The bivalve molluscan fauna of Ulsan Bay, East Sea coast of Korea, is summarized, based on original and literature data. The fauna consists of 61 species belonging to 20 families. Seven species are identified only to genus level. Two species (Carditellopsis toneana (Yokoyama, 1922), Carditidae and Fulvia hungerfordi (G.B. Sowerby III, 1901), Cardiidae) are new records for the East Sea coast of Korea, and one species (Crenella decussata (Montagu, 1808), Mytilidae) is a new record for Korea. Biogeographically, Ulsan Bay's bivalve fauna is subtropical with a predominance of tropical-subtropical species, 21 species, or 39% of the total species number, subtropical, 14 species, or 26%, and subtropical-boreal (mostly subtropical-lowboreal), 11 species, 21%, totalling 86%. A remarkable feature of the Ulsan Bay fauna is the presence of tropical-subtropical species not found in Yeongil Bay but common in tidal flats and shallow waters of the Yellow Sea and the southern part of Korea. A cold water mass appearing off the southeast coast of Korea near Ulsan in summer seems responsible for the presence of boreal-arctic species in this area.

The spider fauna in Anmyun-do Island was investigated from 20 th to 24 th Aug. 1999. As a result,94 species of 66 genera under 18 families were collected. Identified spiders were composed of Palaearctic (6%), Holarctic (7%), Oriental (0.8%), Cosmopolitan (0.8%) species. Araneid, salticid and theridiid spiders were dominant among the spiders. Common species with Japan and China were 93 (72%) and 90 (70%) species, respectively.

Since Kanda's paper on Korean scale insects in 1942, no work on scale insects has been done in Korea. The author has collected 8 species of scale insects in 5 green houses in Seoul and Suwon, of which 4 species, i.e., Chionaspis kentiae, Chrysomphalus aonidum, Planococcus kraunhiae and Aspidiotus hederae are new to Korea. Dominant species were Planococcus citri and Coccus hesperidum and common species to 4 green houses were Planococcus citri, Coccus hesperidum and Saissitia coffeae.

우리나라 연근해에 내유하는 고등어와 전갱이에 있어서 $1926\~69$년의 어획 통계 자료를 이용하여 두 어종간의 상호 관계를 해석한 결과는 다음과 같다. 1. 두 어종간의 상호 관계로서의 장기 파동은 $1927\~36$년, $1937\~45$년, $1946\~55$년, $1956\~66$년, 1967년 이후의 각기로 구분되었다. 2. 두 어종의 상호 변동은 약 10년을 주기로 교체 현상을 보이고 있다. 3. 실제의 어획량의 장기 경향에 대한 연변이는 두 어종 사이에 아무런 상관이 없다. 4. 두 어종의 상호 관계는 1기에서 다음 기로 이행될 때마다 그 양상이 달라지는 것 같다. 끝으로 논문작성에 협조하여 준 이병돈교수와 자료 경리에 협력하여 준 안화부기사에게 감사한다.

The planning of any experiment or trial involving the use of animal (material) requires the most detailed and careful consideration of the wide variety of species and strains that are now available. Unfortunately, although many research workers carefully define their requirements with respect to chemicals or complicated laboratory equipment, often they appear to be unaware of the specifications that should be similarly applied to laboratory animals and end up simply asking for a white mouse！ The aim of any user of laboratory animals should be to achieve maximum accuracy with the minimum number of animals, and it is, therefore, essential that careful consideration should be given to the choice of the animal(Bleby J, 1987). The first step when selecting an experimental animal is to specify the type needed, taking into account the following factors: 1. species, 2. breed or strain, and 3. quality, especially with respect to health and genetical status. The correct choice of species cannot be emphasized too strongly and failure to do so can sometimes have dire consequences, frequently very expensive in financial terms and sometimes extremely tragic in manifestations of human and animal suffering. In this paper, we reorganized a lot of collected articles described previously for common and scientific names of amphibians, domestic animals, birds, invertebrates, mammals, reptiles, and aquaculture as mentioned in the text.

Background: Dicyemids are parasites found in the renal sac of cephalopods. The first species of dicyemid was found from kidneys of the Korean common octopus Callistoctopus minor. Objectives: This study aimed to identify the dicyemid and investigate the effect on renal sac of host. Methods: In this study, we compared the morphological characteristics of isolate to dicyemids (Dicyema sphyrocephalum, Dicyema clavatum, and Dicyema dolichocephalum) reported from C. minor in Japan. We compared the 18S ribosomal RNA (rDNA) and cytochrome c oxidase subunit I (COI) sequences of isolate to the sequences of D. shyrocephalum and D. clavatum. The infected octopuses renal tissues were histologically compared with the tissues of uninfected individuals. Results: The morphological characteristic of this isolated species corresponds to D. sphyrocephalum. The sequences similarities of 18S rDNA and COI gene of isolate are 99.7% and 98.1% with D. sphyrocephalum. We observed morphological changes in the epithelia folds of kidney at the dicyemids attached areas. Conclusions: The present study identified the isolate as D. sphyrocephalum and this is the first report of dicyemid species from Republic of Korea. Further studies on the effects of dicyemids on growth and health status of cephalopods will be needed.

Myxosporeans are widespread cnidarian endoparasites in marine and freshwater ecosystems and several species were reported to be a threat to cultured fish causing serious diseases with mass mortality. In the present study, we found a myxosporean species in the genus Thelohanellus from the gills of the cultured common carp (Cyprinus carpio) fingerling for the first time in Korea. The morphological observation showed 500 ㎛ ~ 1 mm size, oval to circular shaped plasmodia containing spores which are pyriform at the anterior end and round at the posterior end (average size 20.1 ㎛ × 9.1 ㎛), with 5 to 6 turns of a single polar filament located in the polar capsule with an average size of 10 ㎛ × 4.6 ㎛. The 18S rRNA sequence was closest to the sequence of T. wangi among Thelohanellus species infecting gills but was not completely identical. Based on the morphological characteristics and molecular analysis results, we classified the present myxosporean parasite as Thelohanellus sp., temporarily. The prevalence and infection intensity of Thelohanellus sp. in the common carp fingerling were very high, which was thought to be the main cause of high mortality.

강원도 양양군과 인제군에 걸쳐 설악산 국립공원의 남부를 차지하고 있는 점봉산게 서식하는 거미류는 미확정 5종을 포함하여 총 27과 88녹 144종으로 나타났다. 풍부한 종 구성을 갖는 우점과의 순위는 접시거미과가 21종 (14.6%), 왕거미과 20종(13.9%), 꼬마거미과 16종(11.1%), 깡충거미과 12종(8.3%)등의 순이었고, 나머지 과는 미소 하였다. 생활형에 따르면 조망성거미는 89종(62.2%)으로 배회성 거미 55종(37.8%)보다 우세하였다. 거미류의 생태적 분포면에서 보면 구북계(Pal. spp.)가 16종 (11.2%), 전북계(Hol. spp.) 7종(4.9%) 범세계종(Cos. spp.)이 1종(0.7%)이고 한국고유종(Kor. spp.)은 25종(미확정 5종 포함, 17.4%)이었고 동양계(Or. spp.)는 한 종도 채집되지 않았다. 따라서 점봉산은 한국고유종이 차지하는 비율이 높아 가장 한국적 특성을 잘 반영하는 동시에 북방계(Pal. + Hol., 16.1%)의 거미가 우세한 지역임을 알 수 있다. 또한, 인접국가와의 공통성을 보면, 한국과 일본, 한국과 중국, 한국과 러시아 (사할린과 시베리아 포함)의 공통종은 각각 115종(80.4%), 98종(68.5%), 48종(33.6%)으로 일본, 중국과 공통성이 매우 크게 나타났으며 한·일·중·러 공통종은 39종 (27.3%)으로 나타났다. 한편, 개발치 정도와 방향에 따른 물리적 환경 변화가 생물상에 영향을 주고 있음을 알 수 있었으며, 따라서 자연환경을 보전을 위해서는 개발의 정도와 시간의 경과에 따른 생물상의 변화를 감지할 수 있는 감시 시스템이 필요할 것으로 사료되며, 거미류는 종다양성과 발생밀도가 자연상태에서 매우 높고 발견이 용이하기 때문에 조사의 진행정도에 따라 환경오염 등의 환경변화를 반영할 수 있는 지표생물로 활용 가능하다고 판단된다.

In 2011, the system for conserving and managing cetacean resources in Korea changed. The status of the cetacean bycatch was analyzed using a distribution certificate that was issued by the coast guard. During 2011.2012, 12 species were bycatch in Korean waters: three species of baleen whale and nine species of dolphin. The finless porpoise (Neophocaena phocaenoides) was the dominant species, followed by the common dolphin (Delphinus delphis), harbor porpoise (Phocoena phocoena), and Pacific white-sided dolphin (Lagenorhynchus obliquidens). Among the baleen whales, the common minke whale (Balaenoptera bonaerensis) was first and Bryde's (Balaenoptera edeni) and humpback (Megaptera novaeangliae) whales appeared in the Korea Strait and East Sea, respectively. Among the dolphins, the finless porpoise ranked first in the Yellow Sea. The common dolphin, Pacific white-sided dolphin, and harbor porpoise were more frequent in the East Sea than in other waters. The cetacean bycatch was caused mainly by pots, set nets, gill nets, and stow nets. Among the three species of baleen whale, the common minke whale was caught by pots and set nets, and comprised over 68.9% of the total bycatch in 2011 and 56.2% in 2012. Comparing the bycatch caused by fishing gears by area in 2011 and 2012, 97.9% and 99.6%, respectively, of the finless porpoise bycatch in the Yellow Sea was by stow nets. In the Korea Strait, trawl bycatch comprised 67.3% in 2011 and 73.0% in 2012, followed by gill nets, set nets, and pots targeting finless porpoise and common minke whales. In the East Sea, gill nets were responsible for 46.7% in 2011 and 61.2% in 2012, followed by set nets and pots.
