Seafood products, either wild or farmed, are highly perishable.
Their quality degrades rapidly due to the high content of water and
easily digestible macro-components. They are susceptible to rapid
deterioration and postharvest loss due both to microbial growth
and biochemical reactions aggravated by raised temperatures.
Other problems are caused by contaminants that are present in the
environment where the seafood are grown and harvested.
