“실치”라 불리우는 베도라치, Enedrias nebulosus 농어목, 장갱이과 베도라치속에 속하는 어류로 우리나라의 서해전역, 일본, 사할린이남, 블라디보스톡 부근 및 북중국에 분포하고 있으며 (Chyung, 1997), 베도라치의 성어는 상업적으로 이용되지 않으나, 치어는 “뱅어포”로서 상품화되어 서해어민의 소득증대에 기여하고 있다 (Hur et al., 1984). 우리나라에서의 베도라치 어획은 주로 안면도를 비롯한 태안반도를 중심으로 4∼6월 사이에 이루어져 (Chyung, 1977) 까나리와 함께 낭장망에 의해 어획되므로 시중에 시판되고 있는 까나리액젓은 순수한 것이라기보다는 상당량 베도라치 액즙이 혼입되어 있다.

In this study, pilot study on the introduction of stationary fishery was performed to solve the problem of fisheries resource reduction. The Fyke net, which is a test fishing net was selected considering the environment, operation and management costs of Ulleungdo, conditions that can be operated by small fishing vessels and personnel. As a result of 11 times survey using Fyke net from April to May 2017, 2,735 individuals and 983.4 kg caught and the dominant species were red seabream, yellowtail, olive flounder, mitra squid, horse mackerel, filefish, etc. In conclusion, if the production of squid, which is one of the major fisheries resources of Ulleungdo, is continuously decreased, it is considered that introduction of small-scale stationary fishery such as Fyke net would be useful as a means replace income of fishermen.

To investigate the feeding habits and trophic level of the blackthroat seaperch, Doederleinia berycoides in the South Sea of Korea, fish samples were collected by a bottom trawl net from fisheries resources survey vessels of NIFS in February, May, August and November 2021. The total length (TL) of these specimens was from 3.3 to 33.1 cm. D. berycoides fed majorly on Teleostei (especially Engraulis japonicus) based on index of relative importance (%IRI=64.4%). D. berycoides underwent an ontogenetic dietary shift. Smaller individuals (<10.0 cm TL) fed mainly on amphipods. The proportion of amphipods decreased as body size increased, whereas the consumption of Teleostei increased gradually. Examination of the feeding habits according to ontogentic feeding patterns in the diets of D. berycoides revealed that the mean weight of prey (mW/ST) continuously increased, while mean number of prey (mN/ST) decreased and then increased. The estimated average trophic level of the D. berycoides was 3.62±0.64, ranging from 3.31±0.52 to 3.79±0.70.

Since the early 20th century, there have been reviews and legislations regarding the legal status of the Government ships operated for non-commercial purposes. In particular, as criticized in the absolute theory of immunity in conventional international law, the sovereign immunity theory has become more vital as a restrictive theory for immunity. As per the customary international law and international law of the sea, non-commercial government vessels, including warships, are provided with sovereign immunity on the sea. National universities of Korea have built and operated training ships and survey ships for educational purposes, such as training high-grade mariners and fishing practices. These training ships sail not only on the national maritime jurisdictions but also on the maritime jurisdictions of other States and the high sea. Therefore, clarifying the legal status of national university training ships is one of the important factors in international navigation according to international law. However, it is not easy to answer the question of the legal status of the training ship. Hence, this article analyzes the parameters that define the Government ship operated for non-commercial purposes and examines whether national university training ships are in line with the relevant criterion. Furthermore, the article analyzes the scope of sovereign immunity in conventional international law and international conventions and identifies the scope of sovereign immunity enjoyed by the national university training ships according to international law.

This study was carried out to clarify the effect of addition of perilla leaf powder (PLP) and carcass grade on the quality and palatability of pork sausage. The chemical composition, pH, calorie, water holding capacity, surface color, textural properties and amino acid composition of the samples were determined, and sensory characteristics were evaluated. Moisture and crude ash were not different among sausage of four type. Crude fat of grade B sausage was higher than that of grade E sausage, and grade B sausage added PLP was higher than grade B sausage without PLP. Crude Protein of grade E sausage was higher than that of grade B sausage. The pH of grade E sausage added PLP was highest, and calorie of grade B sausage without PLP was highest among sausage of four type. Water holding capacity of grade B added and free PLP was significantly higher than grade I sausage. The residual nitrite of sausage added PLP was significantly lower than sausage without PLP. In case of Hunter's $L^{*}$, grade B sausage and free PLP sausage were significantly higher than grade E sausage and sausage added PLP, respectively. In case of Hunter' $a^{*}$, grade E sausage and free PLP sausage were significantly higher than grade B sausage and sausage added PLP. Hunter's $b^{*}$ of sausage added PLP was higher than that of free PLP sausage. Textural properties, hardness, springiness, cohesiveness and chewiness were significantly different among sausage of four type, but gumminess of grade E added PLP was lowest among sausage of four type. Total amino acid was not significantly different among sausage of four type. Sensory color and texture of grade B sausage were superior to grade I sausage, palatability of free PLP sausage was superior.sage was superior.

The expression of signal to noise ratio (SNR) is derived for the individual echo sounder and for the general specifications of commercial echo sounder. The SNR is depicted by several factors on transmitting and receiving, sound propagation, scattering by fishes, and mainly self ship noise. The detection ranges of echo sounders in depth and breadth are derived by finding the border of an acceptable SNR. The detection ranges are computed for the echo sounders of individual and general specifications. Generally, the detection range is lager for low frequencies. Increasing an electrical power and a diameter of transducer is not as effective for high frequencies as for low frequencies to increase the detection range. The theoretical results of the detection range can be applied to design low electrical power echo sounder for coastal use, to select an appropriate echo sounder, to know the capability of a sounder, and to interpret echograms. A method for evaluating and designing low electrical power echo sounder is developed. A universal diagram for the basic design of the low electrical power echo sounder where SNR is plotted against frequency is developed. An appropriate frequency, transducer diameter, and beam width are easily determined by using the diagram.

The Japanese Flying Squid (Todarodes pacificus) is a commercially important species in South Korea and the most popular species among consumers. However commercial catches of Japanese Flying Squid have been declining since 2000. In this study, we conducted a stock assessment to identify stock status. This study differed from previous studies in two aspects: a greater amount of available fishing effort data was used, and data from China, Japan, and Korea were included. A CMSY (catch-maximum sustainable yield) model was used to estimate MSY, biomass and exploitation with Bayesian state-space implementation of the Schaefer (BSS) model for the method of stock assessment, and evaluated the species by dividing into two groups, 'Korea' and ' Korea·China·Japan'. In all cases, Japanese flying squid biomass showed a general decreasing trend. Additionally, the biomass estimated for 2020 was lower than the biomass necessary to achieve the maximum sustainable yield. To manage Japanese Flying Squid effectively, it is necessary to strengthen the resource management strategies of individual countries and prepare a cooperative plan among countries.

담낭용종의 잘 알려진 위험요소는 대사증후군, 연령, 이상지질혈증 등이다. 제주도는 한반도에서 가장 큰 섬으로 한국의 본토에서 약 80km 떨어져 있으며 행정구역상 제주시와 서귀포시로 나뉘어 있지만 기업들과 편의시설들, 학교들 때문에 자연스럽게 시내와 시외로 더 나누어진다. 많은 이주민들과 젊은 성인들은 상업 활동이 활발한 시내 지역에 사는 경향이 있다. 고령 성인들은 어업이나 농업에 종사하기 때문에 시외 지역에 사는 경향이 있다. 고령의 성인들은 전통적인 식이를 유지하고 있고, 그들 중 다수는 힘든 노동으로 인해서 고위험 알코올 음주자의 비율이 높다. 이러한 요인들로 인해 두 지역간의 담낭용종 유병률에도 차이가 있을 것이다. 따라서 이 연구의 목적은 제주도 두 지역간에 담낭용종의 유병률을 알아보고 그 유병률과 관련된 다양한 요인들을 비교해 보고자 하는 것이다. 이 연구는 2009년 1월부터 2019년 12월까지 제주대학교병원 단일 건강검진센터에서 건강검진을 시행한 21,734명을 대상으로 하였다. 시내 지역과 시외 지역 거주민들의 담낭용종 유병률은 각각 10.1%와 8,7% (P = 0.006)로 의미있게 차이가 있었다. 평균 총콜레스테롤 수치가 시내 지역 거주민들에서 시외 지역 거주민들보다 높았고, 음주와 관련된 평균 알카라인 인산분해효소와 감마-글루타밀전이효소 수치들과 평균연령은 시외 지역 거주민들이 시내 지역 거주민들보다 더 높았다. 나이, 알코올 섭취와 평균 콜레스테롤 수치가 이러한 두 지역 간에 담낭용종 유병률의 차이를 만들었을 것이다.
