두족류의 우리말 사용에 따른 혼란을 해결하고, 한국산 두족류 총 목록 작성의 예비연구로써 이미 국내에 보고된 분류군의 우리말 이름을 수집 조사하였다. 우리말 이름을 가진 두족류의 어원과 조사 결과 나타난 문제점을 제시하고, 우리말 통일 작업이나 제정에 필요한 원칙을 제언하였다. 제언을 토대로 갑오징어목 2고 14종, 오징어목 7과 17종, 문어목 3과 7종에 대한 우리말 이름을 재정립하였다.

We examined the distribution and biology of cephalopods collected during joint Korean-Russian surveys of the East/Japan Sea in 1993 and 1994. A total of six species of cephalopods belonging to five families were collected during the surveys: one sepiid squid, four teuthid squids, and one octopus.

The infection status of marine fish and cephalopods with Anisakis simplex third stage larva (L3) was studied over a period of 1 year. A total of 2,537 specimens, which consisted of 40 species of fish and 3 species of cephalopods, were purchased from the Cooperative Fish Market in Busan, Korea, from August 2006 to July 2007. They were examined for A. simplex L3 from the whole body cavity, viscera, and muscles. A. simplex L3 were confirmed by light microscopy. The overall infection rate reached 34.3%, and average 17.1 larvae were parasitized per infected fish. Fish that recorded the highest infection rate was Lophiomus setigerus (100%), followed by Liparis tessellates (90%), Pleurogrammus azonus (90%), and Scomber japonicus (88.7%). The intensity of infection was the highest in Gadus macrocephalus (117.7 larvae per fish), followed by S. japonicus (103.9 larvae) and L. setigerus (54.2 larvae). Although abundance of A. simplex L3 was not seasonal in most of the fish species, 10 of the 16 selected species showed the highest abundance in February and April. A positive correlation between the intensity of L3 infection and the fish length was obvious in S. japonicus and G. macrocephalus. It was likely that A. simplex L3 are more frequently infected during the spring season in some species of fish. Our study revealed that eating raw or undercooked fish or cephalopods could still be a source of human infection with A. simplex L3 in Korea.

본 연구는 1991년 2월부터 1992년 7월까지 한국 해역에 분포하는 오징어의 위내용물을 분석한 것이다. 위내용물의 종류를 살펴보면, 해조류, 갑각류, 두족류, 어류 외 동정 불가능한 것도 나타났다. 먹이생물중 어류를 가장 많이 먹었으며, 그 다음으로 두족류, 갑각류, 해조류 순으로 섭이하는 것으로 나타났다. 위의 만복도 조성에서 공위가 $58.00\%$이었고, 만복된 위는 $6.37\%$이었다. 여름과 가을 계군은 어류를 가장 많이 섭이한 반면, 겨울계군은 두족류를 매우 우점적으로 섭이하였다. 해조류와 갑각류는 세 계군 모두 매우 적은 양이 섭이되었다. 오징어의 주요 먹이생물은 어류이었고, 계군에 따른 위내용물의 차이는 없었다.

The feeding habits of brown barracuda (Sphyraena pinguis) were analyzed using the stomach contents of monthly samples collected from coastal waters of Gadeok-do, Korea from January to December, 1998. Brown barracuda occurred mainly from summer to autumn in the study area, and ranged from 15 to 35 cm in standard length. Brown barracuda was a piscivorous fish which, mainly consumed teleost fish such as anchovy (Engranlis japonicus) and chefoo thryssa (Thfssa kammalensis). Its diet also included small quantities of shrimp and cephalopods. Although smaller fishes (<25 cm SL) consumed shrimp and cephalopods as well as fish, larger fishes (>30 cm SL) consumed exclusively teleost fish. The prey size increased with increase of fish size.

The feeding habits of olive flounder, Paralichthys olivaceus were studied using 126 specimens collected from coastal waters off Taean, Korea from April 2008 to March 2009. The total lengths of P. olivaceus ranged from 16.7 to 40.6 cm. P. olivaceus was a piscivore that consumed mainly fishes. The diet also included small quantities of shrimps, cephalopods, polychaetes and mysids. Although, P. olivaceus mainly consumed fishes of all size classes, some degree of change in diet composition was found; i.e. after fishes, smaller individuals fed more on shrimps, whereas larger individuals consumed more cephalopods.

거문도 연안해역에서 채집된 달고기($Zeus$ $faber$) 462개체의 식성을 조사하였다. 달고기의 표준체장(SL)은 7.8~40.2 cm 범위였다. 달고기의 위내용물을 분석한 결과 달고기는 갈치 ($Trichiurus$ $lepturus$), 고등어 ($Scomber$ $japonicus$), 노랑벤자리($Callanthias$ $japonicus$), 전갱이($Trachurus$ $japonicus$)와 같은 어류(Pisces)를 주로 섭식하는 어식성어류였으며, 어류 중에서 갈치를 가장 선호하였다. 어류 다음으로 두족류 (Cephalopoda), 새우류 (Macrura), 난바다곤쟁이류 (Euphausiacea)를 섭식하였지만 그 양은 많지 않았다. 체장 15 cm 이하의 개체에서는 어류와 두족류를 주로 섭식하였다. 두족류의 비율은 체장 증가에 따라 감소한 반면, 어류의 비율은 증가하였다. 어류는 체장 15 cm 이상의 개체에서는 위내용물 중 대부분을 차지하였다.

The diet composition of common flying squid Todarodes pacificus was studied using 1,084 specimens collected through trawl and jigging from June 2018 to June 2020 in the East Sea of Korea. The mantle length (ML) of the collected individuals ranged from 13.6 to 31.1 cm. Todarodes pacificus is a carnivore. In the study area, T. pacificus was observed feeding mainly on fish and cephalopods, in addition to small quantities of crustaceans. The calculated trophic level value for T. pacificus was 4.10. Small individuals (ML, <18.0 cm) mainly fed on cephalopods, while intermediate (ML, 18.0-23.0 cm) and large (ML, ≥23.0 cm) individuals fed mainly on fish and occasionally on cephalopods. Overall, as the body size of T. pacificus increased, the mean weight of the consumed prey increased (one-way ANOVA, P<0.05).

In this study, an attempt has been made to analyze the morphology of Cephalopods distributed in Korea and collected samples from South-East Asian countries including Thailand, Indonesia, Vietnam, and China. A phylogenetic analysis was performed using the mitochondrial gene, Cytochrome c oxidase subunit I (COI) to understand the genetic divergences of the species and validate their origins. For achieving the objectives, samples were collected directly from Thailand Hat Yai, Songkhla, Indonesia Medan, Vietnam Ho Chi Minh, and Vung Tau in August 2015 and from China in September 2015. A total of 23 species of Cephalopods were identified falling under three orders, four familyies and nine genus. The species were distributed under Order: Octopoda (1 family, 3 genus, and 9 species), Order: Sepiolioda (1 family, 2 genus, and 8 species), and Order Teuthoidea (2 family, 4 genus, and 6 species). 23 species which is 1 family 3 genus 9 species in Octopoda, 1 family 2 genus 8 species in Sepiolioda, 2 family 4 genus 6 species in Teuthoidea. Phylogenetic analysis using COI gene was conducted for 18 species. For the remaining 5 species sequencing results showed severe variation and hence were not considered further. The COI phylogenetic analysis for the 18 species of Cephalopods were found consistent with the morphological identification. The excluded species will be subjected for a further detailed analysis.
