“…A2 B) that seeks to achieve a catch target of MEY based on an observation model that estimated current fishing mortality (F c ur ) from the age-structure of recent catches. The population status was determined from the equilibrium spawning biomass associated with the estimated current fishing mortality (Cordue 2012), where current fishing mortality is based on a modified catch curve analysis applied to age-composition data captured from the underlying biological model (Wayte & Klaer 2010).

“…In recent years, research on developing assessment techniques for data-poor fisheries has 54 increased, and a suite of tools is evolving for scientists and managers to assess and manage 55 stocks with limited data (Kelly et Klaer, 2010). However, many of these methods still require considerable amounts of data 57 from the fishery or the biology of the target species, including a time-series of historical 58 catch, catch-per-unit-effort (CPUE) trends, or information on the age structure of the stock, 59…”

“…As such, catch curves are instrumental tools for assessing stock status (e.g. Thorson and Prager, 2011) and informing harvest strategies (Wayte and Klaer, 2010) from a limited amount of data. For a population that is sampled in a single year, each age corresponds to a different year-class (with earlier year-classes being sampled at older ages), and mortality estimates may be valid only under the assumption of constant year-class strength (Robson and Chapman, 1961).…”

“…In reality, most of the assumptions underlying the catch-curve approach are violated (Dunn et al, 2002;Catalano et al, 2009), thus requiring modifications of the simple approach outlined above (Xiao, 2005;Schnute and Haigh, 2007;Wayte and Klaer, 2010;Thorson and Prager, 2011). One core issue that is common to all approaches utilizing catch-at-age data is that sampled individuals are pooled into discrete (integer) age-classes.…”
