I am looking for assistance in building a Mixed Effect Model to explain the presence /absence of fish movements, residency and migration (based on tracking) in response to environmental parameters which i have already collected. This study was completed over 2 years, with 50 tagged fish in 2019 and a further 60 50 tagged in 2020.
I have the days the fish were present, their whereabouts, their movements and i also have various environmental variables over the course of the study. The environmentals would be air temperature, rain, solar irradiation, sea surface temperature, salinity and tides.
I would love to incorporate all of this data into a Mixed Effect Model to determine which, if any, variables might explain the residency, movements or migration of the tagged fish.
Hope this helps
