2. Why does the catfish I bought have black spots on its body?

I went to buy catfish before and saw two kinds, one without spots and one with spots all over the body.

Catfish has an elongated body, a flat head, and a laterally flattened tail. The mouth is small, with the end just reaching below the front edge of the eye (the end reaches the rear edge of the eye in the case of the large-mouthed catfish). The lower jaw is prominent. The space between the teeth is thin and velvety, and the jaw teeth and pear teeth are arranged in a curved band-like shape. The pear tooth band is continuous, and the middle of the rear edge is slightly concave. The eyes are small and covered with a membrane. Adult fish have two pairs of barbels, the upper barbels can reach the end of the pectoral fin, and the lower barbels are shorter. Juvenile fish have three pairs of barbels, and one pair of chin barbels begins to disappear when the body length reaches about 60 mm. Catfish are mucus-rich and scaleless. The dorsal fin is very small, without hard spines, and has 4-6 fin rays. There is no adipose fin. The anal fin is very long, and the rear end is connected to the caudal fin. The body color of catfish is usually dark brown or gray-black, with slightly dark cloud-like spots.

3. Are catfish with yellow and black spots and ulcers raised in stinky ditches? Are such fish not edible?

The ulcers may be caused by injuries during the capture and transportation process. It is not necessarily related to the water quality. However, some catfish are now raised in places with poor water quality. Hey, eat them with your eyes closed. There are too many harmful things in food. It doesn't matter if you eat less.

4. Can yellow catfish be eaten? Look at what I caught in the creek behind my house. There are more than 20 black-spotted catfish, but only one is yellow.

Catfish are generally gray-black with irregularly sized patches on their bodies. The golden catfish is due to a genetic mutation during its growth.

No problem, you can eat it, no difference from the black one
