Area of Science:

  • Aquatic animal traceability
  • Fisheries science
  • Aquaculture technology

Background:

  • Urgent need for effective traceability in aquatic animal research, aquaculture, and trade.
  • Existing methods for fish traceability are diverse, but options for molluscs and crustaceans are limited due to practical challenges.

Purpose of the Study:

  • To review and describe various methods for tracing fish, molluscs, and crustaceans.
  • To assess the suitability of different techniques for research, aquaculture, and trade control.

Main Methods:

  • Review of external tags (Floy, Carlin, PIT tags) and chemical marking for fish.
  • Description of electronic devices, DNA profiling (genetic traceability), and chemical/biological stains for various aquatic species.
  • Examination of mechanical tagging, movement documents, and labeling for molluscs and crustaceans.

Main Results:

  • Diverse physical, chemical, and electronic marking methods exist for fish.
  • Genetic traceability shows high confidence for origin and paternity verification in fish and crustaceans.
  • Traceability for molluscs and crustaceans relies heavily on documentation and labeling, with limited physical marking options.

Conclusions:

  • Genetic methods offer robust traceability solutions for aquatic animals.
  • A combination of physical tagging and documentation is necessary for comprehensive traceability across species.
  • Standardized labeling and documentation are critical for controlling trade and ensuring product authenticity.
