International audience Norwegian spring-spawning herring (NSSH, Clupea harengus) is a key species in the food-web and for fisheries in the northeast Atlantic. NSSH has been the focus of many ecological and fisheries studies over decades and several hypotheses have been put forward to explain variations in its recruitment. We conducted an extensive literature review of the processes that have been hypothesized to control recruitment at age-2 years. From this review, we constructed a conceptual model to represent how these processes are interconnected. We then evaluated several of these
