The world fisheries are mainly focused on the yield from fishing, and hence maximum sustainable yield (MSY) policy has become the most popular management tool. But this aim of maximum productivity, particularly in the multitrophic system, impacts the resilience, considering the potential of the system to absorb the disturbances applied to the system. Due to harvesting effort used on different individual trophic levels, the trade-offs and synergies between yield and resilience of a tri-trophic food chain system have been studied. In Holling type II functional response, the enrichment of carrying capacity can destabilize the system and may adversely affect the system resilience. In the case of prey harvesting, for both Holling type I and II responses, the existence of MSY depends on some parametric restrictions, but resilience maximizing yield (RMY) always exists. For predator harvesting, only RMY may be a favorable harvesting strategy as MSY does not exist. But for the top predator harvesting with both for Holling type I and II functional responses, both the pair MSY and RMY exist. Either MSY, or RMY, or a balanced approach between them, maybe implemented depending upon the requirements of more yield, or more resilience, or balancing them.

世界渔业主要集中于捕捞的产量，因此，最大可持续产量（MSY）政策已成为最受欢迎的管理工具。但是，考虑到系统吸收施加到系统的干扰的潜力，特别是在多营养系统中，实现最高生产率的目标会影响弹性。由于在不同的营养级别上使用了收割方法，因此研究了三营养食物链系统的产量和韧性之间的权衡和协同作用。在Holling II型功能性反应中，承载能力的增强会破坏系统的稳定性，并可能对系统的弹性产生不利影响。就猎物而言，对于Holling I型和II型响应，MSY的存在取决于某些参数限制，但是始终存在使产量最大化（RMY）的弹性。对于捕食者，由于不存在MSY，因此只有RMY可能是一种有利的捕捞策略。但是对于同时具有Holling I型和II型功能性反应的顶级捕食者，MSY和RMY对都存在。MSY或RMY或它们之间的一种平衡方法，可以根据更高产量，更高弹性或平衡它们的要求来实施。
