The toxicity of five species of puffer fish, Arothron firmamentum (Byeolbok), Lagocephalus gloveri (Heukmilbok), L. wheeleri (Eunmilbok), L. inermis (Minmilbok) and L. lunaris (Milbok), collected from fish markets in Korea, was determined using a mouse bioassay. In A. firmamentum, the proportion of toxic specimens containing >10 MU/g was 87.5% in the ovaries, and 10.0% in the skin; no toxicity was detected in the muscle, fin, liver, intestine and gallbladder using the mouse bioassay. The highest toxin levels were found to be 87 MU/g in the ovaries, and 13 MU/g in the skin. Toxic specimens containing >10 MU/g were not detected from samples taken from any of the organs in L. wheeleri and L. inermis. In L. gloveri, most specimens were found to be non-toxic, but toxin levels of 11-72 MU/g were detected from within the skin, fins, and intestines in one specimen. In L. lunaris, the proportion of toxic specimens was 50.0% in the ovaries, and 7.1% in the gallbladder; no toxicity was detected in the other organs by the mouse bioassay. The highest toxin levels were 75 MU/g in the ovaries, and 14 MU/g in the gallbladder. Therefore, the toxicities of edible muscle and skin in the five species of puffer fish marketed in Korea were found to be within acceptable levels for human consumption.

To measure the mineral content of fishes, we collected 177 individuals from 53 fish species from the east (Pohang), west (Gunsan), and south (Tongyeong) coasts of Korea. The mean content of the macro mineral in a 100 g sample taken from the edible portion of each fish was (in descending order): P(207.4 mg), K(169.7 mg), Na(101.6 mg), Ca(44.4 mg), and Mg(30.4 mg). In comparison, the mean content of micro mineral in the fishes was (in descending order): Zn (
), Fe (
), Cu (
), Mn (
), and Ni (
). We could not observe clear regional variation in the mineral content of fish species. With regard to minerals considered essential for humans, the amount of Ca per sample (100 g) was the highest in the Scyliorhinus torazame (465.4 mg), and than followed by Ammodytes personatus (338.0 mg), Dasyatis akajei (267.4 mg), Raja kenojei (248.1 mg), Conger myriaster (174.1 mg), Clupanodon punctatus (86.8 mg), Muraenesox cinereus (81.2 mg), and Engraulis japonica (70.4 mg). The daily average intake of the mineral through the fishes consisted of P (100.6 mg), K (82.3 mg), Na (49.3 mg), Mg (14.8 mg), Zn (0.44 mg), Fe (0.24 mg), Cu (0.04 mg) and Mn (0.02 mg). The respective intakes of macro mineral (P, Mg, Na, Ca, K) from the fishes were about 14.4, 4.2, 3.3, 3.1 and 1.8% of the dietary reference intakes for Koreans (KDRIs) set by the Korean Nutrition Society. In comparison, the respective intakes of micro mineral (Cu, Zn, Fe, Mn) from the fishes were about 4.6, 4.4, 2.4, and 0.6% of the KDRIs.

Vibrio parahaemolyticus species, which cause acute gastroenteritis in humans, were isolated from farmed fish and seawater and their antimicrobial-resistance pattern and factor were investigated. They exhibited the highest resistance to ampicillin (88.9%), followed by trimethoprim (51.9%) and rifampin (22.2%). The relatively high resistance to trimethoprim was unexpected because trimethoprim was not commonly used in fish farming in Korea. R plasmid related resistance was identified by the treatment of novobiocin (7 ug/mL) and it was named as pVPBW1. A putative trimethoprim resistance gene in 2.0 kb fragment of pVPBW1 was also confirmed.

We investigated the effect of a green seaweed Capsosiphon fulvescens extract (CFE) on the serum, liver tissue, and fecal cholesterol levels in rats. Male Sprague-Dawley rats (four weeks old) were given on of three diets for four weeks: basal, high cholesterol, and CFE, The total serum and liver tissue cholesterol levels in the CFE group were significantly decreased compared to those in the cholesterol group. The CFE group showed increased amounts of feces, total fecal bile acid and dietary fiber as compared to basal and cholesterol group. Hematoxylin and eosin staining revealed fat droplets in the livers of the rats in the cholesterol group; however, a decreased number of droplets was observed in the rats fed the CFE diet. Our results suggest that CFE supplementation may improve lipid metabolism, by controling serum and liver tissue cholesterol levels, and by increasing the total amounts of bile acid, dietary fiber and cholesterol excretion in feces.

Korean Journal of Fisheries and Aquatic Sciences, volume 41, issue 5, 2008, Pages 337~342
DOI : 10.5657/kfas.2008.41.5.337
Eight quality standards of the brown seaweed, Undaria pinnatifida were designed and evaluated with dry products collected from aquacultured and wild areas. Contents of n-3 fatty acids (stearidonic acid and eicosapentaenoic acid), anti-edema activity, and total carbohydrate were measured as functional criteria. Total bacteria and molds were counted for safety conditions. Amounts of a brown pigment fucoxanthin, debris, and moisture were measured to evaluate the visible status of the products. When the seaweeds were tested in 1 g dry weight basis, they showed n-3 fatty acids in the range of approximately 0.2-2.8 mg, total carbohydrate of 0.39-0.71 g, total bacteria of
cells, mold of
cells, fucoxanthin of 0.4-1.5 mg, and debris of 10-24 mg. Anti-edema activity was 0.03-0.47 AU at 40 mg/mL extract. Moisture content was 11.4-12.6%.

DOI : 10.5657/kfas.2008.41.5.343
This study determined the optimum feeding frequency for the growth of juvenile cherry salmon (Oncorhynchus masou). Triplicate groups of fish (initial mean weight 19.1 g) were fed extruded pellets at four feeding frequencies for 50 days: once every 2 days, once a day, twice a day, and three times a day. The mean water temperature during the feeding trial was
. The survival of all groups was 100%. The final fork length of fish fed twice a day was significantly greater than that of the other groups (P<0.05). The weight gain of fish fed two and three times daily was significantly greater than that of fish fed once a day or every 2 days (P<0.05). The daily feed intake increased significantly with feeding frequency (P<0.05), but there was no significant difference in the weight gain of fish fed two or three times a day. The feed efficiency of fish fed once every 2 days was highest (P<0.05), and the feed efficiency of fish fed two or three times a day was significantly higher than that of fish fed once a day (P<0.05). The results of this study indicated that the optimum feeding frequency for the growth of juvenile cherry salmon is twice a day, while the feeding efficiency of fish fed once every 2 days was best.

Yellow croaker (Larimichthys polyactis) is a major target species of large pair trawl fishery in the East China Sea. To standardize catch per unit effort (CPUE) of yellow croaker for the large pair trawl fishery, generalized linear model (GLM) was applied to evaluate and eliminate the influence of the explanatory factors (year, month, horse power and gross tonnage of vessel) on daily catches per boat collected and compiled by National Fisheries Research and Development Institute (NFRDI) from 1990 to 2007 at the fishery auction places of Busan, Masan and Incheon in Korea. Results of GLM showed that all of the factors significantly influenced on CPUE, explaining 36% of the total deviance. The standardized CPUE indicated that the abundance of yellow croaker in 2000`s was 1.7 times higher than the CPUE in 1990`s.

The fish species composition and variation in the Youngil Bay, East Sea of Korea, were investigated every month from January, 2001, to December, 2002, using gill nets for sample collection. A total of 63 fish species belonging to 31 families under 10 orders, and a total of 40 species belonging to 26 families under 8 orders, were identified in 2001 and 2002, respectively. Of these, the families Pleuronectidae (9 species), Scorpaenidae (8 species) and Cottidae (5 species) were dominant in 2001, whereas Pleuronectidae (4 species), Cottidae (3 species) and Hexagrammidae (3 species) were dominant in 2002. The number of species recovered was the highest in August, 2001 (34 species) and January and September, 2002 (14 species each), and lowest in May, 2001 (6 species) and December, 2002 (5 species). The principal component analysis for each year showed that fish species composition differed over time even within the same sample area. In addition, the relationship between PC scores and temperature showed a positive relationship in 2001, but a negative relationship in 2002.

The ichthyofauna of certain reservoirs in Pohang-si, Gyeongsangbuk-do, were studied during the period from October 7-19, 2005. During the study period, 9,480 individuals (ind.) belonging to 22 species, 17 genera, 8 families and 4 orders were collected. Of these, 11 species were cyprinidae fishes, and the dominant species was Pseudorasbora parva (relative abundance 47.14%). There were six Korean endemic species (289 ind., relative abundance 3.04%), including Squalidus chankaensis tsuchigae, Squalidus mulimaculatus, Hemiculter eigenmanni, Iksookimia yongdokensis and Coreoperca herzi, and the dominant Korean endemic species was Pseudobagrus brevicorpus (relative abundance 3.04%) collected in Hoehakji, Cheonggyeji, Ahnsimji and Mabukji. There were five introduced species. Three species, including Hemiculter eigenmanni, Pseudobagrus fulvidraco and Hypomesus nipponensis, were introduced from other native stream systems, and two species, including Carassius cuvieri and Lepomis macrochirus, originated in foreign countries. Of these, Lepomis macrochirus (l,521 ind., relative abundance 16.05%) was collected at the all reservoirs except at Gidongji. These results suggest that the exotic fishes in question have been widely dispersed within the reservoirs in Pohang-si.

Choi, Chang-Geun ;
Korean Journal of Fisheries and Aquatic Sciences, volume 41, issue 5, 2008, Pages 371~380
DOI : 10.5657/kfas.2008.41.5.371
This study elucidated the floral composition of marine algae and community structure at Hallyeo-haesang National Park, on the southern coast of Korea. In all, 89 species, comprising 10 green, 30 brown and 49 red algae, were identified. The dominant species in terms of importance value were Ulva pertusa, Colpomenia sinuosa, Undaria pinnatifida, Padina arborescens, Hizikia fusiformis, Sargassum sagamianum and Amphiroa dilatata. The vertical distribution of marine vegetation was characterized by Enteromorpha linza - Ulva pertusa - Gelidium divaricatum in the upper intertidal zone, Hizikia fusiformis - Sargassum thunbergii in the middle intertidal zone, and Amphiroa spp. - Hildenbrandtia rubra - Corallina pilulifera in the lower intertidal zone. Functional form group analysis showed that coarsely branched forms comprised 50.3% of the algal community, whereas thick leathery forms, sheet forms and filamentous forms comprised 11.9-13.1%. R/P, C/P and (R+C)/P values were 1.91, 0.74 and 2.64, respectively. A cluster analysis of species occurrence suggested that the number of marine algal species differed greatly among the sampling sites.

Induction of regeneration and maturation for the free-living gametophytes of Ecklonia cava Kjellman was conducted under various temperature, irradiance and photoperiod conditions. Culture conditions for female or male gametophyte fragments were 4 temperature (5, 10, 15 and
), 4 irradiance (5, 10, 20 and
) and 3 photoperiod (14:10, 12:12 and 10:14 h L:D). Female and male gametophyte fragments were maintained in active regeneration without reaching sexual maturity under
, 12:12h or 10:14h (L:D) and
, 14:10h (L:D), respectively. Sexual maturation of female and male gametophytes facilitated under
, 14:10h (L:D) and
, 10:14h (L:D), respectively. These results provide basic informations to control the regeneration or maturation of the free-living gametophytes for artificial seed production of E. cava.
Regional Characteristics of a Crackdown on Illegal Fisheries in Korean Waters
Kim, Hong-Eun ; Hong, Chul-Hoon ;
Korean Journal of Fisheries and Aquatic Sciences, volume 41, issue 5, 2008, Pages 389~398
DOI : 10.5657/kfas.2008.41.5.389
The regional characteristics of crackdown on illegal fisheries in Korea Waters are investigated using data from the Ministry of Maritime Affairs and Fisheries, local cities and Provincial governments, and the Korea Coast Guard from 1996 to 2006, focusing on the relationship between the crackdown on illegal fisheries, catches within the affected regions, and characteristics of similar crackdown in Chinese fishing vessels. Illegal fisheries in the South Sea were all strongly affected within each region, and a relationship between the crackdown and subsequent catches showed a relatively good correlation in the South Sea. As a monthly variation, a strong correlation appeared during the autumn season, but this strong correlation was not evident during the spring. This paper suggests that a relationship exists between the crackdown on illegal fisheries and subsequent catch rates, suggesting that an intensification of these efforts in the South Sea and the Yellow Sea, and attendant increases in manpower and equipment would result in a significant decrease in illegal fishing by Chinese fishing vessels from year to year.
Improvement of the Consultation Systems Governing Fishery Resource Management in the Development of Coastal Areas
Lee, Dae-In ; Eom, Ki-Hyuk ; Kim, Gui-Young ;
Korean Journal of Fisheries and Aquatic Sciences, volume 41, issue 5, 2008, Pages 399~404
DOI : 10.5657/kfas.2008.41.5.399
This paper proposes revisions in the law governing assessments of the environmental impact of marine projects. In particular, we suggest strengthening the consultative role of the Ministry for Food, Agriculture, Forestry and Fisheries (MIFAFF), the agency responsible for regulating coastal area utilization and development, in order to improve the system by which fishery resources are managed, thus preventing negative environmental impact. Moreover, such an improved impact assessment statement would include reasonable evaluations of the dispersion of pollutants, such as the suspended solids generated by construction projects, as well as of the dredging, dumping and sand mining involved in coastal area reclamation. Thus, public confidence in the latter would be increased by the development and implementation of standardized and consistent guidelines addressing environmental research, simulation processes and evaluations of data.
