Resumo: | ICCAT BFTWG completed the stock assessment using multiple stock assessment methods in 2017, and they are going to proceed with the MSE process: development of MP in 2018. It is well recognized that the performance results of MPs often depend on the design of the OM and its conditioning that capture the range of potential population dynamics. It is therefore critical to consider them carefully before moving to the development of MP, but this has been a monumental task given the complexity of ABFT. The ICCAT GBYP Core modelling group has developed the OM by incorporating the mixing between two stocks, and the trial specifications. However, the 2017 stock assessment raised a number of issues that may require further consideration for the OMs, particularly related to time varying catchability and selectivity, effective sample sizes for composition data and stock mixing dynamics that are limited information. Overall, we commend the work of the ICCAT GBYP Core modeling group for producing the current OM and framework for evaluating MPs. Our purpose in this document is not to criticize this work but to foster clarification and further discussion about key uncertainties that have emerged during the 2017 assessment.
