全球鱼类供应链每年处理约 1.79 亿吨产品(截至 2018 年)。运输和分销是鱼类供应链的重要组成部分,因为鱼类和贝类是全球贸易量最大的食品商品之一,2017 年的贸易额约为 1530 亿美元。在这里,我们表明,忽略鱼类运输(无论是陆路运输还是航空运输)对环境的影响,忽略了鱼类供应总量环境影响中值得注意的一部分。我们发现,考虑到(1)所有威斯康星州县作为生产点,(2)芝加哥、密尔沃基和明尼阿波利斯市作为消费点,以及(3)有效、半有效和无效的空间供暖方法,考虑到从离岸生产点的航班运输,本地鱼类供应对环境的影响显着低于进口鱼类供应。这意味着尽管寒冷天气水产养殖的供暖需求可能会增加,但提高当地鱼类生产能力以增强鱼类供应的环境可持续性至关重要。
The global fish supply chain handles∼ 179 million tons of product annually (as in 2018). Transportation and distribution are an important part of fish supply chain, as fish and shellfish are one of the largest globally traded food commodities with a trading value of∼ $153 billion in 2017. Here we show that disregarding the environmental impacts of fish transportation, either land transit or flight, neglects a noteworthy portion of total fish provisioning environmental impacts. We identified that local fish provision, considering (1) all Wisconsin counties as production points,(2) cities of Chicago, Milwaukee, and Minneapolis as consumption points, and (3) effective, semi-effective, and ineffective space heating approaches, has significantly lower environmental impacts than imported fish provision, considering flight transportation from offshore production points. Meaning the necessity to elevate local fish production capacity to enhance the environmental sustainability of fish provision is essential, despite potential elevated heating demands for cold-weather aquaculture.
