There are currently no models to estimate F/FMSY for data-limited stocks that are commercially fished with dome-shaped length selectivity. Thus no catch advice in ICES-category 3.1 - with MSY objective - can be given for these stocks. An existing methodology will be expanded to be applicable to such stocks. With an F/FMSY estimate from this model, and the biomass index from the WOT IJsselmeer survey, catch advice with MSY-objective can ultimately be given for the IJsselmeer stocks of pikeperch and perch. Thus, the return on the WOT survey can markedly be improved.
