DEB-codes for the Pacific oyster Crassostrea gigas (Bourlès et al. 2009), for the Mediterranean mussel Mytilus galloprovincialis (Casas & Bacher 2006) and for the blue mussel Mytilus edulis (Rosland et al. 2009) can be downloadable from this website (see below). Codes are either implemented in STELLA™ 8.0, an image-based modelling software produced by isee™ systems (see below to download a free version), or in Matlab.

In connection with these codes, Bas Kooijman is setting up a data base with code and parameters in the add_my_pet collection in the DEB lab. This code (see the mydata-subdirectory of add_my_pet) is standardised and uses DEBtool. It now has some 40 species (see Species.xls for an overview in the add_my_pet collection).


How to proceed with STELLA if you want to use it:
 First step. If you need STELLA, you can downlaod a free trial version of the software with isee Player (http://www.iseesystems.com/softwares/player/iseeplayer.aspx) which enables you to view, run, print and share STELLA models for free.
Second step. To download and save DEB-codes (files with .STM extension), click once with the right button of your computer mouse on the DEB-code and press "Save the link as".
Third step. With STELLA, you can then run the model with your own growth and environmental data.


The DEB model has been applied for various bivalve species (Van der Veer et al. 2006). Figure 3 illustrates in a very schematic way how the DEB equations have been applied and tested on two data sets on Crassostrea gigas (from Pouvreau et al. 2006).
