v1 v2 1 1 == 2.7 Consumption == 2 2 3 Consumption is the intake of food by a group over the time period considered. It is entered as the ratio of consumption over biomass (''Q/B''). Absolute consumption computed by Ecopath is a flow expressed, e.g., in t/km² /year, while the corresponding Q/B would be /year. Consumption over biomass is entered on the [ [Basic input.htm|Basic input]] form.3 Consumption is the intake of food by a group over the time period considered. It is entered as the ratio of consumption over biomass (''Q/B''). Absolute consumption computed by Ecopath is a flow expressed, e.g., in t/km² /year, while the corresponding Q/B would be /year. Consumption over biomass is entered on the [wiki:BasicInput Basic Input]] form. 4 4 5 5 There are various approaches for obtaining estimates of the consumption/ biomass ratio (''Q/B''). They may be split into (''i'') analytical methods and (ii) holistic methods: … … 33 33 This relationship can be used only for fish groups that use their caudal fin as the (main) organ of propulsion. 34 34 35 ../Resources/Images/0300001C.png 35 [[wiki:Image 36 36 37 37 '''Figure 2.1''' Schematic representation of method to estimate the aspect ratio (''Ar'' = ''h2/s'') of the caudal fin of fish, given height (''h'') and surface area (''s'', in black).
