In this paper, we studied the consciousness of Fisheries high school students Through these kinds of works, this paper will focus on how to activate the Fisheries high school in Kyungbuk province. Primarily, research of the consciousness of people living in the fisheries community of the Kyungbuk coast has been engaged in fisheries. Secondly, research is done the consciousness of Fisheries high school students. Thirdly, research of consciousness of neighboring middle school teachers. Finally, searching for reform measures toward activating Fisheries high schools in the whole country. The conclusions of the study were as follows: First, the proper view of fisheries should be settled again. The understandings of basic knowledge about maritime affairs and fisheries in the stages of elementary schools and middle schools are needed. Secondly, in order to find a way out of the difficulties in fishering villages, governmental financial support has to be presente. from the view of fisher folks who are engaged in the fisheries. Thirdly, larger portions of economic value should be allocated to fisheries villages by improving fisheries structure of the fishery. Actually, lower incomes have burdened fisheries villagers with more debts. Fourthly, academic and care counseling must concentrate on the diversification of courses after graduation from fisheries high schools. Realistically, students of fisheries high schools are longing to enter into universities. Fifthly, reorganization of specialized highschool systems, changes of titles of schools and reconstruction of departments should be steadily carried out. Finally, high morale of fisheries highschool teachers should be revised using various steps. They didn't appear to be proud of their teaching jobs. Supervisors ought to exchange their opinions with teachers for the purpose of development of fisheries high schools.

The sea of north-east Asia is biologically interrelated and one country's mishap in the management of fisheries could have a critical effect upon the other. Accordingly under the TAC system adopted by all the countries of Korea, Japan and China, the mismanagement o( trans-boundary fish stocks under the provisional fisheries agreement prior to the delimitation of EEZ could lead to the irrevocable depletion of fisheries resources in case of absence of close cooperation among the countries concerned. To tackle the problems above, it is necessary, from a short term perspective, to promote the combined efforts to do researches on fisheries resources, find ways to improve the transparency of fisheries management, adjust the fisheries management regulations of each country, standardize fishing gears and methods, and exchange fisheries-related statistics and data for socio-economic analysis and strengthen joint research activities for the mutual benefits. From a longer term prospective, regional fisheries organization need to be set up to oversee the whole area of north-east Asian sea. The organization as such could play a role in adjusting the conflicting interests of Korea, Japan and China, and efficiently manage the fisheries resources, which is complex and challenging in nature. In addition, unlike China, the historical fisheries relationship between Korea and Japan, spirit of reciprocity and the Article 62 of the United Nations Convention On the Law Of Sea need to be taken into account when seeking for fisheries cooperation between the two countries through the international specialization. In other words, the data obtained through the joint researches on the fisheries resources for the specific ocean along with such factors as capital, labor, fisheries technology and consumption of fish products could be used to assign the specific sector of fisheries to the country who has a comparative advantage, thus achieving the mutually benefiting results Up to the present, concerted efforts by Korea, Japan and China on the fisheries cooperation have been consistently made, but the results have yet to be materialized, It is also beyond doubt that governmental consultations among the countries should be made on a consistent basis, but non-governmental organizations' exchanges and related joint researches will more likely help bring about the desired fruition in a shorter time.

The feeding habits of Lycodes tanakae Eelpout were studied with 722 specimens collected from March 2011 to December 2012 in the coastal waters of the middle East Sea. The main prey of L. tanakae were fish, molluscs and arthropods. Nevertheless annelida, echinodermata and others were found in small amounts in the stomach contents. The L. tanakae stomach was empty of contents in 50.9% of specimens. While smaller size specimens of L. tanakae (less than 40 cm) fed mainly on euphausiids and amphipods, the larger specimens (more than 40 cm) fed on the fish Allolepis hollandi and Icelus cataphractus, and the molluscs Berryteuthis magister and Watasenia scintillans. The main prey items of L. tanakae varied seasonally. The fish Lycodes nakamurai was the dominat prey from November to January during its spawning season. Euphausiids and amphipods of the arthropods were the dominant prey from February to April. The molluscs Berryteuthis magister and Watasenia scintillans were the dominant prey from May to September. The diversity index (H') of diets showed variations by length class and month; the highest values were 2.61 in the length class of 51-55 cm, and the monthly highest were 2.68 in September with 23 species and 2.65 in November with 18 species. The highest dominance index (D') of diets was 0.57 in the length class of 31-35 cm, and the monthly highest was 0.71 in February. Cluster analysis divided prey groups into four groups by length class and three groups by monthly prey items. The gonad index gradually increased during the process of maturation while, contrary, stomach content index decreased during this period.

The age and growth of pointhead flounder, Hippoglossoides pinetorum caught by gill nets was analyzed in this study from March 2015 to July 2017. New annuli were formed in H. pinetorum otoliths annually, and the boundary was set between the opaque and translucent zones from March and April. The relationships between total length (TL) and body weight (BW) were $BW=0.0025TL^{3.409}$ ($r^2=0.9551$) for females and $BW=0.0057TL^{3.138}$ ($r^2=0.9163$) for males. In this study, the ring of pointhead flounder, H. pinetorum was formed between 3 and 8 for females and between 3 and 6 for males. Total length (TL) and otolith radius (OR) were measured as follows: TL = 7.142 OR + 0.769 ($r^2=0.793$) for females and TL = 6.498 OR + 1.706 ($r^2=0.652$) for males. The mean distances of first ring ($r_1$) were 0.92 mm and 0.91 mm for females and males respectively. The TLs at the time of annulus formation, back-calculated from the otolith-length relationship by reference to the von Bertalanffy growth curves, were $L_t=43.59(1-e^{-0.15(t+0.007)})$ for females and $L_t=28.13(1-e^{-0.26(t+0.006)})$ for males while the growth between female and male was different.

The interest in greenhouse gases (GHG) emitted from all industries is emerging as a very important issue worldwide. This is affecting not only the global warming, but also the environmentally friendly competitiveness of the industry. The fisheries sector is increasingly interested in greenhouse gas emissions also due to the Paris Climate Agreement in 2015. Korean industry and government are also making a number of effort to reduce greenhouse gas emissions so far, but the effort to reduce GHG in the fishery sector is insufficient compared to other fields. Especially, the investigation on the GHG emissions from Korean fisheries did not carry out extensively. The studies on GHG emissions from Korean fishery are most likely dealt with the GHG emissions by fishery classification so far. However, the forthcoming research related to GHG emissions from fisheries is needed to evaluate the GHG emission level by species to prepare the adoption of Environmental labels and declarations (ISO 14020). The purpose of this research is to investigate which degree of GHG emitted to produce the species (swimming crab and snow crab) from various fisheries. Here, we calculated the GHG emission to produce the species from the fisheries using the life cycle assessment (LCA) method. The system boundary and input parameters for each process level are defined for LCA analysis. The fuel use coefficients of the fisheries for the species are also calculated according to the fuel type. The GHG emissions from sea activities by the fisheries will be dealt with. Furthermore, the GHG emissions for producing the unit weight species and annual production are calculated by fishery classification. The results will be helpful to establish the carbon footprint of seafood in Korea.

Balssaxius habereri (Balss, 1903) has been newly reported in Korean waters. This species was previously known from the Pacific coast of northern Japan, Korea Strait, Yellow Sea, and Japanese coast of the East Sea. Specimens were collected from western Jeju Island using otter trawls at depths of 65-85 m. Regarding Korean axiid shrimps, a single species, Boasaxius princeps (Boas, 1880), previously known as Axiopsis princeps in Korea, has been recorded. B. habereri is easily distinguished from B. princeps as it does not have tufts of setae on its body and males do not have the first pleopod. Morphological descriptions and color photos of the specimens are provided.

Korea has experienced a Cochlodinium polykrikoides red tide 10 out of the last 10 years (1993-2002). This species of red tide has been experienced at least once by all the southern coast of the Korean peninsular and has been transported up the southeastern coast all the way to the northeastern coast since 1995. The impression is that red tide is spending and becoming more common not only in the nearest coastal water, but also in the offshore. (omitted)
