Potential Association between Insulin-like Growth Factor-1
Receptor Activity and Surf Clam Spisula sachalinensis Larvae Survival

Youn Hee Choi and Taek Jeong Nam*

We investigated the relationship between viability and IGF-1 receptor (IGF-1R) activity in D-shaped and umbo larvae of the surf clam Spisula sachalinensis after treatment with vitrification solution (VS) or freezing. In a toxicity assay, VS1, containing 5 M dimethyl sulfoxide (DMSO), was very harmful to D-shaped and umbo larvae. However, VS2, containing 5 M ethylene glycol (EG), was not harmful to either larval stage. Although VS2 had a promising toxicity test outcome, none of the lar...
A New Abundance Estimate for the Finless Porpoise
Neophocaena asiaeorientalis on the West Coast of Korea:
An Indication of Population Decline

Kyum Joon Park*, Hawsun Sohn, Yong Rock An, Hyun Woo Kim and Doo Hae An

The west coast of Korea is the largest habitat for finless porpoises, with approximately 36,000 individuals reported in 2005 (Park et al., 2007). To date, there have been no subsequent finless porpoise population estimates. However, in recent bycatches, finless porpoises accounted for the highest proportion of all cetaceans and have been reported to be most frequently caught on the west coast of Korea (Kim et al., 2013). The present study, conducted in 2011, enumerated finless porpois...
Taxonomic review of the Korean lumpsucker “Do-chi” reported previously as Eumicrotremus orbis (Pisces: Cyclopteridae) based on morphological and molecular characters
Soo Jeong Lee1, Seong Yong Kim2, Dae Yeon Moon2 and Jin-Koo Kim1

The Korean lumpsucker, “Do-chi”, reported previously as Eumicrotremus orbis, was reinvestigated based on specimens collected from Korea, Japan, and the USA. Morphological and genetic analyses showed that “Do-chi” corresponds to Eumicrotremus taranetzi and clearly differs from E. orbis. Eumicrotremus taranetzi is readily distinguishable from E. orbis by its large, high spiny tubercles with weak, small or no prickles (small, low spiny tubercles with distinct prickles in E. orbis) and 3-...
Revision of the Scientific Name for “Min-be-do-ra-chi”
Identified Previously as Zoarchias glaber in Korea

Hyuck Joon Kwun1 and Jin-Koo Kim2

The Korean stichaeid fish “Min-be-do-ra-chi”, reported previously as Zoarchias glaber, is reviewed taxonomically and described based on a single specimen collected from Jeju Island, Korea. “Min-be-do-ra-chi” was identified as Z. major by the following morphological characteristics: U-shaped markings on the dorsal and anal fins, 31 dorsal fin spines, 78 dorsal fin soft rays, 87 anal fin soft rays, and 109 vertebrae. In contrast, Z. glaber has triangular markings on the dorsal and anal ...
SCUBA Observations of Spawning in Hexagrammos agrammus off the Tongyeong Coast, Korea
Yong-Deuk Lee, Seung-Hwan Lee and Woo-Seok Gwak*

We used direct diving observations to determine the seasonality and other characteristics of spawning in the greenling Hexagrammos agrammus off the coast of Tongyeong. Eleven spawning grounds were identified between November 11, 2013 and January 25, 2014. The fertilized eggs of H. agrammus were assigned to developmental stages I, II, III, and IV. Based on this classification, we showed that the spawning season extended from the end of October to mid-January. H. agrammus used diverse s...
Characteristics and Pathogenicity for Eel Anguilla japonica of Vibrio vulnificus Isolated from Oyster, Sediment and
Seawater of Korea Coast

Myoung Sug Kim1, Sung Hee Jung1, Suhee Hong2 and Hyun Do Jeong3

Biotyping of Vibrio vulnificus strains isolated from marine environments along the south coast of Korea showed that the majority of the isolates (94.7%) belonged to biotype 1 and the remaining isolates (5.3%) belonged to biotype 2. Analysis of 16S rRNA V. vulnificus strains isolated from marine environments using a multiplex polymerase chain reaction (PCR) revealed that 78.7% were type A and 21.3% were type B. Random amplified polymorphic DNA (RAPD) was used to analyze the genomic dif...
Effects of Dietary Supplementation with Immunogen® on the Growth, Hematology and Gut Microbiota of Fingerling Common Carp Cyprinus carpio (Linnaeus)
A. Keramat Amirkolaie1 and B. Rostami2

We studied the effects of the proprietary prebiotic Immunogen® on the growth, hematology and gut microbiota of common carp fingerlings. A basal diet was formulated using common feed ingredients and supplemented with Immunogen® at concentrations of 0, 5, 10, 20 and 40 g kg-1, each of which was tested experimentally on replicated groups of fish. The trials ran for 8 weeks. Common carp fingerlings with an initial weight of 4.82 ± 0.05 g were randomly distributed among the experimental ta...
Postprandial Ammonia Excretion and Oxygen Consumption Rates in Olive Flounder Paralichthys olivaceus Fed Two
Different Feed Types According to Water Temperature

Jinhwan Lee

Postprandial ammonia excretion and oxygen consumption in olive flounder Paralichthys olivaceus fed two different feed types,
moist pellet (MP) and expanded pellet (EP) diets, to satiation were determined at 12°C, 15°C, 20°C, and 25°C for 48 h. The ammonia
excretion and oxygen consumption rates increased with increasing water temperature. However, the postprandial times for
the maximum rates of ammonia excretion and oxygen consumption were shortened from 12 h to 6 h after feed...
Effects of Dietary Supplementation of Two types of propolis
on growth performance, feed utilization, innate immunity
and disease resistance of olive flounder Paralichthys olivaceus

G. L. B. E. Gunathilaka1, Yong-Kap Hur2, Se-Jin Lim3 and Kyeong-Jun Lee 1*

We investigated the effects of dietary supplementation of two types (powder or liquid) of propolis on innate immunity and disease
resistance of olive flounder Paralichthys olivaceus against Edwerdsiella tarda. A total of 600 fish averaging 30 g were randomly
distributed into 24 tanks in groups of 25. Three tanks were assigned to each of eight experimental diets: 0 (Control), 0.25, 0.5,
0.75 and 1 % propolis in powder form and 0.25, 0.5 and 1 % propolis in liquid form (PP0.25,...
Effect of Dietary Lipid Sources on Body Fatty Acid Composition of Chinese Longsnout Catfish Leiocassis longirostris Günther
Jin Choi1 and Sang-Min Lee2*

This study investigated the effects of dietary lipid sources on growth and fatty acid composition of juvenile Chinese longsnout catfish. Triplicate groups of fish (initial average weight, 3.8 g) were fed four diets containing either fish oil (FO), soybean oil (SO), linseed oil (LO) and lauric acid (LA) for 10 weeks. There were no differences among the groups in body weight, feed intake, feed efficiency, protein efficiency ratio, and body proximate composition of fish fed the diets con...
Degradation Characteristics of A Novel Multi-Enzyme-
Possessing Bacillus licheniformis TK3-Y Strain for the
Treatment of High-Salinity Fisheries Waste Containing Green Seaweed

Kyeong Hwan Kang and Joong Kyun Kim*

To reutilize fisheries waste, a bacterial strain was isolated from a coastal area located in Busan. It was identified as Bacillus licheniformis TK3-Y. Using plate assay and 500-mL flask experiments, we found that the isolate simultaneously possessed cellulolytic, proteolytic, and lipolytic activities with salt tolerance. 10% (v/v) inoculums, were used to examine the biodegradation characteristics of the TK3-Y strain on carboxymethylcellulose, skim milk, and olive oil media. The op...
Investigation of Antimicrobial, Antioxidant and Hemolytic Activity of Water-soluble Extract of Mottled Anemone
Urticina crassicornis

Ye Jin Lee, Chan-Hee Kim, Hye Young Oh, Hye-Jin Go and Nam Gyu Park*
Sea anemone (phylum Cnidarian) has been recognized as a new source of marine bioactive compounds due to the growth of marine bioprospecting. Studies of bioactive compounds in cnidarians have focused mainly on antitumor compounds, such as toxins in aqueous extracts and terpenoids in organic solvent extracts. In this study, we evaluated the biological activities of five water extracts of tissue of the mottled anemone Urticina crassicornis. Most extracts exhibited broad-spectrum antimicr...
