Two experiments were conducted to investigate the utilization of various types of fish meal as dietary protein sources in Korean rockfish (Sebastes schlegeli). In the first experiment, averaging 5.7 g fish were divided into two groups and fed one of diets containing
steam-dried white fish meal (SWFM) or
brown fish meal (BFM) for 45 days. Weight gain and feed efficiency from fish fed SWFM were significantly (P<0.05) higher than those from fish fed BFM diet. However, daily feed intake, protein retention and lipid retention were not influenced by the two different diets. In the second experiment, averaging 86.6 g fish were divided into six groups and fed one of diets containing
flame-dried white fish meal (FWFM),
hydrolyzed fish protein (HFP) for 21 weeks. No significant differences were found among fish fed the six different diets in weight gain, feed efficiency, condition factor, whole body composition, and relative liver weight. Results of the present studies indicated that fish size should be considered in selecting feed ingredients and also feed cost could be lowered by replacing SWFM with FWFM or BFM in growing Korean rockfish diet.

Forecasts of the monthly catches of anchovy in Korea were carried out by the seasonal Autoregressive Integrated Moving Average (ARIMA) model and spectral analysis. The seasonal ARIMA model is as follows:
is a backward shift operator, that is,
term at month t, which is to forecast 24 months ahead the anchovy catches in Korea. The prediction error by the Box-Cox transformation on monthly anchovy catches in Korea was less than that by the logarithmic transformation. The equation of the Box-Cox transformation was
. Forecasts of the monthly anchovy catches for
, which were compared with the actual catches, had an absolute percentage error (APE) range of
. Total observed annual catches in 1991 and 1992 were 170,293 M/T and 168,234 M/T respectively, while the predicted catches were 148,201 M/T and 148,834 M/T
. The spectrum analysis of the monthly catches of anchovy showed some dominant fluctuations in the periods of 2.2, 6.1, 10.2 12.0 and 14.7 months. The spectrum analysis was also useful for selecting the ARIMA model.

Insulin-like growth factor-1 (IGF-I) is a mitogenic peptide with molecular mass of 7kDa. It is produced mainly in the liver and has important functions in the regulation of development and somatic growth. Recently, several investigations were undertaken to examine the biological actions and structures of IGF-I in fish. In this study, the serum levels of IGF-I were estimated from flounder, Parlichthys oilvaceus, before, during and after fasting, and the levels were accounted for 47 ng/ml, 40 ng/ml and 45 ng/ml, respectively. These results suggest that food deprivation primarily reduces IGF-I level in the blood.

Korean Journal of Fisheries and Aquatic Sciences, volume 29, issue 2, 1996, Pages 157~164
Dry weight and body fluid osmolarity of embryo, and maternal ovarian fluid and the ovarian inner tissue of the viviparous teleost, Ditrema temmincki, changed considerably during the gestation period. After the complete absorption of the egg yolk, average dry weight of the embryo increased to 373.76 mg, and the range of total length (TL) was from 6.0 to 60.0 mm. Osmolarity of the embryonic body fluid was 796,8 mOsmol/kg with TL 64.0 mm right before parturition. Ovarian outer membrane started to swelling clearly after fertilization, and maximized in March. The swelling of ovigerous folds was maximized in late April. Expansion of blood vessels and increase of hemocytes reached to their maximum right before parturition. The results of this study indicated that these changes are related to the nutritional and environmental adaptation of both the embryo and the maternal body during the gestation period.

LEE Jong-Soo ;
Korean Journal of Fisheries and Aquatic Sciences, volume 29, issue 2, 1996, Pages 165~173
Large amounts (300 grams) of natural red tide plankton, Cochlodinium polykrikoides, was collected at the Yokji island coastal waters, Kyeongnam, Korea, on October, 1993. Using the bioassay systems, bioactive materials were screened from methanol extracts of C. polykrikoides. Live C. polykrykoides was toxic to fishes, however, the water soluble and chloroform soluble fraction of their methanol extracts did not shown ichthyotoxicity (5 mg/ml), and toxicity to mice (50 mg, i.p,). These fractions did not show any peaks corresponding to paralytic shellfish toxins or diarryhetic shellfish toxins on the fluorometric HPIC chromatograms. Neither fractions did not show antibiotic activities by paper disk (10 mg/disc) test and chloroform soluble fraction showed only
growth inhibition activity on the Lymphoid P-388 at the concentration of
. Hemolytic activity was detected by both fractions. Fatty acid analysis by GC, GC/MS and proton NMR showed that the chloroform soluble fraction composed of
of DHA (dorosahexaenoic acid) and
of IPA (eicosapentaenoic acid) as the hemolytic components.

Damage assessment based on in situ surveys for oil spills in marine environment is limited by fundamental difficulties as well as tremendous expenses. Except for intertidal zones, the damage is not preserved well. Also such surveys are usually confined to adult organisms. To overcome these limitations a computer model, NRDAM/CME, was developed in the case of USA (Reed et al., 1989), where an acute toxicity data base was used to assess indirect damages through food webs and loss due to recruitment as well as adult losses. In the present study damage assessment of natural biological resources for hypothetical oil spills is attempted using a computer model for hypothetical spills of Bunker C and heavy crude oil. In the model, the logical structure of NRDAM/CME was adopted, and biomass and productivity database were compiled for the Korean waters. The results showed that the damage increased in a nonlinear fashion as the spill amount increased. The magnitude of the damage depended upon the chemical properties of oil viscosity and solubility in particular, which implies that usage of oil dispersant might increase the damage by dispersing oil. The results also indicate that long term damage due to recruitment loss could be greater than short term damage.

Age growth and spawning period of Enedrias nebulosus were estimated based on otoliths taken from a total of 255 fish samples of E. nebulosus, which were caught in the costal waters of
near Pusan from November 1990 to October 1991. Marginal increment analysis indicates that annuli in E. nebulosus are formed in December. Spawning period was estimated to be November to January, with a peak in December. The von Bertalanffy growth equations were expressed as follows:
, is total length in cm,
, is total weight in g and t is age in year.

The proportion of log-associated school catches by Korean tuna purse seiners in the western Pacific has shown a declining trend until recent years. During the period
, log-associated school catches contributed
to the total Korean tuna purse seine catch, representing quite a low level compared to the early phase of the purse seine fishery. Species compositions of both log-associated and free-school catches showed that skipjack, Katswonus pelamis, was dominant species and yellowfin, Thunnus albacares, followed, with the small amount of bigeye tunas, T. obesus, Yellowfin proportion was higher in free-school catches than in log-associated school catches. Log-associated school catches monitored during the scientific observation period were made of
bigeye tunas, indicating the low skipjack and high yellowfin proportion compared with historical fisheries data based on logbooks. A total of 11 by-catch species were identified, of which sharks occurred together with tunas in all sets and yellowtail kingfish was the most abundant by-catch species. From the length distribution it was found that small yellowfin less than 70 cm mainly distributed around floating objects.

Korean Journal of Fisheries and Aquatic Sciences, volume 29, issue 2, 1996, Pages 208~229
Comprative osteology of the chum salmon Oncorhynchus keta, masu salmon O. masou and rainbow trout O. mykiss in Korea was studied. As a result, it was found that there were some differences in the structural features of the cranium and visceral skeleton among the species. Interspecific differencies in glossohyal, supraethmoid, parasphenoid and vomer were distinctive for the species. Chum salmon could be distinguished easily by some characters on form of glossohyal which is thin, long and sharp in shape. It has triangle shape supraethmoid while other two species have oval shape one. The shape of parasphenoid, preopercle, hyomandibular and the number of epurals were evaluated as new taxonomic criteria for the salmons.

Vertical profiles of
were measured for the upper 100 m of water column at six stations in the middle region of the Korean East Sea during March 1993. The distribution patterns of these radionuclides with the water mass and controlling factors on their distributions were also discussed.
activities were generally high at surface water and gradually decrease with depth. Vertical profiles of
were relatively homogeneous except for at station E3, where chlorophyll-a concentration was the highest and
activity in the upper 30 m was lower than below 50 m. The
activities relative to its parent
at all stations were deficient at the upper 30 m, but were excess or nearly equilibrated values below 50 m. The magnitude of
deficiency was relatively high at station E3 and E6, where strong thermocline occured. However,
activities showed strong excess in the upper 100 m of all stations, compared with its parent
. The residence time of
ranged from 1.0 to 7.8 years, and was relatively short at station E3 and E6. The data obtained at the upper 50 m water column during
, also showed that removal rate constant of
and inventories of chlorophyll-a was negatively related. This indicates that the primary production plays an important role in controlling the distributions of
at the upper water column of the Korean last Sea in spring. While, inventories of excess
was generally decreasing with increasing density difference between 50 m and 100 m, suggesting that
concentrations in the upper water column were controlled by stability of water column.

To develop a natural antioxidative peptide, the gelatin was extracted from fish (Yellowfin sole) skin by hot
extraction method and hydrolyzed with Alcalase, pronase and collagenase through a continuous 3-step membrane reactor. Each step enzymatic hydrolysates were determined the antioxidative activity and their synergistic effects, compared with
and butylated hydroxytoluene (BHT). Also, we tried to investigate the antioxidative disposition of peptide which was successfully separated by gel filtration, ion-exchange chromatography, and HPIC in cultured rat hepatocytes intoxicated with tert-butyl hydroperoxide (TBHP). Second step enzymatic hydrolysate (SSEH) among all hydrolysates and
was showed the strongest antioxidative activity. The optimum concentration of antioxidative activity for SSEH was
in linoleic acid. The synergistic effects were increased in using the hydrolysate with tocopherol and BHT. In the presence of the peptide isolated from SSEH, supplemented hepatocytes exposed to TBHP showed that delayed cell killing and decreased significantly the lipid peroxidation, compared with hepatocytes not cultured with isolated peptide.

For the purpose of identification of inheritance in allotriploid between rainbow trout (Oncorhynchus mykiss) and coho salmon (O. kisutch), five isozymes, lactate dehydrogenase (LDH), malate dehydrogenase (MDH), isocitrate dehydrogenase (IDH), phosphoglucose isomerase (PGI) and phosphoglucomutase (PGM) from skeletal muscle in two species and their allotriploid were analyzed. All of these loci showed differences between two species and their allotriploid except PGI. Generally, coho salmon was more monomorphic in these isozyme loci than rainbow trout. Their allotriploids showed intermediate patterns between the parental species in those isozyme loci except PGI. As a result of this study, LDH, MDH, IDH and PSM may be used as useful genetic markers in these two species, and they also be of use in studying hybrid and allotriploid in salmonids.

Korean Journal of Fisheries and Aquatic Sciences, volume 29, issue 2, 1996, Pages 267~269
Morphology of two foreign species of tongue soles (Cynoglossidae), Cynogiossus browni and C. senekalensis, was observed based on specimens collected from Kunsan fish market from 1992 to 1994. These species are externally similar to Cynoglossus robustus from Korean coast. But these are quite distincitive from Cynogiossus robustus by interlinear scale rows, body size, other counts and proportional measurements of body. The Cynogfossus browni and C. senegalensis are only distributed in western coast of Africa and commercially imported to Korea through Pusan fish market.
