Abstract

We analyze fish pricing in the São Paulo wholesale market, the second largest seafood market in South America. Quantitative price analysis is complemented by interviews with participants in the value chain to answer how the multitude of fish products supplied in this market are related and the challenges facing future growth. The results reveal a clear separate pricing of domestically produced fishery species (whitefish and pelagics) from the internationally traded aquaculture species (tilapia and salmon). Tilapia and salmon are uniquely priced, less volatile and more persistent with a price dynamic more akin to local terrestrial meats. Fishery prices show large month-by-month fluctuations and compete more with each other. Participants in the different levels of the value chain corroborate the uniqueness of salmon and state a preference for stable availability and low prices, with less concern about the specific sourcing of fish (aquaculture/fisher, or domestic/imported).

摘要

我们分析了南美第二大海鲜市场圣保罗批发市场的鱼类定价。对价值链参与者的访谈补充了定量价格分析，以回答该市场供应的大量鱼产品之间的关系以及未来增长面临的挑战。结果显示，国内生产的渔业品种（白鲑和中上层鱼类）与国际贸易的水产养殖品种（罗非鱼和鲑鱼）有着明显的不同定价。罗非鱼和鲑鱼价格独特，波动性较小且更持久，价格动态更类似于当地陆生肉类。渔业价格逐月波动较大，竞争加剧。
