The feeding habits of the Pacific cod Gadus macrocephalus were studied using 620 specimens collected by bottom trawl and pound net in the Southeast sea of Korea, from February 2012 to June 2013. Of 620 specimens, 192 contained food and 428 were empty. The total length (TL) of individuals used in this study ranged from 20.4 to 95.2 cm. Pacific cod mainly consumed Pisces, Macrura, and Cephalopoda. Its diet also included small quantities of Anomura, Brachyura, Mysidacea, Isopoda and Amphipoda. The proportion of Pisces in prey items increased with increasing Pacific cod length, but seasonal difference was not observed. The proportion of Macrura and Cephalopoda decreased with growth, and seasonal differences were apparent. Macrura were taken there mainly from autumn to winter, whereas Cephalopoda were consumed from spring to summer.

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 contents [average(minimum∼maximum), Unit:mg/kg] of hazardous heavy metals(Hg, Cd and Pb) were estimated from 951 fishery products in Seoul(468 fishes,373 shellfishes, 39 crustaceans and 71 others) from January to December in 2001 by Atomic Absorption Spectrometer. Hg contents showed in shellfishes [0.033(N.D.∼0.19)]>others(0.026(N.D.∼0.11)]>crustaceans[0.026(N.D.∼0.09)]>fishes[0.018(N.D.∼0.19)], Misgurnus mizolepis(0.19) and Tegillarca granosa(0.19) were the highest. Pb content were shellfishes [0.223(N.D.∼l.38)] >fishes[0.213(N.D.∼1.68)]>others[0.15(N.D.∼0.39)]>crustaceans[0.144(N.D.∼0.444)], and Misgurnus mizolepis (1.68)>Hypomesus olidus(1.44)>Tapes philippinarum(1.38)>Anguilla japonica(1.35). Also, Tegillarca granosa(1.85) was the most Cd contents among shellfishes[0.288(N.D.∼1.85)].

The purpose of this study was to investigate certain heavy metals (Hg, Pb, Cd, Cu) in 144 samples of cephalopods, to identify weekly heavy metal intakes and to evaluate potential health risks. The average concentrations in the arm, expressed in mg/kg, were: Hg 0.017 (less than the limit of detection (LOD) to 0.059), Pb 0.024 (less than the LOD to 0.092), Cd 0.030 (less than the LOD to 0.627) and Cu 2.536 (less than the LOD to 5.837). The average concentration in the internal organs, expressed in mg/kg, were: Hg 0.063 (from 0.008 to 0.543), Pb 0.579 (less than the LOD to 2.344), Cd 15.200 (from 0.654 to 75.29) and Cu 201.706 (from 2.412 to 856.4). Heavy metal concentrations were higher in the organs than in the arm. Of the four heavy metals, the ratio of internal organs to arm was highest for cadmium. The weekly intakes of Hg, Pb, Cd and Cu from Octopus minor were 0.2%, 0.08%, 0.20% and 0.00%, respectively from the arm, and 1.0%, 0.96%, 92.28% and 0.05% from the internal organs as compared to PTWI (provisional tolerable weekly intakes) established by the FAO/WHO Expert Committee for Food Safety Evaluation.

연체동물 우리말 사용에 따른 혼란을 해결하고, 한국산 연체동물 총목록 작성의 예비연구로써 이미 국내에 보고된 분류군의 우리말 이름을 수집, 조사하였다. 우리말 이름을 가진 종은 무판류 1종, 군부류 16종, 복족류(고둥류)500종, 이매패류(조개류) 226종, 굴족류 4종, 두족류 34종으로 모두 781종이었다. 그리고 우리말 이름의 어원과 조사결과 나타난 문제점을 제시하고, 우리말 이름의 통일 작업이나 제정에 필요한 원칙을 제언한다.

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).

꼬마새우과 (Family Hippolytidae)에 속하는 넓적뿔꼬마새우 (Latreutes planirostris)는 우리나라의 서해, 남해안 해역과 동중국해를 공유하는 일본(훗카이도, 혼슈우, 큐유슈우), 중국, 홍콩 등지에 주로 분포하고, 우리나라에서는 연중 출현하며, 특히 여름과 겨울에 대량 출현한다. 넓적뿔꼬마새우는 연안생태계에서 상위포식자인 두족류나 어류의 먹이인 동시에 초식자를 섭이하는 먹이사슬의 중간단계로서 중요한 역할을 담당하고 있다 (Omori, 1974; Yang and Tan 2000). (중략)
