An integrated model for aquaculture production, pathogen interaction, and environmental effects
This work develops, applies, and tests a methodology for simulating three key determinants of aquaculture carrying capacity: production, environmental effects, and pathogen interactions. Deterministic models for simulation of biomass production and environmental effects for fish and shellfish were c...

This work develops, applies, and tests a methodology for simulating three key determinants of aquaculture carrying capacity: production, environmental effects, and pathogen interactions. Deterministic models for simulation of biomass production and environmental effects for fish and shellfish were combined with stochastic host-pathogen models based on the Susceptible-Exposed-Infected-Recovered (SEIR) paradigm to build the Aquaculture, Biosecurity, and Carrying Capacity (ABC) platform.
