Abstract

To provide a means of relating laboratory and field bioassay results to natural populations a Monte Carlo mathematical model was modified to track the movement and survival of fish in a body of water, represented by a two-dimensional grid, subject to acidification stress. It was assumed that the fish (adults or the less mobile and generally more sensitive early life stages) can sense realistic gradients of pH, Al and Ca (or alkalinity) and to move to reduce the chemical stress. Effects of food availability and habitat preference on fish movement are also considered. A function for accumulation and repair of damage is implemented within the model to relate mortality to the variable exposure history the fish accumulate by moving in the chemically heterogeneous environment. The influence of the strength and sensitivity of fish avoidance behavior, the presence or absence of the refuge, and the timing of multiple pulses on fish survival, were evaluated. -from Authors
