- Development of rapid, cost-effective methods to measure fish freshness is ongoing, yet sensory assessments remain widely used.
Integration of Cultured and Captured Fish
- Limited supply of fish necessitates closer integration between cultured and captured fish trades to reduce waste and improve quality.
- Wild fish typically possess superior attributes like fresh aroma, skin iridescence, and higher levels of n-3 polyunsaturated fatty acids compared to cultured fish.
Cultured Fish Control
- Cultured fish benefit from full production chain control and can be consistently available in the "Extra Freshness" class.
- Qualitative traits can be manipulated through dietary adjustments focusing on feed quality and quantity.
Health Benefits of Fish
- Fish serves as a healthy nutritional food option, vital for human health if produced safely and kept fresh.
- "Farm/sea-to-table" policies advocating good manufacturing practices and HACCP implementation are necessary for safety and quality assurance.
Quality Assurance and Certification

Quality Attributes of Seafood
- Seafood quality is characterized by attributes such as commercial size, organoleptic properties, and nutritional composition.
- Factors influencing quality include environmental conditions, species-specific traits, and handling practices throughout the supply chain.
Perishability of Seafood
- Fish is among the most perishable food types; post-mortem biochemical processes significantly affect quality and shelf-life.
- Conditions affecting freshness loss include temperature management, sensory characteristics, and biochemical changes during storage.
Wild vs. Cultured Fish Characteristics
- Cultured fish often exhibit higher fat content and different taste and aroma profiles compared to their wild counterparts.
- Differences in fatty acid composition arise from dietary variations, with cultured fish reflecting the feed characteristics.
- Wild fish typically have a higher concentration of certain beneficial fatty acids but are more susceptible to spoilage than cultured varieties.### Seafood Safety and Quality
- Seafood safety and quality are impacted throughout the distribution chain, primarily due to inadequate harvesting and handling practices.
- Good Manufacturing Practices (GMP) are crucial for maintaining safety and quality in aquaculture, post-harvest handling, storage, and processing.
Codes and Regulations
- The Code of Conduct for Responsible Fisheries (FAO, 1995) and Codex Standard for Fish and Fishery Products (Codex Alimentarius, 1999) guide seafood safety and sustainability.
- A Draft Code of Practice for Fish and Fishery Products is undergoing revisions to enhance safety standards.
Freshness Concept
- Freshness in fish refers to its quality being similar to that of living fish, with various factors influencing its gradual deterioration post-catch.
- Freshness classification includes immediate freshness (t=0) and how it changes over time (t>0).
Impact of Temperature
- Optimal refrigeration is essential for extending shelf life, with a significant difference observed at various temperatures (e.g., sea bass shelf life at different temperatures with ice covering).
- High refrigeration temperatures slow down post-mortem biochemical changes and bacterial activity.
Quality Assessment Methods
- Sensory evaluation is commonly used to assess fish quality, measuring attributes via sight, smell, and taste.
- Various assessment methods include the EU's quality grading system and Quality Index Method (QIM), which evaluates fish based on visible characteristics, odour, and texture.
Microbial Concerns
- Fresh fish is naturally free of bacteria, but contamination often occurs via skin, viscera, and gills during handling.
- Total Viable Count (TVC) typically ranges from 10² to 10⁶ cfu/g, though it doesn't predict freshness effectively.
Harvesting Practices
- Proper management of harvesting and killing procedures is critical to minimize stress on fish, which significantly affects quality and safety.
- Stress during capture (e.g., trawling) can degrade fish quality, while best practices in aquaculture can mitigate these issues.
Icing and Refrigeration Techniques
- Icing fish at sea and maintaining low temperatures during distribution is vital for maximizing shelf life.
- The recommended fish-to-ice ratio for preservation is generally around 60-70% fish to 30-40% ice.
Handling and Processing
- Fish must be processed under hygienic conditions to prevent contamination, particularly during gutting and washing.
- Regular monitoring of personal and water hygiene is necessary to ensure safety throughout processing.
Regulatory Compliance
- A mandatory Hazard Analysis Critical Control Points (HACCP) system must be implemented from harvesting to consumption to manage fish safety.
- Compliance checks include continuous temperature monitoring and regular inspections to avoid substandard quality entering processing lines.
Conclusion
- Ensuring seafood safety and quality requires stringent control through harvesting practices, proper storage temperatures, hygiene management, and quality assessment methods.
- Effective adherence to established food safety guidelines and continuous improvements in handling practices are essential for maintaining high seafood standards.### Catching and Handling Methods
- Pre-slaughter and slaughter stresses impact fish quality, influenced by catching methods and storage conditions.
- Observations of fish and fillet quality include physical injuries, color changes, and flesh gaping.
- Key technological properties assess rigor mortis development, texture attributes (firmness, cohesiveness, elasticity), and water holding capacity.
- Freshness and spoilage indicators: K value, dielectric properties, biogenic amines, and oxidation products like malonaldehyde.
Cultural Standards
- FAO's Code of Conduct for Responsible Fisheries emphasizes production quality over food safety or labeling.
- FEAP's aquaculture guidelines highlight farm hygiene, healthiness, and environmentally friendly practices.
- Factors affecting quality and safety: genetics, management practices, environmental conditions, dietary factors, and handling methods.
- National Codes of Practice can be developed based on the aforementioned standards.
