We address the issue of wedding fisheries management to ecosystem management and in particular put forward ideas about the construction of neutral models for investigating community assembly rules and testing ecological hypotheses. To build a statistical model that mimics the North Sea fish community, we derived distributions of relevant parameters such as k-dominance curves, maximum length, log abundance, and species richness from survey data. Subsequently, abundance and distribution of 100 species was modelled in MATLAB based on the lognormal distribution of species abundance observed in the North Sea and varying assumptions of annual variations in μ, s and in the center of distribution. The hypothetical community was sampled annually to investigate temporal developments in emergent properties such as species richness and rarity indices and these were compared with survey estimates of the same 2 parameters. In addition, an old idea of using MSVPA and MSFOR results to fit multispecies Schaeffer Models was elaborated, and some ideas are presented on possibilities to simulate multispecies, size structured communities and on potential measures of level of exploitation of fish communities as a basis for ecosystem comparison
