The snailfishes (Scorpaenoidei: Liparidae) is a large group requiring taxonomic reviews because of a potential taxonomic confusion due to its great similarity in external morphology between species and a variation of its body color with size. Molecular phylogeny and taxonomic review were conducted for 10 species in 3 genera reported around the Korean waters, which facilitate understanding interrelationship within its family, and further management of fisheries resources. Molecular phylogeny using mitochondrial COI (mtCOI) and nuclear RAG2 (nRAG2) sequences indicates that the reciprocal monophyly of the three genera (Careproctus, Crystallichthys, and Liparis) were supported except Crystallichthys matsushimae, being closely related to Careproctus notosaikaiensis in only mtDNA COI topology. Liparis ingens Gilbert and Burke (1912) was reported as a distinct species differing from L. ochotensis. However, in the present study, comparing L. ingens from Korea with L. ochotensis from Japan and Russia, the two species were well corresponded in their morphology and molecule, therefore, we suggest L. ingens to be treated as a junior synonym of L. ochotensis.

On the Korean Peninsula, eleven species of the genus Liparis (Orchidaceae) have been recorded, and three species are presumed to belong to the L. makinoana complex. These are L. koreana, L. japonica, and L. makinoana. Liparis japonica and L. makinoana are distributed in South Korea, but the distribution of L. koreana has not been confirmed. Liparis japonica and L. makinoana are morphologically very similar, making it difficult to classify them. Recently, L. japonica and L. makinoana in Japan were reclassified into three species. One of them is an amended species of L. makinoana, and the other two species were described as new species, specifically L. longiracemosa and L. suzumushi. It was confirmed that the three species are distributed in South Korea. Here, we provide a distribution map, photographs of the three new species, and a comparison of their morphological characteristics.

한국에서 자생하고 있는 Liparis 속의 11분류군 중 Liparis koreana (Nakai) Nakai을 제외하고 대부분은 경기도와 강원도부터 제주도 및 도서지방을 포함한 전국에 분포하고 있다. 최근 국내 Liparis japonica(Miq.) Maxim. 로 알려진 개체군에 대해 학명이 잘못 적용된 결과가 보고되었고, 본 개체군을 포함하여 Liparis makinoana complex에 대한 국내 개체군에 대해 재검토를 하였다. 그 결과 L. makinoana complex은 제주 Type (Type 1)과 내륙의 2 Types (Type 2, 3)으로 3 Types가 확인되었다. Type 1-3은 형태학적으로 유사하지만, 종의 형태학적 형질과 개화기, 그리고 분포지역에서 뚜렷한 차이를 보였다. Type 1은 꽃이 가장 크며, 순판은 넓은 난형이고, 개화기는 5-6월이며, 제주도에서 분포하는 것으로 확인되었다. Type 2는 꽃이 중간크기이며, 순판이 난형이고, 개화기는 6월 중순-7월 중순이며, 중북부지방에 주로 분포한다. 반면에, Type 3는 꽃이 가장 작고, 순판이 좁은 난형이고, 개화기가 6월 초-7월 초이며, 백두대간을 따라 분포하는데, Type 3는 Type 1과 Type 2에 비해 화서가 길다.

꼼치, Liparis tanakai는 미거지, 물메기와 함께 꼼치과(Liparidae), 꼼치속(Liparis)에 속하는 어류로서 우리나라 동남연해 및 일본 연해에 분포하며(정, 1977), 심해성이며 식용으로 이용되나, 비교적 가격이 낮다. 그러나, 꼼치에 대한 연구는 그다지 많지 않다. 꼼치의 난과 자치어에 대하여 단편적으로 1959년 청산에 의하여 발표된 되었고, Kawasaki(1983)의 생활사에 대한 연구와 김 등(1996)에 의한 꼼치의 난발생과 부화자어에 대한 보고가 있다. (중략)

Feeding habits of juvenile Liparis tanakai collected from the eelgrass bed in Kwangyang Bay were studied. L. tanakai (2.0-6.0 cm SL) was a carnivore which consumed mainly amphipods (caprellids and gammarids) and caridean shrimps. Its diets also included a large amount of copepods, polychaetes and small fishes. Three distinct ontogenetic feeding groups were noted: (1) the individuals of 2.0-2.5 cm SL preyed heavily on copepods, (2) individuals of 2.5-4.0 cm SL fed mainly on amphipods. (3) individuals over 4.0 cm SL preyed mainly on caridean shrimps and small fishes. The dietary breadth of each size class showed relatively low value, and this means that juvenile L. tanakai depends on only few kinds of food organisms.

A single specimen of Liparis punctulatus (30.9 mm standard length) belonging to the family Liparidae, was collected in the waters off Busan on 4 August, 2016. This species is characterized by a single pair of nostrils, unlike other Liparis species. It is distinguished from L. ochotensis by the numbers of dorsal, anal, pectoral fin rays and the location of the gill opening (above the pectoral fin in L. punctulatus vs. extending ventrally in front of the pectoral fin). In the molecular analysis, 514 bp of 16S rRNA gene of the specimen in this study were identical to that of L. punctulatus from NCBI GenBank (K2P distance < 0.002). This is the first record of the species in Korea based on a voucher specimen, and we follow the Korean name "Kko-ma-kkom-chi" for this species proposed by Myoung et al. and Kim et al.

This study analyzed the reproductive biology, fishing characteristics and changes in fishing business of Liparis tanakae, snailfish collected from September to March. It was the period when they were mainly caught from 2018 to 2020. The average length was generally small in September and October and was large in January and February. The average body weight was generally around 1,500 g and the average body weight in autumn was lower and in winter was higher. The sex ratio of male and female was 0.40:0.60 (��2 test, p < 0.05). The spawning period was estimated from October to February and the main spawning period was from December to February through the GSI. The egg diameter of matured staged female L. tanakae was 0.11-1.48 mm, which was the main spawning period and the relationship between body weight and fecundity was F = 1849TL0.1093 (r2 = 0.2401). The monthly catch of L. tanakae was high from November to February, the time of migrating to the coastal area. Coastal gillnet fishery showed the highest percentage of all fisheries catching Liparis spp. Liparis spp. were caught at a high rate in winter in Chungnam, Jeonbuk, Jeonnam and Gyeongnam region, and revenue and cost was increased since 2017. Assuming a situation where there is no catch of Liparis spp., the fishing profit that can be obtained was the highest in Gyeongnam region and the dependence on fishing of Liparis spp. by coastal gillnet fishery was high.

Tanaka’s snailfish, Liparis tanakae (Gilbert and Burke, 1912), is distributed throughout the coasts of Korea. To clarify the population structure of L. tanakae, we analyzed the morphological and genetic variation among individuals sampled from three localities surrounding the Korean peninsula: Boryeong in the Yellow Sea, Jinhae in the Korea Strait and Pohang in the East Sea. Principal component analysis based on 20 morphometric characteristics revealed two slightly distinct groups (Boryeong vs. Jinhae and Pohang). However, canonical discriminant analysis clearly revealed three groups, separated according to locality. Pairwise differentiation index (F_ST) comparisons based on 762-base pairs mitochondrial cytochrome b gene sequences showed that Boryeong significantly differed from Jinhae and Pohang, but Jinhae and Pohang did not significantly differ from each other. Our findings suggest that Korean L. tanakae comprise at least two groups. Further studies using more sensitive DNA markers, such as microsatellite DNA, are required.

The Feeding habits of larval Liparis tanakae collected from the Nakdong River estuary were studied. L. tanakae [3.8-10.6 mm notochord length(NL)] was a carnivore thatconsumed mainly copepods. Its diet also included small numbers of free-living flatworms (Macrostomida), tintinnids, cladocerans, and polychaetes larvae. To evaluate ontogenetic changes in dietary composition, three size groups were designated: 3-5, 5-7, and >7 mm. Copepods were the most important prey items for all size groups. The smallest size group frequently preyed on polychaete and bivalve larvae, along with copepods. As notochord length increased, the numbers of cladocerans and Macrostomida increased relative to those of polychaete and bivalve larvae.

쏭뱅이목, Sorpaeniformes의 꼼치과, Liparidae 어류는 남극, 북극, 대서양 및 태평양에 걸쳐 광범위하게 분포하며(Nelson, 1994), 전세계적으로 24속, 317종(Froese and Pauly, 2003), 우리나라에는 2속 7종만이 보고되어 있다(Kim and Kim, 1997). 국내에서는 꼼치과 어류증 꼼치, Liparis tanakae가 식용으로 즐겨 이용되며, 겨울철 남해안에서 주로 어획된다. (중략)
