Primary production must constrain the amount of fish and invertebrates available to expanding fisheries; however the degree of limitation has only been demonstrated at regional scales to date. Here we show that phytoplanktonic primary production, estimated from an ocean-colour satellite (SeaWiFS), is related to global fisheries catches at the scale of Large Marine Ecosystems, while accounting for temperature and ecological factors such as ecosystem size and type, species richness, animal body size, and the degree and nature of fisheries exploitation. Indeed we show that global fisheries catches since 1950 have been increasingly constrained by the amount of primary production. The primary production appropriated by current global fisheries is 17-112% higher than that appropriated by sustainable fisheries. Global primary production appears to be declining, in some part due to climate variability and change, with consequences for the near future fisheries catches.
初级生产力必须限制鱼类和无脊椎动物的数量，以满足不断扩张的渔业需求；然而，到目前为止，这种限制程度仅在区域尺度上得到了证明。在这里，我们表明，通过海洋颜色卫星（SeaWiFS）估算的浮游植物初级生产力与大海洋生态系统的全球渔业捕捞量有关，同时考虑了温度以及生态因素，如生态系统规模和类型、物种丰富度、动物体型，以及渔业开发的程度和性质。事实上，我们表明，自 1950 年以来，全球渔业捕捞量越来越受到初级生产力的限制。目前全球渔业所利用的初级生产力比可持续渔业所利用的高出 17-112%。全球初级生产力似乎正在下降，部分原因是气候的多变性和变化，这对未来的渔业捕捞量产生了影响。
