Yellow croaker is a common food with diverse preparation methods—it can be made into sweet and sour fish, braised dishes, fish soups, and more, all rich in nutrients. However, many people are unaware of its origin and wonder: Is yellow croaker a marine fish? Let's explore this here.
Generally, deep-sea fish refer to species inhabiting depths below 2000 meters. Yellow croaker undoubtedly qualifies as a deep-sea fish. It comes in two varieties: small yellow croaker and large yellow croaker—choose whichever suits your preference.
Some yellow croakers are artificially dyed using chemical dyes like Yu Jin Huang, which can be harmful to human health when consumed.So how can we identify them when purchasing?
Identification methods:
Wipe the fish body with white tissue paper—dyed fish will leave distinct yellow stains. For frozen dyed yellow croakers, the ice surface may also appear yellow. Alternatively, soak the fish in water for about 5 minutes; dyed fish may turn the water a beer-like color.
Additionally, to determine freshness: Fresh yellow croaker typically has plump, clear eyes with transparent corneas, tightly closed gill covers, bright red gills, and clear mucus without odor. The flesh should be firm and elastic, with a straight body that springs back immediately when pressed. Scales should be intact, glossy, and tightly adhered to the body.
The primary distinction between river fish and sea fish lies in their habitats. Strictly speaking, river fish are freshwater species, including common varieties like carp, crucian carp, grass carp, silver carp, Wuchang fish, tilapia, and eel. Sea fish encompass species such as hairtail, tuna, large yellow croaker, small yellow croaker, horse mackerel, as well as salmon and turbot.
Regarding whether yellow croaker is a marine fish, it's important to note that for human absorption, there's little difference in nutritional value between deep-sea and river fish. The main variation lies in the distinct flavors of different species. Therefore, when purchasing, you can choose based entirely on personal preference without needing to focus on nutritional distinctions.
