Autumn equinox fishing hairy crab, you need to choose a water depth of not more than 1.5 meters, not shallower than 0.5 meters of water, with fresh small fish and shrimp, or animal offal as bait, the best effect;
Hairy crab, scientific name called Chinese river crab, is the species of freshwater crab in China, the most widely produced, the most widely distributed crab species, hairy crab is rich in nutrition, fat taste, convenient breeding, affordable price, favored by diners, known for not eating Yangcheng Lake, hair crab three points of fertilizer reputation;
Hairy crab is also called river crab, because of strong adaptability, so the north to the Yalu River, south to the Leizhou Peninsula, and even as far as the Ningxia of the Hetao Plain, can also find the traces of river crabs, in the seventies of the last century, China's aquatic research workers, the use of seawater artificial breeding crab seedlings, after more than ten years of research, Anhui ChuXian Fisheries Research Institute using brackish water artificial breeding crab seedlings have made significant progress, so far, freshwater ecological breeding of crabs, especially in inland areas of rice paddies and crab seedlings symbiosis of ecological breeding, the threshold has become very low;
The reason why the development of hair crabs is a simple explanation is because pure wild hair crabs, in nature, the stock is very small, because the chemical indicators such as water quality cleanliness and pH are very high, and even the demand for dissolved oxygen in the habitat waters is also more demanding; now the hairy crabs distributed in the north and south of the river are mostly artificially farmed crab seedlings, and then after the rise and fall of the irrigation basin, they fall into the wild waters, so most of the hairy crabs in the wild waters, physiological habits, eating habits, etc., completely follow the habits of farmed crabs So if we want to catch hairy crabs, or even connecting rods, we must follow the following two points.
The first point, the water depth of the hair crab group is about 0.5 to 1.5 meters
Hairy crab in the fry, the water quality requirements are higher, because the crab fry resistance to disease is poor, so more will be disinfected with lime water, after clearing the pond began to apply the basic bait organism, and will be appropriately put into cattle, pig manure to fatten, in order to ensure clean water quality, will be planted in the crab pond reed grass, water hyacinth, etc., to purify water quality; in order to ensure the survival rate of crab crab seedlings, crab fry breeding depth, generally will be about 0.5 to 5 meters;
Breeding crab seedlings, need to change the water regularly, generally every 10 days or so, you need to change the water; because once the concentration of dissolved oxygen in the water is less than 5MG/L, the hairy crab will appear lesions until death, in the wild, the crab group will be because of this characteristic, in the living water, aquatic weeds in the water habitat foraging, the water depth requirements are very harsh;
Therefore, when we fish for hairy crabs in the wild, the most suitable water depth should be selected between 0.5 and 1.5 meters, not too deep, not too shallow, which is also in line with the physiological habits of hairy crabs.
The second point is that the best bait for catching hairy crabs is to use fresh offal from animals or fresh small fish and shrimp
Hairy crab in the nursery period, every August to October, hairy crab into the molting stage, because crabs need to molt shell amplification body, so the demand for animal protein is unprecedented, artificially farmed crabs, will invest a large number of miscellaneous fish, animal organs as feed;
Therefore, when we fish in the wild in August and September, we mainly use fresh fish and shrimp, or fresh animal offal, cut into cubes, sections, hook, and directly into the water, no need to nest at all, you can attract a large number of hairy crabs into the nest to feed.
Finally, the hairy crab is a group of high crustaceans, the discovery of one, often means that there is a group of crabs, or a large group of crabs nearby, so do not worry about not catching a few, you can catch the crabs near the fishing point, especially near the fishing point there are rice fields, but also can be pulled for a long time, it is not difficult to fish for a long time.
