One of the main difficulties in the assessment of closed fisheries is the lack of catch data needed to perform a VPA; nevertheless, assessment is necessary in order to advise for re-opening in the framework of the Precautionary Approach. In this situation, advise is usually based on survey trends, and the problem of not knowing the true abundance is translated to the advise as an increase of un...

Abstract Recent efforts in ocean mapping of seafloor habitat have made data increasingly available. For bottom-dwelling and/or sessile species, there is often a strong relationship between population productivity and habitat, stock assessment models are likely to be improved by the inclusion habitat. Here, we extend recently developed spatio-temporal biomass dynamics model allow inform probabil...

Abstract Standardized catch per unit effort (CPUE) is frequently used to represent annual fish-stock abundance trends. In multispecies fisheries, the catchability coefficient differs depending on target strategy. Consideration of strategy in CPUE standardization therefore crucial improving accuracy and precision estimates. This study focuses potential a finite mixture model (FMM), where species...

Partially protected areas are now the dominant global form of spatial management aimed at preserving ecosystem integrity and managing human use. However, most evaluations their efficacy use only a narrow set conservation indicators that reflect fraction ways in which protection can succeed or fail. In this paper, we examine three case studies partially coral reef fishery systems to evaluate ben...
