The 29 estimators of natural mortality (M) that have been proposed for 'information‐
limited'fisheries are reviewed, together with a new alternative presented here. Each is …

The rule of thumb that fishing mortality to achieve maximum sustainable yield (F MSY)
equals natural mortality (M) has been both criticised and supported by theoretical …

Overfishing of sharks is a global concern, with increasing numbers of species threatened by
overfishing. For many sharks, both catch rates and underwater visual surveys have been …

Longnose skates may have a high intrinsic vulnerability among fishes due to their large
body size, slow growth rates and relatively low fecundity, and their exploitation as fisheries …

Sensitivity to overfishing is often estimated using simple models that depend upon life
history parameters, especially for species lacking detailed biological information. Yet, there …

The study of age and growth is a fundamental component of fisheries science with important
applications in fisheries management, conservation, and branches of ecology. This chapter …

The von Bertalanffy growth function is the model most widely applied to describe growth in
fish populations. Parameters describing this function usually are estimated from observed …

More than 33 skate species have been registered in the Southwestern Atlantic Ocean (SAO)

Natural mortality rate (M) is one of the essential parameters in fishery stock assessment,
however, the estimation of M is commonly rough and the changes of M due to natural and …
