Which of the following is a sign of old fish?

• A. Bright, vibrant gills
• B. Firm texture and no odor
• C. Grey gills and strong odor
• D. Clear eyes and fresh scent

Answer: (C)

The presence of grey gills and a strong odor is a clear indication that the fish has aged and may not be fresh. Fresh fish typically exhibits bright, vibrant gills that indicate their health and freshness. When fish begins to spoil, the gills can turn grey due to the breakdown of pigments as the fish deteriorates. Additionally, a strong, unpleasant odor is a hallmark sign of spoilage, as this occurs due to the growth of bacteria and the decomposition of fish tissues. In contrast, fresh fish would have a subtle, ocean-like scent and firm texture, matching the characteristics associated with quality seafood. This highlights why grey gills and a strong odor are definitive signs that the fish is no longer fresh.
