Evaluation of the biomass limit reference point for Northern Cod (NAFO Divisions 2J3KL). : Fs70-6/2019-058E-PDF
"A conservation Limit Reference Point (LRP) was established for Northern cod (Div. 2J3KL; Figure 1) in 2010 (DFO 2010) and was defined as the average spawning stock biomass (SSB) during the 1980s. SSB since then has been lower and produced only poor recruitment. This reference point defines the boundary between the critical and cautious zones within the Precautionary Approach (PA) Framework (DFO 2009) and defines the stock level below which serious harm is occurring. At these levels the stock is considered to have suffered serious harm and the ability to produce good recruitment is impaired. At that time it was noted that the LRP should be re-evaluated once more data, particularly at higher levels of SSB, were available. Since then, there have been general increases in SSB from 2012 to 2017. Fisheries Management requested the current LRP be re-evaluated in accordance with the DFO PA Framework to determine whether the previous approach to adopting the LRP (as well as the LRP itself) remain valid"--Context (page [1]).
