  • When we think of fundamental problems of the aquaculture industry, there are several strict conditions, and consequently the aquaculture industry is forced to change. Fish aquaculture has a structural supply surplus in production, aggravation of fishing grounds, stagnant low price due to recent recession, and drastic change of distribution circumstances. It is requested for us to initiate discussion on such issue as “how fish aquaculture establishes its status in the coastal fishery\ulcorner, will fish aquaculture grow in the future\ulcorner, and if so “how it will be restructured\ulcorner” The above issues can be observed in the mariculture of yellow tail, sea scallop and eel. But there have not been studied concerning seabream even though the production is over 30% of the total production of fish aquaculture in resent and it occupied an important status in the fish aquaculture. The objectives of this study is to forecast the future movement of sea bream aquaculture. The first goal of the study is to contribute to managerial and economic studies on the aquaculture industry. The second goal is to identify the factors influencing the competition between production areas and to identify the mechanisms involved. This study will examine the competitive power in individual producing area, its behavior, and its compulsory factors based on case study. Producing areas will be categorized according to following parameters : distance to market and availability of transportation, natural environment, the time of formation of producing areas (leaderㆍfollower), major production items, scale of business and producing areas, degree of organization in production and sales. As a factor in shaping the production area of sea bream aquaculture, natural conditions especially the water temperature is very important. Sea bream shows more active feeding and faster growth in areas located where the water temperature does not go below 13∼14$^{\circ}C$ during the winter. Also fish aquaculture is constrained by the transporting distance. Aquacultured yellowtail is a mass-produced and a mass-distributed item. It is sold a unit of cage and transported by ship. On the other hand, sea bream is sold in small amount in markets and transported by truck; so, the transportation cost is higher than yellow tail. Aquacultured sea bream has different product characteristics due to transport distance. We need to study live fish and fresh fish markets separately. Live fish was the original product form of aquacultured sea bream. Transportation of live fish has more constraints than the transportation of fresh fish. Death rate and distance are highly correlated. In addition, loading capacity of live fish is less than fresh fish. In the case of a 10 ton truck, live fish can only be loaded up to 1.5 tons. But, fresh fish which can be placed in a box can be loaded up to 5 to 6 tons. Because of this characteristics, live fish requires closer location to consumption area than fresh fish. In the consumption markets, the size of fresh fish is mainly 0.8 to 2kg.Live fish usually goes through auction, and quality is graded. Main purchaser comes from many small-sized restaurants, so a relatively small farmer and distributer can sell it. Aquacultured sea bream has been transacted as a fresh fish in GMS ,since 1993 when the price plummeted. Economies of scale works in case of fresh fish. The characteristics of fresh fish is as follows : As a large scale demander, General Merchandise Stores are the main purchasers of sea bream and the size of the fish is around 1.3kg. It mainly goes through negotiation. Aquacultured sea bream has been established as a representative food in General Merchandise Stores. GMS require stable and mass supply, consistent size, and low price. And Distribution of fresh fish is undertook by the large scale distributers, which can satisfy requirements of GMS. The market share in Tokyo Central Wholesale Market shows Mie Pref. is dominating in live fish. And Ehime Pref. is dominating in fresh fish. Ehime Pref. showed remarkable growth in 1990s. At present, the dealings of live fish is decreasing. However, the dealings of fresh fish is increasing in Tokyo Central Wholesale Market. The price of live fish is decreasing more than one of fresh fish. Even though Ehime Pref. has an ideal natural environment for sea bream aquaculture, its entry into sea bream aquaculture was late, because it was located at a further distance to consumers than the competing producing areas. However, Ehime Pref. became the number one producing areas through the sales of fresh fish in the 1990s. The production volume is almost 3 times the production volume of Mie Pref. which is the number two production area. More conversion from yellow tail aquaculture to sea bream aquaculture is taking place in Ehime Pref., because Kagosima Pref. has a better natural environment for yellow tail aquaculture. Transportation is worse than Mie Pref., but this region as a far-flung producing area makes up by increasing the business scale. Ehime Pref. increases the market share for fresh fish by creating demand from GMS. Ehime Pref. has developed market strategies such as a quick return at a small profit, a stable and mass supply and standardization in size. Ehime Pref. increases the market power by the capital of a large scale commission agent. Secondly Mie Pref. is close to markets and composed of small scale farmers. Mie Pref. switched to sea bream aquaculture early, because of the price decrease in aquacultured yellou tail and natural environmental problems. Mie Pref. had not changed until 1993 when the price of the sea bream plummeted. Because it had better natural environment and transportation. Mie Pref. has a suitable water temperature range required for sea bream aquaculture. However, the price of live sea bream continued to decline due to excessive production and economic recession. As a consequence, small scale farmers are faced with a market price below the average production cost in 1993. In such kind of situation, the small-sized and inefficient manager in Mie Pref. was obliged to withdraw from sea bream aquaculture. Kumamoto Pref. is located further from market sites and has an unsuitable nature environmental condition required for sea bream aquaculture. Although Kumamoto Pref. is trying to convert to the puffer fish aquaculture which requires different rearing techniques, aquaculture technique for puffer fish is not established yet.

  • 낙산사는 익조(翼祖)인 이행리(李行里)가 관음굴에서 후사점지를 기원하여 도조(度祖)를 낳게 해준 사찰이었다. "태조실록" 등에 도조는 조선개창의 예언을 직접적으로 받은 인물로 기록된다. 낙산사는 창건 이래 관음신앙의 본산으로 그 명성이 꾸준히 이어져 왔으며, 도조의 잉태로 조선의 창업과 관련있는 사찰로 주목받았다. 도조의 낙산사 관음굴 기복잉태설은 조선후기까지 왕실과 사대부들 사이에서 회자되었다. 이성계(李成桂)도 낙산사에 관심을 보였고, 세조(世祖)가 강원도 순행(巡幸) 시 예종의 원찰로 중창하였다. 낙산사는 세조가 왕권강화 등을 위해 불교적 상서(祥瑞)와 이에 따른 사찰의 중창 등을 집중적으로 시행하던 시기에 중창되었다. 이러한 정책과 달리 낙산사 중창은 세조가 자식 예종의 무병장수 기원을 위한 신앙심의 발현으로 추진한 것이었다. 세조의 낙산사 중창의지는 매우 강했다. 그러므로 낙산사는 국가의 전폭적 후원을 받으며 중창되었다. 낙산사 중창비용은 국가에서 모두 충당하는 것으로 표면화하고 추진하였으나, 워낙 큰 공역이었으므로 중창에 필요한 물자와 비용조달에 따른 지역의 피해는 매우 컸다. 조선왕실에서는 낙산사 중창으로 물의를 일으켰던 감동승(監董僧) 학열(學悅) 또한 비호해 주었다. 낙산사는 중창직후 왕실의 지원으로 사세가 더욱 번창하였다. 예종과 성종은 전지(田地)와 노비 등을 낙산사에 하사하고, 강원도에서 공납하던 소금을 사급(賜給)하는 등 후원을 아끼지 않았다. 뿐만 아니라 낙산사 경내를 보호하기 위해 낙산사 인근 양양대로를 폐지하고, 새 길을 개설하였다. 그리고 낙산사 해안 십리의 구역에 포어(捕漁)를 금지하는 금표를 세워 민간의 출입을 금지시켰다. 낙산사는 조선후기에 들어 크게 쇠락했으나 왕실의 원당보호정책 속에서 후원이 지속되었고, 원당으로서의 명맥과 사세를 유지해 나갔다.
