How to identify the quality of fish species
First, to see whether the specifications are uniform of the same kind of fish, those who come out of the pond with uniform specifications are generally more physically fit. Second, to see if the fish is glossy and strong, there is a layer of mucus on the body surface of the fish to protect the scales and skin from germs, so the body surface shows a certain luster. On the other hand, the body surface of sick and injured fish is lack of mucus and no luster, or some diseased fish have too much mucus and lose their luster.

Why pond fish lack oxygen in winter
This is because when the temperature drops, the surface water temperature of deep-water ponds, fertile water ponds and cage high-density aquaculture waters is lower than that of the lower layer, and the specific gravity of water is higher than that of the lower layer. As a result, the surface cold water sinks and the lower warm water floats, forming vertical convection of the water body. On the other hand, the water body of the deep water layer is anoxic or even anaerobic, and the anoxic and anoxic water body floats up, resulting in serious hypoxia in the upper water body. On the other hand, the vertical movement of the water body accelerates the oxidation and decomposition of residual bait and feces deposited at the bottom of the pond, and increases the oxygen consumption in the water body. On the other hand, winter is too much
