    <p>In recent years, Japanese common squid that the main type of squid produced in Japan has been suffering from poor catches.　The poor catch of Japanese common squid is an issue that affects the entire value chain from production to consumption.</p><p>The market for processed squid products is diverse.　This study focuses on the sales trend of processed squid products in retail and aims to clarify the aspects of the changes in the contemporary situation.</p><p>The research methodology focused on the analysis of point of sales （POS） data.　The POS data used in this study were collected from the top seven supermarkets in Japan in terms of sales, from which an expanded estimation was made to estimate the sales value of the Japanese retail industry.　The period of analysis was from 2013 to 2019, when data were obtained.　The years 2020 to 2022, when the Covid-19 spread, were excluded from the scope of the study because of temporary changes in consumption behavior due to refraining from going out.</p><p>The results of the study showed that the impact of the decrease in squid production was small for higher processed products （delicacies and confectionery （dry））, but very large for lower processed products （squid rounds and slices, sashimi, boiled squid）, resulting in a large decrease in the sales value of these products.</p>

    Language：Japanese   Publisher：Japanese Journal of Fisheries Economics  

    <p>In recent years, the number of buyers involved in the formation of fair price for marine products through auctions etc. at local wholesale markets has been decreasing.　Under this circumstance, how is the price formation function of local wholesale market being maintained?　This study conducts a survey of wholesale markets in production areas where the number of buyers is decreasing and aims to clarify the actual situation of primary price formation for marine products, especially the measures taken by FCA to maintain their function, as well as their effectiveness and limitations.　The results of the survey on the Eguchi FCA in Kagoshima Prefecture showed that the price formation method has changed from auctions to negotiated transaction.　It was also confirmed that the share of purchases by a buyer has increased, and it makes difficult to maintain a fair price formation.　Under these situations, FCA’s direct sales facility makes inroads as buyer and maintains a competitive environment in price formation.　In addition, the facility retails, and wholesales local marine products to customers.　However, the total volume of marine products that can be handled in the local wholesale markets has shrunk, the FCA has been forced to respond by production adjustment.</p><p>This study has revealed that it has become extremely difficult to maintain the fair price formation function in local wholesale market where the number of buyers has been decreasing.　In addition, the importance of replacing the various buyer’s distribution functions by FCA to maintain the price formation function was also clarified.</p>
