Abstract
Modelling approaches in marine science is a controversial issue as no model is, or can be, a perfect representation of nature. Models can provide useful information for the dynamics of ecosystems and inform us about the likely consequences of human activities in fisheries and aquaculture. Applying a suite of dynamic models can be valuable predictive tools for modelling hazards transmission in fisheries and aquaculture activities in the Mediterranean Sea.
Highlights
The term “hazard” is often confused with the term “risk” and often the public do not generally differentiate between these two terms [1]
These dynamic models can contribute to develop and/or improve systems ensuring process efficacy and validation for hazard control by identifying “hot spot” zones and concentrations of hazard agents above certain limits, improve the effectiveness and efficiency of the controls performed by food safety Competent Authorities along the seafood chain, identify areas of hazard agents accumulation and contribute to the transparency and reliability of food safety in the Mediterranean fisheries and aquaculture production sites
The microbiological definition of hazard in Codex Alimentarius [2] is “inherent property of an agent or situation having the potential to cause adverse effects when an organism, system, orpopulation is exposed to that agent” whereas of risk is “the probability of an adverse effect in an organism, system, orpopulation caused under specified circumstances by exposure to an agent”
Summary
The term “hazard” (the intrinsic potential to cause harm) is often confused with the term “risk” (the probability of harm occurring at a given exposure) and often the public do not generally differentiate between these two terms [1]. B. A pelagic fish individual-based model (IBM) to describe the bio-accumulation of chemical and biological hazards.
