Abstract

Seasonality is a natural feature of wild caught fisheries that introduces variation in food supply, and which often is amplified by fisheries management systems. Seasonal timing of landings patterns and linkages to consumption patterns can have a potentially strong impact on income for coastal communities as well as import patterns. This study characterizes the relationship between seasonality in seafood production and consumption in the United States by analyzing monthly domestic fisheries landings and imports and retail sales of farmed and wild seafood from 2017 to 2019. Analyses were conducted for total seafood sales, by product form, by species group, and by region of the United States. The data reveal strong seasonal increases in consumption around December and March. Seasonal increases in consumption in Spring and Summer occurred in parallel with domestic fishing production. Domestic landings vary by region, but most regions have peak fishing seasons between May and October. Alaska has the largest commercial fishery in the United States and seasonal peaks in Alaska (July/August, February/March) strongly influence seasonality in national landings. Misalignment between domestic production and consumption in some seasons and species groups creates opportunities for imports to supplement demand and lost opportunities for domestic producers.

摘要

季节性是野生捕捞渔业的一个自然特征，它会导致食物供应发生变化，而且通常会被渔业管理系统放大。上岸模式的季节性时间以及与消费模式的联系可能对沿海社区的收入以及进口模式产生强烈影响。本研究通过分析 2017 年至 2019 年每月国内渔业上岸量以及养殖和野生海鲜的进口和零售额，描述了美国海鲜生产和消费的季节性关系。分析了海鲜总销售额，按产品形式，物种组，并按美国地区划分。数据显示，消费在 12 月和 3 月前后出现强劲的季节性增长。春季和夏季消费的季节性增长与国内渔业生产同时发生。国内上岸量因地区而异，但大多数地区在 5 月至 10 月之间是捕鱼高峰期。阿拉斯加拥有美国最大的商业渔业，阿拉斯加的季节性高峰（7 月/8 月、2 月/3 月）强烈影响全国上岸量的季节性。某些季节和物种组的国内生产和消费之间的错位为进口补充需求创造了机会，而国内生产者则失去了机会。二月/三月）强烈影响国家登陆的季节性。某些季节和物种组的国内生产和消费之间的错位为进口补充需求创造了机会，而国内生产者则失去了机会。二月/三月）强烈影响国家登陆的季节性。某些季节和物种组的国内生产和消费之间的错位为进口补充需求创造了机会，而国内生产者则失去了机会。
