Abstract:
The Mussel Model consists of three parts: the Feeding, Physiology and Population models. The Feeding model describes the feeding behaviour of an individual mussel, and finds the energy intake from feeding and the associated costs. The Physiology model partitions this energy between the various activities: growth, reproduction, metabolic costs and storage. A sub-model within the Physiology model determines the spawning behaviour of the model mussel. The Population model uses the reproductive performance of an individual predicted by the Physiology model to estimate the rate of increase of a population composed of such individuals. A control run of the Mussel Model, with no toxic effects, is compared with an impacted but otherwise identical run, to assess the effect of toxins. The values of parameters for the Mussel Model are taken from a file provided by the user. Food concentrations can be described by a variety of annually periodic functions, or monthly values in a user-supplied file; the food supply is assumed to be the same each year. The effect of toxins on feeding behaviour is entered by the user, and a toxicity routine uses this information to establish toxicity parameters that govern the physiological effects of the toxicant. The Population Model uses a survival schedule in an additional file provided by the user.
