Stage duration/development based on temperature

[nleco...@gmail.com]

Good day everyone,

I have been using CMS for a while now (mostly to represent shrimp larvae) and I generally use the vertical migration module as the larval behaviour evolve with development. In the past, I have used various tricks to consider the temperature within larval development.

One limitation of the CMS for that purpose is the fix stage duration that is defined within the vertical migration file (along with depth distribution for each stage).

For example, if two particles are released the same day into the model and face different temperatures (higher temperature generally accelerate development) because they have divergent trajectories, they will have the same development (define in the vertical migration file). However, one can imagine that if particle 1 travelled in warmer areas, its development should be faster than a particle 2 facing colder water.

Before I start digging  into the CMS code, I was wondering if anyone has already developed a module or modified the CMS to consider a temperature dependent stage development?

Thanks for your inputs,

Best,

Nicolas
