What should fish not have upon receiving to ensure quality?

To ensure the quality of fish upon receiving, one crucial aspect to check is the condition of the gills. Sticky gills are a sign of deterioration and poor freshness. Fresh fish should have bright, vibrant gills that are moist, indicating that the fish has been properly handled and stored. Sticky gills can suggest that the fish has been compromised, possibly due to being stored improperly or for too long, leading to a breakdown of quality.

Evaluating fish for characteristics such as bright color, firm texture, and proper cold storage conditions is essential for assessing freshness. Bright color indicates that the fish is fresh and has not begun to decay. A firm texture is also a key indicator of freshness; fish should feel resilient to the touch. Additionally, maintaining cold storage is critical to ensure that fish remains at safe temperatures to prevent spoilage. In contrast, sticky gills directly indicate a quality issue and should not be present when receiving fish.
