Discover how fishing pressure reshapes fish populations and biomass growth using a precise numerical model.
This scholarly work examines how removing older fish through fishing alters the age structure, growth rates, and spawning stress mortality of exploited populations. It explains the assumptions behind applying a numerical model to real-world data and highlights how different species respond to fishing pressure. The book also shows how long-term age composition informs estimates of senescent mortality and its role in population dynamics.
With clear figures and practical examples, the text demonstrates how biomass growth rates depend on the age distribution and on recruitment scenarios. It also discusses the need for species-specific data when modeling fishing effects and the potential uses of these methods in ecosystem or single-species assessments.
- How fishing alters age structure and exploitable biomass in fish populations
- How growth rate of biomass responds to different fishing mortalities and recruitment assumptions
- Relationships between fishing mortality, spawning stress mortality, and biomass terms
- Guidance on applying the BIODIS and FISHMO tools for population analysis
Ideal for readers of fisheries science, population dynamics, and resource management seeking a concrete, model‑based view of fishing’s long‑term effects.
