Ichthyop is a free Java tool designed to study the effects of physical and biological factors on ichthyoplankton dynamics.
It incorporates the most important processes involved in fish early life: spawning, movement, growth, mortality and recruitment. The tool uses as input time series of velocity, temperature and salinity fields archived from ROMS, MARS, NEMO or SYMPHONIE oceanic models (either files or OpenDAP).
The tool offers two running modes. The first one provides a user-friendly GUI for setting-up and running the simulation and visualizing the transport of virtual eggs and larvae, either creating animated GIF or exporting the trajectories to KMZ format (Google Earth). The second one is a batch mode that gives full power to computation. Both modes produce NetCDF output files that store information about the simulated dynamics of individuals (time, longitude, latitude, depth, length, etc.).
