摘要翻译：
我们提出了一个单物种渔业模型，该模型将封闭季节与脉冲捕获交替进行。新奇之处在于，一个封闭季节的长度是由上次捕获的存量大小决定的。用最近引入的一种新型脉冲微分方程描述了这一过程。其主要结果是一个捕捞努力阈值，它决定了渔业的可持续性或资源的灭绝。

英文摘要：
  We present a model of single species fishery which alternates closed seasons with pulse captures. The novelty is that the length of a closed season is determined by the stock size of the last capture. The process is described by a new type of impulsive differential equations recently introduced. The main result is a fishing effort threshold which determines either the sustainability of the fishery or the extinction of the resource.
