TLDR
In this paper, the authors present a case study where risk analysis can enhance the value of scientific advice to fishery managers by expressing the uncertainty inherent in stock assessments in terms of biological risk.Abstract:

Incorporating habitat preference into the stock assessment and management of blue marlin (Makaira nigricans) in the Pacific Ocean
TL;DR: Assessments indicate that Pacific blue marlin population is in an over-exploited state, with current spawning stock biomass below the level corresponding to maximum sustainable yield (SMSY) and current fishing mortality exceeding that needed to achieve MSY (FMSY).

Implementing a model for data-poor fisheries based on steepness of the stock-recruitment relationship, natural mortality and local perception of population depletion. The case of the kelp Lessonia berteroana on coasts of north-central Chile
TL;DR: In this paper, a population depletion model is reparametrized to simplify biological reference point estimates related to a maximum sustainable yield for brown kelp harvested off north-central Chile (25°17′S−29°30′S).

Meeting yield and conservation objectives by balancing harvesting of juveniles and adults
TL;DR: It is shown that PGY harvesting strategies can give large conservation benefits and equal harvesting rates of juveniles and adults is often a good strategy, and measures of stability that are often quite difficult to assess in the field are systematically negatively correlated with impacts on biomass and impact on size structure.
Using bayesian methods and decision analysis as a rational basis to dealing with conflicting stock assessment results while providing management advice on stock rebuilding
TL;DR: In this article, a statistically rigorous, non-ad-hoc methodology is proposed to compute such probabilities: application of the sampling importance resampling algorithm to the available stock assessment data.
