No abstracts are to be cited without prior reference to the author.It is a rather common view that deeper involvement of fishing industry into stock assessment and regulation procedures should require (and may lead to) significant simplification of scientific approaches, models and methodology. Such a simplification is considered to be important in order to allow science and managers to use common notions, more understandable for non-scientific world. Fortunately it is not always the case. Situation with stock assessment of some important species in North-East Atlantic may serve as a good example of the inverse process. For several years in Norwegian spring spawning herring stock assessment two different approaches were used. One of them (SeaStar model) was based on classic likelihood functions what insured proper mutual weighting of signals from all available sources of information incorporated into the model. The second one (ISVPA model) stressed the point of robustness of analysis and included a number of ...
