대부분 선진국 수산업은 국가경제에 차지하는 비중은 미미하나 해양생태 보전이나 해양식량안정 등의 중요성을 고려하여 국가개발 전략적 관점에서 큰 관심을 둔다. 그리고 인구나 식량소비 규모에 비해 수산자원이 풍부한 저개발국의 수산업은 국가경제 발전의 주요한 산업적 역할을 수행한다. 최근 한국을 포함한 일부 선진국에서는 창조경제적 수산업을 통하여 새로운 성장동력을 개발하여 수산업의 산업적 역할을 보다 산업화하는 전략적 발전을 지속적으로 추진하고 있다. 수산업의 창조경제적 발전은 주로 수산자원의 합리적 보존관리, 어업인의 소득증대와 어촌사회 복지향상뿐만 아니라 새로운 수산물 시장수요 창출 등에 주안점을 두고 있다. 본 연구에서는 수산창조지수(ICSF; Index of Creativity Space for Fisheries)를 분석하여 수산업의 지속적 개발 내지 회복에 있어 창조경제적 요인의 역할과 중요성을 평가하였다. 수산업의 창조성을 결정하는 수산창조지수(ICSF)는 기술(technology), 재능(talent), 다양성(tolerance)의 결합적 결과로 구성된다. 이를 통하여 창조경제적 측면에서 수산업의 지속적 발전 가능 잠재력을 평가하게 된다. 수산창조지수(ICSF)를 이용하여 한국 수산업이 지니는 창조성을 분석한 결과 대부분 수산분야에서 창조성을 기반으로 하는 지속적 수산업 발전 전략에 높은 관심을 보였다. 특히 한국 수산업은 보다 효과적인 자원 및 어업관리 정책의 이행을 통하여 창조경제적 편익의 증대를 모색하는 전략이 높이 평가되었다.

The feeding habits of the marbled flounder Pseudopleuronectes yokohamae were studied using 384 specimens (10.7-52.3 cm in total length) collected from the West Sea, Korea between January and December 2021. P. yokohamae ate mainly polychaeta and gastropoda, incuding teleostei, caridea, euphausiacea, amphipoda and brachyura. The mean number of preys per stomach (mN/ST) showed a statistically significant difference, and the mean weight of prey per stomach (mW/ST) increased as the total length increased. P. yokohamae ate mainly teleostei in spring and winter. P. yokohamae ate mainly euphausiacea in summer and mainly polychaeta in autumn.

This paper presents the new developmental direction for fisheries policy in Korea. Korea is changing strang fisheries nation, the fact is that korea cannot effectively cope with changing fisheries situation and various fisheries difficulties, because the fisheries policy system is dispersed to each parts of the government. The results of this study is as follow: the fisheries policy in future must be able to unify of Ministry of Maritime Affairs and Fisheries, all fisheries offices must be able to relation, the regulation of fisheries policy must relieve, a coastal fishery must be able to reproduction, change of fishery structure must be able to raising fishery, consumption of fishery must be able to improvement, live of fishing village must be able to betterment, overseas fishing grounds must have to security.

The maturation and spawning of Pacific cod Gadus macrocephalus were inversigated using 2,415 samples collected monthly from January 2017 to December 2019, in the Yellow Sea of Korea. We analyzed monthly changes in gonadosomatic index (GSI), maturity stage, egg diameter (mm), the relations fecundity and total length (cm). The spawning period was February to March. Fecundity varied between 334,836 and 2,099,600 eggs. The relationship between the fecundity and TL of fish was expressed in F=186.86TL2.0954 (R2=0.7359). The percentage of sexually mature females estimated from a logistic function was over 50%, 75% and 97.5% for the size (TL) 39.3, 44.8 and 57.7 cm.

This study revealed the reproductive biology of pointhead flounder Cleisthenes pinetorum, in the middle of the West Sea of Korea. We collected samples using gill net and drag net fisheries in coastal waters from January to December 2019. Mmonthly gonodosomatic index and maturity stage results showed that the spawning period was October to December, and the females grew faster than the males. The fecundity ranged from 16,728 to 1,039,616 number of eggs, and the relationship between TL and fecundity (F) was 0.0000003TL^4.7434 (R²=0.4898). The size-frequency distribution of eggs suggested that C. pinetorum spawm once during a spawning period. The length at 50% maturity for females was estimated to be 18.9 cm.

The ichthyoplanktons were sampled by Bongo net to study the distribution of the eggs and larvae in the West coastal waters of Korea during the study period (February, May, August and October of 2017). Collected fish eggs were divided into Engraulis japonicus and unidentified species. The most dominant species, Engraulis japonicus accounted for 79.52% of the total fish egg, which was followed by unidentified species (20.48%). The total of 36 taxa in fish larvae were identified based on morphological and molecular characteristics. Fish larvae were dominant by Gobiidae species. 48.30% of the total catch in abundance, which was followed by Engraulis japonicus (31.86%). These two taxa composed 80.16% of the total collected fish larvae. The seasonal diversity index of species from the collected fish larvae in the West coastal waters in 2017 was 0.625-1.883 and the evenness index was 0.380-0.865. In addition, dominance index was 0.618-0.920 and richness was 0.573-3.189.

수산화인회석(Hydroxyapatite)는 뼈와 이빨의 무기물의 주성분으로서 칼슘과 인산염으로 구성된다. 본 실험에서는 다양한 농도의 염기조건(NaOH 0,2,4,5,10 M)하에서 서로 다른 형태의 수산화인회석을 수열합성법(hydrothermal method)을 이용해 합성하였다. 합성된 각각의 수산화인회석을 XRD로 확인하였고 일정 농도 이하에서는 octacalcium phosphate이 함께 존재한다는 것을 확인하였다. 수산화인회석 표면에 Ru를 Ion-exchange 반응을 통하여 도입하였으며, 도입된 표면을 TEM을 확인하였다. Ru를 도입한 수산화인회석을 benzyl alcohol과 benzyl amine을 산화반응에 응용하였다.
