Formerly T. Nishimura, T. Oshima and M. Otsuru studied on Anisakis-like larvae in the various marine fishes from the Japan Sea and the Pacific Ocean. In the present observation, many kinds of marine fishes from the Yellow Sea and the southern coast of Korea were. studied, with the samples from the islands: Eocheng-do, Sohuksan-do, Chuja-do and Keomun-do. The authors examined 313 samples from the adjacent waters of Korea and the distribution of the Anisakis-like larvae in the fish body was found to be 9,219 larvae of Anisakis-like larvae found in the mesentery and coelomic cavity of all samples. Of them, 8,112 Anisakis-like larvae were found from 187 samples from the southern coast of Korea, 1,107 Anisakis-like larvae were found in 126 samples from the Yellow sea (Tables 1 & 2). The fish from the southern coast of Korea are much more infected than the fish from. the Yellow Sea. The larger the fish length, the heavier infection of Anisakis-like larvae were observed.
Studies on the Propagation of a Prawn, Penaeus orientalis
KIM Kwon Doo ;
Korean Journal of Fisheries and Aquatic Sciences, volume 1, issue 1, 1968, Pages 9~18
A series of experiments since 1963 ha sbeen made on the artificial propagation of Penaeus oriental is for the purpose of improving breeding of the prawn. The results are as follows: 1. Spawning takes place in the evening, and almost completes before 10 o'clock p. m.. Number of spawns deposited by a prawn is 30,000 to 150,000. 2. Deposited spawns become nauplius stage after approximately 18 hours (about 13 hours in hatching tanks) at water temperature of
, and grow to first nauplius stage in subsequent 28 hours. 3. It takes about five days from first nauplius stage to zoea stage, and additional four or five days from first zoea stage to first mysis stage. 4. It takes approximately 2 to 3 weeks from spawning to post larva. 5. Hatching rate ranged from
, with the average of
in 1966 and
An Experiment on the Culture of Laver, Porphgra tenera, on the 'Sae-ol-bal' (triple-knotted blind) Laver Bed

Korean Journal of Fisheries and Aquatic Sciences, volume 1, issue 1, 1968, Pages 19~30
An experiment on the culture of laver, Porphyra tenera, was carried out from September 26, 1965 to February 12, 1966 at a laver farm on the coast of Gae-do, Hwacheong-myeon, Yeocheon-gun, Jeonranam-do, using 'Sae-ol-bal' (triple-knotted blind) laver bed, resulting in the following data: 1. 'Sae-ol-bal' laver, bed was less destroyed compared to ordinary (dual knotted blind) laver bed, the destruction rate being
in 'Sae-ol-bal' laver bed, while
in ordinary laver bed (Table 5). 2. The quantity of laver yield is the greatest on the edge-part, the next on the basal part, and the smallest on the middle part of the 'Sae-ol-bal' laver bed (Table 6, Figs.
). 3. The ordinary laver bed may yield better harvest on the calm farm but 'Sae-ol-bal' laver bed yields better harvest at a farm where the destruction of bed is remarkable by wind and wave action.
Analysis of the Shell Height Frequencies on the Fresh-Water Cockle, Corbicula elatior, by Means of Probability Graph
PARK Sing Won ; LEE Sung Hun ;
Korean Journal of Fisheries and Aquatic Sciences, volume 1, issue 1, 1968, Pages 31~43
1. Shell height frequencies of the fresh-water cockle, Corbicula elatior, sampled in the period of 1960 to 1963, are analyzed to assess the age composition and average growth pattern. Cumulative frequencies in a sample are traced on a probability scale, and the points of inflection on a probability graph are assumed to dissect age groups. 2. Seasonal growth of Corbicula elatior in the Naktong River ill as follows: Young cockles settle down on river-bed by June and grow rapidly during the summer season, reaching 14mm in shell height by October. From October to April the growth is very slow. The rapid growth in the second year starts around in May. 3. Survival rate per year for Corbicula elatior in the Naktong River is estimated to be
by age composition.
The Effect of Some Factors on the Mortality of Trochophora of Oyster, Crassostrea gigas
LEE Choon Koo ; LEE Jung Jae ;
Korean Journal of Fisheries and Aquatic Sciences, volume 1, issue 1, 1968, Pages 45~49
The effect of salinities, temperatures, and turbidities on the mortality of trochophora of oyster, Crassostrea gigas, was investigated at the laboratory. 1. The trochophora of oyster, transferred from normal sea water to sea water of lower or higher salinity, lost their vital activity sooner or later. The mortalities of trochophora were
at lower salinity of 15 ppt and
at higher salinity of 35 ppt respectively. 2. The high temperature above
was lethal to trochophora in normal salinity of sea water. Especially all of them died at
within 30 minutes. However, low temperatures were not lethal to trochophora than higher ones. The differences between two mortality curves at 0.5-and 1-hour treatments at each level of temperatures were not statistically significant as a result of the t-test (P>0.05). 3. It was found that the heavy turbidity (1.0 per cent) did not affect the mortality of the trochophora of oyster in a short period.

The distribution of the radioactivity of seawater along the coast and the adjacent sea of Korea has not been reported. Therefore it is neccessary to investigate this to give the basic data for reference in the field of the project applying atomic energy. A power plant of atomic energy projected by the government of R. O. K., and the Atomic Energy Agency has commenced to make general survey in geographical, meteorological and oceanographical aspects of proposed sites for it. It is a part of that survey in the field of the oceanographical investigation. The results of examination of sea water near those sites together with the fresh water of the rivers in those area are reported in this paper
Relation of Air Temperature at Mokpo Area between Early Summer and Early Autumn
HONG Sung Kun ;
Korean Journal of Fisheries and Aquatic Sciences, volume 1, issue 1, 1968, Pages 55~59
The relation of air temperature between early summer and early autumn from 1916 to 1966 was investigated. The data are brought by the statistical analysis for the purpose of the long range weather forecast. he results are summarized as follows : 1. The air temperature in early autumn at Mokpo is largely influenced by that of early summer. That is, when the air temperature in early summer is higher than the average, the temperature in early autumn has the possibility of being higher temperature in early autumn than average, the possibility being as much as
. On the contrary, when the former is lower, the latter has a possibility of becoming
below the normal year. 2. The monthly ranges of forcastable mean air temperature in early autumn will be computed by the types of total variation in early summer and the standard deviation in early autumn.
