Query: How can I tell if trout is fresh?
Context: Fresh trout should have clear, bright eyes and firm, shiny flesh. The gills should be bright red and the scales should be tightly attached to the skin. If the fish smells fishy or has a slimy texture, it may not be fresh and should be avoided. When buying trout, it is important to choose a reputable seller and to ask questions about the fish's origin and handling to ensure that it is fresh and safe to eat.
