Abstract

Per-recruit models have been widely used since the onset of modern fisheries science, particularly in data-limited situations. When the study fishery is a pulse fishery, namely a fishery operating over a brief period followed by a long fallow period, exploitation rates rather than fishing mortality rates are employed to calculate per-recruit quantities. The literature suggests that a discrete per-recruit model is more appropriate than a continuous per-recruit model when per-recruit quantities are expressed as a function of exploitation rates. For this reason, Erisman et al. [Erisman, B. E., Grüss, A., Mascarenas-Osorio, I., Lícon-González, H., Johnson, A. F., and López-Sagástegui, C. 2020. Balancing conservation and utilization in spawning aggregation fisheries: a trade-off analysis of an overexploited marine fish. ICES Journal of Marine Science, 77: 148–161.] recently developed a discrete per-recruit model to examine the impacts of altering exploitation rates for the Gulf corvina (Cynoscion othonopterus) pulse fishery. Using Erisman et al.’s (Erisman, B. E., Grüss, A., Mascarenas-Osorio, I., Lícon-González, H., Johnson, A. F., and López-Sagástegui, C. 2020. Balancing conservation and utilization in spawning aggregation fisheries: a trade-off analysis of an overexploited marine fish. ICES Journal of Marine Science, 77: 148–161.) data, we demonstrate in detail that, under certain conditions, it is reasonable to employ a continuous per-recruit model for a pulse fishery system. We then use the designed continuous per-recruit model to demonstrate how the timing of the pulse fishery within the year relative to the timing of reproduction can be accounted for in a per-recruit model, and we explore the impacts of these model developments. This article serves as a strong basis for future studies that model pulse fishery systems in data-limited situations.

在数据有限的情况下对脉冲渔业系统进行建模

摘要

自现代渔业科学开始以来，按招聘人数模型已被广泛使用，特别是在数据有限的情况下。当研究渔业为脉冲渔业时，即在短暂的时期内经营一段较长的休耕期的渔业之后，将采用开垦率而不是捕捞死亡率来计算按兵种数量。文献表明，当按招募数量表示剥削率时，离散的按招募模型比连续的按招募模型更合适。为此，Erisman等人。[Erisman，BE，Grüss，A.，Mascarenas-Osorio，I.，Lícon-González，H.，Johnson，AF和López-Sagástegui，C.2020。平衡养护和利用产卵聚集渔业：权衡取舍对过度开发的海鱼的分析。ICES海洋科学杂志，捕食夜蛾）脉冲渔业。使用Erisman等人的方法（比利时Erisman，Grüss，A。Mascarenas-Osorio，L​​.con-González，H。Johnson，AF和López-Sagástegui，C。2020。平衡产卵的保护和利用）集合渔业：对过度开发的海洋鱼类的权衡分析（ICES海洋科学杂志，77：148–161。）数据，我们详细证明，在某些条件下，采用连续的按兵种模型是合理的用于脉冲渔业。然后，我们使用设计的连续逐招聘模型来说明如何在逐招聘模型中考虑一年中相对于繁殖时间的豆类捕捞时间，并探讨这些模型发展的影响。本文为将来在数据有限的情况下对豆类渔业系统建模的研究提供了坚实的基础。
