Stick-slip and H-stability in Stochastic Simulations of Schools of Fish

The dynamics of a school of fish with noise are simulated both for applications to pelagic species of fish and as a model for a primitive organism. Methods from statistical mechanics and simulations are used to compute the potential in the associated Fokker-Plank equation for the density. Stick-slip behaviour is observed for some parameter values whereas for others H-stability yields either attraction or repulsion in the school.
