River old man fish is a name for us, unlike the common old man fish in bubbles (Gurdjieff perch pond bass), this fish has a long head that is very flat, a bit like a flat old man fish, mainly living in the clear flowing water stone crevices. It is a migratory fish, and after checking the data for a long time, it is basically determined that it should be a kind of Dufar. Above, according to the custom, borrowed from du niang.
This fish is a little less, Baidu pictures are also much less, looking for half a day on these two photos can see the characteristics. There are many other common names, the most common of which is the bighead fish.
This fish likes to lie in the stone crevices of the ditch or in the water flow at the bottom of the sand in winter, not afraid of people, generally even if you get closer, do not move it it does not run, some time ago to the chicken to weave an egg nest, cut wicker by the river, clear ditch shallow water sand bottom small rapids to see a dozen centimeters, lying on the side of the stone, the back is exposed to the water, I see this goods is stupid again, I found a wicker, drove it to the deep water flow under the ice, but also squeaked and twisted unwilling to move.
Now there are actually very few fish. The main one is too good to grasp, like shallow water, not afraid to catch, not to grasp, run out of a meter and stop there. If you want to say that there is a representative silly roe deer on the northeast mountain, there is this representative silly old man in this river, and they are all typical of the silly realm. The other one is that it was so delicious. The small fish in the northeast river, I have eaten this second to none, white and delicate fish meat without seasoning, with its own sweet, no fishy, fish roe to eat a bite of lips and teeth to leave a fragrance, if you taste carefully, a fish can drink half a pound of wine. Shanghai's most famous Songjiang perch, which is almost extinct, is related to it as a brother, and it is no wonder that this fish is delicious.
This fish has always been not much, when I was a child, the environment was good, I can see a lot in the summer, now it is rare to see once or twice a year, too few and no one catches it, one is not famous, so the price is low, one is to catch a few at a time too few to sell.
This fish can be farmed, that is, the seedlings are not easy to engage, there are scientific and technological workers have done experiments, the wild is also the largest river old man of twenty centimeters, artificial breeding can grow to more than thirty centimeters, several times larger than the wild, there is the potential to do pigs in the water.
