Hello, I am an italian MSc student from Padova university (Italy) and I am using Ecopath software version 5.1 to build a mass balance model of Northern Adriatic sea. It is my thesis and it is related to INCOFISH project (I am helped by researchers Luca Palmeri and Yuri Artioli) I have found a possible bug in the Ecoempire routine, so I wuold like to report it. When using Ecompire to estimate consumption Q from total mortality, asymptotic weight, habitat temperature, aspect ratio and feeding type, I obtain a different result than that given applying directly equation 19 (Ecopath User guide), which should be the equation used in Ecoempire. I have checked units of measure, and I am quite sure that the equation used in Ecoempire is different from the one that can be found in the User Guide (and in your article with Palomares) because result is really different. I have tried to do calculate Q with equation 18 too, and the result is the same as in Ecoempire, so the problem should be only in equation 19. So, is it a bug? Which result is the right one? Thank you!

When I do the deletion in Define Habitats dialog, it generates indexOutofBounds exception in the RemoveEcospaceHabitats?..method..

To reproduce

• Open a model
• Open Basic Input
• Enter a value for 'Biomass in habitat area'

The new value is no accepted; the old value will reappear
