Improving scientific advice to fishery management for resources of interest for Spain in Atlantic waters (IMPRESS) is a Spanish National Project. The underlying hypothesis of the project is that facing up with the identified stock assessment issues of the Spanish North West Atlantic species could substantially improve their fisheries management.
Within this context, the overarching goal of IMPRESS is to improve the scientific advice quality for fisheries management of resources of interest for Spanish fleets in the North West Atlantic. To achieve this goal the IMPRESS project will apply a sequential analysis following step by step the assessment process from the stock identification of the available data to the simulation and evaluation of management strategies

The research team is build by biologists and marine scientists. The two IPs are biologist with broad experience in mathematical and statistical models and assessment methods. This experience will be complemented with the external collaborators supporting the modelling work. However, due to the high mathematical and statistical level required from several tasks of the project a doctor in statistics has been hired.
