compared with freshwater bass, sea bass is bigger, and it is divided into two species: white bass and black bass. Sea bass is long and thick, with rough scales, generally reaching 11 to 12mm and weighing 1.5 to 1.8 kg. Its upper jaw is shorter than its lower jaw and its mouth is sharp. The difference between sea bass and freshwater bass is not only reflected in the appearance, but also in the taste of their meat. The sea bass sold in the market are generally live, so you can ask the store to handle them when you buy them, while the sea bass, like most marine fish, is mostly chilled. From the taste when eating, the meat quality of sea bass is relatively "firewood", and because it is a marine fish, it has a heavy smell. However, the meat of freshwater perch is like "garlic clove meat", which is easy to disperse after steaming, but the meat is elastic, not fishy and more delicious. From the taste point of view, it is true that freshwater bass is better than sea bass. No matter whether it is returned perch or fresh water perch, it is very rich in nutrition, and perch has fewer fishbones, so it is also suitable for baby to eat after steaming.

Press the fish body with your fingers, and the elasticity means that the fish body is fresher; Don't buy perch with red tail, because it shows that the fish is physically damaged and will die soon after buying it.
