2011年2月，世界粮食价格达到历史最高水平，目前仍几乎是2000年的两倍半。尽管全世界有30亿人将海产品作为动物蛋白的主要来源，但联合国粮食及农业组织（FAO）并没有跟踪海产品的价格。我们通过制定一个全球海产品价格指数来填补这一空白，该指数有助于了解粮食危机，并可能有助于避免危机。鱼类价格指数依赖于贸易统计数据，因为海产品的国际贸易量很大，使非贸易海产品面临来自进出口的价格竞争。因此，容易更新的贸易数据可以代表国内海产品价格，而国内海产品价格在许多区域难以观察，而且更新全球数据的成本很高。对不同国家价格竞争程度的计算支持依赖贸易数据的合理性。总的来说，FPI比其他食品价格指数，包括油，谷物和乳制品，波动性更小，价格飙升更少。FPI通常反映海产品的稀缺性，但也可以按生产技术、鱼种或地区分为指数。将外国证券投资分为捕捞渔业和水产养殖表明，近年来捕捞渔业资源日益稀缺，但水产养殖的增长与需求保持同步。从地区来看，海鲜价格波动性各不相同，部分价格呈负相关。这些模式表明，尽管海产品的可交易性很高，但区域供应冲击对海产品价格影响很大。
World food prices hit an all-time high in February 2011 and are still almost two and a half times those of 2000. Although three billion people worldwide use seafood as a key source of animal protein, the Food and Agriculture Organization (FAO) of the United Nations–which compiles prices for other major food categories–has not tracked seafood prices. We fill this gap by developing an index of global seafood prices that can help to understand food crises and may assist in averting them. The fish price index (FPI) relies on trade statistics because seafood is heavily traded internationally, exposing non-traded seafood to price competition from imports and exports. Easily updated trade data can thus proxy for domestic seafood prices that are difficult to observe in many regions and costly to update with global coverage. Calculations of the extent of price competition in different countries support the plausibility of reliance on trade data. Overall, the FPI shows less volatility and fewer price spikes than other food price indices including oils, cereals, and dairy. The FPI generally reflects seafood scarcity, but it can also be separated into indices by production technology, fish species, or region. Splitting FPI into capture fisheries and aquaculture suggests increased scarcity of capture fishery resources in recent years, but also growth in aquaculture that is keeping pace with demand. Regionally, seafood price volatility varies, and some prices are negatively correlated. These patterns hint that regional supply shocks are consequential for seafood prices in spite of the high degree of seafood tradability.
