The basic investigation of the sea eel pots fisheries by questionnarie observation and dimension of the pots by fishing operation were carried out in order to develop for mechanical hauling system with 20~50 gross tonnage fishing boats from June to December, 1988. Number and weight of fish per pot between smaller diameter 11cm and larger 13cm of the pot have no significance so that the drag of the smaller pots can be decreased about 20% than the larger pots. The operating time by two men from opening to closing with screwing lock entrance was slightly faster than that by three men with knotting entrance even though the losses with two kinds of entrances while fishing operation were about the same. It was very reasonable that stone and lead sinker on the main line were substitute for two or three lead core P.P rope to make it smooth surface of the main line for mechanization of the continuous fishing operation.

최근 우리나라 연안어업은 한일, 한중어업협정, WTO 가입 등으로 주변 환경이 급격하게 변화되는 한편, 연근해 어자원의 감소와 근해어업과의 경쟁조업 등으로 인해 경영수지가 극도로 악화되고 있다. 이로 인해 연안어민들의 최소 생계기반 마저 위협받고 있는 실정이다. 이에 본 연구는 연안어업의 수익향상과 자원관리 측면에서 경제성 연안 어선의 선형개발 방안을 검토하였다. 이를 위해 새로운 어선어업 환경에서 요구하는 자원관리, 채산성보장 등의 경제 사회적 요건을 기술적 요소로 변환하여 다목적어선의 개념을 설정하고 관련 기초자료를 마련하였다. 특히, 연안어업을 동해, 서해, 남해, 서남해 등으로 나누어 허가업종의 실태와 어민 요구사항이 서로 다른 점을 감안하여 다목적화 가능 업종을 선정하고, 선형개발 방안을 도출, 정리하였다.

The Ministry of Maritime Affairs ＆ Fisheries have plaining the advancing fishery information integrated system for the fishing present condition, marine resource administration and applicability considering. The fishery information communication system is build up to the raw data ＆ process-network-content. The communication system must be small size, low cost and adapted SSB transceiver, that is using fishery shipping. In this paper We present digital data communication network to exchange information for fishery and safety between fishing ship and coast station in cheeper communication fee using SSB in HF band.

The purpose of this study is to enhance the cultural heritage value of the Juk-Bang-Ryeum (Bamboo Weir) and prove the originality through the review of historical literature. The main industry of Korean was agriculture and fishery from ancient. In the ancient, fishery instruments are not enough due to the lack of fishing technology. The Juk-Bang-Ryeum was considered as important national resources and asset. It give us many implications about the wisdom of our ancestors because of it's scientific principle of the structure. It is surely a cultural heritage to preserve in the future because it is considered as important community asset as well as more natural and environment oriented fishing method. In the literature, the origin of 'Juk-Bang-Ryeum' can be found as 'Eo-Ryang' or 'Bang-Ryeum'. The records on this terminology go back to the Corea Dynasty, but their documentary records are rare, and most of them are records of the Chosun Dynasty. In this study, we surveyed mainly the literature records about the southern coast region in the period of Chosun Dynasty. This study contributes for preserving the cultural assets of our ancestors who pursued eco-friendly fishery method, and it is also of great significance to produce objective data based on records for the registration of the World Record Heritage.

It's about time we had to think an alternative to recover out insufficient fishery market caused by IMF locally as well as the fishery agreement on Japan and China. The Ministry of Maritime Affairs ＆ Fisheries have planning the advancing fishery information integrated system for the fishing present condition, marine resource administration and applicability consideration. The fishery information communication system is build up to the raw data ＆ process-network-content. The communication system must be small size, low cost and adapted SSB transceiver, that is using fishery shipping. In this paper We present digital data communication network to exchange information for fishery and safety between fishing ship and coast station in cheeper communication fee using SSB(single Side Band) in HF(High Frequency) band.

멸치, Engraulis japonica는 우리나라 주변해역에 널리 분포하는 소형의 표층성 부어로서 특히 국내 남해에 있어서는 상업적으로 중요한 어획대상종이 되고 있다(장등, 1980). 또한 멸치는 자치어기부터 성어에 이르는 단계까지 어식성 어류들의 주요한 먹이원이 되고 있는데 이는 소형의 플랑크들을 주로 섭이하고 있는 멸치가 해양의 저차생산력을 이용가능한 자원으로 변환시키는 역할을 담당하는 등 천연의 먹이생태계에 있어서도 중대한 위치를 차지하고 있는 어종이라 볼 수 있다(화전, 1997). (중략)

우리나라의 서남해안에 서식하는 조피볼락(Sebastes schlegeli) 은 계절성 번식을 하해산어로서 동물성 단백질 공급원으로서 국민 식생활에 중대한 역할을 하고 있는 고급어종인 조피볼락의 우량종묘 생산 및 보급을 위하여 번식효율의 개선과 동시에 우수 개체를 친어로 선발 및 교배시키는 것이 무엇보다도 시급한 과제라 할 수 있다. 계절, 수온, 광주기, 광도, 서식처, 사료, 경쟁관계, 성별, 성숙단계, 수질 등의 생물 및 물리화학적 인자의 차이에 의해서 해산어의 형태적인 변이와 단백질 다형성이 나타나게 된다(Saunders and McKenzie, 1971; Somero and Soule, 1974; ), (중략)

넙치(Paralichthys olivaceus)는 1980년대 초부터 일본으로부터 수정란을 도입하여 양식되기 시작하였으며, 현재 전 연안에서 종묘생산 또는 양식이 이루어지고 있다. 그러나 최근 연안어장의 오염과 질병의 발생으로 인해 넙치 양식 생산성이 크게 낮아지고 있다. 또한 장기간 동일계통의 넙치를 친어로 이용함으로서 유전적 열성화로 인한 많은 문제점이 나타나고 있는 실정이다. (중략)

최근 연근해 어선에서는 소형 레이더 장치를 항해 및 어로장치와 함께 탑재하고 있으나, 소형 레이더에 있어서는 타선의 진운동정보(진침로, 진속력)나 충돌회피정보(CPA, TCPA), 또한, 주위의 상황변화에 대한 다양한 물표정보(진운동벡터표시, 실시간 추적정보)를 제공할 수 없는 문제가 있다. (중략)
