  • Catch characteristics according to the tide and fishing time were analyzed through the fishing log data of trawls which work at Arafura Sea of Indonesia. This study aimed to provide basic data to make a fishing plan from the catch difference according to fishing time after analyzing the suitable fishing time of fish species. The results obtained are summarized as follows ; 1. Catches were the largest at the day of very weak tide as 22.8% of total catch and was the smallest at the day of a little strong tide as 16.9% of total catch. 2 Catches of croaker Argyrosomus sp. & Johnius vogleri, silver hairtail Trichiurus lepturs and coachwhip ray Himantura sp. were the largest at the day of weak tide(20.8%), very weak tide(33.8%), a little strong tide(22.0%) and catch for croaker and silver hairtail were the smallest at the day of a little strong tide(18.7%-10.0%) and coachwhip ray was the smallest at the day of strong tide(16.8%). 3. Catches were the largest at the time of 08:00-12:00 as 19.7% of the total catch and were the smallest at the time of 20:00-24:00 as 14.1% of total catch. 4. Catches of croaker, silver hairtail and coachwhip ray were the largest at the time of 00:00- 04:00(21.0%), 08:00-12:00(35.0%) and 12:00-16:00 (21.2%) and were the smallest at the time of 12:00-16:00(12.7%), 20:00- 24:00(4.6%) and 20:00-24:00(13.4%).

  • Effects of four kinds of phosphate complex on the water holding capacity(W.H.C) and protein solubility of yellow-corvenia(Pseudosciance manchurica) and hair tail(Trichurus lepturns) meat paste were investigated. The formulations of four kinds of phosphate complex employed to this experiment were made by mixing several phosphates such as sodium polyphosphate, sodium pyro-phosphate, sodium acid pyro-phosphate, potassium pyro-phosphate, sodium tetra meta-phosphate, sodium ultra meta-phosphate and sodium hexa meta-phosphate, and monoglyceride at different mixture ratios. Among the four kinds of phosphate complex, phosphate B complex which was formulated by mixing sodium poly-phosphate 50%, sodium pyro-phosphate 20%, sodium tetra meta-phosphate 20%, sodium acid pyrophosphate 5% and sodium ultra meta-phosphate 5% was most effective on enhancing the W.H.C and protein solubility of yellow corvenia meat paste, and in case of hair tail meat paste, phosphate C complex which was formulated by mixing sodium poly-phosphate 40%, sodium pyro-phosphate 30%, potassium pyro-phosphate 15%, sodium tetra meta-phosphate 10%, and sodium hexa meta-phosphate 5% was more effective than other phosphate complex, and their optimum addition level was 0.4% respectively in weight of fish meat paste. Texture characteristics such as hardness, cohesiveness, and springiness value of Kamaboko(fish meat paste product) were evaluated as best when 0.3% of phosphate B complex was added. The optimum cooking condition of Kamaboko to get good texture was heating for 45 minutes at 85$^{\circ}C$.

  • 생물의 특성 중 하나는 외부나 내부의 자극에 대하여 반응한다는 것이다. 이러한 환경의 변화를 감각기관에서 수용하여 그 환경의 변화에 적절하게 대응하는데 이러한 반응은 작게는 운동, 크게는 행동이라는 형태로 나타난다. 동물에 있어서 이와 같이 자극에 대하여 특이한 반응행동을 일으키는 성질들을 주성(Taxis)이라 한다. 주성에는 자극에 따라 주광성, 주촉성, 주류성, 주온성 등이 있으나 어업에 있어서 가장 광범위하게 이용하고 있는 것이 어류의 주광성이라 할 수 있다. (중략)

  • 근해 안강망 어업은 강한 조류를 이용하는 어법으로서 조차가 큰 황해∼동중국해에서 주로 조업이 이루어진다. 특히, 갈치, 조기류, 병어류, 아귀류, 새우류, 두족류 등의 중ㆍ저층에 서식하는 유영생물을 대상으로, 이들 어종을 찾아 이동하며 조업을 하는 특성을 가지고 있다. 근해 안강망 어업은 90톤급 어선이 인천, 군산, 목포, 여수 등지에서 총 650여 척이 허가되어 있는데 이중 80% 정도가 실제 조업을 하고 있다. 이중 군산에 근거를 두고 있는 근해 안강망어업은 90척 내외로 황해∼동중국해를 어장으로 이용하고 있다.(안강망 수협, 미발표자료).

  • 근해안강망어업에서 주로 어획되는 수산자원은 참조기, 갈치, 아귀등의 저서성어류로서, 겨울에는 월동장인 우리나라 서해남부 및 동중국해 북부해역으로 남하회유하고 봄이 되면 황해 및 중국 연안의 산란장으로 북상이동하는 계절회유를 한다. 따라서 근해안강망어업의 주간어황은 황해 및 동중국해에 서식하는 대상어업자원의 자원량변동의 영향을 받으며, 해황의 변동에 따른 회유경로의 경년변동 및 계절회유에 의한 주 서식처의 변동, 조석의 변동, 어장의 일기등의 영향을 받는다. (중략)

  • Short-term forecasting of fish catch is of practical importance in fisheries management. Ecosystem models and multi-species models as well as traditional single-species models fall short of predicting power needed for practical management of fisheries resources due to the lack of sufficient data or information for the required parameters. Univariate time series analysis, on the other hand, extracts the information on the stochastic variability from the time series itself and makes estimates of the future stochastic variability. Therefore, it can be used for short-term forecasting with minimum data requirements. ARIMA time series modeling has been applied to the monthly Korean catches of hairtail (Trichiurus lepturus) for $1971{\sim}1988$. Forecasts of hairtail catch were made and compared with the actual catch data from $1989{\sim}1990$ which were not included in the parameter estimation. The results showed a good agreement (r=0.938) between the forecasts and the actual catches with a mean rotative error of $59.5\%$

  • The feeding habits of john dory, $Zeus$ $faber$, were studied using 462 specimens collected in the coastal waters of Geomun-do, Korea. The size of the specimens ranged from 7.8 to 40.2cm in standard length (SL). $Z.$ $faber$ was a piscivore that consumes mainly teleosts such as $Trichiurus$ $lepturus$, $Scomber$ $japonicus$, $Callanthias$ $japonicus$ and $Trachurus$ $japonicus$. Of the fish species $T.$ $lepturus$ was the most preferred prey. Its diet also includes cephalopods, shrimps and euphausia. Smaller individuals (<15 cm SL) fed mainly on fishes and cephalopods. The proportion of cephalopods decreased as body size increased, whereas the consumption of fishes gradually increased. Fishes accounted for almost stomach contents of larger individuals (more than 15 cm SL).

  • The purpose of this study is to predict multiplication patterns of foodborne pathogens according to packaging methods and storage conditions in home-delivered meals. Pan fried oak mushroom and meat, soy sauce glazed hair tail and roasted dodok which inoculated $10^6\;CFU/g$ of foodborne pathogens were packaged by wrap packaging, top sealing, vacuum packaging and stored at 25, 4 and $-18^{\circ}C$ during 5 days. The result of study was revealed that the growth and multiplication pattern of the inoculated foodborne pathogens was inhibited in chilling and freezing storage after vacuum packaging, and was significantly influenced by storage temperature. The survival of Listeria monocytogenes was also significantly influenced by storage period. The effective method to preserve the bacteriologic safety of pan fried oak mushroom and meat and soy sauce glazed hair tail in home-delivered meals was stored for maximum three days in chilling storage after vacuum packaging.
