Estimating initial stomach content using stochastic simulation

The stomach evacuation model now in use when quantifying the predation from cod on Barents Sea capelin assumes that the evacuation rate is dependent on the stomach fullness after the last meal, which is not known in the field. The paper seeks to overcome this problem by fitting a simple feeding mode...

Description
Summary:The stomach evacuation model now in use when quantifying the predation from cod on Barents Sea capelin assumes that the evacuation rate is dependent on the stomach fullness after the last meal, which is not known in the field. The paper seeks to overcome this problem by fitting a simple feeding model for cod to the distribution of stomach contents from field data of individual cod stomachs.
