The distribution and biomass of pelagicfish in centeral coast of west sea of Korea were studied by the scientific echo sounder from September 2006 to June 2007, every four season. The survey was performed by using 200kHz dual beam system, transmitter-receiver and indicator afterward recorded data was handled by using echo view software. The biomass was estimated using identification of object fish, acoustics data of volume backscattering coefficient(Sv), area backscattering coefficient(Sa), target strength(TS), and length and weight of target fish by sampling. Based on the survey line, divided the survey waters with 6 sections was 227.68km2. The area backscattering strength(SA) of each season indicated -62.0~-68.0dB in September(autumn), -63.0~-72.0dB in November(winter), -65.0~-71.0dB in March(spring) and -55.0~-66.0dB in June(summer). In addition, the mean target strength(TS) of many fishes distributed in the survey area in September, November, March and June was -57.0dB, -69.2dB, -69.1dB and -64.8dB, respectively. The catch rate by offshore stow net was occupied 98~99% of anchovy in september, 36~44% of akiami paste shrimp in november, 35~59% of akiami paste shrimp in march and 53~64% of southern rough shrimp, 13~14% of beka squid in june.

The purpose of this paper is to find some factors that affect the Fisheries Wholesale Market(hereafter FWM), there are two different FWMs in the fisheries marketing channel. The one is in the landing port and the other is in the inland big city. The FWM in the landing port has annually decreased the ratio of sale from 80.9% of national catches in 1980 to 64.5% in 1996. The other FWM in the big city has also decreased the amount of sale with 82.5% in 1996 comparing with in 1992 being similar to the ratio of sale. I want to find what factors affect the ratio and the amount of sale in FWM. I understand finally, among of environment variables around FWM, 3 factors of domestic and 2 factors of foreign environment affect FWM powerfully as follow. Domestic factors 1. The Voluntary Sale of Catches : Fishermen couldn’t sell their catches at the place where they wanted to sell until the law was amended. Before September 1, 1997, they should land and sell their catches in force at the fishermen’ co-op that has a kind of wholesale market. Now they can do with it as they please. 2. The Rapid Growth of Large Store and Restaurant : Owing to high growth of Korean economy, many people become to enjoy more sea-food. And then, the sea-food stores and restaurants would be larger and higher. They need to get fishes cheaper, in time, resonable quantity in order to furnish fishes into consumer. They understand they can buy fishes cheaper from producer than from wholesaler by saving distribution expenses and fresher by lessening number of distribution channel. 3. The Development of Information, Storage and Transportation Industry : the producer and the consumer can obtain the information of opposite area each other by Lan., Internet., Fax., Tel., etc. instead of wholesale market. The transaction between producer and consumer could be stimulated by better physical distribution functions and facilitating functions. Foreign factors 1. Opening Domestic Fisheries Market Fully In 90’s, the amount of fisheries import has increased average 21.6% against 1.5% of fisheries export growth every year. We forecast the amount of import would be more and more after import was opened fully September 1, 1997. But importer don’t like to sell their import goods at wholesale market by auction. 2. Foreign Stores Entering into Domestic Market : Foreigners can establish their fisheries stores in Korean market as commission agent, wholesaler, retailer and franchiser except fisheries wholesale auction market. They will get more and more market share ratio that Korean fisheries whole sale market has kept and they also want to sell a lot of fisheries import goods even though FWM would be worse. Many environment factors around FWM go from bad to worse interacting FWM. I dare to say Korean wholesale market should make a special plan as soon as possible to overcome the worse environment.

Why are auctlons so prevalent in fisheries iields? One answer is, perhaps, that ?!sheries products have no standard value. The price ()f any catch of fish (at least of fish destined for the fresh fish market) depends on the demand and supply conditions a1. a s:~ecihc moment of time, mfluenced by prospective market developments and prices must be remade for each transactlOn. There are various auction schemes including wntten-bld rnethod in Korea like other countries . It IS dlfficult to make decision the app!tcation of auctlon sellin앙 in market distribution. One reason is the absence of adequate data on which to base flrrn statements. There is very little precise mformatlon about the relative volume handled by auction scheme as cornpared with other sales schernes. Because of the pauClty rehable data, one rnust depend largely on Cjua!itative in attempting to above thlS problern. This paper is designed to examme WhlCh auction scheme is more efficlent as a econornlC tool by introducing the three auctions, as sarnples, utllized in Koheung penmsula. Koheung coast wlth abundant fisheries resource, locates on the Mlddle-South part m Korea and has three auction firrn operating by fisheries coop. for sellmg of dry fish included sea weed, \ive fish and fresh fish respectively. As a result, 1 found that there 긴re three interesting auction ~;c''lemes as follow 1. More than one winners are sεlected as buyers.
