* \brief This is the base class used to calculate the migration of a stock within the model
|
| 17 : |
|
|
*
|

|
|
* This class moves fish from one area to another within the model. The proportion of the fish that move is calculated according to a migration matrix. The migration matrix is either specified in the input files (either directly or by specifying the ratio that move), or is calculated from a migration function, based on drift and diffusion parameters. Care is taken to ensure that the columns of the migration matrix will sum to 1, so that no fish are created or lost during the migration process. Once the migration matrix has been calculated, the fish are moved between the areas using a simple matrix multiplication function.
