  • Chub and blue mackerels are popular fish resources in Korea, but little is known about each biochemical characters of different anatomical regions. To investigate biochemical characters of chub and blue mackerels, three ordinary muscle regions were identified by their fin position; namely anterior, median, posterior. In addition, red muscle, as a dark muscle, was obtained from beneath the lateral line to compare with ordinary muscles. Proximate and lipid-class compositions did not show any discernible trends in the different anatomical ordinary muscles from mackerel of the same kind, while significant differences between ordinary and red muscles in the same mackerel, or between chub and blue mackerels, were observed. Red muscles from both mackerels had higher levels in lipids with higher neutral lipid class compared with ordinary muscles. The major difference between chub and blue mackerels was the levels of lipids and neural lipid class, indicating that all muscles from chub mackerel showed higher levels of neural lipids compared with those of blue mackerel (P<0.05). Fatty acid compositions showed that the percentage of polyunsaturated fatty acids (PUFA), especially docosahexaenoic acid (DHA, 22:6n-3), in median and posterior was higher compared with anterior muscle from both mackerels. When compared with chub mackerel, blue mackerel showed higher percentage of DHA in all muscle regions. In amino acid analysis, taurine concentration was much higher in the red muscle than in the ordinary muscles. But levels of histamine, glutamic acid, leucine and lysine were higher in the ordinary muscles. Our results indicated that chub mackerel contained more lipids than blue mackerel and that red muscle had higher levels of neural lipid and taurine compared to ordinary muscles.

  • In order to develop the substitutive materials for natural baits of swimming crab pots, the fluorescent characteristics of the baits were analyzed, and the preference of fluorescent dyes were investigated by the mean entrapped catch number to the pots through the water tank experiments and fishing experiments. On the investigation of fluorescent characteristics by the 5 kinds of baits, mackerel, krill, manila clam, pig's fat and chicken's head which were used in substitutive baits for test in the UV long wave(365nm) area, it showed clear blue fluorescence in the skin of mackerel, shell of krill, manila clam and bill of chicken's head, and green fluorescence in the mackerel s muscle and internals, and yellow fluorescence in the pig's fat and chicken's head. On the investigation of fluorescent characteristics by the bait cages in the UV short wave(254nm) and long wave(365nm) area, it showed each green, red and blue fluorescence in the cylinderical or hexahedral red plastic bait cages which were painted each green, red and blue fluorescence dyes, but it showed yellowish green flourescence in the cylinderical or hexahedral red plastic bait cage which was painted yellow fluorescent dye. On the preference investigation of the fluorescent dyes of swimming crabs by the 5 kinds of the bait cages which were put the mackerel in the non-fluorescent red plastic cage($RF_N$), red, yellow, green and blue fluorescent plastic cages(RF, YF, GF, BF) each, nonfluorescent red plastic cage($RF_N$) was entrapped mean 2.0(6.7%), but blue fluorescent plastic cage(BF) was mean 5.0(16.7%) and it was more 2.5 times comparing to $RF_N$, and red fluorescent cage(RF) was same level and green fluorescent cage(GF) was 50% of catch number comparing to $RF_N$, and yellow fluorescent cage(YF) was entrapped nothing(F 46.324, P < 0.05). On the investigation of the entrapped catch number to the pots which were put the mackerel in the blue fluorescent hexahedral plastic cage(HP) and blue fluorescent silicon mackerel model cage(SM), HP was mean 3.4(11.3%) and it was a little more comparing to SM which was entrapped mean 3.2(10.7%)(t 0.775, P > 0.05). Fishing experiments on the preference investigation of swimming crabs by the pots which were put in the non-fluorescent red plastic cage($RF_N$) and blue fluorescent plastic cage(BF) were conducted 3 times. Mean catching number and weight of $RF_N$ were 71.7 ind.(18.3%) and 16.9kg(64.3%), and those of BF were 93.0 ind.(23.1%) and 19.8kg(64.5%), respectively.

  • We developed a time-temperature indicator (TTI) that rapidly determines whether frozen mackerel Scomber japonicus has thawed during its distribution. Our TTI was made from filter paper capable of absorbing mackerel exudate that was soaked in a 20% citric acid solution at pH 4.0 and then dried. The dried absorbent paper was cut and attached to blue litmus paper with a 2 mm overhang. The fixed litmus paper was covered with a polypropylene film and sealed. The indicator was placed inside a polyvinyl vacuum package containing the mackerel sample. The vacuum-sealed packaged was frozen at $-20^{\circ}C$ for 24 h. After freezing, the color change and time dependence of the indicator were observed at room temperature ($25^{\circ}C$) and demonstrated the utility of this TTI for rapidly determining whether frozen mackerel underwent thawing during distribution.

  • The aims of this study are to access the status and problems and draft possible solutions of Korean trawl fishery in New Zealand sea. The main target fish species for Korean trawlers in this sea were barracouta, blue mackerel, hake, hoki, jack mackerel, ling, oreo, orange roughy, southern blue whiting, spiny dogfish, squid and silver warehou. The Korean trawl fishery are suffering from a supply of seaman, continuous increasing coast of the counter partner, repair of vessel and seaman supply. It may be useful for getting over these difficulties to build a new trawler with a automatic operation system.

  • 기존에 생선 검출을 위한 ELISA 개발은 여러 편 보고된 바 있으나, 고등어만을 특이적으로 검출하는 방법에 관한 보고는 거의 없었다. 본 연구에서는 고등어 parvalbumin에 대한 토끼 항체를 이용하여 가공식품 중 고등어의 검출을 위한 ELISA를 개발 하였다. 암모늄침전법과 Sephadex G-50 column chromatography를 이용하여 열에 안정한 12 kDa의 고등어 parvalbumin을 분리, 정제하였다. 여기에서 얻어진 parvalbumin을 토끼에게 면역하여 생산한 항 parvalbumin 항체 및 특이항체-HRP 복합물을 이용하여 샌드위치 ELISA(sELISA)의 조건을 확립하였다. 이때 parvalbumin 의 검출한계는 3 ng/mL이고, 고등어(생살)의 검출범위는 5-5,000 ${mu}g/mL$이었다. 이어서. 광어, 우럭, 오징어, 꽃게, 꽁치, 대구, 새우, 연어, 바다가재, 고등어에 대한 교차반응을 조사한 결과 고등어에 대한 반응성은 월등히 높았으나 다른 수산식품에서는 반응성이 거의 없거나 매우 낮게 나타나 고등어에 대한 특이성이 매우 높은 항체임을 알 수 있었다. 또한 분석시 시료의 열 안정성은 $100^{\circ}C$까지 양호하였으며 크림스프, 이유식, 소시지, 소스에 대한 spike test(0.01-0.3%)에서 분석회수율은 각각 104, 101, 54, 0%로 나타났다. sELISA에 의하여 16점의 시판시료 중 고등어의 함유 유무를 조사한 결과, 정성적으로 표시와 일치하는 것은 75%이었다. 그러므로 본 연구에서 개발한 sELISA는 일부 한계가 있기는 하지만, 가공식품 중 고등어를 정성적으로 검출하는데는 효과적으로 활용할 수 있을 것이다.

  • In order to develop the substitutive materials for natural baits of swimming crab pots, the attracting effects of swimming crab such as the preference of baits which were made of the by-products of marine and stock raising through the water tank experiments and fishing experiments. On the investigation of mean entrapped catch number to the pot by the baits after putting the 4 kinds of baits, mackerel(M), mackerel with grinded mackerel s internals($MM_I$), mackerel with tuna s internals$MM_I$) and makerel with grinded krill(MK) each in one pot by turns, $MM_I$ and MK were entrapped mean 3.9(13.0%) and they were a little more comparing to M, and $MT_I$ is least with mean 2.1(7.0%)(F=12.913, P < 0.05). Otherwise, on the preference investigation of swimming crabs by the baits after putting the 4 kinds of baits in the 4 pots each, M was entrapped mean 3.0(10%), but $MM_I$, $MT_I$ and MK were mean 1.2(4.0%), 1.0(3.3%) and 1.5(5.0%) each and they were only 30-50% of M(F=13.398, P < 0.05). On the preference investigation of swimming crabs by the 5 kinds of baits, mackerel(M), and krill(K), manila clam($M_C$), pig s fat($P_F$) and chicken s head($C_H$) which were used in substitutive baits, M was entrapped mean 3.2(10.7%), but K was about 50% of catch of M with mean 1.6(5.3%), and $M_C$, $P_F$ and $C_H$ were very few with mean 0.1-0.2(0.3-0.7%)(F=89.186, P < 0.05). On the preference investigation of swimming crabs by the pots which were put each the 3 kinds of baits, original krill(K), grinded krill with gluten and soybean oil cake($K_GGS$) and grinded krill with gluten, soybean oil cake and glycine($K_GGSG_L$) in the blue fluorescent hexahedral plastic bait cages(BF), and which were put the mackerel(M) in the non-fluorescent hexahedral red plastic bait cage($RF_N$), it was entrapped mean 3.0(10.0%) in the pot which was put the mackerel in the $RF_N$, and the same level in the pots which were put the K and $K_GGSG_L$ in the BF, but it was mean 2.0(6.7%) in the pots which was put the $K_GGS$ in BF and it was decreased by 30% of catch comparing to $RF_N$(F=3.750, P < 0.05). On the preference investigation of swimming crab by the pots which was put grinded tuna with gluten, soybean oil cake and glycine($T_IGSG_L$) in the blue fluorescent hexahedral plastic bait cage(BF), and which was put mackerel(M) in the nonfluorescent hexahedral red plastic bait cage($RF_N$), it was entrapped mean 3.3(11.0%) in the pot which was put mackerel in $RF_N$, and mean 2.7(9.0%) in the pot which was put $T_IGSG_L$ in BF and it was about 15% less comparing to use bait M(t=1.387, P < 0.05). As a results of fishing experiments, a plan for enhancing catching efficiency of $T_IGSG_L$ will be required because catching efficiency of $T_IGSG_L$, alternative bait, was half of fish catching efficiency of natural bait using mackerel. Fishing experiments were conducted 3 times using reinforced substitutive artificial bait that is reinforced attractive effect of $T_IGSG_L$ and composed of tuna intestine, grinded mackerel, gluten, soybean cake, glycine and alanine($T_IM_GGSG_LA$). Catching efficiency of $T_IM_GGSG_LA$ was about 80% of that of natural bait made of mackerel.

  • In this paper, state of exploitation of world fishery resources after 10 years under the new regime in the sea, called the era of exclusive economic zone (EEZ) expending up to a 200 nautical miles from coastal line, was reviewed to determine effect from establishing EEZ in the world fishery production and its export/import volume based on the fishery statistics annually published by the Food and Agriculture Organization (FAO) of United Nation. The world total production from marine living resources had a trend showing a waned increase during 1970's when most of coastal states were translated into the reality of EEZ. From mid-1980's onwards, it increased rapidly, reaching about 85 million tons . Such increase in production was basically from the Pacific Ocean, accounting for more than 60% of the world total production. Fishing areas where showed increase in the production after the new regime in the sea were the southwestern Atlantic (FAO area 41) , the eastern Indian (FAO area 57) and the whole fishing areas in the Pacific except the eastern central Pacific (FAO area 77). Increase in the production from distant-water fishing countries came from the regions of the southwest Atlantic (FAO area 41) and the southwest Pacific (FAO area 81) . The production from coastal states was up from the regions of the eastern Indian (FAO area 57) , the northwest and northeast Pacific (FAO areas 61 and 67) and the southeast Pacific (FAO area 87) . It was likely that the exploitation of the fishable stocks was well monitored in the areas of the northwest Atlantic (FAO area 21) , the eastern central Atlantic (FAO area 34) and the northeast Pacific (FAO area 67) through appropriate management measures such as annual harvest level, establishment of total allowable catch etc. The marine fisheries resources that have made contribution to the world production, despite expansion of 200 EEZ by coastal states, were sardinellas, Atlantic cod, blue whiting and squids in the Atlantic Ocean : tunas which mainly include skipjack, yellowfin and bigeye tuna, croakers and pony fishes in the Indian Ocean : and sardine, Chilean pilchard, Alaska pollock, tunas (skipjack and yellowfin tuna) , blue grenadier and blue whiting including anchoveta in the Pacific Ocean. It was identified that both fishery production and its export since introduction of the new regime in the sea were dominated by such coastal states as USA, Canada, Indonesia, Thailand, Mexico, South Africa and Newzealand. But difficulties have been experienced in the European countries including Norway, Spain, Japan and Rep. of Korea. Therefore, majority of coastal states are unlikely to have yet undertaken proper utilization as well as rational management of marine living resources in their jurisdiction during the last two decades. The main target species groups which led the world fishery production to go up were Alaska pollock, cods, tunas, sardinellas, chub and jack mackerel and anchoveta. These stocks are largely expected to continue to contribute to the production. The fisheries resources which are unexploited, underexploited and/or lightly exploited at present and which will be contributed to the world production in future are identified with cephalopods, Pacific jack mackerel and Atlantic mackerel, silver hake including anchovies. These resources mainly distribute in the Pacific regions, especially FAO statistical fishing areas 67, 77 and 87. It was likely to premature to conclude that the new regime in the sea was only in favour of coastal states in fishey production.

  • 폐기되고 있는 꽂게껍질로 만든 키토산필름의 포장에 의한 반염건전갱이제품의 제조 및 저장중품질유지에 미치는 영향에 대해 실험하였다. 대조제품과 키토산필름포장제품의 수분함량은 각각 $60.6\%,\;65.0\%$로서 키토산필름포장제품의 수분함량이 $4.4\%$ 높았다. 저장중 pH, 휘발성염기질소 및 아미노질소의 증가폭은 키토산필름포장제품이 적었다. 생균수는 저장초기에 약간 감소하다가 그 이후로 계속 증가하여 대조제품은 14일째에 $8.0\times10^5/g$이었으나 키토산필름포장제품은 저장 20일째에도 $7.0\times10^5/g$이었다. TMAO는 저장중 감소하고 TMA는 증가하는 경향이었고 그 증감의 폭은 키토산필름포장제품이 적었다. TBA값과 과산화물값은 저장중 증가하다가 저장 14일 이후로 감소하였고 증가폭은 키토산필름포장제품이 적었다. 관능검사결과 저장 14일째에 대조제품은 키토산필름포장제품에 비해 현저히 품질이 떨어졌고 키토산필름포장제품은 저장 14일째에도 식용가능하였다. 이화학적 및 관능적평가로 미루어 보아 키토산필름포장 제품은 대조제품에 비해 품질유지면에서 우수하다는 결론을 얻었다.
