A pulse fishery is one where fishing occurs during a short period each year and is zero for the rest of the year. Grüss et al. proposed a continuous per-recruit model for such fisheries. However, this analysis is based on per-recruit equations that were derived under the assumption that fishing mortality is constant in time and, thus, do not apply to fisheries where F varies, such as a pulse fishery. A correct continuous per-recruit formulation for pulse fisheries is derived. In most cases, the continuous per-recruit model can be closely approximated by a discrete model, where the integrals are replaced by sums. A modification in the Baranov catch equation for pulse fisheries is also derived that can used to compute annual exploitation rates.

脉冲渔业的每个新兵建模：评论“在数据有限的情况下为脉冲渔业系统建模”

脉冲渔业是一种每年在短时间内进行捕捞并且在一年中剩余时间为零的渔业。格鲁斯等人。为此类渔业提出了一个连续的每次招募模型。然而，该分析基于每个新兵方程，该方程是在假设捕捞死亡率随时间保持不变的情况下得出的，因此不适用于 F 变化的渔业，例如脉冲渔业。导出了脉冲渔业的正确连续每新兵公式。在大多数情况下，连续的 per-recruit 模型可以用离散模型来近似，其中积分被总和代替。还推导出了对脉冲渔业 Baranov 捕捞量方程的修改，可用于计算年开采率。
