Polovina's ECOPATH program for the construction of steady-state multispecies ecosystem models from fisheries data is presented. This new version called &quot;ECOPATH II&quot;, differs from the original, aside from being more user-friendly, in a number of important features, among othes: (1) use of a &quot;generalized inverse&quot; matrix routine allowing the system of linear equations used to estimate model parameters to be over- or slightly underdetermined; (2) estimation of (almost) any set of unknowns and not only of biomasses; (3) explicit consideration of respiratory, egestive and excretory losses (with defaults provided for inputs) and of the detritus pathways; (4) estimation of numerous derived quantities on species group or whole-system basis, such as gross and net efficiencies, trophic levels, food electivity, pathways and cycles involving any group and &quot;ascendency&quot; sensu R.E. Ulanowizc. The preliminary version of an empirical multiple regression model for the estimation from easy to estimate parameters of relative food consumption by fish populations is presented; this model provides reasonable values of the input into ecosystem models that were to date most difficult to estimate. An application to the coral reef ecosystem of French Frigate Shoals (Hawaii) is presented, along with some suggestions as to how this methodology could be applied to Kuwait waters.</style></abstract><accession-num><style face="normal" font="default" size="100%">3851122</style></accession-num><notes><style face="normal" font="default" size="100%">Conference ICES Theme Session on Trophic Models of Aquatic Ecosystems, Copenhagen (Denmark), Oct 1990International Cent. for Living Aquatic Resources Management, Manila (Philippines)Trophic models of aquatic ecosystems., iclarm, manila (philippines), 1993ICLARM conference proceedings.
