This paper describes the relationship between the distribution of fishing ground and E1 Nino events in the pacific Ocean which have occurred on a regular basis of 3-5 year terms. Anneal catches and catch ratios of skipjack. Katsuwonus pelamis and yellowfin tuna. Thunnus albacares largely increased during El Nino years due to the increasing of accessibility in accordance with the eastward extend of fishing ground, but vice versa during La Nina years. It is suggested that during El Nino years, the fishing grounds of Korean tuna purse seine fishery were extended to eastward in associated with the eastward advection of warm pool which was located in western equatorial Pacific Ocean during the normal state and characterized by the over 28℃ and low nutrients water masses.

Molecular Phylogeny of the Family Pomacentridae (Actinopterygii, Perciformes) Inferred from Mitochondrial 16S rDNA Sequences

Jeong Rack Koh,Ji Don Kum,Ui Wook Hwang 한국유전학회 2006 Genes & Genomics Vol.28 No.4

Damselfish (Actinopterygii, Perciformes, Pomacentridae) are a diverse and widespread family consisting primarily of marine fish found throughout tropical oceans, and they are major members of coral reef communities. The phylogenetic relationships among the pomacentrids are highly controversial due to their dramatic and complicated morphological variations, and there are striking differences between the traditional phylogeny, which is based on morphologies, and the molecular phylogeny, which is based on DNA sequences. In the present study, the phylogenetic relationships among the pomacentrids were investigated using partial mitochondrial 16S rDNA sequences from 40 species, 19 genera, and 3 subfamilies. The partial 16S rDNAs from the four pomacentrid species (Pomacentrus coelestis, Pomacentrus bankaensis, Chromis fumea and Abudefduf vaigiensis) were newly sequenced in this study. Bayesian analysis based on the 16S rDNA sequences reveals that the family Pomacentridae (BPP 74%) and the subfamily Amphiprioninae (99%), Dascyllus (90%), Stegastes (100%) and Abudefduf (100%) are monophyletic groups. However, this study also shows that the subfamily Pomacentrinae may be divided into a primitive Assemblage I and an advanced Assemblage II. Pomacentrinae Assemblage II and the subfamily Amphiprioninae are grouped together (96%), and Assemblage II appears to be paraphyletic to the subfamily Amphiprioninae. Mecaenichthys immaculatus and Acanthochromis polyacanthus, which have traditionally been considered putative chromine members, appear with Chromis cyanea within Assemblage I and within Pomacentrinae Assemblage II, respectively. This study also reveals that Chromis, Amphiprion and Chrysiptera may not be monophyletic groups. These results are generally coincident with previous molecular findings. It is very likely that the traditional pomacentrid classification scheme needs to be thoroughly re-examined.

First Record of Japanese Codling, Physiculus japonica Hilgendorf (Moridae, Gadiformes) from Korea

Koh Jeong-Rack,Moon Dae-Yeon The Korean Society of Fisheries and Aquatic Scienc 2003 Fisheries and Aquatic Sciences Vol.6 No.2

The Japanese codling fish, Physiculus japonica (family Moridae) is recorded as new to the Korean fish fauna. The specimen was fished from the South-Eastern waters off Jeju Island, Korea in March 1999. Standard length of the specimen was 343.2 mm, with a thin barbel on ower jaw, 67 soft second dorsal rays, 71 soft anal rays and 12 lateral-line above scales. Identification key of this specimen as P. japonica in the family Moridae was teethless vomer, chin barbel and well-developed black ventral light organ located on the anterior of anus. We give a new Korean name Dol-dae-gu for P. japonica.

Koh, Jeong-Rack,Moon, Dae-Yeon 한국어류학회 2003 韓國魚類學會誌 Vol.15 No.1

1986년 4월과 1999년 3월 제주도 및 거문도에서 각각 어획된 어류 중, Polymixiiformes(턱수염금눈돔목 : 국명신칭)의 Polymixiidae(턱수염금눈돔과: 국명신칭) 어류 3미가 Polymixia japonica 로 분류되어 이를 한국 미기록종으로 보고하고자 한다. 채집된 개체는 세장 147.9~158.7㎜로 몸은 측편되어 잇고 전새개골과 주새개골은 큰지늘로 덮여 있으며, 체색은 은색을 띄고 있고 등지느러미 연조부 및 꼬리지느러미 양끝에 흑색반점이 있다. 본 종의 한국명은 등지느러미 제 1~7연조 말단부분에 검은색 반점이 있는 특징과 아래턱에서 가슴지느러미 앞까지 길게 신장된 1쌍의 수염이 있는 특징으로 턱수염금눈돔속(국명신칭)의 등점은눈돔(국면신칭)으로 명명한다. The silvereye fish, Polymixia japonica, family Polymixiidae, was collected in the Cheju and Geomun islands in April 1986 and March 1999, respectively. The specimens represent the first record of the species from Korea. They ranged 147.9-168.7㎜ in standard length, they were laterally depressed, the preopercle and opercle were covered with large scales, the body was silvery, and some dark spots were observed on the soft rays of the dorsal fin and both sides of the caudal fin, The specimens are classified in the genus Polymixia based on the characteristics of blackish spots on the distal part of the 1-7th soft rays of the dorsal fin and a pair of elongated barbels extending to the pectoral fin starting from lower jaw. The species is given the Korean name Tuck- Su -Yeom -Keum -Noon-Dom -Sok, Deung- Jeom -Eun-Noon-Dom.

The purpose of this research lies in investigating the effects of switching barriers of Taekwondo gym on customer loyalty and post-purchase Behavior. The population of this research was the parents of elementary school students who are currently enrolled at the Taekwondo gym. The researchers visited 6 different Taekwondo gym in Seoul·Gyeonggi provinces to get consent from leaders to collect data after explaining the purpose of this research. Using the convenient sampling method, parents were given out surveys long with newsletter. Surveys were filled out through self assessment technique and the completed surveys were collected by visiting the Taekwondo studios. Out of the total 300 surveys, a total of 283 newsletters (94.3%) was used as data and in the real investigation. 17 uniform answers or unreliable surveys were excluded from the data. For statistical verification, exploratory factor analysis, internal consistency reliability analysis, frequency analysis, relative relation analysis, and multiple regression methods were used. The statistically verified conclusion of the research are the following. First, out of the 7 factors that contributed to the switching barriers of Taekwondo gym, continuous cost, learning cost, alternative attractiveness and mutual human relationships were shown to have a positive statistical influence on the emotional loyalty. Second, out of the 7 factors that contributed to the switching barriers of Taekwondo gym, continuous cost, learning cost, alternative attractiveness and mutual human relationships were shown to have a positive statistical influence on the computational loyalty. Third, out of the 7 factors that contributed to the switching barriers of Taekwondo gym, continuous cost and alternative attractiveness were shown to have a positive statistical influence on the recommended intention.
