1. The survival wisdom of African plovers.

In the inland waters of Africa, the most powerful aquatic species is crocodile. They rely on their huge bodies and ruthless hunting methods to become well-deserved overlords in the criss-crossing rivers and lakes. Surprisingly, in the territory of crocodiles, there is a species that can compete with it. In fact, it is a small fish with a body size of only about 10 cm-African Thousand Birds.

African plovers are small fish, but their numbers are amazing. In a river, the total amount of all other fish is less than half of them, which makes their survival relatively calm and beneficial. Because of this, they have become something to be reckoned with by other creatures in nature.

In the same living environment, why can the number of African sole fish exceed other fish? The secret lies in the unique breeding mode of African plover.

As we all know, fish lay eggs in the water and let it hatch. However, fish eggs face too many dangers in the water. Natural enemies such as big fish, waterfowl, otter, snake and crab will include it.

Survival is an extremely difficult thing. Big fish? The secret lies in the unique breeding mode of African plover. This is also the fundamental reason why the number of other fish is difficult to increase, until the small fish hatch into the water and keep shaking their tails. African plovers have their own way.

The same living environment, but their number is amazing, which makes other creatures in nature not to be underestimated. Natural enemies such as crabs will incorporate it into their own recipes. The most powerful aquatic species are crocodiles and snakes. In a river, make sure the eggs are always wet, in crocodile territory. However, it may not only be easier to survive, but also fish eggs will face too many dangers in the water. Don't stick to the rules. Eggs are attached to leaves half a meter above the water. Why can African plovers alone surpass other fish? Because of this, we chose the right leaves at a certain distance from the water as the delivery room, and did not hatch eggs in the water. African plover will search carefully, but it turns out to be a small fish with a body of only about 10cm. In order to splash water on the eggs on the leaves, it sticks its body tightly to the downward side of the leaves, almost isolating all natural enemies in the sky, whether on land or in water.

In the inland waters of Africa, a large number of African fish are absolutely guaranteed, and wisdom is a panacea to solve all problems. Then, the fish lays eggs in the water and lets it hatch. It will stay here all the time, waterfowl, and it will try its best to jump out of the water, otter.

During the spawning period, it will shine brightly, and there are populations that can compete with it. When it found a branch sticking out of the water. Then, put the eggs on it. It is precisely because of this unique incubation method that we strive to be novel and look for waters with big trees on the shore. Surprisingly, the total amount of all other fish is less than half of them.

As we all know.

African plover is a tiny fish, and this scale advantage makes their survival relatively calm and beneficial. They rely on their huge bodies and ruthless hunting methods to become well-deserved overlords in the criss-crossing rivers and lakes.

2. Tilapia is a cichlidae fish belonging to the genus Tilapia, and it is also a cichlidae fish that is not a real tilapia. The genus tilapia contains more than 100 species of fish, which were originally found in parts of Africa and the Middle East, but can be found in many other waters around the world today. Tilapia is both an ornamental fish and an edible fish. As a food source, tilapia has played a very important role in preventing hunger in some areas, because it is easy to breed, and it is a very good source of protein in hungry areas. Many people hope that tilapia can help end hunger and malnutrition around the world. This website is dedicated to tilapia as edible fish and keeping tilapia in fish tanks. TilapiaTilapia has been raised as food for more than 2500 years. Tilapia farming was limited to some areas in the Middle East and Africa for a long time, but it has become a worldwide industry in recent years, with Asia, South America and Central America as the main producers of tilapia. Tilapia is a very suitable fish for farming, because they grow rapidly and are very tolerant to water conditions. Generally speaking, they are very cold-resistant fish. Farmed tilapia is not really tilapia, but a kind of fish called tilapia, although in fact they are not tilapia. The most common farmed tilapia are Oreochromis aurea and Sarot tilapia. The value of tilapia as food fish has led them to be introduced into a large number of waters around the world. They have established their own homes in more areas by escaping from the fishing grounds where tilapia are raised. This has led to the situation that you can find tilapia in tropical waters all over the world today. Tilapia in an aquarium Tilapia is very easy to keep in an aquarium, which is the same reason that they are suitable for farming. All kinds of tilapia are sold in the aquarium trade, and there are many varieties called tilapia. Found in Oreochromis aurea and Saroya. Some of the most popular species are tilapia buttikoferi and tilapia mariae (tiger tilapia). Tilapia cichlids are suitable for all kinds of aquariums, whether you are a beginner or a senior aquarium manager. Tilapia can be kept in a long row of different aquariums, depending on what kind of fish you choose to keep. You can find a kind of tilapia suitable for almost any aquarium setting, because there are all kinds and large varieties with various aggressive levels. The only requirement for raising tilapia in an aquarium is that you have an aquarium of at least 40 gallons/150 liters. Larger species of tilapia need larger aquariums. Browse this website to find more information about how to raise and breed tilapia in an aquarium. = = = = = = = = = = = = = = The large-scale commercial farming of tilapia is almost limited to three kinds of fish: tilapia, tilapia from Mozambique and Staphylococcus aureus. Nile tilapia is the most commonly used fish culture species among the three kinds of tilapia recognized as having aquaculture potential. The culture strategy of tilapia ranges from simple to very complex. Simple strategy is characterized by little control of water quality and food supply, and low fish production. With the greater control of water quality and fish nutrition, the production cost and fish yield per unit area increase. In this range, the management intensity has a process from low to high. In the traditional pond culture of tilapia, proper environmental conditions are maintained by balancing feed input and natural assimilation ability of the pond. The natural biological productivity of the pond (algae, higher plants, zooplankton and bacteria) acts as a biofilter and transforms wastes through natural biological processes. The increase of stocking density puts forward higher and higher requirements for production system. Additional energy input in the form of labor, water exchange, ventilation and feed is necessary to maintain the dense system. With the increase of pond yield and feed rate, it is necessary to supplement aeration and some water exchange to maintain good water quality. For densities above 0/.5 kg per square meter/kloc-0, ventilation is usually required. At one point, the incremental return is not worth the extra investment and risk. The increase of system strength does not necessarily reflect the increase of profitability. All tilapia production systems must provide a suitable environment to promote the growth of tilapia.

3. Write a composition, not less than 300 words fishing, everyone knows. But I learned one thing when I was fishing. What have I learned? Let me talk about it. That day, my father and I went fishing. My father was lucky today, and the fish were hooked one by one. As for me, I don't have any fish. I don't even see any fish. All the fish here seem to have gone on holiday. After a long time, I gradually became discouraged. My father told me not to fish. But I don't want to waste the last minute. I insist. At this moment, I found my hands shaking and the fishing line straightened. I hold the fishing rod calmly. It's time. I'll pull the pole quickly. Wow, I caught a 15 cm tilapia. Although there was only one fish, this fish was twice as big as my father's, and I jumped with joy. In this fishing, I realized that persistence is victory.

4. What are the living habits of tilapia, also known as African crucian carp?

The body is flat, round and scaly, with large fins, hard spines and soft spines, and the caudal fin is slightly bent without bifurcation. Body color varies with species, environment and gonad development, and some body surfaces and fins show black spots or stripes, which change greatly during reproduction. Tilapia, native to Africa, is a tropical fish with more than 100 species.

In China, Mozambican tilapia, Nile tilapia, Oreochromis aurea, Onion tilapia, Rainbow Sparus, etc. It has been introduced from abroad and widely promoted. Tilapia generally inhabit the bottom of the water, and the main active water layer changes with the temperature of the water layer.

Tilapia requires high water temperature, and the suitable temperature range is 18~38℃, and it grows fastest at 28~32℃. When it is below 15℃, it moves slowly, does not eat or move, and is in a dormant state. Tilapia is an omnivorous fish that mainly feeds on plants. There are many kinds of food, including algae, tender grass, organic debris, benthos, aquatic insects and so on.

Under culture conditions, tilapia feed on organic debris, plankton, artificial bait, filamentous algae, stems and leaves of large plants, earthworms, dragonflies and shrimps.

5. Composition of Winter Lotus Pond 1 Winter Lotus Pond Judging from the seasonal temperature difference, there is no winter in Nanning. No, the light snow has passed, it is already snowing in the north, and the weather in Nanning is still more than ten or twenty degrees.

The golden sun shone on the whole pond, and the water was sparkling. The fish sleeping in the deep water are swinging their light bodies leisurely, swimming slowly from the lotus roots to the open water at the bottom of the bridge, enjoying the warm sunshine. Lotus has withered, leaving only scattered lotus leaves, most of which are reluctant to shed their green clothes.

Most of the fish in this pond are red carp, but there are also a few tilapia. Over time, the fish and dragons are mixed, and there are few pure red carp left. Most of them wear gorgeous clothes: red or black; Black characters on yellow background; The foundation is red, and some of them are like big painted faces in Beijing opera. The red carp in these ponds are not as delicate as the goldfish raised in the fish tank, nor are they as graceful as the goldfish. They are strong and fat, and they breed quickly.

No, as long as someone throws food on the water, it's like blowing a signal, and fish suddenly flock from all directions. In just a few tens of seconds, the quiet blue waves instantly glowed red, and the fish were frantically crowded, flapping and even trampled for food.

The calm water immediately became noisy, and the "rushing" waves hit and splashed the clothes of the tourists on the shore.

Suddenly, a big black guy emerged from the bottom of the water. It happened that the fish's head, wide mouth and long tentacles were suddenly scared away. This fierce big guy is the Egyptian tanghorn fish. After enjoying a perfect meal, it immediately sank like a submarine.

The beautiful scenery in front of the lake has been restored, but the red carp is much more cautious than before, and groups of people get together like a family. Compared with the fat red carp, the gray-headed tilapia is much inferior. The mature tilapia is heavy, but the tilapia in front of us is only two fingers big. They were dense and dark on the other side. They dare not join the team to grab food, and eat the leftovers scattered with the waves with satisfaction.

In the other corner of the pond, a beautiful water lily is in full bloom quietly, with round toothed leaves lying flat on the water. As the petiole extends from the root to the periphery, it is skillfully combined into a huge flower shape, surrounded by purple flowers. She is very narcissistic, like a medieval lady, spreading out a wide skirt, sitting in a corner of the banquet hall with reserved eyes, watching everything around her coldly. Ren Tianwai's clouds are rolling. The mango tree by the pond seems to want to join the game in the pond. The thick branches are desperately pressed to the water surface, and the thick leaves cover nearly one-third of the pond like a huge green umbrella. They live together, mango trees absorb water and flourish; ; Ripe fruits fall into the water and become delicious for fish; It's sunny in the south for half a year, and mango trees create a cool world for fish.

Remove fragrant flowers, crisp and sweet fruits, shaded leaves and green colors. Only in this way, whether standing, leaning, folding or lying down, can the true colors of the winter lotus pond be revealed.

Although boring, but also in various ways, although bleak but pregnant with vitality.

However, it only experienced the vitality of spring, the splendor of summer, the richness of autumn and the loneliness of winter.

Only in this way can we truly taste the vicissitudes of life! 3 Winter Lotus Pond □ Three Mu Zi 2004- 1 1-27 04:43 Collection: 0 Reply: 0 Click: 592 You have been sitting for a long time. The north wind cries.

Leaves far and near are shaken off, and branches are also shaken off. Occasionally, the bark cracks and creaks, and the sound is like a crow, which is heartbreaking.

You are sitting on the edge of the lotus pond, and you don't know the time, the cold, and which cold wind has gone with your cold heart. The lotus pond has been frozen, and the ice is lifeless.

Only countless lotus branches are connected in groups, and flags are about to fall. It used to be a green lotus leaf like an umbrella. It used to be a lotus leaf with dew the size of dates. Now you can't see her fairy-like grace at all, you can't smell the intoxicating lotus fragrance, and you can't imagine that there are white, fragrant and full fruits under her slim beauty.

In your eyes, she is an abandoned ugly girl with yellow face and wrinkled face. Just think of her as a fallen flower, plucked from the beauty's head and abandoned by the roadside. You may even think that she is yourself, full of beautiful hair, dying, and the tide is gone.

In the cold wind, your soul flew away again. Huang Lian is about to burst with your bones ... you think so. Brown dead leaves and fallen leaves should be the grave where your soul rests, the place where you sing poetry, the place where you live, and the place where you escape the storm of heaven.

You see, the lotus pond is a graveyard with countless small graves full of souls. Every soul is there, singing death to the accompaniment of the cold wind. 4 Meditation-Winter Lotus Pond Mood: Weather: Light a cigarette and let the music gently follow the wind, as if the fidgety heart was calm again? Accept the rain and dew, put aside all distractions and thoughts, and pull away from worldly things. The desolate lotus pond in front of us seems to be gradually turning into the green of the past. Maybe you should warn yourself that although the lotus standing proudly in the moonlight has a muddy and uncontaminated artistic conception, the once green lotus leaf has to bow its head under the ruthless destruction in winter. How far do you have to go to feel the touch? Everything is frozen or disintegrated. Can I only approach such a distance and long for baptism? My heart has been listening to the distant notes of love, and the complex reality is so profound that I can feel and appreciate the philosophical thinking about the word "life" with a sincere and serious heart.

I have found enough, haven't I? I will give you extra points.

6. Fairy Tale The story of the old man and the fish "Feng Wan Lake is full of fish and shrimp, and Feng Wan Lake is a fairy tale!" This statement is described in Changwu's book, which is what I want to say: I once built a resort in Feng Wan Lake called Gyironburg, and I bought a lot of tilapia, which was only fifty cents a catty.

So I thought, "The eighteen eccentrics in Yunnan and the one in Southwest Guizhou are as cheap as dried vegetables." In addition, it is poetic to go fishing in a place called Tianshengqiao in Feng Wan Lake, where many things are magnetic, rational and fairytale.

All this, Feng Wan Lake on the Hook will tell you, and so will the fish in Feng Wan Lake. Fairy Tales Feng Wan Lake In the 1990s, Guodian built a high dam and sluice to store water at a place called Tianshengqiao on Nanpanjiang River. Overnight, the plateau emerged from Pinghu with a coastline of more than 2,000 kilometers, making it one of the five largest freshwater lakes in China.

The millions of power stations behind Tianshengqiao Dam have made the hearts of Guizhou, Guangxi and Dashan, which have been sleeping for many years, pounding, a new compilation of rare fairy tales! The story in Changwu's book is divided into two parts, one is a historical story, which is legendary. Part of it is the true story captured by the author in Feng Wan Lake, which makes people feel as if they were there.

Historical stories, mainly collected in the series "Maybe You Won't Believe", are ups and downs, interesting and fascinating. The core content of historical stories is actually the story of people and fish.

Like an Oscar? Just like the story of "Mermaid in Love" described by Wilde in "The Fisherman and His Soul", mermaid is a man's spring dream, which fishermen always want, even if they give their souls. Mermaids have various customs, but they have no "soul", and their hopes are pinned on fishermen.

All the stories described in this book are fascinating and touching stories of people and fish. "Fish Growing on the Mountain" describes the ancient fish fossils such as arowana, Guizhou cod, bow-fin fish, Xingyi flying fish, etc. from historical rock formations. It is amazing that things have changed and the fishermen have changed. The Hook of Yelang Man shows the "hook model" 2000 years ago, which shows the long history of human beings and fish. It can be seen from the fish dam catching tigers that the ancients set fence traps, lit torches and raised kitchen knives to cut fish; In "Lazy Rod", you will see such a magnificent scene: "From a distance, under the shade of green trees, a long row of fishing rods and lively fish are really rare scenery"; In the record set by the scale hook, fisherman Wang Yingkuan fished with the scale hook: "There are a group of big fish moving, fighting like a group of buffalo that can't stand the heat, rolling in the pond ..."; In addition, there are "heroes in fish" with seven hooks hanging on their bodies, and "divine fish" in the sinkhole in "Hooking a big fish", all of which are full of fairy tales.

Another kind of magnetic fishing ground is the true story of Changwu fishing by himself by the lake of Feng Wan. As a journalist and writer, Chang Wu is very busy, but Feng Wan Lake seems to be a gravitational electromagnetic field, which makes him make phone calls like a torpedo.

I used to be a fisherman. The stories of "fishing" written by Chang Wu were so real, so attractive and so magnetic that they caused countless echoes. I felt the generator in my body beating wildly. Fishing friends in Shanghai are still hooked and lured by tilapia from the Nile in Africa. He lost his business and came all the way to walk the fish, which made him unforgettable: "I remember the feeling of catching the big tilapia for the first time, just like the feeling of dating my girlfriend for the first time, mysterious, nervous and full of expectations."

Old people in Beijing sang late in Xingyi. He overheard a fisherman walking a fish in Yunnan and found that the fish was slender, with a silver front and a flat and black back. He thought that when he met a "water monster", he was actually bitten by a white striped fish and a tilapia. Hearing this story, he bought a boat, fished in Feng Wan Lake for three years, and made the fish into rubbings for preservation.

Living by fishing is like a duck to water. When he was young, he would arrange hooks in the river every night. When he paddled the bamboo raft to the shore, there was always a girl waiting to catch his kiss on the shore. Now that I am old, I often lick rhubarb dog on my hands and face.

After getting drunk due to a brain tumor, he chose to build a fishing house in Lake Feng Wan for five years. As a result, he went to the hospital for reexamination and found nothing unusual. He said, "If you lift the fishing rod, you can throw away the medicine pot." .

In addition, the stories of the old osprey and the small harpoon are equally wonderful. They became attached to each other because of the hook "fight", so they killed pigs and fished, slept in the grave together, and were poisoned by mosquito killer, but they still saved their lives. In addition, the story of fishermen in the south releasing their fish at the source of the Pearl River, and the fishermen who love smoking pipes and fishing drugs are also full of magnetism; In addition, the story of a fisherman who accidentally fell into the lake with a fishing bag on his back, a fisherman caught in a fishing line and a dead fish dragged into the lake is all sad and regrettable.

Fish of Philosophy From the hook of Feng Wan Lake, I saw not only sea poles and hand poles, but also the protection of herring, tilapia, mullet, pig-billed fish, sesame sword, red fish and many other fish, and saw that Feng Wan Lake is a rich fish museum. I also saw the historical and cultural Lake Feng Wan: I can vaguely see the footprints of Xu Xiake's Pan Jiangkao, and Meng Huo of the Romance of the Three Kingdoms series also took pictures here. Yi dance, known as the "Oriental Tap Dance", once danced on the shore, and sang with eight tones, known as the "living fossil of music", and once performed by the lake.

However, what I want to emphasize here is that the fish described by Tao Changwu is still a moral fish and a "philosophical fish". Fishing should have "fishing virtue", which is mentioned by Chang Wu in his book.

Fishermen should abide by the minimum fishing rules, such as caring for the fishing environment in the wild, releasing small fish when they catch them, not swearing if they don't catch them, and not urinating in the lake. Chang Wu throws a series of hooks in the article, which brings us thinking: what is it that people catch? Are people fishing, or are fish fishing for people? Who caught who? Fishing should be fed to the pond, bait should be paid and paid in advance, which may be the truth of "the fisherman benefits and mutual benefit"

What deserves more attention is Chang Wu's divergent tendencies in Jiang Shang and Zhuang Zhou. There is a mystery about Jiang Taigong's fishing: "It is to find opportunities to get ahead, or it can be said that Jiang Shang is putting on a show, and he doesn't really want to fish."

Looking at the small fish coming and going leisurely from the Zhuangzi, I think it is the pleasure of fish, and I envy it.

7. I am a fish 3 composition [I am a fish 3 composition] Since I also had the same experience as Sasha, my body has turned red, including those who are more innocent than me! Another day, I am a fish. I looked through the transparent glass and saw two moving "things" (actually people! ) I secretly listened to,,,,,, "Wow! Boss, this fish is really beautiful! I know you have your own secrets. I'm here to buy 200 red croaker, 200 lanyu, 100 tropical fish from you, and then,,,, ""Hey! All right, all right! You are also an old customer here, so we give you a discount! Every fish in 3 yuan, we usually sell it to 4 yuan! Ha ha ha ha,,,,, ""all right! I talked to you about this business! Haha! " The two men laughed outside the fish tank. I know from their mouth that he turned the chemicals we used into red and sold them to others! Hey! Now I know that people are so horrible! Today, I want to find Sasha, but I can't find her anywhere! I thought: Sasha will never be taken away again! Thinking about it, I found something touching my tail. I turned my head and saw only another friend of Sasha's. I asked him what happened. He said in a panic: "Sasha, it was dug away by the net!" " ",,,,,I am a fish. 3. Pupils' 400-word composition (/).

8. Write a composition to introduce the beginning of Huang. 1970, Huang was born in Hekou commune, baishan city, Jilin province. His parents both graduated from university, his father worked in a factory and his mother was a doctor. Although it is hard, his life is full of laughter, which provides a subtle help for him to engage in comedy performances in the future.

When Huang was in middle school, he liked to skip classes and often made small moves in class. He has never given much thought to his future life planning. When he was in high school, his father introduced him to a job of burning boilers because his grades were average and he had no hope of entering the university. Although Huang is playful, his IQ is not bad at all. Later, he suddenly woke up and tried to be admitted to the Department of Biochemistry of Jilin University.

When he was in college, Huang left his hometown for the first time and came to Changchun, the provincial capital. On the way to Changchun, he will never forget it. At that time, he took the 1 1 hour train, which was a station ticket. The long journey is too tiring for Huang.

Well, it's a bit like the busy Spring Festival travel rush peak now: in the crowded train carriages, there is a mixed smell of wine, sweat, cigarettes and various foods. He was so sleepy that he lay under the seat.

Come down, or climb onto the luggage rack to sleep for a while. These life experiences have accumulated rich artistic materials for Huang's later comedy performances.

In people's impression, science students are often quite normal, but it is wrong to look at Huang in this way. When Huang was in college, he liked telling jokes, telling jokes and performing programs. Wherever he is, laughter will follow. Humor is sometimes an invisible cohesion. After five years in college, he won a good popularity with humor and became a monitor for three years.

No one would have thought that Huang, who is now famous for his humor, was obsessed with philosophy in college. He is interested in philosophy because there are too many puzzles in his life when he grows up, in order to explore the meaning of life.

Justice and value, he tried to find the answer in philosophy. In the 1980s, when western philosophy and psychology were very popular, he stayed alone in the library and read many philosophical books, such as Kant, Nietzsche and Schopenhauer.

He has read all the works of Sartre and others. Especially Nietzsche's philosophical works, which he likes very much.
