In August 2019, we have conducted qualitative samplings at low tide in exposed intertidal zones and tide pools of 14 uninhabited islands around Jindo Island, located on the southwest coast of Korea. The main purpose of the survey was to make a species inventory of the organisms that inhabited the study area. In addition, the dominant species with high density in the area were also examined through quantitative survey. Rocky substrate and tidal pools were developed in all uninhabited islands. Taponies and cracks on the surface of substrate were also deveploped, which provided living habitats for marine benthic invertebrates. A total of 52 species were collected, consisting of six phyla, 11 classes, 18 orders, 34 families and 52 species, and the molluscs were the most dominant faunal group among them, with 32 species (61.5%), 3 classes, 8 orders and 16 families. The arthropods formed the second dominant faunal group, amounting to 9 species (17.3%), 2 classes, 3 orders and 9 families. In addition, Porifera, Cnidaria, Bryozoa and Echinodermata in the area numbered between one and three species, respectively. The greatest number of species were found on Dureukdo island, with 27 species that included 20 species of molluscs, and seven other islands such as Donseo island featured more than 20 species. The rest of the remaining uninhabited islands featured more than 10 species, with those found on Shineudo island being the lowest in number (14 species). The ones that were found in all the sampling areas were Reishia clavigera and Ligia exotica. In addition, Echinolittorina radiata was found to be the dominant species in 10 areas including Sososongdo island. The dominant species found in other areas were as follows: Tetraclita japonica in 9 islands including Haesuyeo(Gochiyeodo) island, Pollicipes mitella in 8 islands including Judo island, Mytilisepta virgata in 5 islands including Donseo island, Lottia dorsuosa in 3 islands including Bukdo(Siruseum) island, Littoraria brevicula in 2 islands including Shineudo island, Nerita japonica in Donseo island, Cellana grata in Shindo island, and Omphalius rusticus in Judo islands. Comparative analysis of marine invertebrates on the rocky intertidal area between the study area and adjacent southwest coastal area showed that the two areas featured similar type of dominant species, zonal distribution pattern, and total number of species. However, type of dominant species and total number of species were found to be slightly different in Shinan and Wando areas due to sampling methods and sediment environment. These results indicated that the dominant species and distribution pattern of macroinvertebrate in rocky area of Jindo uninhabited island were similar to those of other islands in southwest coast of Korea, that can be useful in establishing management policies for uninhabited islands regarding the monitoring of changes in the coastal marine ecosystem and environment.

Jeong Bo-Young,Choi Byeong-Dae,Moon Soo-Kyung,Lee Jong-Soo,Jeong Woo-Geon The Korean Society of Fisheries and Aquatic Scienc 1998 Fisheries and Aquatic Sciences Vol.1 No.2

Fatty acid compositions of 35 species of marine invertebrates (13 species of Bivalvia, 10 species of Gastropoda, 4 species of Cephalopoda, 4 species of Crustacea, 2 species of Ascidacea, 2 species of Holothuroidea) were studied using gas-liquid chromatography. Total lipids in all samples were very low, ranging from $0.24\%$ to $1.96\%$. The prominent fatty acids were 16:0, 20:5 (n-3), 22:6 (n-3), 18:0, 16:1 (n-7), 20:4 (n-6), 18:1 (n-9) and 18:1 (n-7) in the majority of marine invertebrates. Polyunsaturated fatty acid (PUFA) was the richest fatty acid group in all invertebrates, accounting for $55.3\pm6.70\%$ of total fatty acids (TFA), followed by saturated $(26.2\pm4.33\%)$ and monounsaturated fatty acid $(18.5\pm5.87\% )$. No correlation was found between total lipid content and each fatty acid group. Cephalopoda contained the highest level of n-3 PUFA $(54.6\pm5.17\%)$, while Holothuroidea and Gastropoda contained the lowest level of n-3 PUFA, accounting for $26.5\pm4.44\%$ and $28.4\pm4.04\%$, respectively. Bivalvia and Ascidacea are plankton feeders, which were rich in 20:5 (n-3) and 22:6 (n-3). Carnivorous species of Cephalopoda were prominently rich in 22:6 (n-3), ranging from $26.7\%$ to $46.1\%$ of the TFA. However, some species of Gastropoda are seaweed feeder (herbivorous), which contained high level of 20:4 (n-6) compared to plankton feeder and carnivorous species. In addition, blue and red colored sea cucumbers, and turban shells with and without apophyses belong to the same species, but they live in different habitats. These organisms were found to have different fatty acid compositions. Therefore, fatty acid compositions of these invertebrates might be affected by their different environments, particularly their diet.

ATP-binding cassette (ABC) proteins in aquatic invertebrates: Evolutionary significance and application in marine ecotoxicology

Jeong, C.B.,Kim, H.S.,Kang, H.M.,Lee, J.S. Elsevier/North Holland Biomedical Press 2017 Aquatic toxicology Vol.185 No.-

<P>The ATP-binding cassette (ABC) protein superfamily is known to play a fundamental role in biological processes and is highly conserved across animal taxa. The ABC proteins function as active transporters for multiple substrates across the cellular membrane by ATP hydrolysis. As this superfamily is derived from a common ancestor, ABC genes have evolved via lineage-specific duplications through the process of adaptation. In this review, we summarized information about the ABC gene families in aquatic invertebrates, considering their evolution and putative functions in defense mechanisms. Phylogenetic analysis was conducted to examine the evolutionary significance of ABC gene families in aquatic invertebrates. Particularly, a massive expansion of multixenobiotic resistance (MXR)-mediated efflux transporters was identified in the absence of the ABCG2 (BCRP) gene in Ecdysozoa and Platyzoa, suggesting that a loss of Abcg2 gene occurred sporadically in these species during divergence of Protostome to Lophotrochozoa. Furthermore, in aquatic invertebrates, the ecotoxicological significance of MXR is discussed while considering the role of MXR-mediated efflux transporters in response to various environmental pollutants.

Background: Marine invertebrates are well known as pivotal bioresources with bioactive substances such as anti-inflammatory sterols, antitumor terpenes, and antimicrobial peptides. However, there are few scientific reports on chemical compositions and bioactivities of marine invertebrates from the East Sea of South Korea. Methods: In this study, chemical compositions and biological activities were evaluated on both 70% EtOH and hot water extracts of 5 species of marine invertebrates (Crossaster papposus japonicus, Actinostola carlgreni, Stomphia coccinea, Actinostola sp., and Heliometra glacialis) collected from the East Sea of South Korea. The antioxidant activities were measured by ABTS radical scavenging assay. The cytotoxicity and anti-inflammatory activity were evaluated using MTT and Griess reagents. Moreover, the antibacterial effect was evaluated using paper disc assay and minimum inhibitory concentration (MIC) assay. Results: In the results of antioxidant activities, 70% EtOH extract of A. carlgreni showed the highest activity ($IC_{50}\;0.19{\pm}0.03mg/ml$) compared to other extracts. Moreover, 70% EtOH extract of A. carlgreni could significantly suppress the nitric oxide (NO) production in lipopolysaccharide-induced RAW 264.7. All extracts treated under $400{\mu}g/ml$ have no cytotoxic effects on RAW 264.7 macrophages. In the antibacterial test, both 70% EtOH extracts of C. papposus japonicus and H. glacialis showed a significant antibacterial effect on Staphylococcus aureus. The MIC values were evaluated at 256 and $512{\mu}g/ml$, respectively. Conclusions: These results suggested the bioactive potentials of marine invertebrates from the East Sea of South Korea in pharmaceutical and nutraceutical applications.

The Dokdo macrozoobenthos was represented by 578 species belonging to 243 families from 12 phyla, where four major phyla (or classes) collectively accounted for 86% to total. Mollusks, arthropods, and cnidarians were semi-equally occurred in intertidal and subtidal areas, while polychetes dominated the subtidal zone. The northern most region of Dokdo had the greatest biodiversity (173 species). The taxonomic distinctness analysis (delta+) indicated a close association between species by region, although the number of species varied greatly. About half of the species did not occur cross the locations (n=20), indicating strong habitat preferences of Dokdo macrofaunal assemblages. Overall, the diversity of Dokdo was greater than that of Ulleung Island (east coast), but comparable to that of the well-developed tidal flats in the western Korean waters, highlighting its status as a biodiversity hotspot.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Provided most up-to-dated numbers of marine invertebrates in Dokdo and Ulleung Island </LI> <LI> Characterized species composition and regional distribution by geography and habitats </LI> <LI> Assessed general ecological quality of marine benthic invertebrates in remote islands </LI> <LI> Characterized Dokdo invertebrates by comparison to those in east and west coast of Korea </LI> </UL> </P>

한국 연안산 해산 무척추동물의 미네랄 함량과 영양평가

목종수,이두석,심길보,윤호동 한국수산과학회 2009 한국수산과학회지 Vol.42 No.2

To measure the mineral contents of marine invertebrates, we collected 239 individuals from 52 species from the east (Pohang), west (Gunsan), and south (Tongyeong) coasts of Korea: 34 species of molluscan shellfish (Gastropoda and Bivalvia), 6 species of Cephalopoda, 8 species of Crustacea, and 4 other species. The mean contents of the macro mineral in the 100g edible portion of molluscan shellfishwere high in the oder of Na (355.1mg), P (128.1mg), K (110.8mg), Mg (83.8mg) and Ca (57.5mg). And the mean contents of the micro mineral in the molluscan shellfish were high in the oder of Fe (41.12μg/g), Zn (30.48μg/g), Mn (3.81μg/g), Cu (3.49μg/g) and Ni (0.35μg/g). We could not observe clear regional variation in the mineral content of the molluscan shellfish species. The mean contents of the macro mineral in the 100g edible portion of other marine invertebrates (Cephalopoda, Crustacea, etc.) were high in the oder of Na (400.7mg), P (145.1mg), K (105.0mg), Mg (63.2mg) and Ca (49.0mg). And the mean contents of the micro mineral in other marine invertebrateswere high in the oder of Zn (24.4μg/g), Fe (13.8μg/g), Cu (4.88μg/g), Mn (2.14μg/g) and Ni (0.12μg/g). The daily average intakes of the macro mineralthrough fisheries products consisted of P (125.9mg), Na (119.3mg), K (101.8mg), Ca (31.0mg), Mg (27.6mg). And the daily average intakes of the micro mineralthrough fisheries products consisted of Zn (0.92mg), Fe (0.68mg), Cu (0.12mg) and Mn (0.07mg). The respective intakes of the minerals (P, Mg, Na, Ca, K) from fish were about 18.0, 7.9, 8.0, 4.4 and 2.2% of the dietary reference intakes for Koreans (KDRIs) set by the Korean Nutrition Society. And the respective intakes of micro mineral (Cu, Zn, Fe, Mn) from fish were about 14.6, 9.2, 6.7, and 2.1% of the dietary reference intakes for Koreans (KDRIs). Therefore, fisheries products play a very important role as a source of mineral.
