River cod looks a lot like catfish, so there are also called mountain catfish, catfish, in fact, it has no relationship with catfish, it is a kind of fish in the cod family, this genus has a total of three kinds of fish, one is this river cod. One is the Russian Siberian short-tailed river cod, which is closer to this one in Xinjiang. One is the North American river cod, which is distributed in North America. We are the face value of the river cod genus. Above, the lady is hard
The river cod can grow to more than a meter, and it is a very fierce fierce fish, but I have never seen such a big fish. Eating habits and catfish is really similar, eat a variety of small fish that can be caught, of course, when you can't catch it, you can also take fish eggs and aquatic insects or something, if you catch up, it doesn't care about eating some fish and chicken offal, I heard that Xinjiang also taught river cod to eat feed. Wild river cod is afraid of heat, and in the summer they hide in the mountain streams to sleep, and they do not eat much, and they are happy when it is cold. This stuff must not be mixed with forest frogs and other small fish, unless you raise small fish just to feed it. River cod is a good fish for winter fishing, and it is very good for ice eye fishing in winter.
River cod is not happy, from fish eggs to commercial fish in the case of sufficient bait temperature to take two or three years, there is currently a research institution in Hebei is said to have been artificially farmed, but in the northeast whether this technology is available, it is unknown. I think it is possible to form a semi-artificial imitation natural farm with a mountain stream and increase the water surface, and there should be a sand bottom in the farm that is more than two meters deep in winter to simulate the natural spawning area, so that the river cod can naturally breed and grow naturally. If there are cold springs in the mountains and streams upstream of the water, the cod dormant will become less, and the growth rate will increase a lot.
At present, there is no artificial breeding of river cod, all breeding is carried out in research institutions, and the benefits of breeding cannot be discussed. In fact, it is a very potential fish, the main problem is that the Heilongjiang River Basin river cod production is not large, the distribution is relatively wide, the river cod is not very famous to the outside world, there is no market heat. So although the taste is excellent, especially the liver is a rare delicacy, some places can sell for twenty yuan, which is really a tyrannical thing. If there is a well-capitalized enterprise to dominate the market promotion, this fish minute will become synonymous with high-end luxury.
