Description. This program simulates the vertical movements of two species of oyster larvae (Crassostrea virginica and C. ariakensis) from spawning to settlement. The behavior of both species include stage-specific changes in behavior, a random component to simulate individual variation, and the ability to modify larval behavior if larvae swim through a salinity gradient. A more complete description can be found here (.pdf, 115 KB).

Fortran Model. Developed by Elizabeth North.
__Code (.f, 15 KB)

C++ Model. Converted from Fortran to C++ by Zachary Schlag.
__Code (.cpp, 15 KB)

Example animations can be found here. Zachary Schlag created these Flash animations. The graphics for the animations were created with a Surfer/Scripter program (see link for Scripter graphics programs) written by E. North.
