TL;DR: The methods used to develop catch rate based indices of relative abundance for the school shark Galeorhinus galeus resource off southern Australia are outlined in this paper, which are based on fitting generalized linear models to catch and effort data for several regions in this fishery.

TL;DR: The Southern and Eastern Scalefish and Shark Fishery (SESSF) is a complex multi-species fishery, with 34 stock units under quota management, for which a harvest strategy framework was developed in 2005 as mentioned in this paper.

TL;DR: The status of the resource, as reflected by the ratio of present to virgin pup production and total biomass, is sensitive to the assumed level of movement between the stocks in New Zealand and those in Australia, with lower values corresponding to higher levels of movement.

TL;DR: Simulation of the effects of length-selective fishing mortality on the mean length of sharks in the wild population for age-classes 2–16 years were simulated for a range of levels of hook and gillnet fishing effort, and demonstrated how the magnitude of the von Bertalanffy growth parameters L ∞ and t 0 tend to increase and K tends to decrease as gillnets fishing effort increases, and hence explain how these types of biases can occur.

TL;DR: In this article, the authors used the Management Strategy Evaluation (MSE) approach to assess the benefits of alternative harvest strategies to set annual Total Allowable Catches (TACs) for school shark (Galeorhinus galeus) and gummy shark (Mustelus antarcticus).
