Upstream inefficiency of adult migrants

Upstream inefficiency table from the Atlantic salmon Dam Impact Analysis model v67. When adult Atlantic salmon do not pass a dam, a proportion of those fish die, a proportion return to sea, and a proportion go elsewhere to attempt to spawn. These values are used in combination with the straying_matrix to spatially distribute returning adult spawners in each generation of simulations.
