An individual‐based model of the early life history of mackerel ( Scomber scombrus) in the eastern North Atlantic, simulating transport, growth and mortality
Abstract The main purpose of this paper is to provide the core description of the modelling exercise within the Shelf Edge Advection Mortality And Recruitment (SEAMAR) programme. An individual‐based model (IBM) was developed for the prediction of year‐to‐year survival of the early life‐history stage...
