  • The fluctuation in the abundance and species composition of fish was investigated using gape net in Dolsan District of Yeosu Korea from July 2015 to April 2016. A total of 1,331 fishes were sampled and classified into 30 orders, 42 families, and 53 species. The dominant orders are Perciformes including 21 famailies and 24 species, followed by Scorpaeniformes including 7 families and 13 species, and Clueiformes including 6 families and 6 species. Among the 53 fish species collected, Engraulis japonicus was the most frequent species occupying 43.5%, followed by Argyrosomus argentatus (23.8%), and Leiognathus nuchalis (22.4%). The monthly diversity, evenness, and richness index were 1.83-2.90, 0.76-0.95 and 3.06-6.40.

  • The feeding habits of Lateolabrax japonicus were studied based on an examination of the stomach contents of 344 specimens collected monthly from January to December, 2005 in coastal waters off Dolsan-do, Yeosu. The standard length (SL) of specimens ranged in 8.7~52.8 cm. L. japonicus is a piscivore that consumes mainly teleosts such as Engraulis japonicus, Trachurus japonicus, and Acanthogobius flavimanus. Its diet also includes Macrura, Amphipoda, Cephalopoda, Polychaeta, Mysidacea, and Branchyura. Small individuals (<25 cm SL) consume mainly Amphipoda and Macrura. The proportion of these prey items decreases with increasing fish size, and this decrease paralleled the increased fish consumption.

  • A study on the species composition and seasonal variations of fishery creatures caught by a funnel net was carried out in the coastal water off Dolsan Island, Yeosu from 2002 to 2003. During the study period, a total of 23 fishery creatures species were caught. Seabream(Acanthopagrus schlegeli), sea bass(Lateolabrax japonicus), mullet(Mugil cephalus), puffer(Takifugu niphobles) and rockfish(Sebastes inermis) predominated. These five species accounted for 85.1% of the total number of fishery creatures caught. Seasonal peaks of number of species occurred in summer, while those of number of individuals occurred in autumn. The lowest number of species and individuals were observed in winter. The large annual variation of diversity indices were observed from May to August. These large annual variation of diversity indices were mainly due to predominance of seabream, sea bass and mullet which accounted for most of all fishery creatures caught. The seasonal variations of fishery creatures showed that sea bass and mullet were caught mainly from spring to summer, seabream and puffer were caught mainly in autumn, and rockfish and brotula(Hoplobrotula armata) were caught mainly in winter.

  • The purpose of this thesis was to design and develop restaurant uniforms for Yeosu and Suncheon-City using local cultural resources by investigating the present situation of restaurant uniforms. The study was conducted through literature review and practical research on uniform designs. The practical research included investigating and analyzing the recent uniform designs of 60 spots in both cities and the preference of local cultural resources, finally suggesting eight restaurant uniform designs and four original samples. It was found that most workers in both cities wore shirts and pants or aprons as uniforms and also that the restaurant uniforms had many problems, such as poor designs, functionality, and the lack of local characteristics. According to these results, a design concept called 'Colorful Night Sea' was built for Yeosu using a design motive of a Yeosu Expo symbol, a Big-O Show shape, and Dolsan Gat flowers. For Suncheon-city, a design concept called 'A Rural Landscape' was built using a design motive of Nagan Eupseong and a field of reeds in Suncheon Bay. The restaurant uniform items included a top (shirt or blouse), pants, apron, and headdress in both cities. This study is meaningful as it helped improve the local image and economic situation, by proposing distinct uniforms designed by using local cultural resources.

  • It was studied on the choice of potential area for red tide occurrence from oceanographic factors. Oceanographic factors of favorable marine environmental conditions for the red tide formation included warm water temperature, low salinity, high suspended solid, low phosphorus, low nitrogen. It was founded the potential areas for red tide occurrence in August 2000 by GIS conception: Yeosu~Dolsan coast, Gamak bay, Namhae coast, Marado coast, Goheung coast, Deukryang bay, respectively.

  • Menziesia sebastodis (Capsalidae: Monogenea) is found and described from the gill filaments and the gill rakers of the black rockfish, Sebastes inermis, caught at Dolsan Island, off the south coast of Yeosu, Jeollanam-do, Korea. The genus Menziesia is distinguished from other related genera Benedenia, Megalobenedenia and Trochopus, by septate haptors and the morphology of copulatory organs. M. sebastodis can be differentiated from other Menziesia species by the longer and slenderer posterior anchor, and the location of accessory gland reservoir. This is the first record of the genus Menziesia in Korea.

  • The aims of this study was to optimize the extraction conditions of sinigrin from Dolsan leaf mustard. Dolsan leaf mustard (Dolsan-eup, Yeosu-si) harvested during at May 2014 was used for sinigrin extraction. After the extraction of sinigrin using 50% $CH_3CN$, 10% $NH_4Cl$, 60% $CH_2OH$, and 70% $CH_3OH$, the sinigrin content was measured by HPLC analysis. The results showed that sinigrin content was highest with 50% $CH_3CN$ solvent extraction and UV detector sensitivity was greater at 228 nm rather than at 242 nm. The sinigrin concentrations of leaf, stem and root with 50% $CH_3CN$ extraction were 345 ppm, 728 ppm, and 539 ppm, respectively. After extraction of the different parts of Dolsan leaf mustard, The standard retention time by HPLC analysis of sinigrin content was 2.054, 2.032, 2.059, and 2.035 min from the root, stalk, and leaf, respectively. On the other hand, HPLC analysis showed that the leaf extracts contained glucoraphanin, one of glucosinolates. The optimum time and extraction solvent for the sinigrin extraction from Dolsan leaf mustard was found to be 24 hr with 50% $CH_3CN$ solvent. In addition, opotimum UV detector k at 228 nm. These results showed that the optimum extraction conditions for Dolsan leaf mustard were 24 hr extraction with 50% $CH_3CN$ solvent. In addition, the optimum wavelength of UV detector was determined to be 228 nm for sinigrin analysis. Therefore, this study could provide a useful information for sinigrin extraction and its systematic analysis during the storage.

  • The species composition of bycatch species in the coastal waters of Yeosu were determined by monthly sample collection using a gape net with wings in 2014. Of a total of 32 fishes collected, the dominant species were Ammodytes personatus, Conger myriaster leptocephali, Sebastes inermis, Trichiurus lepturus, Thryssa kammalensis, Leiognathus nuchalis, Syngnathus schlegeli, Thryssa adelae and Hexagrammos otakii. These 9species accounted for 95.2% of the total number of individuals collected. Most of the fish caught were juveniles and small fishes. Based on the results of multidemensional scaling (MDS) analysis, the bycatch fishes were divided into five group.

  • The genetic relationships of 14 Dolsan leaf mustard (Brassica juncea) lines were analysed using random amplified polymorphic DNA (RAPD) analysis. Thirty nine random primers were tested and seven primers which showed polymorphism were selected. The amplified fragments ranged from 0.2 to 3.5 kb in size. The number of bands amplified in each primer showed the variations ranging from 2 to 27, with an average of 8.7. Based on the UPGMA cluster analysis, 14 lines were separated into three groups. The results showed that RAPD analysis was useful in the genetic diversity and in the cross combination of the $F_1$ hybrid of leaf mustard.
