Brown trout growth models

  • Hayes JW

These Excel visual basic models estimate brown trout growth rates, from time series data of water temperature, and under various feeding assumptions.

There are two types of models:

1. Bioenergetics-based models driven by temperature and food (invertebrate or fish diet), and with an optional invertebrate drift-foraging model front end;

2. Wet weight models assuming maximum invertebrate consumption – driven only by water temperature.

The model variants are described in the user guide, and are accessible as separate macros in this Excel workbook.
