三文鱼的品质并不是由单一因素决定，而是由鱼种、养殖或捕捞方式、新鲜度、脂肪分布、加工工艺、储存条件和可追溯性等多个因素共同影响。
Salmon quality is determined by a combination of factors, including species, farming or harvesting methods, freshness, fat distribution, processing, storage, and traceability.
- 鱼种（Species）
不同鱼种具有不同的口感、油脂含量和风味。例如，大西洋鲑、帝王鲑和红鲑都有各自的特点。
Different salmon species have distinct textures, fat levels, and flavors. For example, Atlantic salmon, Chinook salmon, and Sockeye salmon each offer unique characteristics.

- 全程冷链管理
Quality is also influenced by processing methods, including:
- Fresh (never frozen) or frozen handling
- Cutting and trimming techniques
- Packaging
- Cold-chain management throughout distribution
⸻
- 储存与运输（Storage and Transportation）
保持适当的冷藏或冷冻温度，有助于维持三文鱼的新鲜度、口感和品质。
Proper refrigerated or frozen storage helps preserve freshness, texture, and overall quality.
⸻
- 可追溯性（Traceability）
优质三文鱼通常具备完善的产品信息，包括：
- 鱼种
- 原产地
- 养殖或野生来源
- 生产批次
- 加工日期
High-quality salmon products are often fully traceable, with information such as:
- Species
- Country of origin
- Farm-raised or wild-caught
