CATDOLL : CATDOLL: What are the diurnal habits of fish? What are the eating habits of carp?

1. What are the diurnal habits of fish?

, Midnight [about 00:00 ~ 04:00] the fish seem to be resting, and basically there are no fish.

2. At dawn [around 04:00-05:00] the fish have a short feeding spree.

3. When the sun rises [around 06:00-10:00], fish like to forage for food. This is their breakfast time and most fish eat.

4. Noon time [about 10:00-14:00] Fish take a nap, and there is rarely an urgent need for food during this period.

5. Afternoon snack [around 14:00-15:00] Fish have a short feeding spree.

6. Scramble for food in the evening [about 16:00-19:00] Fish like to forage for food, which is the dinner time for fish.

7. Just before midnight [around 21:00-22:00] fishes have a short feeding spree.

8. Fish like to eat when the waves are rolling, and they rest when the sea is calm!

9. Before the wind starts, stop it!

2. What are the eating habits of carp?

Wild carp tend to eat animal bait when they are young, but prefer plant bait when they become adults. In winter, early spring, late autumn and other seasons with lower water temperatures, carp tend to prefer animal food, while in summer and high temperature seasons, they prefer grain-flavored vegetarian food.

3. Fish stratification and their habits?

For example, crucian carp and carp mostly swim in the lower water layer, so we divide the fish species that live and swim in the bottom of the water into bottom-dwelling fish. Silver carp, bighead carp and black carp mostly swim in the middle water layer and the upper water layer. For example, the Asian dragon fish in Southeast Asia only swims in the upper water layer;

On the one hand, the physiological habits of fish determine the water layer where fish live, swim and inhabit under normal circumstances; on the other hand, on this basis, fish schools will change due to objective environmental factors and will not be fixed in a certain water layer;

Crucian carp is a bottom-dwelling fish, which is a cognition based on normal conditions. However, once the water temperature, water pressure and dissolved oxygen change, bottom-dwelling fish will not stick to the water layer, but will leave the original fixed water layer. At this time, the water layer where the fish leave the fixed water layer is located is called the fish layer.

The water layer is fixed, but the fish layer is different. The specific location of the fish layer depends entirely on the changes in the water conditions (including subjective and objective factors).

4. What are the eating habits of silver cod?

Silver cod generally live in the near-surface layer at a depth of 0-2740m. They are cold-water bottom dwellers. Their eggs are oceanic floating eggs. After hatching, the young fish mainly live in the middle and upper layers. As they continue to grow, they gradually migrate from the diving waters to the deep sea. Adult silver cod mostly live in water depths of 600-9042 feet. They live close to the seabed and usually exceed the sandy bottom. Silver cod are omnivorous fish, mainly feeding on shrimp, squid, worms or small fish. Their weight only increases in the first ten years after hatching, and they generally reach sexual maturity within 6 years.

5. What are the eating habits of butterfly carp?

Butterfly carp like to eat feed with high protein content. Breeders can choose animal feed, plant feed or artificial feed. Butterfly carp need to be fed three times a day, and do not feed too much. It is best to ensure that they can eat until they are 70% to 80% full.

The butterfly carp not only has a beautiful name, but its tail fin is even more beautiful, just like a butterfly, very elegant, so it has the beautiful name of butterfly carp. Although the whole body is white, it looks colorful under the colorful lights and is highly ornamental.

6. What are the living habits of fish in rivers?

The main purpose of fish swimming around underwater is to find food, because this is their only means of survival. Fish are cold-blooded animals, and their body temperature changes with the water temperature. Therefore, the changes in water temperature in different seasons greatly limit the range of fish activities.

Fish have different activity ranges in different seasons, and their activity locations change from time to time during the day. This is affected by changes in food and water temperature, and human interference cannot be ignored. Because there are many fishermen and tourists in some waters, fish survive in this environment and their anti-fishing instinct is enhanced. At the same time, they also become extremely alert.

Fish are greatly affected by the weather when foraging. When the weather is hot and humid and the air pressure is low, fish will become anorexic, and larger fish will hide in the water and not eat or move. On the contrary, if the water temperature is too low, the fish's metabolic function will slow down, and they will also refuse to eat. When the water temperature is suitable and the dissolved oxygen is sufficient, especially after the summer rain, the fish will become abnormally active, forage actively, and the bite rate will increase exponentially. When there is food in some places, the fish will transmit information to each other in a unique way and flock to find food. Once the reservoir is released, the water level will drop rapidly, and the fish will become terrified, hiding in deeper water and rarely eating. These are also the habits and characteristics of fish.

7. What are the eating habits of flamingos?

Flamingos eat algae and protozoa.

Flamingos' food mainly consists of aquatic algae, protozoa, shrimps, clams, small worms, insect larvae, etc., and they occasionally eat small mollusks and crustaceans.

The way it eats is unique. It bends its long neck and turns its head upside down. Then, it sweeps its curved beak left and right while walking, touching the bottom of the water to get food. Due to the special structure of its beak, the groove of the lower beak is deep, while the groove of the upper beak is shallow and lid-shaped. The edge has sparse serrations and fine hairs. When it is inverted in the water, it acts like a large sieve, which can quickly absorb and filter water.

Flamingo's life habits:

Flamingos like to live in groups, often in the tens of thousands. The lesser flamingo flock in Africa is the largest flock in the world today. In the Bahamas in Central America, which has an area of ​​only 13,939 square kilometers, there are more than 50,000 Caribbean flamingos, and even more than 100,000 of them gathered together.

Flamingos are not strictly migratory birds. They only migrate when there is a shortage of food or when the environment changes suddenly. Migration usually takes place at night, and they fly at a very high altitude during the day to avoid attacks by birds of prey. Migrating flamingos can fly 600 kilometers per night at a speed of 50 to 60 kilometers per hour.

The flamingos make deafening calls similar to those of geese. From a distance, their red legs look like a forest, and their long necks move alternately, which is very spectacular. They are gentle in nature, usually timid and alert, and their swimming skills are also very good.

8. Is loach not a fish? What are its living habits?

Simply put, fish swim with fins and breathe with gills throughout their lives. They are vertebrates that live in water all their lives. All of the above conditions are indispensable. Loaches meet the above conditions, so they are all fish. Loaches are classified as Cypriniformes and Cobitidae. Loaches are widely distributed in most areas south of the Liaohe River in my country, as well as in Vietnam and North Korea. Loaches are fish, but they also have special features that are different from other fish. For example, they are scaleless fish, that is, they do not have scales covering their bodies like other fish.

In addition, these two types of fish have a strong ability to survive in an oxygen-free environment out of water. I think this is the crux of your problem.

9. What are the elephants’ appearance, manner, diet, living habits, activities, and reproduction?

The main external feature of elephants is their flexible and muscular trunk, which can be used for winding and is a powerful tool for self-defense and feeding. The huge auricle not only helps with hearing, but also has the function of heat dissipation. The long tusks of males (both male and female African elephants) are specialized upper incisors. Asian elephants have 5 fingers on their forelimbs and 4 toes on their hind limbs, while African elephants have 3 toes on their forelimbs.

African elephants live in tropical forests, jungles and grasslands. They are the largest terrestrial mammals in existence. They feed on weeds, leaves, bark, twigs, etc., and drink 30 to 50 gallons of water every day. Their breeding period is irregular, with a gestation period of about 22 months. They give birth to one calf each time, reaching sexual maturity at 13 to 14 years old, and a lifespan of 70 years.

Elephants are diurnal and do not have permanent residences. Elephants are social animals, living in families with female elephants as the leaders. The time of daily activities, routes, foraging locations, and habitats are all under the command of the female elephants. Adult male elephants are only responsible for protecting the safety of the family. Sometimes several elephant groups gather together to form a large group of hundreds of elephants.

10. What fish are there in the Carl Ocean World Science Popularization Base and what are the characteristics of their living habits?

1. Spotted Bamboo Shark

The spotted bamboo shark is commonly known as the dog shark, dog shark, and sand shark. It is commonly found in the South China Sea and the southern East China Sea. It has both edible and medicinal value and is also an ornamental fish. Unlike sharks, the spotted bamboo shark is not active. It is a common small coastal bottom-dwelling shark that mainly inhabits coastal coral reef areas and often inhabits intertidal zones.

2. Three-toothed Shark

The three-tooth shark is also called the white-tip shark because of the obvious white tips on the first dorsal fin and the caudal fin. It is gentle and active at night. It can reach about 2 meters when it grows up. The three-tooth shark is a nocturnal animal that lives in the lower waters and usually rests during the day. With its slender and light body, it is good at moving in narrow crevices and holes on the reef, catching prey that other reef sharks cannot catch.

3. Blacktip reef shark

The blacktip shark is often called the "blacktip shark" because the tips of its fins are black or dark brown, and the front and back edges of the upper lobes of the pectoral fin and caudal fin are black. It is ferocious and is a common small to medium-sized shark in tropical and subtropical areas. It mainly inhabits shallow coral reef areas, intertidal zones, offshore waters, mangrove swamps, or estuary bays. It is easy to be confused with the blacktail shark because of its similar appearance, but you can tell them apart by whether there is a black tip on its dorsal fin.

4. Nurse Shark

The nurse shark is also called the "nurse shark". The word nurse comes from "Nusse", a common species of cat shark. People used to think that this shark belonged to the cat shark family, but later they found out that it was not. The pronunciation of "Nusse" is similar to "Nurse", so it is named "nurse shark".

The character of the "nurse shark" is just like its name, very docile and basically will not actively attack humans. It is considered the most docile shark in the world.
