At the first time in South Korea, the state of the art acoustic systems were mounted on the R/V Tamgu 21. The acoustic systems are an EK80 broadband echosounder (18, 38, 70, 120, 200 and 333 kHz) which has two beam modes such as continuous wave (narrowband) and frequency modulation (broadband), an ME70 multibeam echosounder (70-120 kHz), and a SH90 sonar (111.5-115.5 kHz). Acoustic data from broadband mode have a very short range resolution, a large detection range, a high signal to noise ratio, and a wide and consecutive frequency response. In ME70, each individual beam consisted in a multibeam plays a role as a spilt beam. The first trial of the cutting edge acoustic system installed on the R/V Tamgu 21 was conducted from 15 Feb to 29 Feb 2016 in East Sea, South Sea and East China Sea. The properties of the acoustic systems were elucidated and exploratory results from three systems were exhibited. Lastly, issues which should be considered and future research plan are mentioned.

Original Article : The Growth, Innate Immunity and Protection against H2O2-Induced Oxidative Damage of a Chitosan-Coated Diet in the Olive Flounder Paralichthys olivaceus

We demonstrate enhanced growth, innate immunity and protection against hydrogen peroxide (H2O2)induced protein oxidation and cellular DNA damage in olive flounder Paralichthys olivaceus fed a chitosan-coated moist pallet (MP) diet. A chitosanbased biopolymer coated MP as the experimental diet and a non-coated MP (control) was fed to olive flounder fish. Growth, including the average weight gain (g/fish), weight gain (%) and feed intake (g) of the fish group fed a chitosan-coated MP diet increased significantly. The survival rate was reported as 100% throughout the experimental period. Immunological parameters indicated higher mucus lysozyme activity and significantly higher fish skin mucus total protein content was observed in fish fed the chitosan-coated MP diet compared to the control. A blood plasma analysis revealed attenuation of cellular DNA and protein oxidative damage caused by H2O2-induced oxidative stress in the fish fed the chitosan-coated MP diet compared to the control group. Moreover, blood serum biochemical analysis revealed health-promoting effects, including significantly higher hemoglobin and total cholesterol levels in the fish fed the chitosan-coated MP diet compared to the control group. In conclusion, growth, innate immunity and protection against oxidative stresses were improved by feeding of the chitosan-coated MP diet to olive flounder reared in aquaculture

Original Articles : Distillers Dried Grain from Makgeolli By-product Is Useful as a Dietary Ingredient for Growth of Juvenile Sea Cucumber Apostichopus japonicus

( Jin Choi ), ( Md Mostafizur Rahman ), ( Sang Min Lee ) 한국수산과학회(구 한국수산학회) 2013 Fisheries and Aquatic Sciences Vol.16 No.4

We tested the effects of various distillers dried grains (DDGs) in a formulated diet on growth and body composition of juvenile sea cucumber Apostichopus japonicus. DDG is a solid residue obtained by filtering an aqueous mixture of fermented rice with Aspergillus oryzae and yeasts. Six isonitrogenous and isocaloric diets (DDG0, DDG-G, DDG-C, DDG-K, DDG-W, and DDG-P) were formulated to contain 20% DDG obtained from different Makgeolli factories. Juvenile sea cucumber (average weight, 2.1 ± 0.02g) were randomly distributed in eighteen 50-L rectangular plastic tanks (40 L of water each) in a seawater flow-through system at a density of 50 juveniles/tank. Three replicate groups of sea cucumber were fed each of the six experimental diets at a feeding rate of 5% body weight per day for 22 weeks. At the end of the feeding experiment, survival and weight gain of the juvenile sea cucumber were not affected by the type of dietary DDG (P > 0.05), and the proximate and amino acid compositions of the whole body were not affected by dietary DDG diets (P > 0.05). These results indicate that rice-based DDG is a potential dietary ingredient that could be used at dietary concentrations of up to 20% for growth of juvenile sea cucumber.

Original Articles : Genomic Organization, Tissue Distribution and Developmental Expression of Glyceraldehyde 3-Phosphate Dehydrogenase Isoforms in Mud Loach Misgurnus mizolepis

( Sang Yoon Lee ), ( Dong Soo Kim ), ( Yoon Kwon Nam ) 한국수산과학회(구 한국수산학회) 2013 Fisheries and Aquatic Sciences Vol.16 No.4

The genomic organization, tissue distribution, and developmental expression of two paralogous GAPDH isoforms were characterized in the mud loach Misgurnus mizolepis (Cypriniformes). The mud loach gapdh isoform genes (mlgapdh-1 and mlgapdh-2)had different exon-intron organizations: 12 exons in mlgapdh-1 (spanning to 4.88 kb) and 11 in mlgapdh-2 (11.78 kb), including a non-translated exon 1 in each isoform. Southern blot hybridization suggested that the mud loach might possess the two copies of mlgapdh-1 and a single copy of mlgapdh-2. The mlgapdh-1 transcript levels are high in tissues requiring high energy flow, such as skeletal muscle and heart, whereas mlgapdh-2 is expressed abundantly in the brain. Both isoforms are differentially regulated during embryonic and larval development, during which their expression is upregulated with the progress of development. Lipopolysaccharide challenge preferentially induced mlgapdh-2 transcripts in the liver. Therefore, the two isoforms have diversifiedfunctionally; mlgapdh-1 is associated more closely with energy metabolism, while mlgapdh-2 is related more to stress/immune responses, in the mud loach.
