Model Development for Fish Appetite by Siri Kildal Hansen
Explore the development of a model for fish appetite by Siri Kildal Hansen, focusing on motivation, literature study, mapping, modeling, parameter estimation, and simulation. Dive into factors affecting fish appetite, including endocrine regulation, external factors like photoperiod and temperature, and internal factors like hormones and peptides.
