The body of the arowana fish is laterally compressed, with a bulging back and a thicker body; it has a pointed head, a large and upturned oral fissure that is slightly tilted, a lower jaw that protrudes forward, and a maxillary bone that extends to the posterior edge of the eye. Sharp teeth of varying sizes on both the maxillae and stomatopods, the posterior margin of the anterior gill cover bone serrated with 4-5 large spines on the lower margin, and the posterior margin of the gill cover with 1-2 flattened spines; Siniperca chuatsi's scales are rounded and small, the body color is brownish-yellow, brighter, and distributed in many irregular patches. There is usually a brownish-black or reddish-brown stripe from the tip of the muzzle across the eye to the lower anterior part of the dorsal fin. There is a dark brown transverse band under the 6th-7th dorsal spines. The dorsal, caudal, and anal fins all have 2-4 brown circular spots in a continuous band. The dorsal fin is well developed, with stiff spines anteriorly and tall and rounded posteriorly. The pectoral, anal, and caudal fins are rounded. Its ventral and anal fins have sharp, hard bony spines in front, making it one of the most beautiful fish in the Heilongjiang River. It has a big mouth and sharp teeth, wide body and short tail, swimming up colorful, dorsal fins like stretching the crown, fins and bones as sharp as a sword and halberd, as if a battlefield is fully clothed with a general, looks fierce and dashing, handsome, robust and invincible. No wonder it is in the water rampage, there is an unstoppable dominance.
Normally, the Arowana lives alone, which is the **** nature of almost all carnivorous fish. The arowana has a strong adaptability to water temperature and is found in both the northern and southern water systems of China. The arowana is nothing more than a common fish that lives near the bottom of rivers and lakes where the water is clear, and is especially fond of hiding behind rocks underwater or in the midst of lush grasses. In the season of low water temperature in the fall and winter, it dives in the deep water to overwinter, and when the water temperature rises in the spring, it gradually swims to the food-rich water near the shore to look for food in the grass. The fish is mainly active at night, but during the day, it usually lies in rock crevices, tree roots and pits, and is less active. The Arowana eats very carefully, and after swallowing fish and shrimp, it will spit out the fish spines and shrimp shells, leaving only the meat in its stomach. This unique feature is rare among other carnivorous fish.
The breeding period of the arowana fish is at the annual water temperature above 21℃, and the optimal water temperature is 26-30℃. The breeding months of the arowana are different in different regions of the north and south, and the middle and lower reaches of Heilongjiang are the breeding season of the arowana in June and July every year. During the spawning period, Mandarin fish spawn in pairs in rivers and lake entrances where there is flowing water, which is their ideal spawning ground. By the time of the annual breeding season, the arowana fish swim fiercely against the water in pairs and form waves on the surface of the water.
The crayfish reaches sexual maturity in two years or more. But in the case of low natural resources and overfishing, in order to reproduce offspring and keep the race from going extinct, the parent fish may even reach maturity in one year. Early into the sexual maturity of the parent fish, due to the individual smaller, carrying less eggs, generally between 3-20 million, with the parent fish of the individual increase, the amount of eggs also increased.
Arowana eggs are floating, with large oil balls, semi-floating in running water, but sinking to the bottom in still water. Its egg diameter is 1.2-1.4 millimeters. Fertilized eggs hatch at a temperature of 20-32°C, with an optimum temperature of 25-30°C. The eggs can be incubated at lower water temperatures (21-32°C). In lower water temperatures (21-24°C), incubation takes longer. Fry begin to feed 48-60 hours after hatching, when they are only 0.46 centimeters in full length. When the juvenile reaches 1.65 cm in length it already has the appearance of an adult fish, but has not yet grown scales.
The arowana fish is not like those scavengers catfish, wyvern fish, GaYaZi, oxtail fish, don't care what, as long as it is meat will be swallowed. It is a fish that survives by eating live aquatic animals, and its main food is live fish and shrimp, which are hard to catch. But there are exceptions to everything, one year my brother and I in the Heilongjiang River to earthworm bait fishing, my brother actually caught up a more than 2 pounds of arowana fish. This kind of thing is rarely happen, just coincidence.
The arowana fry hatch out of the membrane 4-5 days later, it will open the mouth to feed, the bait is the plankton in the water, or other kinds of live fish fry. Different stages of the arowana's bait is different, young fish grow by eating other fish fry; when the arowana grows into an adult fish, the food is relatively extensive, eating some other fish fry, or small fish and shrimp. Some fusiform or elongated fishes are the target of the crayfish. Arowana fish is greedy, hungry and unable to find food, often will also be infighting, fighting, swallowing the same kind to maintain their own lives.
The arowana fishing is very interesting, every summer evening, standing on the river boulder to see the arowana fishing, but also make people feel thrilled, exciting, quite able to appreciate the ferocious habits of this fish.
When the sun is about to set, the surface of the river is like a sprinkling of broken gold, and with the elongation of the mountain's reflection, the light of this broken gold is less and less, and the riverside becomes cooler and cooler. Calm river surface flashed out of the stars, and gradually dense, like scattered with broken silver, dazzling, that is the white white driftfish can not stand the heat and hunger during the day, to the evening can not wait to come out of hiding in deep water, scrambling to leap out of the water to catch the flying insects in the air. They flap their tails to their heart's content, and after a few beautiful maneuvers in the air, they fall into the water with a "pop" and disappear. At this time, the arowana fish also appeared. They swam from the deep water to the shallow water where the white drifters are concentrated, swimming on the surface of the water, scrambling for food, crown-like dorsal fins, under the light of the setting sun, colorful, gorgeous.
Seeing the sudden appearance of the arowana fish, the white drifters were scared and fled around in panic, and the river surface, which was still rippling a while ago, suddenly calmed down, only to see a water ripple scattered all over the place. The fish opened its mouth wide and quickly chased the white drifters, accurately catching the slow-flying fish in its mouth and swallowing them in its stomach.
This is how the fish hunt. Because the arowana fish looks very beautiful, swims with elegance and grace, there is a beautiful legend.
A long, long time ago, there was a Herzhe fishing boy living on the Ussuri River. He lost both parents since childhood, living alone, very bitter. In his spare time, he played his beloved ukulele to relieve his boredom.
The lively sound of the harmonica ripples on both sides of the Jialing River, like a hundred birds chirping, like a million horses galloping, like a gurgling water, like the spring breeze, the deer drilled out of the dense forest probe to listen to the birds in the air to listen to the fish jumped out of the water to listen. There is an arowana fish hear happy place, even from the underwater jump up, jumped to the boat. The boy hurriedly scooped up a few scoops of water and poured it into the cabin, allowing the fish to swim freely in the water. The boy played the ukulele, and told the fish his grievances: "Everyone says that the bitter gourd is bitter, but I am even more bitter than the bitter gourd; the bitter gourd is even more bitter than the company of others, but I am lonely and alone, to whom I tell? Today and you make friends and companions, a cavity of words to you to tell ......"
The arowana fish seems to understand the meaning of the boy, shed tears of sympathy. The boy loved it even more and played the ukulele for it when he had time. One night, the little guy dreamed that a beautiful girl came to his side and said to him, "I love to listen to you play the harmonica, and I love you even more as a person, if you would like to marry me as a daughter-in-law, try to get the water-leaving treasure pearl of the thousand-year old koala in the river, and with it, I will be able to leave the water tribe and live on earth." The boy was so happy that he almost jumped up, and when he turned over and woke up, he realized that it was a dream. At that moment he saw the turtle-flower fish poking its head out of the water, so he asked the turtle-flower fish, "Was the dream I just had real?" The turtle-flower fish nodded three times at him.
The next morning, the boy cast a big net and caught the thousand-year-old koala. The sturgeon begged the boy, "If you let me go, you can have a pocketful of gold." The boy said, "I don't want anything else, as long as you have that pearl in your mouth." The koala said, "This is the treasure of the Water House, how can I give it to you!" Seeing that the koala refused to give him the water-removing bead, the boy intimidated it, saying, "If you don't give me the bead, I'll have to take your life!" Seeing that things were not going well, the sturgeon had to obediently spit out the bead and give it to the boy. The little man hurriedly took the pearl out of the water back to the fishing boat and put it into the mouth of the arowana fish. The arowana fish took in the pearl of water and stood up from the cabin, turning into a pavilion girl who looked exactly like the one the boy had dreamed of. From then on, the boy and the ao hua girl in the riverside built a new straw house, married, single-mindedly live a small life.
The news that the boy had married a beautiful girl reached the ears of the fisherman's bully, who found the boy's home, saw the ao hua girl, and immediately salivated, and hurriedly asked the boy, "Who is this girl?" The boy replied, "It is my daughter-in-law." Fishing bully viciously said: "poor boy, your parents owe me a debt, limit you must pay off tomorrow, can not pay off, have to this girl to my home to offset the debt." Said turned his head and left. The boy was so angry and anxious that he shed tears, and could not think of any good way. The ao hua girl smiled and comforted him, said: "all right, tomorrow let you pay off the debt is." The boy was surprised and asked, "Where are you going to get the money?" The ao hua girl is again a slight smile, she let the boy to the river to load back a bag of sand, with that treasure pearl a light, the sand suddenly turned into a pile of glittering gold. With this bag of gold to pay off the debt of the fishing bully.
The fishery barbarians failed in one plan, and another plan, he said to the boy: "The debt is paid off, but you violated the rules of the clan, marrying a daughter-in-law does not tell me the patriarch of a word, the penalty is that you have to give me three days to do a hundred fish skin clothes, or else you have to let the girl to my house as a domestic slave!" The boy went home and told the ao hua girl. The ao hua girl said, "How hard can it be, send it to him tomorrow." The next morning, the young couple came to the fisherman's house with a hundred pieces of fish skin clothes. The fisherman looked overjoyed, busy took over to put on, want to try fit? Unexpectedly, he just put the fish skin clothes on the body, all of a sudden the room collapsed, flooding, hundred see fish skin clothes into a hundred live fish, this a mouth that a mouth, the blink of an eye will be the fisherman to gnaw on the light.
From then on, the ao hua girl and the boy lived a stable, happy good life. Of course, this is just a beautiful story, which is impossible to happen in real life.
The aohua fish in Jialing River is the most delicious fish. Its meat stewed milky white, garlic cloves, like just mined alabaster, out of the pot full of house spraying, color and flavor, the entrance has a kind of indescribably wonderful feeling. Ao hua fish meat is not like catfish, fathead fish meat in the mouth face, not a little chewy, feel and other fish is very different.
Ao hua fish has fewer thorns and thicker meat, which is especially tender, and can be steamed, sweet and sour, or cooked with squirrel Mandarin fish, dry roasted Mandarin fish, pine nut juice Ao hua and other multiple dishes.
Arowana is a rare fish, and its price is naturally much higher than other fish. However, there are very few wild arowana nowadays, and most of the arowana sold in the market or fish market are farmed Mandarin fish, the flavor of which is naturally not comparable to that of wild arowana.
