Fish discards management: pollution levels and best available removal techniques

Area of Science:

• Marine Biology
• Environmental Science
• Food Science

Background:

• Fish discards and by-catch are significant environmental and economic concerns.
• Valorization of by-catch offers opportunities for new markets and value-added products.
• Contaminants in discards pose risks of bioaccumulation and adverse health effects in valorized products.

Purpose of the Study:

• To compile and analyze pollutant levels in European fisheries catches.
• To identify and evaluate the best available decontamination techniques for marine discards and by-products.
• To promote responsible and sustainable management of marine resources through safe by-catch valorization.

Main Methods:

• Compilation and analysis of pollutant data from European fisheries.
• Review of existing literature on decontamination techniques for marine by-products.
• Assessment of contaminant transfer from discards to valorized products.

Main Results:

• Identified key pollutants present in European fisheries discards.
• Evaluated the efficacy of various decontamination methods for marine by-products.
• Provided an overview of contaminant levels and decontamination strategies.

Conclusions:

• Effective decontamination techniques are crucial for the safe valorization of fish discards.
• Sustainable management of marine resources requires addressing contaminant risks in by-catch utilization.
• Further research is needed to optimize decontamination processes and ensure consumer safety.
