Predator-prey Dynamics In The Main Basin Of Lake Huron

This involves using existing age-structured assessment models for the main predators, updating these models for growth and bioenergetics, and review of information on predators for which there is no existing assessment, and if appropriate development of such assessments. We will then develop an age-structured prey fish assessment model that jointly uses estimates of prey fish consumption and data on prey dynamics (e.g., trawl surveys, hydroacoustic surveys, biological information) . This would be done using an assessment approach similar to statistical catch-at-age but with predation taking the role that fishing usually does. We will relate the resulting estimates of prey recruitment and mortality to possible causes, including predation and temperature.
