Sustainably managing marine species is crucial for the future health of the human
population. Yet there are diverse perspectives concerning which species can be exploited …

Estimation of population abundances in the absence of good observational data are
notoriously difficult, yet urgently needed for biodiversity conservation and sustainable use of …

The spawning potential ratio (SPR) is a well-established biological reference point, and
estimates of SPR could be used to inform management decisions for data-poor fisheries …

The complexity and cost of assessment techniques prohibits their application to 90% of
fisheries. Simple generic approaches are needed for the world's small-scale and data-poor …

The theoretical basis of a new approach to data poor fisheries assessment, length-based
assessment of spawning potential ratio, has been recently published. This paper describes …

The National Marine Fisheries Service (NMFS) Cooperative Shark Tagging Program (CSTP)
was initiated in 1962 as a collaborative effort between recreational anglers, the commercial …

The European Marine Strategy Framework Directive (MSFD) requires European states to
maintain their marine waters in 'Good Environmental Status'. The MSFD includes 11 …

Numerous studies have now demonstrated that the most common method of ageing sharks
and rays, counting growth zones on calcified structures, can underestimate true age. I …

We provide a perspective on steepness, reference points for fishery management, and stock
assessment. We first review published data and give new results showing that key reference …

Surplus production represents the processes that affect sustainable fishery harvest and is
central to the ecology and management of marine fishes. Taxonomy and life history …
