Biological reference points (BRPs) derived from per-recruit analyses are commonly used in inferring stock status and serve as the target or threshold fisheries management. However, estimation of BRPs may be impacted by variability life history processes, particularly, individual growth rates often display substantial seasonal oscillations but seldomly considered analyses. Using four commercial ...

The food consumption to biomass ratio (C) is one of the most important population parameters in ecosystem modelling because its quantifies the interactions between predator and prey. Existing models for estimating C in fish populations are per-recruit cohort models or empirical models, valid only for stationary populations. Moreover, empirical models lack theoretical support. Here we develop a ...

This report presents a framework for per-pixel analysis of the qualitative and quantitative aspects of luminous environments. Recognizing the need for better lighting analysis capabilities and appreciating the new measurement abilities developed within the LBNL Lighting Measurement and Simulation Toolbox, “Per-pixel Lighting Data Analysis” project demonstrates several techniques for analyzing l...

Stocks' yield and size per recruit are widely used to provide fisheries management guidance. This study provides details for analyzing the composite (i.e. age-aggregated or stage-structured) (CYPR) model CYPR14, proposes CYPR14 as a tool tropical fisheries. The fishing mortality rates maximizing CYPR ( F ) associated with marginal increase in 0.1 target spawning potential ratio (CSPR; 35%CSPR 4...
