  • Two new marine sponges in genus Suberites, S. hataedoensis n. sp and S. waedoensis n. sp have been collected from Hataedo Island and Waedo Island, Korea during 2005-2006. S. hataedoensis n. sp. is similar to S. durissimus in the spicule composition and texture. However, they differ in growth form, skeleton and surface. S. waedoensis n. sp. is similar to S. japonicus in spicule composition and skeleton. However, they differ in growth form, surface and texture.

  • Cholesteryl Ester Transfer Protein (CETP) mediates the transfer of cholesterol ester and triglyceride between high-density lipoprotein (HDL) and other low-density lipoproteins, therefore, it might influence HDL levels. The levels of HDL is closely related to the atherogenic diseases in human and there were several reports that the trasgenic mice expressing CETP had much worse atherosclerosis than non-expressing control one. Therefore, selective inhibitors of CETP have the potential to be used as antiatherosclerotic agents. Continued screening for potent inhibitors of CETP led to the isolation of Suberitenone B from marine sponge. Suberitenone B, sesterterpenoids of a new skeletal class have been isolated from the sponge Suberites sp. collected from King George Island the Antartic. The structure of the metabolite has been determined by NMR experiments and chemical methods.

  • A large number of Demospongiate have been collected from 18 localities in Cheju Island and its adjacent waters during the period from 1970 to 1991. The identified Demospongiae consist of 67 species, 40 genera and 30 families. Among them 11 species were new to Koera; Oxeostilon fernaldi, Microciona gradalis, Tedania ignis, Haliclona koremella, Adocia neens, Callyspongia variabilis, Suberites axinelloides, Anthosigmella raromicrosclera, Epipolasis kushimotoensis, Acanthella insignia, and Spongosorites salimonensis.

  • Ten new species of two families (Suberitidae and Polymastidae) are described from Korea. Six new species in Suberitidae: Plicatellopsis ramosa n. sp., Pseudosuberites anheungensis n. sp. P. youngilensis n. sp., Suberites hwasunensis n. sp., S. chujaensis n. sp. and S. rugosa n. sp. are compared with other similar reported species. All new species differ from previously reported species in morphology, texture, color, skeletal structure, and spicule type. Four new species in Polymastidae: Polymastia fistula n. sp., P. sasuensis n. sp., P. viridis n. sp., and Weberella haengwonensis n. sp. are different from previously reported species in the growth form of papillaes and fistules, color and spicule types. For example, Weberella haengwonensis is similar to Weberella verrucosa in shape, but differs based on surface papillaes and spicule sizes.

  • Variations in the species composition, biomass and size distribution of fisheries resources in the Uljin marine ranching area were investigated using trammel nets at two stations (artificial reef and natural rocky area) from 2009 to 2010. During the survey, a total of 74 species were sampled with a mean density of 132 ind./net and mean biomass of 21.56 kg/net. In the natural rocky area, a total of 45 species were sampled at a mean density of 202 ind./net and mean biomass of 28.81 kg/net, while in the artificial reef area, samples included a total of 56 species, with means of 62 ind./net and 14.30 kg/net. The dominant species, comprising over 3% of the total number of individuals, were Suberites ficus (30.8%), Ovalipes punctatus (19.2%), Paralichthys olivaceus (11.7%), Pleuronectes herzensteini (4.7%), Kareius bicoloratus (3.5%), Pseudopleuronectes yokohamae (3.5%) and Eopsetta grigorjewi (3.0%). The dominant species, in terms of biomass, comprising over 5% of the total biomass, were P. olivaceus (22.1%), S. ficus (18.7%), O. punctatus (7.2%), Hexagrammos otakii (6.6%), P. yokohamae (5.7%), K. bicoloratus and P. herzensteini (5.3%). A cluster analysis and non-metric multidimensional scaling (nMDS) analysis based on the Bray-Curtis similarity of fourth root transformed data for number of species and individuals, was divided into two groups: the artificial reef area (group A) and the natural rocky area (group B).
