A size and trait-based marine community model was used to investigate interactions, with potential implications for yields, when a fishery targeting forage fish species (whose main adult diet is zooplankton) co-occurs with a fishery targeting larger-sized predator species. Predicted effects on the size structure of the fish community, growth and recruitment of fishes, and yield from the fisheries were used to identify management trade-offs among the different fisheries. Results showed that moderate fishing on forage fishes imposed only small effects on predator fisheries, whereas predator fisheries could enhance yield from forage fisheries under some circumstances.
采用一种基于大小和特征的海洋群落模型来研究相互作用，这些相互作用可能对渔业产量产生影响，此时一个针对饲料鱼类物种（其主要成年食物是浮游动物）的渔业与一个针对较大型捕食者物种的渔业同时存在。预测对鱼类群落的大小结构、鱼类生长和补充以及渔业产量的影响，以确定不同渔业之间的管理权衡。结果表明，对饲料鱼类的适度捕捞仅对捕食者渔业造成很小的影响，而在某些情况下，捕食者渔业可以提高饲料鱼类渔业的产量。
