Historically, chemical and microbiological contaminants have been regulated in very different ways. Rather than regulating each type of microorganisms to a specific concentration, regulators have established a zero tolerance goal for microbiological contaminants and have used indicator organisms, particularly fecal coliforms, to show the possible presence of microbial.

General types of population models include surplus production, delay-difference, age-based, and length-based models (see Chapter 5 for specific references and more detailed descriptions of the models used in this study).

They rely on rates of change in biomass and productivity that can be calculated based on information about yield from fisheries, recruitment, and natural deaths.
