Anais Ancylus MOM 3 2 Manual http www ancylus net Preface Ancylus MOM is a software service to compute the holding capacity of a locality with respect to fish farming according to the Norwegian MOM system MOM is adapted to a range of fish species for a list see section 3 1 and should be applicable in all kinds of natural aquatic environments The holding capacity is computed from the following user determined limits that should not be crossed 1 A certain minimum oxygen concentration in the cages and 2 a certain maximum ammonium concentration in the cages securing good conditions for the fish in the cages and 3 a certain minimum oxygen concentration at the bottom securing reasonably good oxygen conditions for benthic animals beneath the farm The manual is arranged as follows Chapter 1 describes how to handle the program technically In chapter 2 Data Cards for input and results output are described The foundations for the computations may be found in reports and other publications listed in chapter 3 The most important publications can be downloaded from Downloads on Ancylus web site In chapter 4 it is shown how one may extract information relevant to the computations in MOM from current measurements at a location Section 5 deals with error handling and support and finally section 6 give a brief history of the MOM software Contents 1 How to use the MOM program A technical description 1 1 About Case handling in MOM
