  기능성 지질 추출 소재로서 Fish Frames의 지질성분 특성	수산가공 부산물인 fish frame을 기능성 지질 추출소재로서의 이용 가능성을 검토하기 위하여 6종의 fish frame(붉은메기, 연어. 삼치, 고등어, 붕장어, 가다랑어 등)에 대한 지질성분 특성에 대하여 살펴보았다. Fish frame에 대한 어류 뼈의 수율은 가다랑어가 64.2%로 가장 높았고, 다음으로 연어(57.9%), 붕장어(54.6%), 붉은 메기(42.0%), 삼치(41.7%)등의 순이었으며, 고등어가 32.6%로 가장 낮았다. 어류 뼈 유래 총 지질 중 중성 지질의 함량은 삼치가 23.3g/100g으로 가장 많았고, 다음으로 붕장어 (21.5 g/100 g), 연어 (16.0 g/100 g), 고등어 (15.5 g/100 g)의 순이었으며, 가다랑어와 붉은 메기의 경우 다른 4종의 어류에 비하여 확연히 낮았다. 붉은 메기를 제외한 5종 어류의 중성지질 모두가 근육 및 뼈 지방에 관계없이 TG가 주성분(근육지방, 71.9-83.2%; 뼈지방, 74.2-86.9%)이었고, 다음으로 근육지방의 경우, FFA(8.1-19.2%), 뼈지방의 경우 FS(5.5-l5.5%)이었다. 붉은 메기의 경우, 중성지질의 주성분인 TG의 조성비(근육지방, 48.6%; 뼈지방, 45.3%)가 다른 어류에 비하여 확연히 낮았고, FFA의 조성비 또한 근육지방(41.6%) 및 뼈지방 (43.4%)에 관계없이 모두 5종의 어류에 비하여 확연히 높았다. 어류 뼈의 중성 지질의 EPA＋DHA 조성은 연어 가 29.3%로 가장 높았고, 다음으로 가다랑어(27.1%), 붉은 메기(27.0%), 고등어(25.7%), 삼치(21.6%)의 순이었고, 붕장어의 경우 14.9%에 불과하였다. 이상의 수율, 중성지질 함량, 유리지방산 조성 및 EPA＋DHA 조성 비율의 결과로 미루어 보아 기능성 지질 추출원으로는 연어가 가장 우수하였고, 다음으로 삼치, 붕장어, 고등어, 가다랑어 등의 순이었으며, 붉은 메기의 경우 부적절하다고 판단되었다.	김정균,한병욱,김혜숙,박찬호,정인권,최영준,김진수,허민수	한국식품영양과학회	상세보기
  伊勢？におけるあなごかごのマアナゴに？する網目選？性	？？This study estimated the mesh selectivity of net pots for white-spotted conger eel Conger myriaster in Ise Bay in order to reduce the bycatch of conger eel under 250 mm total length, the size limit for landing at fish markets from October and November by the Stock Recovery Plan in Ise and Mikawa Bay. Experimental fishing was carried out 13 times from June 2003 to November 2004 by using six mesh sizes: 12.6, 14.3, 16.1, 17.9, 20.2 and 27.8 mm, and the mesh selectivity master curve was estimated by the SELECT method. The mesh selectivity master curve was estimated to be s(R)=exp (-16.20+11.84R)/1+exp (-16.20+11.84R), where R is the ratio of fish girth to mesh size. Total lengths of 50% selection for the six mesh sizes given above were calculated to be 224, 245, 266, 287, 313 and 367 mm, respectively. According to the proportion of conger eel landings of each fish size category at Wakamatsu fish market, conger eel landings of a total length around 300 mm account for about 20% of the total landings. Thus, in order to retain conger eel over 300 mm, returning undersized fish less than 250 mm where possible, and use of net pots with a mesh size of 16.1 mm is considered acceptable for the fishermen in Ise Bay at the present time.

  Evaluating the approaches of habitat suitability modelling for whitespotted conger (Conger myriaster)	Abstract Habitat suitability models (HSMs) are effective for evaluating habitat suitability and guiding the conservation and exploitation of fishery resources. Using species presence-absence and environmental data collected from a 2011？2015 of bottom trawl survey, we developed and evaluated four habitat suitability models to examine the trends of habitat suitability for a long-distance migration fish, whitespotted conger (Conger myriaster). Generalized additive model (GAM) showed a higher explanatory power than generalized linear model (GLM) and random forest model (RF). Depth and bottom temperature were the most powerful predictors for conger distribution in spring and fall, respectively. We conducted cross-validation study to evaluate the predictability of these models, and random forest model showed consistently better performance than the other models. The spatial distribution of suitable habitat predicted by the best model was mapped in the survey area to inform the exploitation of this species, which showed remarkable annual variations in autumn.

  Differences and Variations among Anguilla japonica, Muraenesox cinereus and Conger myriaster from the Yellow Sea	Genomic DNAs were extracted from the muscle of twenty-one specimens of three eel species collected in Anguilla japonica (AJ), Muraenesox cinereus (MC) and Conger myriaster (CM) from the Yellow Sea, respectively. In the present study, 7 oligonucleotides primers generated 191 specific loci in the AJ species, 226 in the (MC) species and 181 in the CM species, respectively. The primer BION-02 generated the most loci (a total of 83), with an average of 11.86 in the AJ species. The specific loci generated by oligonucleotides primers exhibited inter-individual-specific characteristics, thus revealing DNA polymorphisms. With regard to average bandsharing value (BS) results, individuals from Conger myriaster species (0.808) exhibited higher bandsharing values than did individuals from Muraenesox cinereus species (0.729) (P<0.05). The longest genetic distance (0.430) displaying significant molecular difference was also between individual no. 01 within Anguilla japonica eel species and individual no. 04 within Anguilla japonica species. In this study, the dendrogram resulted from reliable seven oligonucleotides primers, indicating three genetic clusters composed of group I (ANGUILLA 01~ANGUILLA 07), group II (MURAENESOX 08~MURAENESOX 14) and group III (CONGER 15~CONGER 21). The existence of species differentiation and DNA polymorphisms among three eel species were detected by PCR analysis. As mentioned above, a dendrogram revealed close relationships between individual identities within three eel species. High levels of a significant genetic distance among three eel species showed this PCR approach is one of the most suitable tools for individuals and/or species biological DNA studies.

  Differences in organochlorine accumulation accompanying life history in the catadromous eel Anguilla japonica and the marine eel Conger myriaster	In order to examine the ecological risk for organic pollutants in diadromous fish migrating between sea and freshwater, organochlorine compounds (OCs) were determined in the catadromous eel Anguilla japonica having marine, estuarine and freshwater residence life histories. The eels were collected in Japanese coastal areas. We also compared the OCs accumulation with the marine eel Conger myriaster, which has a similar life history as A. japonica in the marine environment. The ontogenic changes in the otolith strontium (Sr) and calcium (Ca) concentrations were examined along the life history transect to discriminate the migration type. There were generally three different patterns, which were categorized as 'marine residence' (spent most of their life in the sea and did not enter freshwater), 'estuarine residence' (inhabited estuaries or switched between different habitats), and 'freshwater residence' (entered and remained in freshwater river habitats after arrival in the estuary) according to the otolith Sr:Ca ratio. There were generally no correlations between OCs such as Dichlorodiphenyltrichloroethanes (DDTs), Hexachlorobenzene (HCB), Hexachlorocyclohexanes (HCHs) and Chlordanes (CHLs) accumulation and each biological characteristic such as TL, BW and age in A. japonica. A positive correlation between the lipid content and concentrations of OCs were found. Additionally, the concentrations of HCB, HCHs, CHLs and DDTs in A. japonica were significantly higher than those of C. myriaster, associating with the higher lipid contents (14% on average) in the former than the latter eels (9% on average). A negative linear relationship was found between the otolith Sr:Ca ratios and concentration of each OCs in A. japonica. The ecological risk of OCs increase as the freshwater residence period in the eel becomes longer. It is clear that migratory histories and lipid contents directly affected OCs accumulation in the anguillid eels.	Arai, Takaomi,Takeda, Akina	Springer-Verlag	상세보기

  Conger myriaster	붕장어	강원도	식용,약용	계절에 관계없이 바다에서 참갯지렁이를 미끼로 사용해 장어 (붕장어)를 잡아서 탕, 구이, 회로 먹는다. 예전에는 가을에만 잡았으나 요즘에는 6월부터 11월까지 잡아 큰 것은 구이로 먹고 작은 것은 탕이나 회로 먹는다. 장어(붕장어)를 낚시로 잡아 소금을 치거나 양념을 해서 구워 먹거나, 푹 달여서 먹는데 기름기가 많아서 보양식이 된다.
