Modules Bioenergetic Module

The bioenergetic module in OSMOSE follows the principles of a family of models known as bioenergetic models. When activated, this module replaces the processes described in the corresponding sections (i.e., parts of the Processes Mortality, Processes Growth, and Processes Reproduction processes). OSMOSE implemented with this module is sometimes referred to as Bioen-OSMOSE.

The bioenergetic module assumes a triphasic growth model comprising a larval/post-larval phase, a juvenile phase, and an adult phase. It describes the flow of energy from Energy Uptake to New Tissue Production. After uptake, a part of the energy is assimilated and a part is mobilized. The mobilized energy is used to pay maintenance costs, to growth growth and reproduction costs, depending on the maturation status.

The maturation process depends on both age and size and is represented by a maturation reaction norm. Energy fluxes are influenced by temperature and oxygen concentration, allowing plastic responses to environmental conditions.
