Physiological studies on the salinity tolerance with respect to survival rate and body composition changes of the abalone Haliotis discus hannai were conducted by rapidly changing the salinity in an indoor rearing system. The survival rate of the control (35 psu), 30 and 25 psu groups at $15^{\circ}C$ was 100%. The survival rate of the 20 psu group was $35{\pm}5.0%$. Survival rate of the 15 psu group was 0%. At $15^{\circ}C$ and 35, 30, 25, 20, 15 psu, the moisture contents of abalone muscle were $82.1{\pm}0.7$, $82.5{\pm}0.7$, $84.9{\pm}0.5$, $86.9{\pm}0.3$ and $86.6{\pm}0.4%$, respectively. Crude lipid contents were $0.47{\pm}0.03$, $0.47{\pm}0.03$, $0.47{\pm}0.09$, $0.77{\pm}0.09$ and $0.63{\pm}0.03%$, respectively and crude ash contents were $1.30{\pm}0.12$, $1.33{\pm}0.15$, $1.13{\pm}0.23$, $1.87{\pm}0.15$ and $1.40{\pm}0.31%$, respectively. At salinity below 20 psu, these values increased compared with the control. The general components of abalone muscles significantly increased below 20 psu, while amino acid composition showed no significant difference with salinity and water temperature.

Two new species of Leptochelia Dana, 1849 are described from the western coast of Korea. Leptochelia grandidentata n. sp. is similar to L. itoi and L. lusei characterized by pleonites 4 and 5 of subequal lengths and a uropod endopod with 4 articles but differentiated by a cheliped fixed finger longer than the dactylus and with 4 teeth along the incisive margin, a maxilliped basis with 4 distal setae, and pereopod 1 propodus that is much longer than the combined length of unguis and dactylus. Leptochelia suhi n. sp. shares some features of L. myora with the first article of the uropod endopod longer than the second article and a maxilliped endite with 3 spiniform distal setae but can be differentiated by the cephalothorax being longer than the pleon, the relatively longer antennule article 3 compared to article 2, and the cheliped fixed finger with 3 robust teeth along the incisive margin. In this study, full descriptions of L. grandidentata and L. suhi are given, and a comparison with closely related species belonging to the ‘dubia/savignyi group’ is tabulated and discussed.

It is provided that seafarers qualified in accordance with STCW(International Convention on Standards of Training Certification and Watch-keeping for Seafarers) convention and code in safety training shall be required, every five years, to provide evidence of having maintained the required standard of competence, to undertake the tasks, duties and responsibilities listed in Chapter VI, section A-VI/1 of the STCW Code A. Every party to the STCW Convention has amended the relevant national regulations according to the above international convention and code. These amended Seaman's Act require the updating safety training which is only five years valid for existing seafarers serving onboard ship on international voyage. And above specified existing seafarers must, as of the 1st January 2017, have documentary evidence of either having completed the training course or updated their training within the last 5 years. In relation to the above international trend, the Korean Ministry of Oceans and Fisheries also has completed an amendment to its Seaman's Act. But, the Korean Seaman's Act has a supplementary provision to exempt the seafarers who have completed STCW advanced safety training from basic safety training. The purpose of this study is to define the problems of above mentioned exemption provisions and to make better policies for improvement. In order to complete the purpose, the research team has conducted an in-depth survey of various foreign cases on STCW safety training. Moreover, the team has suggested an improvement scheme in consonance with Korean shipping industry and society through out this report.

As discarded fishing gear settles or floats on the seabed, it destroys the spawning and habitat of fisheries resources that causes various safety accidents and adverse effects on the environment, such as generating microplastics and causing ship accidents. In order to solve this problem, this study is intended to present an implementation plan for establishing a fishing gear deposit system in order to use it as basic data for establishing policies for fishing gear management in Korea. In order to successfully implement the fishing gear deposit system, the deposit system must be established in the form of fishing gear completed at the production stage. It was found that the marking of the object should be easy, and that determining an appropriate deposit amount to motivate the return of waste fishing gear and establishing a convenient return procedure for returned waste fishing gear were important factors. In addition, transparent management of unreturned deposits and mandatory use of fishing gear subject to the deposit system for fishermen will be necessary. The role of a specialized organization to manage and operate all of these procedures is also very important. It is necessary to establish a new mandatory provision in the Fisheries Act to require fishermen who directly use fishing gear to use fishing gear with a deposit refund mark, and to ensure the implementation of the deposit system by linking it with the evaluation items of government policy projects. Since the main purpose of the deposit system is to collect discarded fishing gear, a support plan will be necessary in accordance with the purchase project for fishing waste salvaged by local governments in 2020.

The questionnaire survey was carried out to collect basic data to identify the cause of the risk that did not appear in the current data provided by the fishermen's occupational accidents of the National Federation of Fisheries Cooperative (NFFC) to the onsite specialist, such as a fishing master, chief engineer and fisher in stow net fishing vessel from June to July 2018. The results are as follows. A total of 134 cases were surveyed, including 53 cases in Yeosu, 44 cases in Mokpo, 30 cases in Boryeong and 7 cases in Gunsan. Approximately 60% of the respondents on board the stow net fishing vessel were more than 20 years old, and the boarding experience was seasoned and suitable for the respondents. In the 4M analysis by safety accident factor during fishing work, the mechanical factors included 51 cases (25.0%) of decrepit equipment or poor maintenance and 49 cases (24.0%) of systemic error of fishing equipment. The environmental factors exhibited 71 cases (33.5%) of poor communication by mixed manning of foreign fishermen and 63 cases (29.7%) of poor environment such as heavy weather etc. The human factors showed 78 cases (37.3%) of personnel's carelessness and 45 cases (21.5%) of unskillfulness of operating net and haulers. The management factors exhibited 59 cases (32.1%) of work practice of poor safety precautions and 56 cases (30.4%) of inadequacy of education on hazard factor. The results are expected to contribute to the creation of a safe operating environment for stow net fishery, such as a fisher boarding a stow net fishing vessel, enabling the analysis of major causes of working safety accidents by cause.

Stow net fishery is one of the fishery with high fishing work accidents in southwestern sea of Korea. We conducted to serve as basic data for improving the healthy and safe working environment of fisher using risk assessment process (ISO45001) with fishermen's occupational accidents of the National Federation of Fisheries Cooperative (NFFC) from 2016 to 2018. The average occurrence rate of victim in this fishery was 9.04%, 16.7 times more than such rate in all industries. In addition, the average fatality rate was found to have a very serious level management to 31.06‱, 27.7 times more than such rate in all industries. The safety hazards of stow net fishery was more likely to occur by other general industrial groups, with more severe consequences after the accident. According to 4M analysis, 58.6% of all accidents were caused by human factors, 24.0% by environmental factors, 16.0% by mechanical factors, and 1.5% by managerial factors, respectively. The occurrence frequency by accident type was the highest in 187 cases (32.2%) for struck by object, 158 cases (27.2%) for slipping, and 94 cases (16.2%) for being in contact with machinery. Severity is the highest for others such as diseases etc., in the order of being struck by object, being in contact with machinery, falling from above slipping, collapsing, bumping, and burning. Being struck by object, being in contact with machinery, and slipping are high-risk groups, falling from above others, bumping, and burning are medium-risk groups based on the risk assessment using the occurrence frequency and severity of accident. The obtained results are expected to contribute to the safe operation environment subsidy for fishing crews on the stow net fishing vessel.

부산항내는 시간당 10척 이상의 선박이 통항하고 있고, 일본 왕복 제트포일 여객선이 30 kts~40 kts의 고속으로 항행하고 있어 우리나라에서도 고밀도 교통해역으로 간주된다. 더불어 이 항로 내에서는 제트포일 선박의 약 18 %가 고속으로 추월을 하거나 항로 밖으로 이탈하여 운항하고 있어 타 선박과 빈번히 조우하거나 항로 밖 항행 등과 같은 현행 법령을 미준수하고 있는 것으로 10일간의 해상교통조사를 통하여 분석되었다. 이 논문에서는 부산항의 교통조사 결과를 기반으로 한 해상교통류 시뮬레이션을 통하여 부산항내의 제트포일 여객선의 운항자 허용 가능 속력이 약32노트 이하로 계산되었으며, 제트포일 선박이 항로 내 및 항로 밖으로 통항하는 경우의 조선부담감 발생비율 차이가 미미한 것으로 분석되었다. 또한 시간당 통항척수가 감소함으로써 조선부담감이 다수 감소하기 때문에 피크타임 시간대 운항을 피하여 통항안전을 확보하여야 할 것이다.

The adjudication of Korean Maritime Safety Tribunal (KMST) was analyzed to collect basic data to identify the cause of the risk that did not appear in the current data provided by the fishermen's occupational accidents of the National Federation of Fisheries Cooperative (NFFC) in stow net fishing vessel from 2015 to 2019. The personnel's carelessness was the most common in 29 out of 33 accidents (87.9%), followed by 25 cases (75.8%) of inadequacy of instructions, 24 cases (72.7%) of inadequacy of education on hazard factor, 20 cases (60.6%) of no personal protection equipment, 18 cases (54.5%) of poor guard, 17 cases (51.5%) of inadequacy of work method, 16 cases (48.5%) of absence of emergency stop button, 14 cases (42.4%) of work practice of poor safety precautions that affected more than 40% of all accidents as accident causes. These causes had a strong influence on each other, and the ratio of accident causes is high. With this relationship, accidents can be prevented or the severity of human injury can be reduced if types of accident process can be estimated with a scenario, and the key points before the accident in the scenario are switched to safe points.
