efficiency of laver collecting operation in the working ship. The laver working ship slides uniformly from the bow to the upper part of the laver collecting machine on the deck and cuts the wet laver attached to the bottom of the net at the blade of the havesting machine. The laver farming net, which was loaded with laver turrets on the deck by gravity and collected primitives, consisted of a ship structure that led to the stern side and into the sea. The working ship operation is in harvesting process while driving in a S-shape that is separated by one space to efficiently collect the laver net. During laver working ship operation, the speed was 0.51 m/s in the access stage, 0.56 m/s in the havesting stage, and 0.52 m/s in the exit stage. Considering the cutting edge life and production efficiency of the laver harvesting machine, it is appropriate to harvest 1.15 to 1.26 kg/rpm by operating at a rotational speed of about 700 to 800 rpm rather than forcibly harvesting the product at high speed. On the deck of the working ship, 959.7 kg of starboard and 1048.7 kg of center were 964.7 kg of port side. Based on the starboard, 9.3% of the central part and 0.5% of the port side appeared. The reason for this was due to the difference in harvest time according to the turning direction of the working ship.

살포식 패류양식해역인 진주만의 퇴적물 중 유기물과 금속의 분포 특성 및 오염상태를 파악하기 위하여 2015년 8월에 산휘 발성황화물(AVS), 강열감량(IL), 총유기탄소(TOC), 총질소(TN), 금속원소(As, Cd, Cr, Cu, Fe, Hg, Mn, Pb, Zn)를 조사하였다. 퇴적물 중 유기물과 금속원소의 농도는 패류양식장이 밀집해 있는 만의 남쪽 해역에서 높고, 우리나라 남해안의 다른 해역과 비슷하거나 낮았다. C/N비(5.7~8.0)를 기초로, 진주만 퇴적물의 유기물은 해역 자체에서 생성된 해양기원성인 것으로 파악되었다. 퇴적물 오염평가 결과, 유기물(AVS, TOC)과 금속원소(As, Cd, Cr, Cu, Hg, Pb, Zn) 농도는 우리나라의 퇴적물 기준보다도 상당히 낮았다. 또한, 금속원소 전체 농도를 고려한 오염부하량지수(PLI)와 생태계위해도지수(ERI) 결과는 패류 양식장이 밀집해 있는 남쪽 해역에서 높은 오염도를 보이지만, 대부분의 해역에서 저서생물에 약간 부정적인 생태 영향을 줄 수 있는 오염 상태였다. 그러므로, 진주만 퇴적물은 현재 유기물에 대해 서는 오염되지 않았고, 금속원소에 있어서는 약간 오염된 상태인 것으로 파악되었다.

As a first step in obtaining the minimum level of data needed to develop smart cultivation technology for Korean seaweed gim (Pyropia yezoensis), farming tests have been carried out using onshore aquaculture facilities. The aquaculture facility was built on paddy farmland on the west coast of Chungnam and received seawater from nearby sea. In this paper, we report the overall process and results of the aquaculture trials attempted in Korea's first onshore gim aquaculture facilities. In addition, the industrial possibility of gim production using the onshore aquaculture system will be discussed through the analysis of all expenses incurred in the test form.

본 내용은 최근 국내 양식 넙치에서 발생하는 연쇄구균병에 관하여 정리한 내용으로, 주요 균 종은 Streptococcus iniae, S. parauberis 그리고 Lactococcus garvieae이다. 최근 발생경향은 지금 까지 보고된 내용과 2002년에서 2017년 사이에 국립수산과학원 균주은행의 기탁균주에 대한 정보를 기초자료로 검토하였다. S. iniae와 L. garvieae는 계속 검출빈도가 줄어들었고, 균주은행 기탁균주의 경우에도 두 균주 각각 2012년과 2002년 이후로 기탁 건수가 없었다. 최근 양식 넙치에서 우점적으로 분리되는 연쇄구균병의 원인세균은 S. parauberis이다. 또한 육안적 증상 과 병리조직학적 변화를 함께 비교 · 검토하였는데, S. iniae 감염에서는 안구백탁, 출혈, 장염 그 리고 복수저류가, S. parauberis 감염에서는 체색흑화, 심외막염이 주요증상이다. L. garvieae 감 염은 연쇄구균병에서 나타나는 증상이 공통적으로 나타나지만, 독성은 다른 두 종의 증상과 비교하여 약한 것으로 판단되었다. 병리조직학적 증상은 급성인지 만성인지에 따라 내부 장기 별로 변성진행에 차이를 나타내지만 육안적으로 관찰되는 주요증상이 조직학적 소견에 반영 된다.

The purpose of this study is to analyze consumer preference for fish farm HACCP certification using conjoint analysis. This study used raw flatfish product to evaluate the fish farm HACCP. In this study, 500 consumers were surveyed using panel survey and stratified sampling. In the recognition analysis, the farm HACCP certification system was found to be highly recognized by consumers. It can be seen that the brand assets accumulated by existing food and agricultural HACCP certification were transfered to the fish farm HACCP and absorbed. Consumers perceived fish farm HACCP certification as similar one with existing food and agricultural HACCP. Conjoint analysis evaluated three levels factors. The attributes and levels evaluated were : price(25,800 won, 28,400 won, 31,000 won), certification(fish farm HACCP, seafood traceability, and non certified), and origin(domestic, JEJU, and WANDO). The important levels were in order of price(40.8%), certification(30.2%) and origin(29.0%). We found that consumers give higher utility to fish farm HACCP certification compared with non certified and seafood traceability certification. Market simulation results showed that the fish farm HACCP product has 12%p higher market share than non certified products. Seafood traceability certification showed 4.6%p higher market share than non certified products.

The Ministry of Maritime Affairs and Fisheries is supporting the “Environmentally Friendly Fisheries Promotion and Private Assistance Project” to increase production of eco-friendly, high-value-added foods. Private-backed operators selected for the project will have an economic opportunity to build, expand or refurbish eco-friendly fishing grounds. To facilitate this, the scope of project support was expanded after 2015 and an opportunity was prepared for private subsidy projects to grow to a new level in terms of quality and quantity by switching to a public offering project. However, starting in 2017, demand from the private sector will plunge and selected projects will be delayed or the project implementation rate will be lowered. It was a time for subsidy-related laws and systems to be reinforced but private subsidy projects do not temporarily shrink simply due to the increased administrative burden on private subsidy operators on subsidy management. It plans to review the correlation between laws and systems related to the construction of fish farms and suggest ways to enhance the efficiency of implementation so that economic advantages, the biggest advantage of the private subsidy project, can be recovered within the current legal system.

This study is an analysis of the Aquaculture Industry Development Act that has recently been passed by the National Assembly. In order to improve the structural problem of Korea's aquaculture, a large revision of aquaculture related laws and regulations is needed. The enactment of Aquaculture Industry Development Act is necessary to that effect. It is adequate to aim for development as aquaculture industry not as aquaculture, to alleviate entry restriction of aquaculture, and to provision diverse promotion and support policies. However, it is a concern whether the current Aquaculture Industry Development Act can achieve its goal of enhancing the competitiveness of aquaculture and sustainability. Rather than to solve the problem, the act holds the possibility of further fixing or exacerbating the problem. So there is concern for side-effects after the enactment. This is due to the fact that it complicates terminologies by unnecessarily differentiating aquaculture related concepts from the existing Fisheries Act, lacks regulations regarding voluntary participation in aquaculture, and has limited methods to alleviate entry restriction. In addition, there are very few measures for the scale improvement of aquaculture along with the unlikeliness of a significant effect of the review and evaluation for re-licensing. Thus, the Aquaculture Industry Development Act should promptly be revised after its enactment.

In this study, an automatic system for improving the working environment and increasing production efficiency of a laver aquaculture industry in Korea was developed by combining a hydraulic control system and a load cell in a current landing work of the laver. The improved gathering laver system allowed the automatic gathering process of the laver in the sea with the hydraulic control system connected to a cutting machine of the laver on the operating ship, which has been used for gathering the laver semi-automatically in a form of the traditional farming method. The transporting process of the laver from an operating ship to the land was improved as follows. A frame installed on the operating ship and the bag nets were designed and made to hold about 1,000 kg of the laver inside. The bag nets contain the laver on the improved operating ship were tied in knots and hooked on a crane using a load cell. The weight is measured immediately by lifting the bag nets through the load cell system. Weight information is communicated to the fishermen and successful bidders through the application. The advantages of the improved system can help fishermen to fish by improving their working environment and increasing production efficiency. The field survey to improve the landing operation of the laver aquaculture was conducted in Gangjin, Goheung, Shinan, Wando, Jindo, and Haenam in South Jeonnam Province. A total of 10 sites including Gunsan in Jeonbuk Province, Daebu Island in Ansan City, Jebu Island in Hwaseong City in Gyeonggi Province, and Seocheon in Chungnam Province were searched to collect data. Prototypes of the system were tested at the auction house of laver located in Goheung, where laver collection using hydraulic control and landing using road cell could be improved.

최근 양식기법이 보급되어 어가의 양식이 활발해진 감태 (Ecklonia cava Kjellman)는 향후 다양한 품종개발이 예상되고, 이들의 구분을 위한 신품종 심사기준 (특성조사요 령) 작성과 기초자료가 되는 자연 개체군의 변이 폭과 지역적 형태 변이에 관한 연구 필요성은 더욱 커지고 있다. 본 연구는 감태 양식 개체군과 국내 연안 16개소에서 채집한 자연개체군의 형태를 비교하고, 주요 형태 형질의 특성과 변이 폭을 규명하고자 하였다. 감태의 품종 구분에 적합한 형질은 1차엽과 2차엽, 줄기에 대한 주요 형태와 특 징에 관한 14개 측정 형질과 4개 비율 형질, 총 18개 특성을 선정하였다. 군집 분석에서 전체 19개 개체군 중, 자연 개체군인 장길 (E4), 소록 (S7)은 동일 지역 개체군들과 유의한 차이를 보였고, 동해와 남해의 나머지 자연 개체군은 양식 2년생인 수유 (Q6, Q8, Q10)를 포함한 2개 집단으로 구분되었고, 제주의 3개 개체군은 별도의 집단을 이루어 지역적으로 구분되었다. 주성분 분석에서도 군집 분석에서 집단을 이룬 동해와 남해 개체군을 중심으로 양식 개체군은 중앙에 모여 나타났고, 장길 (E4), 소록 (S7)과 제주 개체군들은 주성분 1 (PC1)과 주성분 2 (PC2)에 연관된 2 차엽 지수, 줄기의 길이와 직경, 줄기 길이/1차엽 길이, 1차엽 길이와 너비, 2차엽 수, 2차엽 길이와 너비의 형질에 의해 각 축에 따라 구분되어 나타났다. 이상의 결과로 본 연구에서 조사한 18개 형질은 각 해역에서 유의한 차이를 보이는 개체군 구분을 위한 기준으로 유용성이 확인되었으 며, 감태의 각 지역 개체군은 향후 신품종 개발 후보 종으로 가능성이 클 것으로 기대되었다.

도심형 양식시스템을 바이오플락 양식기술과 아쿠아포 닉스 배양대로 구성하여 사육수를 교체하지 않고 메기를(사육조 3.3톤 2개) 양성한 결과 151일의 사육 후 2.8 g의 종묘가 평균 무게 171.3 g (총중량 56.53 kg)과 235.5 g (총 중량 71.1 kg)로 성장하였다. 입식에서 수확까지의 누적 생존율은 65% 보였고, 성장 구간별로 입식에서 1차 성장 후 분조 이전까지 77.7%, 분조 이후 생존율은 수조에 따라 차이를 보여 각각 92.9%와 78.0%로 나타났다. 초기 바이오플 락 사육수가 만들어지는 과정에서 일부 폐사가 발생하였고, 수질이 안정된 이후에는 폐사가 감소하였다. 메기의 혈액분석결과 사육초기 BFT 사육수가 안정화 이전인 4월에 간 손상 지표인 AST의 농도가 유의적으로 높은 값을 보였으며 ALT, triglyceride는 전 사육기간 내에 차이가 없었 다. Glucose, cholesterol, total protein은 7월에 유의적으로 높은 값을 보이고 다른 기간에는 차이가 없었다. 메기 사육수를 이용한 아쿠아포닉스 가동 시 생산된 식물은 상추, 바질, 적근대, 적치커리 등이 원활한 성장을 보여 5개월간 총 148.85 kg의 식물을 수확하였다. 또한 아쿠아포닉스 시스템에서 식물재배에 따른 사육수 내의 질산 제거능력과, 질산이 제거된 사육수는 메기 사육수로 재사용이 가능한 것으로 확인되었다. 결론적으로, 본 연구에서는 도심형 양식시스템으로 물을 교환하지 않고 어류를 양식할 때 사육 수에 축적된 질산을 제거하고 재사용이 가능한가를 아쿠아포닉스 기술을 결합하여 연구하였으며, 양식생물 (메기) 수용량에 따른 적정 식물량을 유지하면 농수산 복합양식이 가능하다는 것을 보여주었다.

Effective implementation of private subsidy projects requires comprehensive expertise in the aquaculture and construction sectors to be provided to private subsidy operators, local government officials and others involved in budget execution and settlement. Due to the strengthening of laws and systems related to the execution of state subsidies since 2015, the efficient implementation of private-sector grant projects has been difficult for delays in projects, cancellations, and conflicts with local governments from lack of prior awareness and understanding of related regulations. It is expected that the government will be able to activate the project by analyzing the current status and problems of each phase of project implementation for improving quality internalization of the project effects, as well as quantitative growth of the private sector subsidy project for environmentally friendly aquaculture development projects.
